HISTORY

Proportion-Air, Inc. is an American manufacturer of electro-pneumatic pressure regulators and air flow control valves. Proportion-Air, Inc. was started in 1985 by owner Daniel E. Cook to capitalize on the sales and marketing prospects of the unique invention of an electronic air pressure regulator. This electronic air pressure control device was designed to accept a variety of electronic analog and digital signals in order to control pneumatic pressures with extreme accuracy while negating (and sometimes eliminating) the effects of vibration, mounting position or other environmental concerns.

 

WIDE VARIETY

Proportion-Air manufacturers a large family of electronic air pressure regulators and air flow control valves that allow you to implement the device that best meets your application requirments. Whether you have specific product dimensions and limited space, housing requirements or a unique and/or uncommon electrical interface, Proportion-Air has a product to match your application.

 

WHERE OTHERS FEAR

Proportion-Air designs and operates where others fear to tread, vacuum control, vacuum through positive pressure, absolute pressure, inches of water column, or direct 1:1 control up to l,000 psig. The variety of pressure outputs can be controlled by an equally diverse range of electrical inputs including analog, digital and serial communications. Our years of engineering, design and application experience enables us to have the confidence to take on the most problematic and exacting applications.

 

ADVANCED TECHNOLOGY

Proportion-Air excels with these difficult requirements by utilizing unique advanced control technology, resulting in products with superior accuracy, resolution, and repeatability. This refinement of performance does not mean they are delicate devices. All Proportion-Air products are designed and built tough to handle the most adverse industrial environments. Proportion-Air’s advanced “dual loop” technology allows closed-loop control with many different downstream sensors and transducers in order to control a broad range of different processes and applications.

 

AND PEOPLE

Proportion-Air’s biggest asset has always been its people. Many companies offer some similar products, but it is often difficult to 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 or shoot us an email, and find out for yourself.

 

Proportion-Air has become The Future of Control by setting the benchmark

in Advanced Pneumatic Control Technology
