Engine-Driven Reciprocating

Gas/Diesel

Industrial gas and diesel engine-driven reciprocating compressors deliver air power for field and remote work. With the capacity to run 1-inch impact wrenches along with any assortment of air tools, these are the units you need to get the job done. Available with pressure lubricated pumps.

Compressor-Generators

Compressor-generators combine reliable compressed air and on-demand electrical power in one engine-driven package, making them ideal for remote and mobile job sites. Commonly used in construction, utilities, oil and gas, and service fleets, these units run air tools while simultaneously powering lights, pumps, and other equipment.

Compressor-Generator-Welder

The ultimate all-in-one solution for crews working where power is limited or nonexistent. Built for construction, oil and gas, utilities, and mobile service fleets, these machines deliver compressed air for heavy pneumatic tools, with onboard welding capability and auxiliary power from a single engine-driven unit.

Hydraulic

Hydraulic air compressors use a vehicle’s existing hydraulic power, making them ideal for service trucks and mobile applications with limited space and power. CAS hydraulic units are built with heavy-duty components, and are designed to be easy to install, use, and maintain. Available with reciprocating pumps or rotary screw airends.
