Castair, Inc. has been a family-owned and operated manufacturer of air compressors since 1991. Our pumps are crafted from durable cast iron and are oil-lubricated, operating at slow RPMs for a quiet and long-lasting performance. We maintain a large stock of standard compressors and offer five distinct series: contractor, garage, commercial, industrial, and rotary screw. Our goal at Castair is to help customers understand the differences between our air compressors and those of our competitors, enabling them to make informed decisions about their air system needs.
