Pressure at the extruder head varies by application, but for free extrusion of plastic tubing, the internal air support pressure is typically ultra-low — ranging from below 1 inch of water up to 0-5 psi. MicroAir regulators are specifically designed to control these very low pressure ranges with high precision and stability, ensuring consistent tubing diameter and wall structure.
