Air Pressure Regulator for Small Diameter Tubing Extrusion

MicroAir I models use manual control via a 30-turn fine adjustment knob with a standard response time of approximately 2 minutes to full scale. MicroAir IV models accept a 0–10V analog input for PLC or automated control and feature high-speed response of less than 0.1 second, ideal for bump and taper tubing applications.

Yes. OLC offers 3-channel and 4-channel MicroAir units specifically designed for multi-lumen tubing. Each channel can be configured to a different pressure range and can include its own digital display and output option, providing independent control over each lumen during the extrusion process.

MicroAir regulators support multiple control interfaces depending on the model: manual control via a 30-turn knob, contact closure inputs from diameter gauges or OD controllers, and 0–10V analog input for PLC or automated device connection. This flexibility allows integration into both manual and fully automated extrusion lines.

MicroAir IV models achieve accuracy of +/– 0.1% of full scale for ranges below 60 inches of water and +/– 0.3% for ranges above 3 psi. MicroAir II models provide better than 0.1 inch of water resolution with a digital display, ensuring highly precise diameter control throughout the extrusion process.

MicroAir regulators are used in medical tubing extrusion, catheter manufacturing, automotive tubing production, multi-lumen tubing, bump and taper tubing, plastic profile extrusion, micro-tube manufacturing, and plastic straw extrusion. They serve manufacturers across 18 countries worldwide, including the USA, Germany, Japan, China, and India.

No calibration is required for MicroAir regulators. They are designed for low maintenance operation with a long service life of 10–20+ years. The viscostatic damping fluid ensures stable, hysteresis-free operation without contacting the process air, significantly reducing wear and maintenance needs over the product's lifetime.
