Comparison DWT HLP 20-600 K vs DWT HLP 20-550 K

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.

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 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.

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.

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.

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.

— Case. Cases are special containers designed for storing and transporting tools. Typically, such containers are made in the form of characteristic suitcases made of hard materials, with handles for easy carrying on the outside and nests for tools and accessories inside. In addition to protecting the contents from adverse effects (dust, moisture) and contact with foreign objects, such suitcases also perform another important function: they allow you to keep the hair dryer and its accessories in one place, reducing the risk of losing any of these items. . Improvised packages can also be used for such tasks; however, complete cases tend to be more practical and convenient.

— Scraper. Availability of a scraper in a set of delivery of the heat gun. The scraper is used in the processing of various surfaces, mainly to remove old paint, dirt, etc. The working part of such a tool has the form of a small plate, the edge of which scrapes over the surface to be treated.

It should be noted that in this case, it is the traditional hand-held scraper held by the user during operation. Among heat guns, there are often nozzle attachments that have a similar purpose, but they are not included in this category. Returning to the hand tool, we note that in some situations it turns out to be more convenient than a hair dryer with a nozzle. First of all, such devices are noticeably lighter and more compact, whic...h makes them very convenient for working in hard-to-reach places, as well as for work that requires precision and accuracy. Also, a hand scraper can be useful if the surface to be treated does not require heating.

— Spatula. The presence of a spatula in the delivery set of a heat gun. A spatula is a tool resembling a small spatula — it consists of a plate (most often metal) and a handle. This tool can be used for different purposes. So, in some cases, it can serve as a replacement for a scraper — a spatula can easily cope with putty, wallpaper and other coatings that do not require too intense exposure. Another popular use of such devices is the application and leveling of various coatings, primarily putty (which got its name from the spatula).

It is worth noting that in this case, the presence of a traditional manual spatula in the kit is implied; there are nozzle attachments for a similar purpose, but in this case they are not considered spatulas. In some situations, a hand tool is much more convenient than a hair dryer with a nozzle. So, the classic spatula has a small size and weight, thanks to which it handles well with work in hard-to-reach places, as well as where precise and accurate action is required. Also, this particular tool is best used in cases where the surface to be treated does not need to be heated with a hairdryer.

— Nozzles. The number of additional nozzles per nozzle supplied with the building dryer.

Interestingly, in this case, the most extensive configuration option is most popular — 4 pcs. This is due to the fact that nozzles are inexpensive, and thanks to them, the capabilities of the hair dryer are noticeably expanding. A smaller number — 2 pcs, 3 pcs, is noticeably less common, 5 pcs and more — almost never occurs.

Note that the design and purpose of the nozzles can be different, so these details should be clarified in each case separately. Traditional options include a constrictor nozzle, a reamer nozzle, a scraper nozzle, and a spatula nozzle. The purpose of the first two varieties is clear from the name — they are designed to configure the flow of hot air to suit the particular situation. Thus, the narrowing of the flow allows you to increase the intensity of the impact and reach hard-to-reach places, and the expansion speeds up the processing of large surfaces for which productivity is important. As for the last two types, they should not be confused with hand scrapers and spatulas (see the relevant paragraphs): we are talking about nozzles that are put on the nozzle. They are similar in application, but they have their own specifics of work: the metal plate (the working element of the scraper / spatula) is bent so that the hot air flow from the hair dryer is directed to the surface in front of the working edge of the plate. Thus, the spatula / scraper moves over the heated surface, which greatly facilitates processing.

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.
