A compressor is a mechanical device that compresses gases (increases their pressure by reducing their volume). The generally accepted classification of these machines is by the way they increase the pressure of the gases. According to their operating principle, compressors are divided into piston and screw.
Piston compressors can be single-acting or double-acting. They are available with or without lubrication.
Screw compressors consist of two massive screws facing each other with opposing threads, also rotating against each other. The gap between the screws is sealed with oil.
We will focus on piston compressors in more detail, since the ones we offer are of this type.
PISTON COMPRESSORS
Piston compressors are the oldest and yet still the most widely used type of such devices. They are characterized by a simple and compact design, high efficiency of the compression process and relatively low price. All design modifications are characterized by the conversion of the rotary motion of the engine into reciprocating motion of the piston. They are produced in single-stage or multi-stage versions, with air or water cooling.
If the inlet pressure is assumed to be equal to atmospheric, depending on the maximum outlet pressure of the reciprocating compressors, they can be divided into several groups.
PISTON COMPRESSOR GROUPS
- Low-pressure compressors: they compress the gas to 15 bar. Such pressure is necessary for various pneumatic tools, pneumatic drive systems and pneumatic automation, and a number of other devices. Such machines are most often called general-purpose compressors, are produced in large series and are the most common type. They are precisely those included in our nomenclature.
- There are also medium and high pressure compressors, as well as ultra-high pressure compressors, which are used on an industrial scale.
AREAS OF USE
The main type of work in which compressors are used is in the application of paints, primers and varnishes, especially on a large scale, such as in the painting of cars. Compressors are also used for blowing out various devices and components. In some applications (medicine, pharmacy, electronics, food industry, etc.), the presence of oil in the compressed gas is not allowed. Oil-free piston compressors have been developed for similar purposes. This is exactly the type that we offer.
They are characterized by a compact design, low weight and are easy to carry and service. They are suitable for home and garage use, and are extremely easy and convenient to use.
