During free extrusion, internal air pressure supports the tubing as it exits the die. By precisely regulating this ultra-low air pressure, the tubing's outside diameter and wall thickness are controlled. MicroAir regulators maintain a stable set-point pressure — even as flow rates vary — ensuring consistent dimensional accuracy throughout the extrusion run.
