Hot air is used in many construction or repair work. To form a stream of hot air with a temperature from 100 to 650 ° C use a construction or technical hair dryer. Sometimes he successfully replaces a blowtorch. The advantage of this tool is the lack of open flame and the ability to adjust the temperature of the supplied air. Technical hair dryer has a wide range of uses:
- Heating of plastics, roofing material and linoleum to increase elasticity during installation.
- Welding with films, plastic products, plastic pipes.
- Performing hot welding of the floor covering.
- Acceleration / deceleration of glue drying.
- Removing old paints from various surfaces.
- Firing wooden surfaces.
- Accelerated drying of surfaces or hard to reach places.
Such a wide range of works made this tool popular. There are some key points that you need to pay attention to when choosing it. The main technical characteristics that require increased attention: power, air flow rate and temperature range.
The power of building hair dryers varies from 900 to 2300 watts. The more powerful the technical hair dryer, the faster the work. The speed of heating of the workpieces also depends on the strength of the air flow or the performance of the air supply. This characteristic is usually in the range of 200 to 700 liters per minute. Another important parameter is the temperature of the supplied air. It varies from 100 to 700 about C.
Choosing a technical hair dryer, pay attention to additional functions that will be useful in your work. For example, the ability to adjust the temperature. The adjustment is convenient in operation: you can precisely select the temperature for each type of material. If you choose a model with a step switch, you need to make sure that there are the maximum number of operating modes. Many professional hot air guns have a built-in temperature control system. It regulates the heating of the air flow regardless of the load. This function avoids overheating of the tool and surface. Some types of work require quick cooling. There are models that have the function of supplying cold air.
Ergonomic details are also important. So, pay attention to the handle. Models with open handles are smaller, but a protective cover protects your hands from burns. Must have a protective coating and nozzle. In addition, the tool simply must be conveniently located in the hand: you will have to work for a sufficiently long period of time, and comfort is not at all superfluous.
For more efficient use of special nozzles. There are
devices for welding, drying, cutting and soldering. There is a special round nozzle that forms a directed air flow, and there is a protective one that will protect the heat-sensitive materials from overheating.
As with the choice of any equipment, special attention should be paid to the manufacturer: the appropriate quality should be attached to good technical characteristics. Bosch technical hair dryer received good recommendations. This manufacturer pleases with a consistently high level of performance and a large assortment that allows you to choose a tool for any purpose. From the products of domestic manufacturers can distinguish technical hairdryer "Bison". It is quite competitive in today's market.
