Frequently Asked Questions

What is a 3-stage regulator?

A 3-stage regulator refers to a pressure regulation system that processes and reduces pressure across three distinct stages for increasingly fine control. In the context of ultra-low pressure flow control systems like the MicroAir series, regulators are engineered to deliver precise output pressures — ranging from as low as 0-3" water column up to 0-5 PSI — ensuring highly stable, hysteresis-free pressure delivery suited for demanding applications like medical tubing and plastic profile extrusion.
