Comparison Intertool DT-5001 vs Intertool DT-5060

— Airbrush. General purpose spray guns — in other words, traditional spray guns that do not belong to any of the specialized categories described below. At the same time, the functionality of such devices can be quite diverse — from relatively small tools for hard-to-reach areas and small areas to quite powerful performant solutions that are already approaching paint stations.

— Airbrush. A miniature variety of spray guns, distinguished primarily by very small nozzle sizes — less than 1 mm, and more often up to 0.5 mm. Thanks to this, airbrushes are optimally suited for delicate work, where accuracy is most important; with the help of such a tool, you can even create full-fledged paintings (for example, those same “airbrushes” that adorn cars).

— Roller. An improved version of the conventional paint roller, supplemented by a paint supply system. Thanks to this, additional convenience is provided during work: there is no need to periodically dip the roller into a container with paint, and the coating itself is applied as accurately and evenly as possible.

— Plaster. A variety of spray guns used not for painting, but for plastering. One of the characteristic features of such tools is the large diameter of the nozzle: thanks to this, it is not clogged with mortar particles and is easily cleaned after work is complet...ed. In addition, plaster guns are usually equipped with rather large (about 5 – 7 liters) own tanks; such a reservoir is usually supplemented with a handle for the convenience of holding the tool with the second hand.

— Paint station. Units designed for large volumes of work, where high performance is of decisive importance. A mandatory feature of paint stations are remote compressors (see below) of high power and large size, usually mounted on a stand or even a trolley for ease of transportation. And often there is no own paint tank at all, and the working composition is supplied from an external container (for example, a bucket). Also note that painting stations often allow two guns to be connected to one compressor at once (see below).

The power consumed by the operation of an electric tool (see "Type").

Most modern spray guns, even performant ones, have a rather low power: for example, models with more than 1 kW are extremely rare, and in most cases, power consumption does not exceed 500 W at all. So when connecting such equipment to sockets, there are usually no problems; only single units of high performance, requiring 3.5 kW or more, have to be connected according to special rules (directly to the shield). In other cases, data on power consumption is most often not needed for normal use and may be required only for specific tasks — for example, to calculate the load on an autonomous generator.

Nominal air pressure in the spray gun.

The general meaning of this parameter depends on the type of instrument (see above). So, in pneumatic models, nominal pressure data is required for connection to an external compressor. It is this pressure that this compressor must create at the inlet to the atomizer; too low values will lead to a decrease in efficiency, too high are fraught with breakdowns and even accidents with injury to others.

In turn, for electric models, the nominal pressure is the air pressure created by the unit's own compressor; the complete atomizer was originally designed for the same pressure. So in this case, this parameter is more of a reference than practically significant; it may be useful only for connecting replacement nozzles to the compressor (or vice versa, for using an existing nozzle with a third-party compressor).

As for specific pressure values, they are primarily determined by the spray system (see below). The diversity here is quite high: the most modest units give out less than 2 bar, 2-5 bar compressors are quite popular , 5-10 bar models are relatively rare, and some powerful performance solutions provide a pressure of 100 bar or more.

Nominal air flow rate when the spray gun is operating in normal mode.

This parameter is of key importance for a pneumatic tool (see "Type"): the compressor to which such a sprayer is connected must provide the appropriate air supply rate, otherwise normal operation will not be possible. In turn, in electric models, this indicator is more of a reference — the complete compressor, by definition, corresponds to the characteristics of the sprayer, and it makes sense to pay attention to the flow rate only if the working nozzle of the electric spray gun is planned to be used with a "non-native" compressor.

The diameter of the nozzle at the outlet of the spray gun.

It is from this nozzle that paint or other working material comes out. And the productivity and spot size at the exit depend on the diameter. Accordingly, larger nozzles are better suited for processing large surfaces, while smaller nozzles provide greater precision and accuracy. Thus, this parameter is directly related to the type of device (see above). There are also spray guns with a replaceable nozzle, when more than one nozzle is provided in the kit, which expands the possibilities of using the device.

The type of spray system used in the device. Different spray systems differ in the format of work and, as a result, in individual practical nuances of use:

— HP (High Pressure) / CONV (conventional). One of the most famous and popular spray systems. The air pressure at the inlet and outlet of such spray guns is approximately the same. The advantages of HP systems are the simplicity of design, large working width, high paint application speed and relatively low air consumption. At the same time, the percentage of paint transfer in such sprayers is very low — more than half of the applied material bounces off the surface due to high speed and settles on surrounding objects. Another disadvantage is that the flow from the HP atomizer picks up fine dust and other "flying debris" heavily; because of this, additional grinding and polishing of the painted surface is often required.

— RP (Reduced Pressure). Modification of conventional (HP) atomizers, characterized by a slightly reduced outlet pressure. This allowed for some improvement in the transfer coefficient and reduced debris levels while maintaining the advantages of good performance, uniformity and low air consumption. Nevertheless, according to these indicators, such devices are still inferior to low-pressure models.

