Pro-Air Mizer | Compressor Header Pressure Flow Controller
Typically compressed air goes to a header, or storage tank where it builds up pressure (capacitance) to distribute as needed. The build-up is necessary so the compressor doesn’t have to work constantly. Without the extra storage, it would be impossible to keep up with demand. Pro-Air Mizer controls header pressure and helps deliver stable and consistent pressure to all drops.Read More About the Pro Air Mizer

What an excellent process you have for specifying parts for your customers. I am very impressed.
I met with Bill today...He was impressed by your knowledge and application of your products and wanted me to thank you for your excellent support.
It is really a pleasure to work with Proportion-Air. You cannot imagine what kind of problems I have with some manufacturers. Thank you very much!
I'm astonished for the quickest answer ever!
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.
