10 tips for choosing a building hair dryer

Building hair dryer - this is very multifunctional a tool that really can do a lot. All its advantages have probably already been experienced by people who are professionally engaged in construction, repair or installation works. If you have a task, how to choose a building hair dryer, which will have the necessary set of functions and in the future will fully justify your needs and costs, for a start you should understand the types and functions of this tool.

1. General

Building hair dryer found its application in various areas of human life. It is a device that works with heated air flow and is designed to heat various materials when performing construction and installation works. Important feature A hairdryer is its ability to direct the flow of hot air exactly to the desired location. Temperature the heated air flow reaches 300-500 ° C, but there are models that have lower temperature conditions, for example 50 ° C. Design this device is very simple. An electric motor, a heat-insulating casing and a heating element are mounted in a housing made of durable plastic. The electric motor runs on very high elements and distills the heated air to the nozzle, which creates a directed air flow. There is a start button on the handle, and the cord at the outlet of the case is equipped with special protection against kinks. Performance a building hair dryer is determined by the volume of air passed through the device per unit of time. Some models are equipped with the ability to adjust the volume of forced air. This very convenient feature will be very useful if you work with small parts that can blow off a strong air stream. Another very important parameter - this is the ability to adjust the heating temperature. This makes it possible to use the device as accurately as possible when working with various materials.

2. The purpose of the building hair dryer

With this tool you can perform a large number diverse works having spent some time. Application and exploitation this device is very simple, but its performance and efficiency are significantly higher than when using many other improvised tools.

• You can easily remove layer old varnish, paints, of wallpaper and other materials from any surface, using a special spatula-scraper. A stream of hot air will melt the old coating, and you can remove it much faster than other methods.
• Highly quickly to dry thick layer putties, glue, tile joints, decorative stucco molding or places of connection of parts before performing insulation will also help a building hair dryer.
• Create the necessary configuration from polyvinyl chloride or polystyrene materials, pipes, rods made of polyurethane, acrylic and even plexiglas, you can use a stream of hot air of various temperatures.
• To make thermoplastic protective coating for wires and cables, a construction hairdryer is also useful.
• For defrosting icy drainpipes, locks, wires or steps.
• For disinfection wood. The flow of hot air will help get rid of insects and microorganisms that can inhabit the wood.
• For bonding overall details by increasing the exposure time and local heating of the connection.
• For dismantling obsolete fasteners filled with varnish, paint, glue or other substance that is difficult to remove mechanically.
• For commissures polyvinyl chloride pipes.
• When repairing a roof a building hair dryer will help to weld roofing materialoverlapped or cut roofing materials.
• Use while hot air speed up bonding.
• Can execute pipe repairusing tin or silver solder.
• Solder or solder copper pipes, wires or cable.

As you can see, we did not deceive, arguing that it universal tool. It is definitely useful both on the farm, when performing repairs or wiring replacement and water pipes, and in professional activities. the main thing - select the required temperature and air flow rate. It is these parameters that are the key criteria by which different types of hairdryers are distinguished.

3. Classification according to purpose

Depending on the temperature range and the intensity of the load during operation, emit three major of type building hair dryers:

• Domestic. This device is designed for a small amount of work. The maximum duration of continuous operation of such a tool is no more than 15 minutes. For instruments of this type, usually, there is no function of stepless temperature adjustment, and the maximum temperature of heating the air flow reaches 500 ° C, in rare cases - 560 ° C. Benefits Such an instrument consists in its affordable price, ease of operation and minimal power consumption. TO disadvantages include a short period of time continuous operation, low power and a small set of additional functions.
• Professional A hairdryer is used for many construction work. Such models have a function of smooth temperature control and stabilization of the temperature regime. The heat-insulating casing of such a tool can be removable, and the handle will be closed. TO the benefits can include the versatility of such hairdryers. Disadvantage will be the cost of this equipment.
• Industrial The hair dryer is used for extensive and intensive construction work. This is the most complete tool. is he possesses all affordable the functions This equipment has the highest heat flux temperature - 700ºС and its maximum power - more than 2 kW. And most importantly, it has the ability to continuously operate for a long time. disadvantages such a tool also has - this is its high cost and significant weight, as well as high energy consumption. But, this equipment can cope with any task.

Which building hair dryer to choose? It all depends from personal needs. Reasonably evaluate the need for certain functions. This balanced approach will help you significantly. to save.

4. Types of building hair dryers

Depending on the design of the building, building hair dryers are divided into three kind of:

• Straight The hair dryer does not have a special handle. It is replaced by the back of the direct housing, for which the tool is held during operation. Such a device has a very low weight and compact dimensions, which allows it to be used in a limited space. However, due to direct contact with the case, you may be exposed to electric shock, which makes the device less safethan a pistol or combination hair dryer.
• Pistol view has a handle located perpendicular to the axis of the housing. This is the most safe and reliable during operation appliance. But its use will be difficult in limited conditions.
• Combined view is "gold» the middle, between the first and second type of building hair dryers. Its handle can be removable or rotatable, which makes its use universal, regardless of operating conditions.

