A construction hair dryer or thermo gun is a very important tool in the conduct of construction work that can be used for:
- welding and cutting of plastic products and pipes, as well as various films,
- softening to bend plastic products, roofing material or linoleum,
- hot seam weldingin the flooring,
- singing wood items,
- removing old paint on different surfaces,
- glue hardening duration control,
- warming up of car enginesth,
- drying out of hard-to-reach places.
The advantage of this tool is the absence of an open flame in it, which is important when working with combustible materials, the possibility of adjusting the power of the air flow and adjusting the temperature. Today we will talk about how to choose a reliable construction hair dryer and consider popular models.
Basic parameters for the selection of
The main parameters that should be taken into consideration when choosing a thermal gun include its power, the temperature of the output air flow, and also the productivity.
- Building hair dryers can have different power, which, as a rule, is in the range from 930 to 2300 W. The speed of operation and the scope of a particular instrument are determined by its power.
- The temperature of the air emitted by the construction hair dryer may range from 100 to 650 ° C.
- The performance of a hot air blow dryer determines the heating rate of the parts. Depending on the mode, the thermo gun is capable of delivering 200-650 liters of hot air per minute.
Additional selection parameters for
The main additional parameter of choice is the possibility of temperature regulation .On some models, a smooth adjustment is installed. The presence of this adjustment makes it possible to maintain the air temperature at a certain level and protect the instrument from overheating, thereby prolonging the life of the hair dryer. Smooth adjustment allows you to work with materials whose properties differ slightly.
If there is no smooth adjustment, the technical dryer can operate in several fixed modes. In such a case it is necessary to choose such a thermo gun in which there is the greatest number of modes, since with increasing number the range of those works that can be performed with the help of this tool expands.
In professional models of hair dryers, there is often an electronic temperature support system , which maintains the set temperature, regardless of the load.
When choosing a building hair dryer, you should take a closer look at its handle , which can be closed or open. The dimensions of a hair dryer with an open handle are smaller, and a closed handle provides protection of the hand from hot air and hot splashes of material that can melt.
If the fender has a heat-shielding casing protecting the nozzle from which air is supplied, it will be an effective protection against possible burns.
An important parameter of a construction hair dryer is the cold air supply function , which makes it possible to cool the glued surfaces without waiting for their natural cooling. For the supply of cold air, there may be a separate nozzle or it can be fed through the same nozzle as the hot nozzle. The second option is preferable, since the cooling of the hair dryer after heating takes 1-2 minutes.
The most complete use of the functionality of the tool is provided by the nozzles .The tool kit should include a flat nozzle( for separating, defrosting and drying the paint), a narrow nozzle( for welding films), a cutting head( for cutting foam), a round tapering nozzle( for air concentration), protecting the nozzle( for working with sensitivematerials).
The presence of the suspension hook or stand is an important element that provides fixing tools during breaks.
The length of the cord should be at least 2.5 meters, which will allow you to work with the tool without bending.
Selecting the model
The choice of the model of the thermopilelet is determined by the purposes of its application. A simple model, which has a small capacity and a standard set of attachments, will be quite sufficient to perform work in the household volume. In the event that more specific operations are to be taken, preference should be given to a tool of greater power, to which special nozzles are attached. If a significant amount of work is to be done, professional models of thermo-guns will be more convenient.
The most popular models of
thermal guns With professional models of Bosh building paints, you can make long work without interruption. In most hair dryers of this brand there is a smooth temperature setting function and a removable thermal protection. The model GHG 660 LCD has a liquid crystal display, which displays the temperature of the airflow, which can be fed in two modes.
Makita construction dryers with high performance are widely used in various types of work. They are used in welding, when removing layers of old paintwork, when cleaning surfaces. The model HG 6502 CK has built-in electronic memory, seven operating modes, the possibility of individual programming, as well as a system to protect against contamination and overheating.
Hammer Thermal Guns offer an optimal balance of price, reliability and operational simplicity. In the professional model HG2000C PREMIUM there is electronic thermal protection, allowing you to work continuously without worrying about overheating of the instrument.
Representative of worthy domestic brands of building hair dryers is Interskol. Model Interskol FE2000 ED is professional and has a digital display. The minimum temperature of the air flow is such that you can safely work with heat-sensitive materials. The maximum power is sufficient for efficient heating of the surface layer of large parts.
The price range of these instruments ranges from one and a half to seven thousand rubles. Hairdryers of inexpensive models have low power level and step-by-step temperature control. In professional models there is a removable heat shield, a set of a large number of nozzles, as well as cold blowing and a smooth temperature adjustment.
