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 to capitalize on the sales and marketing prospects of the unique invention of an electronic air pressure regulator. 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 offers a large family of electronic air pressure regulators and air flow control valves that allow you to select the best product to match your exact application requirements. Whether you have specific package dimensions, housing requirements or an uncommon electrical interface, Proportion-Air has a product family to match your application.
WHERE OTHERS FEAR
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. This variety of outputs can be controlled by an equally diverse range of electrical inputs including analog, digital and serial communications. Our years of engineering and design experience gives us the confidence to take on the most problematic and exacting applications.
Proportion-Air handles these difficult requirements with unique advanced control technology, resulting in products with superior accuracy, resolution, and repeatability. This refinement of performance doesn’t mean they’re delicate. All Proportion-Air products are built tough to handle the most adverse environments. Proportion-Air’s advanced “dual loop” technology allows closed loop control using many different downstream sensors in order to control many different processes and applications.
Proportion-Air’s biggest asset has always been its people. Many companies offer some similar products, but you can’t get a straight answer when you call them. Proportion-Air not only offers superior products, but it has the people to back up those products. Our sole focus is electronic control of pressure and flow and this focus shows in our products. Call us, and find out for yourself.
