MicroAir Regulator for IV Tubing Extrusion

MicroAir regulators are available in a wide range of ultra-low pressure outputs, 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. Range change service is available and can be provided free of charge within 30 days of purchase.

MicroAir I models feature manual control via a 30-turn precision adjustment knob. MicroAir II models add contact closure inputs, allowing automatic adjustment from a diameter gauge or PLC. MicroAir IV models use a high-speed precision voice-coil linear motor with 0-10V analog input, enabling sub-0.1-second response times ideal for bump and taper tubing applications.

Yes. MicroAir IV models accept a 0–10V analog input, making them fully compatible with PLCs and other automated control devices, including inline diameter gauges. MicroAir II models accept contact closure (Air Up / Air Down) signals from diameter gauges or controllers, enabling closed-loop automatic outside diameter control during extrusion.

Each lumen in a multi-lumen tube requires independent pressure control. On Line Controls offers dual-channel (2 lumens), 3-channel, and 4-channel MicroAir systems. Each channel can be configured with a different pressure range and its own display, ensuring precise, independent air pressure control for every lumen in your tubing structure.

Yes. MicroAir regulators are widely used in medical tubing and catheter manufacturing environments. Their hysteresis-free, ultra-precise pressure regulation ensures tight dimensional tolerances required for medical-grade tubing. All units are CE compliant and manufactured in the USA, supporting quality system requirements for medical device production environments.

MicroAir regulators are built for long-term industrial use, with a typical lifespan of 10 to 20 years. All units include a 3-year warranty covering parts and labor, along with unlimited phone support from the manufacturer. The stainless steel enclosure and viscostatic damping design require minimal maintenance over the product's operating life.
