Need an industrial hair dryer. How to choose a building hair dryer and not be mistaken

A building hair dryer is a popular tool, which is unlikely to be replaced by something else. At first glance, it has a simple, uncomplicated design, but does this mean that choosing the right model will be easy?

This is a continuation of a series of articles dedicated to electric tools for professionals and amateurs. Today we will talk about heat air guns.

A technical hair dryer, as the “competent authorities” say, is also a blower, it is also a thermal gun, it is also a thermal blower, it is also a hot air gun, it is also a thermal wind blower, it is also a construction or industrial hair dryer ... This unit has a lot of names, most likely because of its remarkable popular popularity, the possibility of application in a wide variety of areas of life. And what, it is inexpensive, practical, compact, functional, easy to use.

A hair dryer is a device that works due to the flow of heated air. In German and French, there are words that roughly sound like "foehn" - a gust of warm wind descending from the Alpine mountains. The German company FOEN, which has been part of the AEG concern for more than a century, introduced the first hair dryer in 1900. Over time, the successful device was improved, acquired a number of additional properties and took its place in production workshops, construction sites, and home workshops.

What can a technical hair dryer

The list of operations that a hot air gun performs can be in the hundreds of items. In short, it is useful when local, safe surface heating is needed. In fact, a powerful professional building hair dryer will do everything that was previously done with a blowtorch, and much more. There can be one obstacle (in extreme cases, two) - if there is no power supply at the workplace, or it is raining, only then the lamps get some advantage. The assets of the hair dryer: the absence of an open flame, the possibility of the finest adjustments, safety, versatility, compactness.

So, what tasks are solved with the help of a thermal gun? We list the main ones:

• removal of heated paintwork, veneer, films, wallpaper, parquet, tiles;
• soldering and deformation of polymers;
• welding of linoleum, PVC fabrics and membranes;
• heating, melting and cutting of roofing material, bituminous tiles;
• work with soft metal solders, tinning, tin removal;
• installation of heat shrink insulation;
• soldering with tin or silver;
• acceleration of bonding processes;
• drying, blowing, cooling surfaces;
• defrosting of water pipes, steps, storm gutters and other elements;
• cutting of foam polymers;
• melting compositions;
• hot landing (pressing).

There is an opinion that a powerful building hair dryer can easily light barbecue coals and even create a magnificent crust on a gastronomic masterpiece. Some builders like to dry their wet robes with a blower, someone warms up the “brakes” for them, but still the main thing that is required of the average person is to “not confuse” the blower with a household appliance. It has been proven that whenever a technical hair dryer is used for other purposes, for example, for hairdressing purposes, it ends in disappointment. Manufacturers of this device persistently remind about this in passports and manuals.

Naturally, not all hot air guns are equally versatile, there are amateur models with limited capabilities, there are truly multifunctional devices with a large set of high-tech gadgets. Let's figure it out so as not to waste money.

Technical characteristics of the building hair dryer

The design and principle of operation of all technical hair dryers are approximately the same. In a case made of heat-resistant plastic, a spiral is located on a ceramic insulator, which brings the air to a predetermined temperature, and a high-speed electric motor with the help of one or two impellers pumps it in a certain direction. The nozzle in a special way forms the outgoing stream, which, in fact, does all the work. Of course, different products can have serious differences in layout, but more on that later. First, I propose to consider the "power" characteristics.

And these include the maximum temperature of the air jet and the amount of air supplied (productivity). As for the maximum operating temperature, on average for the class, this figure is approximately in the region of 600-650 ° C. It is these numbers that can most often be found in the name of the instrument (AEG PT 600 EC).