In turn, the hair dryer handle is divided into two types:

• Closed the handle complicates the work with the tool in a limited space, however, it protects the hands of the worker from damage by the flow of hot air, particles of processed materials, as well as from contact with a heated surface, which makes the use of a hair dryer safe.
• Open the handle does not constrain movement and does not create restrictions when working in hard-to-reach places, but when working with such a tool you need to be very careful and attentive, because your hands are not protected from burns and other injuries.

5. Key Features

Any type of building hair dryer has a number of testimony, defining it potential opportunities and scope. Allocate three major indicator:

• Maximum power. This is an indicator that determines the effectiveness and speed of a tool. The hair dryer, which has more power, is able to pass a large amount of air through itself, it warms up faster to the required temperature and works with higher temperatures. Accordingly, using such a tool, you can perform large volumes of work in a short period of time. The power of building hair dryers varies from 930 to 2300 watts, depending on the area of ​​their application. For example, a power indicator for household tool reaches maximum 1750 watts, professional fenov - to 2000 watts, a industrial – more than 2000 watts.
• Maximum flow determines the performance of the device. In other words, this is a certain amount of air that a hair dryer passes through itself for a certain period of time. This value is measured in liters per minute (l / min). The higher this indicator, the higher the productivity of the tool, and the faster it is able to heat the surface to be processed to the required temperature. For household hairdryers maximum flow rate is 450 l / minfor professional – 500 l / min, and for industrial - more 650 l / min.
• Maximum temperature. This indicator directly depends on the maximum power indicator. Therefore, the higher the power of the hairdryer, the higher the temperature of the air stream. Household appliances are able to heat the air flow to a maximum 500ºС, sometimes 560ºС. Professional devices give an indicator 650ºС, a industrial – 700ºС. When choosing a hair dryer do not forget about minimum temperature on which the tool can work. For example, for paint drying or cooling of soldering spots, low temperatures are needed, which are not available on all models.
• Weight building hair dryer is an important indicator, which affects the duration of continuous operation tool and ease of use. Working with heavy and large-sized devices is fraught with the rapid onset of fatigue, which means that the duration of the working process will be short, and lightweight devices, as a rule, have low power indicators. Optimal the option is to use a hairdryer with an average weight, which has sufficient power. The weight of building hair dryers ranges from 500 g to 1800 g. Medium models have a weight of 1000 - 1200 g.
• Operating modes. Construction hair dryers have two main and one additional mode. First - work at a minimum temperature, second - maximum air flow temperature, additional - cold blowing mode. This mode helps to cool the device after prolonged use or on a treated surface. Not all models are equipped with this mode.

6.Additional functions

For the convenience of work With a construction hairdryer, this appliance can be equipped with a number of additional functions. In the first paragraph, we mentioned the function of adjusting temperature and speed. Now we explain in more detail:

• Temperature adjustment. This function allows you to change the temperature of the air flow depending on the need when performing various tasks. It can be of two types - smooth and stepped. Continuous adjustment does not have clear positions in a particular place. That is, you can more accurately set the desired temperature. Visually, the controller resembles a radio slider, which scrolls when you search for the desired radio station. Models with this type of adjustment more expensive and mainly serve for professional use. Step-by-step temperature control has a fixed regulator position. Models with such a regulator cheaperHowever, less accurate. Well suited for simple household tasks.
• Speed ​​adjustment serves to control the flow rate of hot air at the outlet. Availability of this function makes operation building hair dryer more universal, since you have the opportunity to adapt to various details and materials.
• Stabilization of temperature. A very useful feature that allows you to keep the air flow temperature constant even under the influence of various environmental factors. For example, voltage drops in the electric network will not affect the operation of the device. In the presence of this function occurs auto tuning air temperature at the exit, without overheating at the same time the processed surface or details. In addition, this function protects heating element from premature failure due to overheating.
• Built-in memory. This function is equipped with the most expensive models of building hair dryers. It remembers and plays back the last used mode. Same protects the device from overloads and extends its life.
• Thermostop. In other words, protection against overheating. Certainly required functionwhich will extend the life of your equipment. When using a hairdryer, when it is perpendicular to the work surface, the heating element can often overheat due to reflection from the material back onto the spiral. In the presence of a thermostat, the thermocouple simply turns off.
• Filtration incoming air. This feature is significantly extends service life device, as small particles of debris and dust are delayed at the entrance, on a special filter, which is very easy to remove and replace or clean. This prevents contamination of the internal cavity of the dryer.
• Control indication. It can be a small display or LED backlight. This feature will be useful when professionally using a hair dryer and performing responsible and precision workwhich require constant temperature control, but it is not permissible to overheat or insufficient heating of the treated surface.
• Thermal protective casing, which is located on the pipe through which air enters, can be like removableso and fixed. is he will protect the hands of the worker from burns, and the removable type will be convenient when used in hard to reach places.

