MAII       Motorized PotentiometerMAC2WCMC20A
Ultra Low Air Pressure Regulator and Controllers for
Tubing Extrusion
Potentiometers or Rheostats
MicroAir units provide ultra low pressure air regulation and control for precise air sizing of extruded plastic tubing and catheters. By regulating air pressure to a set point during the manufacture and extrusion of tubing, our MicroAirs control the outside diameter to maintain your critical medical, catheter and automotive tubing dimensions.
