A compressed air press is driven by a compressed air compressor. The controlled expansion of compressed air is widely used to drive air motors and tools such as pneumatic hammers, sandblasters and paint spray guns.There are various types of air presses. Frequently encountered drive elements include piston compressors and centrifugal compressors. In a piston compressor, the air is compressed by the movement of a piston in a cylinder. When the piston moves to the right, air flows into the cylinder via an inlet valve. When the piston moves to the left, the air is compressed and pressed through an outlet valve into a pressure accumulator.A gyro compressor, usually used for low and medium pressures, usually consists of a kind of impeller that runs in a closed round housing. Air is drawn in through the centre of the wheel and accelerated by the centrifugal force of the rotating blades. The kinetic energy of the air is then converted into pressure in the diffusion unit and the compressed air is then pressed into the pressure vessel via a bottleneck.The air heats up during compression because the air molecules collide more often in a smaller room. For this reason, the air on its way to the pressure vessel is cooled with water or air, for example. The compression to high pressures takes place in several stages.