7. Options

Basic equipment a building hair dryer, in addition to nozzles, may include special scrapers, additional handles, adapters, welding rodscase. Most important of all of the above, are precisely nozzles. They are form certain flow air required for various jobs. By changing the options for air flow, you can expand the capabilities of the device and its scope.Nozzles are cheap consumables, which in case of loss or breakage can easily be replaced with new ones. There are many options for the execution of nozzles, depending on the needs of the user. We'll consider the most the main:

• Round nozzles are best used for soldering or heating copper pipes or sealing products using welding tape (No. 1 in the figure)
• Flat nozzles are used to remove old coatings, for example, varnishes, paints, wallpapers, veneers. Or for deformation of thin plastic (No. 2)
• Reflex nozzles are used for deformation polymer pipes. They have a frontal rounded bend that heats the pipe from two sides. Such a nozzle is suitable for pressing and heating shrink (No. 3)
• Slotted nozzles facilitate gluing of a PVC sheet overlapped (No. 4)
• Cutting nozzles look like a narrow flattened tube. It creates a concentrated, accurate flow of heated air, with the help of which it is possible to perform cutting or figured cutting of polystyrene foam (No. 5)
• Side nozzles are very convenient for removing paint coatings from window frameswhen overheating of the glass is unacceptable (No. 6)
• Mirror nozzles are used for welding plastic materials. The heat from the air flow is returned to the part using a mirror (No. 7)

Another useful feature is auxiliary the loop. This is rather related to the design features, but nevertheless, it is a very convenient addition. When mixing and heating solutions, you can suspend the device at the required height and do the job with two hands. It can also be useful when it is necessary to direct the flow of heated air to a certain place for a long time. Special hooks and supports help to install the equipment on a flat surface at the required angle. These two functions determine the parking method tool. Do not forget about the storage location for your device - a special case. Use it during transportation significantly extend the life of your appliance.

8. Recommended manufacturers

When buying such a serious and versatile equipment in no caseshould not save on its value. There are several manufacturers who have proven themselves to be very worthy of the quality of the materials used and have repeatedly confirmed their reliability and durability. remember, that cheap models of unknown manufacturers that have never been heard before, very quickly fail and even the money spent on them will not work. The cheaper device is due to the use of poor quality plastic, short-lived heating elements or electric motors. Such little-known manufacturers, which are unlikely to provide a long service life, include cheap models of brands “Zenith», «Elprom" or "Proton". From buying a hair dryer with that name is better refuse.

Well recommended such brands as Bosch, Makita, DeWALT, Steinel, Stern, DWT. These companies produce not only high-quality building hair dryers, but also much more equipment. In general, these brands are different high-quality assembly, security their tools, solid materials, reliable electronics. Naturally, the cost of such a hairdryer will be higher, but you do not have to regret the purchase, especially since for all the goods, you will definitely be provided with an official warranty card.

9. Tips for use

Any device needed properly and carefully use. Especially with a building hairdryer, as it’s actually a very fragile appliance that does not suffer blows, therefore, to fix the hair dryer in the required position, be sure to use special hooks or the loop that we wrote about.

Do not use the hairdryer near flammable liquids.Since most hairdryers fail due to overheatingwhat happens when using the appliance in a perpendicular position to the work surface, try to keep the hair dryer at an angle of 45 °. This will not affect the quality of the work performed, but will save your device from damage.

After finishing work, give the hair dryer completely cool off and only then put it in a case. Never leave the appliance running. unattended. When working with a hairdryer, do not forget about own safety. Never check the temperature of the airflow with your hands, this is inevitable will cause burns. When removing paints and varnishes always use special scraper and put on respirator. Ideally, work with a hairdryer on open the air or in a well-ventilated area.

10. Tips for choosing a hair dryer

The most the main thing before purchase - clearly decide from your personal needs and the intensity of operation of the hair dryer. If you purchase the device in order to carry out home repairs, then it is enough for you domestic models, if you plan to earn on this, then give preference to a more powerful professional models with additional features.

Be sure to pay attention to power cord length! Hair dryers that have a cord less than 3 meters in length will be very uncomfortable to use, and so you can get to all corners of the room, you will have to use extension cords in addition, which is not always convenient and appropriate.

When buying, pay attention to appearance device. Its body should not have scuffs, scratches, the joints of the parts should not have large gaps and backlashes. All elements of the device must fit snugly together. Check if the actual equipment goods declared in the instructions. Inspect all nozzles, adapters, and especially the power cord. It should not have excesses. Choose models with break protection. Ask the seller to demonstrate you working capacity device. And most importantly - just choose trusted manufacturers.
