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.
Temperature adjustments
The number of outlet air temperature adjustments provided for in the design of the heat gun. The adjustment itself is an almost mandatory function for such a tool — after all, different types of work and different types of materials require their own temperature values, and without it you can either “underheat” or “burn through” the workpiece. The more adjustments provided in the design of the hair dryer — the finer the temperature settings, the easier it is to choose the mode that is optimal for a particular task. At the same time, it is worth noting that in this case we are talking about
step temperature control, while the most advanced option today is smooth control (see below).

The ability
to smoothly change the temperature of the air supplied by the heat gun. The meaning of temperature adjustments is generally detailed in the relevant paragraph above; here we note that smooth adjustment has a number of advantages over stepped. The main one is that the outlet temperature in such hair dryers can be adjusted very precisely, and at will, and not in accordance with the fixed values \u200b\u200bthat are set in the manufacturer's settings. Among the disadvantages of this option, one can note a higher cost than most step regulators — despite the fact that in fact high tuning accuracy is not required so often, usually in professional work.
Weight
The total weight of the tool. On the one hand, heat guns are held in the hands during operation, which means that a lot of weight is undesirable for them — heavy devices are less “agile” and tyre the operator more. On the other hand, too little weight can mean low quality materials, a small thickness of insulation and, accordingly, unsatisfactory safety performance. Therefore, in most modern models, the weight is at least 500 g, and in the most advanced models it can exceed 1 kg. Also note that some "heavy" hair dryers may have a design that allows you to install them on a flat surface during operation.
If there are additional nozzles in the kit, the weight of the tool without them is usually indicated.