— HVLP (High Volume Low Pressure). Spray system with reduced outlet pressure (a...pprox. 0.7 bar) and large air volumes. One of the key advantages of such devices is a high ink transfer coefficient of at least 65%. In addition, the low speed of the paint supply reduces the level of debris: there are relatively few turbulences that “pull” debris along with them. The main disadvantage of HVLP systems can be called high air consumption; not every compressor can handle such an atomizer. In addition, they require additional filters to protect against oil and moisture entering the air during high compressor loads; and you can work with such a device only at a short distance (usually up to 15 cm), and in order to avoid drips, a certain skill is required.

— HVLP-II (New High Volume Low Pressure). The second generation of HVLP (see the relevant paragraph), which has a number of improvements compared to the original, but is generally similar.

— LVLP (Low Volume Low Pressure) / Trans-Tech. Spray systems developed as an improvement to HVLP. With the same advantages (high transfer coefficient, minimum debris), they consume much less air and have softer requirements for compressors and hoses. In addition, LVLP systems are less sensitive to pressure drops, and the effective spraying range in them reaches 25 – 30 cm. Of the notable disadvantages of this option, one can only mention a rather high cost.

— HVMP (High Volume Middle Pressure). Spray systems with high air flow and medium outlet pressure. Compared to HVLP, due to the higher pressure, they give a slightly lower ink transfer efficiency, but greater uniformity and range.

— LVMP (Low Volume Middle Pressure). Spray systems with low air consumption and medium pressure; a kind of modification of LVLP, characterized by higher pressure. Due to this, the cost is somewhat reduced, productivity, uniformity of application and capture width are increased; however, paint consumption is higher and the finished surface is rougher than original LVLP.

— HTE (High Transfer Efficiency). This marking is used in spray systems for which a high transfer coefficient is claimed by the manufacturers. In terms of characteristics, they are most often similar to LVLPs (see the relevant paragraph) — in particular, they have a rather large effective range. However, specific features in each case should be clarified separately.

— EA (Excellent Atomization). The main feature of such systems, in accordance with the name, is a very high degree of atomization of the material. Other performance characteristics in such systems may be different, these points should be clarified separately.

— HEA (High Efficiency Airless). Proprietary airless spray technology (see "Spray") used in the Wagner brand technique. Reduces paint wastage by more than 50% compared to more traditional systems, as well as more even material distribution, according to the creators. Suitable for water and oil based coatings.

MP (Middle Pressure). Transitional option between the HP and RP described above: it provides a slightly lower working pressure compared to HP, but not as low as in RP. For a number of reasons, it did not receive distribution.

HD (Heavy Duty). A marketing designation used on individual sprayers, typically high-capacity, high-volume sprayers. The specific characteristics of such systems should be clarified separately.

The location of the paint reservoir relative to the regular working position of the spray gun. Note that there are models without a tank, and this indicator does not affect the quality of painting, the differences lie in other points:

— Lower. The lower arrangement allows the use of fairly large containers, while maintaining the ability to work with one hand. In addition, many models allow you to put the gun directly on the tank.

— Upper. The top position of the tank provides a fairly comfortable balance; and due to the fact that the paint enters the gun under its own weight, it becomes possible to work with more viscous materials than with the lower location. However the volume of the tank is usually less; the exception is plaster spray guns (see "View"), in which the tank is supplemented with a handle to hold the tool in two hands.

— Lateral (swivel). At first glance, such models look like overhead spray guns; however, in them, the reservoir is not connected directly from above, but from the side, through an L-shaped tube. The attachment of this tube allows you to rotate the tank, so that the spray gun can be used with equal convenience for both vertical surfaces (such as walls) and horizontal surfaces (such as the ceiling).

— Detached. Reservoirs located separately f...rom the spray gun and connected to it by a hose for supplying paint. This option is considered optimal for large volumes of work. There are several reasons for this: firstly, the user has to hold only a relatively light pistol in his hands, which reduces fatigue; secondly, the tank can be made quite roomy — up to several liters. Among the shortcomings, one can note the general bulkiness and increased cost of such spray guns.

The total volume of the paint reservoir supplied with the gun. Large tank, on the one hand, allows you to "charge" a lot of material and work for a long time. On the other hand, it increases the size and weight of the device; and a large amount of paint will also weigh accordingly (although for models with a separate tank location - see above - this is not critical). Therefore, the thinner and more delicate the work for which the spray gun is designed, the, as a rule, the smaller the tank volume : for example, in airbrushes (see "View") it rarely exceeds 50 ml, and in plaster models, in turn, can be measured liters. Therefore, most models have a volume of no more than a liter, namely 500 ml, 600 ml, 700 ml, 800 ml, 1000 ml.

The presence of a belt for holding on the shoulder in the design of the spray gun.

This feature is found mainly in models with an external compressor (see above). The sling allows the user to carry the compressor close to the gun, so the air hose does not restrict tool movement.
