Profile Extrusion Air Pressure Control — Precision Regulators

The MicroAir regulator line covers a wide range of ultra-low pressures, from 0–3 inches of water column up to 0–5 psi. Intermediate ranges including 0–5, 0–10, 0–15, and 0–30 inches of water are also available, allowing each channel to be configured to match specific tubing or catheter manufacturing requirements.

The pressure profile refers to the air pressure distribution used to internally support and control the diameter of extruded tubing. Our MicroAir regulators maintain precise pressure profiles from 0–3 inches of water to 0–5 psi with hysteresis-free control.

Yes. The MicroAir IV series accepts 0–10 volt analog input signals for seamless integration with PLCs and automated control systems. This enables programmable pressure profiles, high-speed automated switching, and closed-loop diameter control for advanced manufacturing processes.

On Line Controls offers single, dual, 3-channel, and 4-channel configurations across the MicroAir product line. Each channel operates independently, allowing different pressure ranges and individual control settings — making them ideal for multi-lumen medical tubing and catheter extrusion where each lumen requires its own precise pressure.

The MicroAir IV series delivers typical response times of 20 milliseconds, well within the under-0.1-second threshold required for high-speed bump and taper tubing applications. This rapid response is achieved through a voice-coil linear motor with viscostatic damping.

The MicroAir regulator line is engineered for medical device manufacturing (including catheter and medical tubing extrusion), automotive component production (fuel lines and fluid transfer tubes), industrial plastics extrusion (including bump and taper profiles), and micro-tube manufacturing that requires ultra-precise pressure regulation below 1 inch of water.

MicroAir regulators are engineered for 10–20+ year lifespans with minimal maintenance requirements. Their sealed design with viscostatic damping ensures stable operation without ongoing calibration. All units are made in the USA and backed by a comprehensive 3-year warranty covering parts and labor.
