What is an Air Compressor Block?
Also called a reciprocating compressor block or bare piston compressor block, a compressor block is the part doing the compression of the air. A piston moving in a reciprocating motion within the cylinder compresses the gas. It is driven by an electric motor or another form of rotation. The pistons are moving up and down and compress the air from atmospheric pressure up to full tank pressure. As the volume decreases the pressure increases. The gas is then pushed out of the cylinder to the next stage of compression or to the discharge connection.
Refrigerated air dryers from 750 liters/min up to 6500 liter/min ex-stock. Larger ex overseas. Dew point 4°C under pressure. Automatic drain pre and manual drain after filters.
Screw compressors have no valves or other mechanical forces to cause imbalances unlike piston compressors.
Airpower keeps universal spare parts for compressors. Pressure switches, non return valves and safety valves are universal to all compressors. Bottom entry filters/ regulators, electric motors and starters can be used for many makes of compressors.