As always, there are exceptions to the rule - in nature there are monsters that heat the air up to 750-800 degrees. The performance of an average building dryer varies between 200-650 liters per minute, sometimes it can be regulated (Metabo HE 2300 Control). These characteristics are interdependent, they change their values ​​with almost every reconfiguration of the tool. A high-quality tool in this regard will be well balanced, the manufacturers of the cheapest models do not burden themselves with such things, they put everything together to the fullest, just to surprise the consumer. Obviously, the higher the maximum temperature and performance of the device, the more benefit it can bring to its owner. The reverse side of the coin will be a solid total blower power (500-2500 watts), which is distributed between the filament coil and the blower fan. Voracious devices exceeding 2 kW significantly load the electrical network and will be somewhat larger, heavier and more expensive. There are obscenely powerful models, for example, Steinel HG 5000 (3.4 kW, 800 l / min, max. 600 degrees; 1.2 kg).

Temperature regulation. This essential feature will help us to adapt to specific work with specific materials, which are now in abundance. It is no secret that even externally similar materials can have a special chemical composition, have unique physical properties, so each of them will require its own temperature regime. Building hair dryers of the "hobby" class are supplied with stepwise switching, usually these are two or three modes: "small", "near medium" and "maximum". Their scope is limited to materials that fall within these ranges. The situation is much more interesting with professional models - here it is possible to smoothly select the desired temperature, respectively, to work with any materials, even the most capricious ones. The temperature can be regulated either electronically (Steinel HG 2310 LCD) or using a slider.

Cold blow. Quite by the way, sometimes it is the ability of a building hair dryer to give out cold air (not all models have this). Thanks to this option, you can quickly cool, for example, a freshly welded joint of two plastic parts and immediately continue working. The total time for the entire project is reduced significantly. By the way, the supply of cold air can be carried out either by turning off the spiral (Bosch GHG 660 LCD), or through a separate nozzle. The second option is considered a serious technological breakthrough, but the first one also has its advantages - you can quickly cool the coil at the end of work and immediately put the unit in a case.

Maintenance of the set temperature. This system is called temperature stabilization by some manufacturers. Smart electronics reads information from a group of sensors and adjusts the power of the coil to specific conditions, but at the same time prevents it from overheating and failing (Makita HG 651). The temperature of the jet will be exactly what we need, regardless of power fluctuations in the network, strong winds or low temperatures of the treated surface, reflecting cold air. The built-in memory will play the last mode the next time you turn it on. It is much more pleasant to work with such a tool, the speed and quality of the operations performed increase. And the service life of the heating element increases markedly due to the absence of overloads and sharp dips in energy consumption. Unfortunately, household models cannot boast of such a wonderful option, primarily because of its high cost.

Filtration of incoming air. In some types of "air blowing" work, a certain amount of dust can be generated. It is sucked into the tool and, settling on the spiral, can cause it to fail. Advanced manufacturers supply their technical hair dryers with built-in removable filters that are easy to clean.

Control indication. To perform high-precision professional operations, when there is a danger of overheating (or “underheating”) the workpiece, it is necessary to control the parameters of the workflow every minute. All sorts of information screens, liquid crystal panels (Sparky HAG 2000ED) come to the rescue, which, however, do not make the tool cheaper. Most often, our services will be LED indication of various colors.

The layout of the building hair dryer

Pistol or cylinder? Typically, the blower has a pistol-type main handle (Makita HG 650 CK), which is why, in general, the “military” version of the name was assigned to it. The handle can be closed type, when the bracket protects the operator from hot air and particles of molten substance - this is the traditional option (Metabo HE 20-600). But there is also a direct layout (Bosch GHG 600 CE), maybe not so convenient and safe, but definitely more passable, allowing you to get to the tightest places (imagine that you need to clean a cast-iron radiator from paint). The Black & Decker KX1692 hair dryer has a swivel design and can, if necessary, take a straight or L-shaped shape. Anti-slip grips on the handle greatly increase comfort and safety when working with a hot air gun.

Parking options. Let's imagine the situation: the work is in full swing, and we need to take a minute break, for example, to fix a new workpiece on the workbench - the hot hair dryer needs to be put somewhere so as not to get burned and not to melt anything. The task is complicated by the fact that the hair dryer does not like falls even from a low height (the ceramics inside breaks, the spiral bursts). Putting the instrument “on the butt” is not always practical, even if the width of the platform is sufficient - it is very unstable. Putting the tool on its side is also not an option, there is always something nearby that strives to stick to a hot nozzle.

