Ultra Low Pressure Regulator Supplier USA

OLC MicroAir regulators cover pressure ranges from as low as 0–2 inches of water up to 0–5 psi. Specific range options include 0–3", 0–5", 0–10", 0–15", and 0–30" of water, as well as 0–3 psi and 0–5 psi, depending on the model selected.

MicroAir I features manual 30-turn knob control. MicroAir II adds contact closure inputs for integration with diameter gauges or external controllers. MicroAir IV uses a 0–10V analog input for high-speed PLC control and includes a precision voice-coil linear motor, enabling response times under 0.1 second — ideal for bump and taper tubing applications.

Single-channel units suit simple one-lumen tubing or profile extrusion. Dual-channel models handle two-lumen configurations. Three- and four-channel units are designed specifically for multi-lumen medical or catheter tubing, where each lumen requires independent, precisely controlled air pressure at a potentially different range.

MicroAir IV regulators respond in less than 0.1 second — typically around 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 is essential for bump and taper tubing production where rapid pressure switching is required.

Yes. MicroAir IV series regulators accept 0–10V analog input, making them directly compatible with PLCs and other automation controllers. MicroAir II models accept contact closure inputs from diameter gauges or external controllers. All models ship with dual selectable voltage input (110/220 VAC, 50/60 Hz) for global compatibility.

No calibration is required for any MicroAir regulator. The viscostatic damping fluid ensures stable, hysteresis-free operation without contacting the process air. Units are engineered for a service life of 10–20 years with minimal maintenance, and OLC offers a free range change service within 30 days of purchase.
