Long-Life Pressure Regulator for Continuous Extrusion Lines

OLC MicroAir regulators are engineered for a long life expectancy of 10 to 20 years under normal continuous extrusion operating conditions. This durability is achieved through the use of viscostatic damping fluid and precision mechanical components that require no ongoing calibration, significantly reducing total cost of ownership.

Yes. The MicroAir IV series (Single, Dual, 3-Channel, and 4-Channel) accepts a 0–10 volt analog input, making them fully compatible with PLCs and other automated controllers. They offer high-speed response of less than 0.1 second, enabling precise real-time pressure adjustments during automated extrusion sequences.

MicroAir I models feature manual-only control via a 30-turn precision adjustment knob. MicroAir II models add contact closure inputs (Air Up/Air Down) for integration with diameter gauges or external controllers. MicroAir IV models add high-speed 0–10V analog input for PLC integration and programmable switching, making them ideal for bump and taper tubing applications.

Yes. OLC MicroAir regulators are widely used in medical and catheter tubing extrusion, including multi-lumen tubing production. Their ability to regulate pressures below 1 inch of water with high accuracy makes them ideal for the tight dimensional tolerances required in medical-grade tubing manufacturing. All units are CE compliant for international shipping.

Single-channel units are suited for standard single-lumen tubing extrusion. Dual-channel units support two-lumen applications. The 3-channel and 4-channel MultiAir units are designed for multi-lumen tubing, allowing each lumen to be controlled independently at different pressure ranges, with separate displays and optional digital output per channel.

Yes. All OLC MicroAir pressure regulators ship worldwide via UPS, DHL, or FedEx from Shrewsbury, Massachusetts. Every unit includes a 3-year warranty on parts and labor, along with unlimited phone technical support. Units are CE compliant for international shipping, and OLC currently serves customers in 18 countries.