The solution turned out to be very simple - a special loop is made on the network cable, with which you can hang the unit on any hook. This device is useful if you need to direct the hair dryer to a certain area without much accuracy and hold it in this position for a relatively long time (for example, we need to heat up thickened bituminous mastic). We fixed the tool by the loop, and you can do other work. The body of the hot air gun can also have all sorts of hooks and supports for mounting on a flat surface (DeWalt D26411).

Burn protection. It is easy to explain why the cases of technical hair dryers are made of plastic - just metal in such a design (due to the high heat transfer coefficient) would be simply dangerous. There is no gearbox here, and plastic will be easier - in general, all manufacturers unanimously agreed on the use of polymer as the main material. The nozzle of the thermal air gun is still metal, because in all models it is closed with a thermal protective cover. The latter, however, somewhat limits the capabilities of the hair dryer in hard-to-reach places, because some manufacturers make it removable. Yes, work without a casing will require increased concentration and accuracy from the master, however, if necessary, the functionality of the device is significantly increased.

The nozzle can be equipped with a hot tip ejector (Skil Masters 8005MA).

Weight, dimensions, power cord. A building hair dryer is a manual tool, so it makes sense to pay special attention to its weight and dimensions. As a rule, heat guns weigh between 0.5-1 kg. It is also impossible to grind in this case, since such a difference in mass is seriously affected not only by the total power of the product, but also by the quality factor of the materials, the presence of a high-quality casing and a closed-type handle, a long and well-protected power cord. By the way, the longer the power cable is, the more convenient it will be to work (it is recommended to operate the hair dryer at the height of the chest / head in order to be less exposed to fumes). A cord shorter than 3 meters for a professional tool is a serious disadvantage.

Complete set of building hair dryer

Any technical hair dryer is equipped with a set of metal nozzles, they are also called nozzles, nozzles, nozzles. It is they who form the air flow in a certain way, which allows you to expand the capabilities of the tool. Usually, you can buy the necessary nozzle for any blower model, since they are quite inexpensive, and their range is in the tens of units, depending on the shape.

For soldering and heating copper pipes, sealing products with welding tape, round, focusing nozzles are suitable. Flat nozzles will cope well with the deformation of flat plastic, the removal of coatings (wallpaper, veneer, varnishes, paints). For deformation of polymer pipes, a reflector nozzle with a frontal rounded outlet is used, it heats the part from both sides, therefore it is also suitable for pressing, heating heat shrink. Slit nozzles help to overlap PVC sheets. The cutting nozzle is made in the form of a narrow flattened tube, it concentrates hot air at one point - it is designed for straight or figured cutting of foam polystyrenes (polystyrene, XPS ...). To clean window frames, when there is a danger of overheating the glass, nozzles of the "side design" - glass protection nozzles are used. The flat V-shaped nozzle is designed to feed the welding cord. Mirror nozzles return the reflected heat to the working area, serve as a heating surface for resistance welding of plastics. To switch from a gun to nozzles of a thinner diameter, reducing adapters are used, they also work as concentrating nozzles. We have listed the most common nozzles, the list is actually very long.

The basic package of a building hair dryer, in addition to nozzles, may include scrapers, additional handles, welding rods, pressure rollers, adapters and, of course, a case. Some manufacturers put the entire gentleman's set in a metal box, which is very far-sighted, given the weak resistance of hot air guns to mechanical stress.

When choosing a technical hair dryer, clearly indicate its scope. Inexpensive models from world leaders, including the hobby class, are suitable for most jobs. Excellent building heat guns are made by Makita, Bosch, Skill, Steinel, AEG, Kress, Metabo, DeWalt, Sparki, Black & Decker. The cheapest units without a name, as a rule, do not even work out their meager price, they are unsafe and have little functionality.

A building hair dryer, the characteristics of which will be described below, is a tool designed for welding linoleum, melting soft tiles and cutting roofing felt, etc. If you decide to choose such equipment, you should know its characteristics and the main factors that you should pay attention to .

