MicroAir Regulator for Automotive Tubing Extrusion

MicroAir regulators cover pressure ranges from as low as 0–3 inches of water up to 0–5 psi. Some models, like the MultiAir 3-channel MicroAir I, extend up to 0–30 inches of water. This flexibility accommodates the precise, ultra-low pressures required in automotive tubing extrusion.

OLC offers single-channel, dual-channel, 3-channel (MultiAir), and 4-channel (MultiAir) MicroAir regulators. Multi-channel units are ideal for automotive tubing with multiple lumens or when controlling several extrusion lines from a single enclosure, with each channel independently configurable.

MicroAir I uses a simple 30-turn manual knob for set-point control. MicroAir II adds contact closure inputs (Air Up / Air Down) from a diameter gauge or external controller for automated adjustment. MicroAir IV uses a 0–10V analog input for high-speed PLC-driven control with response times under 0.1 second.

Yes. The MicroAir IV series accepts 0–10V analog inputs, enabling direct integration with PLCs, diameter gauges, or other automation controllers. The MicroAir II series accepts contact closure inputs. This allows fully automated closed-loop diameter control during automotive tubing extrusion.

MicroAir regulators are built for a 10–20 year lifespan with minimal maintenance. No calibration is required. The viscostatic damping fluid used in the mechanism does not contact process air, ensuring long-term stability. All units are backed by a 3-year warranty on parts and labor.

Yes. All MicroAir regulators are CE compliant and ship worldwide via UPS, DHL, or FedEx. On Line Controls serves customers in over 18 countries, including Germany, France, Japan, China, and Mexico, making them a reliable global partner for automotive tubing manufacturers.
