Collection: Compressors - Rotary / Piston

Cast Air Rotary & Piston Air Compressors

Cast Air has been building air compressors in Spicer, Minnesota since 1991 — all cast iron construction, family-owned, made to run in real shops under real conditions. This collection covers both their piston and rotary screw lines so you can compare technologies and pick what actually fits your operation.

If your air demand is intermittent — tire work, spray painting, general shop tools with breaks in between — a Cast Air piston compressor is the straightforward choice. Lower upfront cost, simple to service, and cast iron cylinders that hold up to years of hard use. For operations running air continuously — production lines, fleet shops, body shops pulling 8-hour shifts — a Cast Air rotary screw compressor is built for that duty cycle. Quieter operation, consistent CFM delivery, and designed to run loaded without the heat buildup that kills reciprocating pumps in continuous-duty applications.

Not sure which technology fits your CFM requirements, tank sizing, or duty cycle? Call us at 866-217-0063. As an authorized Cast Air dealer, we can walk you through the specs and help you match the right unit to your shop — without the guesswork.
