MicroAir Regulators

MicroAir Regulators series of Ultra Low Pressure Air Regulators and Controllers for Manufacturers of Extruded Tubing.

The MicroAir provides high precision control of tubing outside diameter by regulating air pressure to a set point during the manufacture and extrusion of medical, catheter, and automotive tubing. Our precision low pressure air regulators are used for precise air sizing and ovality of extruded plastic tubing. Internal air pressure is maintained for widely varying flow rates such as when a cut is made or variations in your process, etc. The “force balance regulator” also called “back pressure regulating valve” provides instantaneous response to changes in flow rate and maintains a set pressure with flow rates from near zero up to the rated maximum. Both our low-tension spring models and our high speed linear solid-state model offer some of the highest flow rates in the industry.
