Comparison Worx MakerX WX742.9 vs Einhell TC-SY 400 P

— 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 type is indicated by the energy source from which the spray gun operates. Nowadays, you can find pneumatic, electric(mains and battery), as well as mechanical and gasoline models. Here are their main features:

— Pneumatic. Spray guns powered by compressed air from an external compressor. In other words, the delivery package for such a tool includes only a spray gun (gun, airbrush, etc.); it requires a separate compressor to operate. At first glance, this creates certain inconveniences; however, such a configuration also has noticeable advantages. Firstly, there is no need to overpay for a compressor if it is already “on the farm” (a separate example of such a situation is a construction site where a powerful stationary compressor is used for several pneumatic tools). Secondly, the nozzle and compressor can be selected at your own discretion, without relying on the equipment selected by the manufacturer. In light of this, most modern spray guns are made pneumatic. The obvious disadvantages of such devices include their unsuitability for working with airless spray systems, however, such systems are used much less frequently than air systems, so this nuance is not key.

- Electric. In this case, we mean wall-powered spray guns (battery-powered models are placed in a separate category,...see below). Devices of this type consist of the sprayer itself, as well as a compressor (built-in or remote). One of the advantages of this option is the presence of a compressor, thanks to which such a spray gun, in fact, only needs an outlet. In addition, such units can use both air and airless spray systems. The disadvantages of electric models include a higher cost than pneumatic ones, as well as the inability to select a working nozzle and a compressor separately - as a rule, spray guns of this type are sold in ready-made kits.

- Rechargeable. Spray guns equipped with electric compressors powered by their own batteries. The key advantage of such tools is their autonomy, the ability to work even in the absence of sockets nearby. On the other hand, it is difficult to achieve high power and performance with a battery; the continuous operation time of such sprayers is limited by the battery charge (and a source of electricity will still be required to replenish the charge); and the design itself is more complex and more expensive than that of analogues powered from an outlet. Therefore, cordless spray guns are not particularly widespread in our time.

- Mechanical. Units in which paint is supplied by the user’s muscular strength - in other words, to do this, you need to manually pump the pump lever. This operating scheme is as simple and reliable as possible, but it is poorly suited for traditional sprayers. Therefore, “mechanics” is extremely rare in our time, mainly among rollers (see “View”).

- Gasoline. Models with this type of power supply combine high power and independence from electrical networks, but they are quite bulky, more complex to operate and repair, more expensive (both in terms of their own cost and the price of fuel) and are generally designed for industrial use outdoors . Therefore, they are not widely used and are used where, for one reason or another, electrical analogues are not applicable.

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.

Consumption of paint or other material (for example, mortar for plaster) when the spray gun is operating in normal mode.

The higher the flow rate, the more material the tool can apply per unit of time, the better it is suitable for processing large areas and for applying thick coatings. On the other hand, not all types of work require high productivity, and sometimes relatively low consumption is optimal. Detailed recommendations on this subject for different situations can be found in special sources.

The maximum viscosity of the paint or other working material at which the spray gun is able to work normally. Specified in DIN units; a certain DIN in this case is the number of seconds it takes for a standard volume of paint (usually 100 mL) to pour out of a funnel with a strictly defined pour hole diameter (usually about 4 mm). Such a funnel (viscometer) can be supplied with the spray gun, but if necessary, it can be purchased separately.

Thus, the larger the DIN, the more viscous the composition is. And the larger the number indicated in the characteristics of the spray gun, the wider its capabilities, the thicker liquids can be poured into it without fear of clogging and breakage. At the same time, it should be taken into account that in fact it is not so often necessary to work with thick liquids — on the contrary, excessive viscosity worsens the quality of the coating, leads to streaks and increases the drying time. For example, most enamels and oil paints are used at a viscosity of about 20 DIN, latex paints up to 45 DIN, etc. General recommendations on this matter can be found in special sources, and specific ones can be found on the packaging of a particular brand of paint or other composition.

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 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.