Features of the building hair dryer

A building dryer, the characteristics of which you should study before purchasing the unit, is used to dry putty and glue, tiles or stucco, as well as joints of materials before laying insulation. With it, you can remove excess paint or varnish, wallpaper, parquet or tiles from the surface of furniture, floors or windows. To do this, you will need to stock up not only with the described tool, but also with a scraper spatula.

The hair dryer is used to form polystyrene PVC products (at an exposure temperature of 300 degrees). If you provide a temperature of 500 degrees, then you can also work with plexiglass, as well as acrylic. Perfectly copes with the appointment of rods and pipes made of polyurethane.

A construction hair dryer, the characteristics of which should be known to the consumer before going to the store, will help defrost icy locks, pipes and drains, removing ice from wires and steps. Through this unit, you can disinfect wood, eliminate microorganisms, bugs, destroy anthills that are built in a blind area or a stone wall. With it, you can glue various large parts using contact hot glue.

Among other things, a hair dryer will help speed up the setting of two-component compounds, remove PVC-based stickers, and also allow you to remove a screw that has been fixed with adhesive. A construction hair dryer, the characteristics of which may differ for different models, will allow you to solder and press it in, provide the necessary shrinkage to the hoses and handles. Using this tool, you can overlap the elements of a PVC film, as well as a tarpaulin.

Separate pieces of flooring can be welded together if they are made of PVC.

Specifications

If we consider the structures, they practically do not differ from each other in this respect. An insulator made of ceramics, together with a heating element in the form of a spiral, which is located in the insulator, are in a fairly durable plastic case that withstands high temperatures. In addition, the unit has an electric motor equipped with one or two impellers. The motor operates at a fairly high speed.

If you decide to choose the described tool, then it is important to take into account the maximum temperature that the air jet produced by it will have. The maximum temperature for most models is at around 650 degrees. However, on sale you can also find more powerful units, in which this parameter reaches 800 degrees. The performance of the device is determined by the volume of air that is passed through the hot air gun for a certain amount of time. If you have a middle-class model in front of you, then this value will vary from 200 to 650 liters in one minute. The parameter is associated with As the temperature and productivity increase, the tool will have a greater range of capabilities. Its power is determined by the power of the fan and the spiral. Power can be in the range from 500 to 2500 watts. If you want to choose equipment with a power of more than 2000 watts, then you need to be prepared for the fact that the unit will be quite heavy, bulky and expensive. For home use, a model whose power does not exceed 2000 watts is quite suitable.

Air volume adjustment

The building hair dryer, the photo of which you can see in the article, has one very important indicator, which is the adjustment of the volume of injected air.

Not all models are equipped with this functionality, but it can be extremely useful if overheating of the entire surface is undesirable. This function is also used if a fairly light part is to be air-treated, which can simply be blown away by too strong an air stream.

Heating temperature

If you choose a building hair dryer, the photo of which you can see in the article, then it is important to consider whether the tool has the ability to adjust the heating temperature. This parameter allows the master to adapt the machine to work with different materials. If you have hobby equipment in front of you, then the adjustment will be carried out in steps. As for building models, their adjustment is smoother. With the help of such a unit, it will be possible to work with any material, even very complex during processing. If you still need such functionality, then you can choose the adjustment method, which can be slider or electronic.

Temperature maintenance system

Before choosing a technical building hair dryer, you need to pay attention to the presence of a system for maintaining a certain temperature. Otherwise, this parameter is called heat flux stabilization. It is carried out on an electronic circuit and allows you to maintain a certain temperature of the forced air. This functionality saves the heating coil from rapid wear. Most often, manufacturers provide such devices with a memory that remembers a certain temperature until the next turn on. According to experts, working with such equipment is faster and more comfortable. However, as a rule, these are professional models that are quite expensive. For those craftsmen who choose a tool for solving everyday problems, most likely, such a unit will not work.

