MicroAir Replacement Regulator for Existing Extrusion Lines

No, pressure regulators are not universal. MicroAir regulators are purpose-built for ultra-low pressure applications in plastic tubing extrusion, with pressure ranges from 0–3 inches of water to 0–5 psi. Standard industrial regulators cannot achieve this level of precision. Always confirm pressure range, channel count, control interface, and mounting requirements before selecting a replacement unit.

In many cases, yes. MicroAir regulators use standard 1/4" NPT fittings and are designed to retrofit into existing extrusion line setups. However, compatibility depends on pressure range, channel configuration, and control interface. Contact OLC's support team with your current unit's specifications for a direct compatibility assessment.

MicroAir replacement regulators are available in pressure ranges from 0–3 inches of water up to 0–5 psi, including 0–5, 0–10, 0–15, and 0–30 inches of water, and 0–3 psi. Range Change Kits are also available if your process requirements change after purchase.

MicroAir I and II series regulators deliver a standard response of approximately 2 minutes to full scale, suitable for most steady-state extrusion processes. MicroAir IV series units feature high-speed response of less than 0.1 second (typically 20 ms), making them ideal for bump and taper tubing or PLC-controlled lines.

No. MicroAir regulators require no calibration. They maintain accurate, stable pressure output through a hysteresis-free regulating mechanism with viscostatic damping fluid. This contributes to their long service life of 10–25 years and minimizes maintenance downtime on extrusion lines.

All MicroAir replacement regulators include a 3-year warranty on parts and labor, along with unlimited phone support from On Line Controls' technical team. A Range Change Kit or service is also available for customers who need to modify their pressure range after installation.
