Proportion-Air Logo

Proportion-Air, Inc. is a manufacturer of electronic air pressure regulators and air flow control valves. Proportion-Air, Inc. was founded in 1985 by corporate President Daniel E. Cook. This air pressure device was designed to accept a variety of electronic analog and digital signals in order to control pneumatic pressures with extreme accuracy while negating the effects of vibration, mounting position or environmental concerns.

Proportion-Air goes where others fear to tread, vacuum control, vacuum through positive pressure, absolute pressure, inches of water column, or direct control up to l000psi. Proportion-Air handles these difficult requirements with unique advanced control technology, resulting in products with superior accuracy, resolution, and repeatability. All Proportion-Air products are built tough to handle the most adverse environments.