Use of cold air

Before choosing a building hair dryer for home use, you need to consider whether you need functionality that involves the possibility of blowing cold air. This option can be quite a big advantage. For example, after the place of soldering of plastic-based pipes has been cooled, the period of manipulation can be reduced. In this case, the master does not have to wait for the hot place to cool down by itself. When choosing a similar model, you should take into account that different options can provide cold air in different ways. This can be done by having another nozzle or turning off the helix. The first method is more modern, while the second allows for a short time to cool the coil after work, when the unit is already folded and packed. Among other things, the presence of another nozzle, which provides a supply of cold air, allows gluing thermoplastic surfaces - while the first nozzle will heat up, the second one will cool the surface.

Inlet air filter

Before choosing a building hair dryer for your home, you need to consider that the tool may have a special filter designed for incoming air. If you will use the equipment in places where there is a lot of dust, then this parameter is very useful. Once inside, contaminants can quickly disable the coil. Whereas if the air passes through the filter, then this problem will not arise.

Control indication

If delicate work is being done, too little or too much heat may damage the parts. In this case, it is necessary to constantly monitor the temperature of the discharged air. Control indication can be carried out using a small screen or by means of LED backlight.

overheat protection

If you choose a hair dryer, you should study the characteristics, reviews of a particular model first of all. Remember also that it is important to choose a model that provides protection against overheating. This function is also called a thermostop and is designed to disable the thermocouple in case of overheating. This can happen when it is necessary to work perpendicular to the surface of the material. Air goes to the base, then repels, affecting the spiral. This can cause the unit to overheat.

A building hair dryer is similar to a regular hair dryer that emits warm air. Only it is many times more powerful and is used during repair and construction.

With it, you can:

• produce synthetic wall decoration;
• remove stickers;
• remove vinyl coverings;
• remove coatings containing varnish or paint;
• peel off synthetic-based carpet tiles;
• do heat shrink treatment;
• soften or melt resin, solder, bitumen, wax;
• solder thin-walled copper pipes;
• create a mold from plastic and plastic pipes;
• weld PVC film;
• bend a wooden part;
• get rid of air spots when sticking films.

The device and principle of operation of the building hair dryer

The design includes a ceramic insulator, inside of which there is a heating mechanism - an air heating coil.

A powerful electric motor is inserted into the body, which blows warm air out of the coil and provides not only performance, but also protection against overheating.

It works like this:

• when you turn on the tool in the network and start it, the heating of the spiral turns on;
• with the help of an electric motor, air is sucked in, passes through a spiral and is blown out;
• depending on the power, the degree of heating of the spiral is regulated, and, consequently, the heating of the air.

How to choose a building hair dryer

To choose the right tool, you need to decide exactly where and for what you will use it.

• Building hair dryers are divided into two types: professional and household (normal). The first one has switches for operating modes: minimum, medium and maximum.

But it is better to choose devices where you can independently set a certain degree.

• When choosing, you should pay attention to protection against overheating. The function will avoid tool breakage in case of long-term operation.
• A heat shield would also be helpful. It is better if it is of high quality and removable.
• You should pay attention to the handle, which is of two types: open and closed. The second type provides better security and ease of use.

Basic parameters and varieties

• Tools differ from each other in technical characteristics. Power usually varies from 1600 to 2300 watts;
• The operating temperature of the I/II stages varies from 25 to 350°C and from 500 to 800°C (some models operate in 3 modes);
• Air flow rate I/II stages - minimum 150 and maximum 700 l/min;
• The presence of temperature control and air flow;
• Additional nozzles (from 2 to 4 pieces);

Choosing a model of a technical hair dryer with a built-in thermal protection option, you can count on a long period of operation, since the heating element is protected from unwanted overheating. The tools differ in the shapes and sizes of the handle - they are in the form of a pistol and cylindrical. The second option allows you to work in hard-to-reach places.

Purpose and scope

Hair dryers are used to warm up:

• thermoplastic parts for the purpose of soldering and giving them the necessary shape;
• paintwork with its subsequent removal;
• frozen water pipes.
