Type 30 Compressors - Full Specifications

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.
