Multi-lumen tubing air pressure regulators deliver independent, ultra-precise air pressure control for each lumen during plastic tubing extrusion. These systems offer manual, automated, and high-speed programmable control with response times under 0.1 seconds. Featuring hysteresis-free operation, stainless steel construction, and pressure ranges from 0-3 inches of water to 0-5 psi, they ensure consistent diameter control across medical, catheter, and automotive tubing production.
