Ultra Low Pressure Regulator Supplier USA

MicroAir ultra low pressure regulators are available in ranges from 0–2 inches of water up to 0–5 psi, with ultra-low options including 0–3 inches of water. The 3-channel MicroAir I also supports extended ranges up to 0–30 inches of water and 0–3 psi, making it suitable for a wide variety of plastic tubing extrusion applications.

MicroAir regulators are available in three control configurations: manual 30-turn knob (MicroAir I), contact closure input from diameter gauges or controllers (MicroAir II), and 0–10V analog input compatible with PLCs or other automation devices (MicroAir IV). Each configuration is designed for specific levels of automation in tubing extrusion lines.

MicroAir IV series regulators achieve a response time of less than 0.1 second (typically 20 milliseconds) for a 50% full-scale pressure step. This high-speed response is enabled by a precision voice-coil linear motor with viscostatic damping and makes the MicroAir IV ideal for bump and taper tubing applications requiring rapid pressure switching.

OLC's MicroAir regulators are purpose-engineered for plastic tubing extrusion, serving medical tubing, catheter manufacturing, multi-lumen tubing production, automotive tubing, plastic profile extrusion, and micro-tube manufacturing. They are also trusted by OEM extruder manufacturers including Davis-Standard, Conair, and Gimac for integration into their extrusion lines.

MicroAir regulators are built for longevity, with an expected lifespan of 10 to 20 years under normal operating conditions. They require no calibration, have low maintenance requirements, and use damping fluid that does not contact the process air, contributing to their exceptional durability and reliability in continuous production environments.
