Our Complete Line of Electronic Air Pressure Regulators

Proportion-Air’s core focus is offering a complete line of electronic air pressure regulators. It seems like every pneumatic control valve company offers a line of electronic pressure regulators these days. EPR’s (Electronic Pressure Regulators) are an auxiliary product to these companies.  Some of them even offer advanced features or low cost.

As long as the electronic pressure regulator offered in their catalog matches what you want, you might be well served buying an EPR from a company which offers many types of pneumatic products.  But you’ll need to get your checkbook and your calendar out if you’d like an electronic pressure regulator that is anything outside of a catalog 0-100 psig plain vanilla model.


Proportion-Air focuses on your needs and builds a regulator to match them. We back up our pressure regulators with experienced people who actually answer the phone when you call.

Heaven help you if you need a technical question answered by many of our competitors who make EPRs or worse yet, immediate focus on you as a customer if you have a machine go down. At Proportion-Air, we only build electronic air pressure regulators and air flow controls.

Our competitors build thousands of products, one of which is an electronic pressure regulator. We build only electronic pressure regulators, but we customize them in thousands of ways.
