Electronic Pressure Control Product Applications

Pneumatic Applications is our specialty 

The Proportion-Air approach to business has always been application-driven. We strive to meet the customers’ needs where they are – applying our product so it matches your specific requirements. We don’t build products and then put them on a shelf, hoping they will be used “as is.” Rather, every solution is a custom fit. We’ve helped solve thousands of applications.

We take our basic product and gather application information from you, then tailor a solution to meet your application needs.

Seven Basic Applications

Electronic Pressure Control Product ApplicationsThese are the basic applications to which we customize our products.


These terms may sound rather industrial, but they are actually universal in nature. Such applications are suitable across the board from industrial, to testing, to medical.

We are not limited in the scope of assistance. Where ever there’s a need for tight control using one of those seven applications, Proportion-Air can design your solution.

Size is Not an Issue

It doesn’t matter the size of the volume which needs pressure control. Our products look deceptively small – people may be tempted to think, “It’s so small. How could you pressurize a room and keep up with all the leaks you might encounter?” But we do.

Large Applications

For example, we’ve provided application solutions to aircraft manufacturers who wanted to fatigue test the fuselage of their aircraft. They needed a tool that could pressurize the large cavity at an altitude of 50,000 feet, and then reduce the pressure to sea level – and do that as many times a day as possible. Pressurizing a large volume is easy, but venting it back is not. Using our own base product and adding components from elsewhere, Proportion-Air came up with a spot-on solution.

Small Applications

A medical client came to us wanting to control flow for a blood gas analyzer. Their device pushes blood through a sensor which records the number of tiny red and white blood cells, and they needed to control that minute, precise flow. We met the application challenge by designing a high resolution, low pressure product that put pressure on top of the blood so it could control the speed with which the blood cells went past the counter.

High Pressure and Low Pressure

We offer the same range of applications for high and low pressure needs. We have designed products which regulate water pressure in water jet cutters so they can work at 10,000 psi – that is, they can cut steel.  Likewise we also have applications where we need to regulate vacuum, which we do better than anyone else in the business.

An Impressive Scope

We run the gamut for industry application. When you use a Proportion-Air product, you’re getting the expertise of an entire engineering department – people with years of experience in a wide range of industries who know what to ask and know how to apply it.

It doesn’t matter how big or small, how low or high the pressure for your application. We’ll gather the information necessary to understand all nuances of an application – then we’ll guide you to the correct solution.

  • I'm happy to report that the trial on the QPV1 has been going well. I'm quite impressed by the performance of the unit. I'm also very impressed by the service that I received from Nick Archer which I think merits specific attention. Nick has been extremely responsive to my emails and questions. He has been patient, has kept his word, and has always replied to me quickly with an answer or a reply to my questions. Nick has provided me with what I, and certainly others in my group, consider to be a perfect example of top notch high quality customer service.
