MicroAir Regulator vs Generic Pressure Regulator

MicroAir II uses contact closure or manual control inputs and has a standard response time of approximately 2 minutes to full scale, making it ideal for stable diameter control applications. MicroAir IV accepts a 0-10V analog input for PLC connectivity and responds in under 0.1 second — enabling high-speed switching for demanding bump and taper tubing production.

MicroAir regulators cover ultra-low to low pressure ranges, from as little as 0–2 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 and 0–5 psi. Each unit can be configured for the specific range your extrusion process requires.

Yes. MicroAir IV models accept a 0–10 volt analog input, enabling direct integration with PLCs or other supervisory control devices. This makes them suitable for automated extrusion lines requiring programmable switching, bump and taper tubing production, or closed-loop diameter control from an external controller.

Single-channel models suit standard single-lumen tubing. Dual-channel units control two independent lumens simultaneously. The 3-channel and 4-channel MultiAir models are designed specifically for multi-lumen catheter and medical tubing, allowing each channel to have its own pressure range, digital display, and output — all within one stainless steel enclosure.

MicroAir regulators are built for long-term industrial use, with an expected lifespan of 10 to 20 years or more under normal operating conditions. They require no calibration, have low maintenance requirements, and are constructed in stainless steel enclosures — contributing to their durability and long service life in demanding extrusion environments.
