Type
The type determines the overall layout of the hair dryer.
—
Pistol. The name of this variety is due to the fact that such hair dryers use a handle mounted perpendicular or almost perpendicular to the body of the tool — due to this, the tool itself is located in the hand like a pistol. This arrangement is the most popular today due to the fact that it combines ease of use, secure hold and safety for the operator. The main disadvantage of pistol hair dryers is less suitability for work in cramped conditions than straight ones; at the same time, for most tasks, their “passability” is usually quite enough.
—
Direct. Hair dryers of this type, as the name implies, have a straight shape — due to the fact that the handle is not located at an angle, but is a continuation of the body. This design is less convenient than the pistol, moreover, it requires the operator to be extra careful; Due to this, such models are much less common. On the other hand, they are indispensable when working in hard-to-reach places — a direct hair dryer is often able to get where a pistol one cannot reach.
—
Combined. This category includes hair dryers that can work both as a pistol and as straight ones. The technical implementation of such a possibility may be different: some models have a straight body and the possibility of installing an additional handle, in others the hand
...le is mounted on a swivel mount, etc. However, anyway, combined hair dryers are the most versatile, because. allow you to choose the option depending on what is more important for you at the moment — reliability and safety or the ability to work in tight spaces.Power consumption
The power normally consumed by the building dryer during operation. This parameter primarily determines the scope of the tool, as well as its performance, temperature and heating rate: more powerful models are better suited for large volumes of work, they produce a more intense air flow (see "Maximum Productivity") can be heated to higher temperatures and heating up is faster. At the same time, it must be taken into account that high power also has a downside: heavy weight, large dimensions and high cost of the tool, as well as a serious load on the power grid and significant electricity consumption. Therefore, when choosing by this parameter, it is worth proceeding from what work it is planned to use a hair dryer for and how important high power is for them. And don't forget about other features. After all, even the most powerful tool will be useless if it cannot provide, for example, the required temperature.
Max. performance
The maximum amount of air that a heat gun can pass through during operation. The higher the performance (at the same temperature), the more intensively the workpiece can be heated and the better the hair dryer is suitable for large-scale work related to blowing large surfaces. On the other hand, high performance usually requires corresponding power, with all the ensuing consequences (see "Power consumption"), and the need for large volumes of air is not always there. Therefore, when choosing, you should not chase maximum performance — first of all, you need to take into account the specifics of the tasks for which you plan to use a hair dryer.
Stepless air flow control
This option assumes that the volume of air supplied is regulated steplessly. The regulator is most often represented by a classic slider that directly changes the level of fan resistance, affecting the speed of rotation of the impeller.
Smooth flow control is necessary for a wide range of process operations, during which it is extremely important to avoid sudden (step) temperature changes.
Minimum heating temperature
The lowest air temperature that a heat gun can produce when operating in normal mode, in other words, the lower limit of the operating temperature range. Accordingly, the lower this limit, the wider the range, ceteris paribus, and the more versatile the tool: after all, for different jobs and temperatures, you need different ones. Some modern hair dryers have the ability to "cold" blowing, without heating.
Max. heating temperature
The highest outlet air temperature that a hair dryer can provide. As with the minimum temperature, this parameter determines how wide the operating range of the tool is and for what range of work it can be used. High operating temperatures are important not only for refractory materials — they can significantly speed up the processing of large surfaces. On the other hand, it is worth considering that for strong heating, appropriate power is required, which affects the weight, energy consumption, and often the price of the hair dryer.
Cold air mode
This option allows you to completely turn off the heating element, leaving only the fan running, or reduce the heating temperature to a minimum of 50 °C.
The cold air mode is necessary for cooling heated parts. For example, a stream of cold air will allow you to quickly cool the seams of hot melt adhesive. Most often, the cold air mode is represented by a separate position on the temperature mode switch, while cold air will be carried out at one single speed. But some models allow you to turn off the heating element by hardware, in which case cold blowing can be carried out in a wide range of speeds.
Brushless motor
The presence of a
brushless(brushless) motor in the design of a heat gun.
The name itself very clearly reflects the main feature of such electric motors: they do not have carbon brush commutators used in engines of a more traditional design. This reduces friction inside the motor, which saves energy and reduces heat. In addition, such hair dryers make less noise. However brushless motors are more expensive than traditional ones; on the other hand, this difference fully pays off both due to economical energy consumption and due to a longer motor life.
Stationary use
The model has a special support surface (usually placed on the back wall), thanks to which the product can be fixed in working condition on almost any flat horizontal surface. The possibility
of stationary use allows you to free the hands of the master during work. Due to this, the product can act as a stationary hair dryer and be used, for example, when bending plastic pipes.
