Compair Air Compressors

Compair air compressors include these types of air compressors:

  - Variable speed rotary screw compressors
  - Oil-free rotary screw compressors
  - Fixed speed rotary screw compressors
  - Rotary vane compressors
  - Reciprocating air compressors

The brand Compair is global, and has been in the compressed air, ancillary equipment for compressed air systems, and other industries - with a broad range of products - for 200 years.

In 2008 Compair itself was assimilated. They are now part of the Gardner-Denver group, making, perhaps, more difficult an already complex web of product information and support. It must have been a real challenge for them to keep things going as the integration of mammoth companies like Compair and Gardner Denver would be herculean in the details that would have to be attended to.

Some of the product brands assimilated by them over the years include:

  • Le Roi
  • Holman
  • BroomWade
  • Cyclon
  • Dresser
  • Hydrovane
  • Kellogg
  • Reavell
  • Luchard
  • Mahle
  • Mako
  • DeMag
