MicroAir Regulator for Multi-Lumen Tubing Extrusion

The number of channels required corresponds to the number of lumens in your tubing. OLC offers single, dual, 3-channel, and 4-channel MicroAir units. Each channel independently controls air pressure for one lumen, allowing different pressure ranges and display options per channel. For complex profiles, the 3-channel or 4-channel MultiAir units are most appropriate.

MicroAir regulators are available in pressure ranges from as low as 0–3 inches of water up to 0–5 psi. Extended ranges up to 0–30 inches of water are available on select models like the MultiAir 3-channel MicroAir I. All units operate from standard factory air regulated down to approximately 45–65 psi input.

MicroAir II models use contact closure inputs (Air Up / Air Down signals from a diameter gauge) and manual 30-turn knob control, with a standard response time of approximately 2 minutes. MicroAir IV models accept 0–10V analog input for PLC control with high-speed response of less than 0.1 second (typically 20 msec), making them ideal for bump and taper tubing applications.

Yes. MicroAir IV series units accept a 0–10V analog input, making them fully compatible with PLCs and external control devices. This enables automated, programmable pressure switching — essential for applications like bump and taper tubing where rapid, precise pressure changes are required during the extrusion run.

Yes. MicroAir regulators are widely used in medical tubing and catheter manufacturing, where dimensional accuracy is critical. Their ultra-low pressure capability, hysteresis-free operation, and ability to regulate below 1 inch of water make them ideal for tight-tolerance medical-grade tubing. All units are CE compliant, and many are Made in the U.S.A.

All MicroAir units include a 3-year warranty covering parts and labor, unlimited phone support, and access to technical documentation. A range change service is available for units needing pressure range modifications. OLC also offers a free range change within 30 days of purchase on select models, ensuring your regulator meets your exact application requirements.
