Premium replacement pump heads and blocks for the industrial sector. Stocking ABAC, Chinook, and Type 30 variants.
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.
Airpower’s selection of Chinook Air Compressor Blocks are all made with solid cast iron for the wear and tear parts and aluminum parts. Our Chinook range is reliable and recommended for heavy-duty industrial applications

If the receiver, motor and supporting components are still in good condition, replacing the air compressor block can be a more economical option than purchasing a completely new compressor. An Airpower specialist can inspect your equipment and recommend the most cost-effective solution for your application.
Absolutely. Whether you’re replacing a worn compressor block or building a new compressor, Airpower’s experienced team can recommend the correct block based on your required pressure, airflow, duty cycle and application. This ensures you receive a solution that delivers reliable performance and long-term value.
Common signs of a worn air compressor block include reduced air output, difficulty reaching operating pressure, excessive oil consumption, unusual knocking noises, overheating, or increased vibration. If left unresolved, these issues can lead to costly downtime or damage to other compressor components. Having the compressor inspected early can help determine whether a replacement block is the most cost-effective solution.
Yes. Air compressor blocks are available for many leading compressor brands and configurations, provided the correct specifications are matched. When selecting a replacement block, it’s important to consider factors such as operating pressure, airflow, motor compatibility, and mounting configuration. Airpower can help identify the correct replacement for your existing compressor.
