Ultra low-pressure pressure regulator MicroAir II

for compressed airspringsingle-stage

Definition: AIR PRESSURE CONTROLLER "MicroAir" for tubing extrusion manufacturers. Auxiliary Equipment for Plastic tubing extrusion lines especially medical and catheter manufacturers that require precise stable air pressure put into the inlet in the die to control the ID inner diameter of the tube. Pressure Air Regulation and Control for tubing extrusion: The MicroAir II accepts Air Up and Air Down contact closure inputs from a Diameter Gauge, or other controllers on a plastic tubing extrusion line with up/down contact closures or logic outputs. Pressure is regulated by balancing against a low tension spring and by venting the surplus air. Two front panel buttons for manual control and the externally controlled inputs for auto control adjust the pressure set point by means of a small motor which adjusts the spring tension. The buttons are dual-speed. Indicators show Up, Down, and limit conditions. Zero to full Scale in approximately 2 minutes. Air Input: The air inlet is connected to normal factory air which has been regulated down to approximately 50 psi. Normal Output ranges are 0-3" of water, 0-5" of water, 0-15" of water, 0-30" of water, 0-3 psi and 0-5 psi. Meters are available in psi, inches of water, kilopascal and millibar.
