MicroAir Regulator for IV Tubing Extrusion

MicroAir regulators are available in ultra-low pressure ranges starting from 0–2 inches of water up to 0–5 psi. Specific range options include 0–3 inches of water, 0–5 inches, 0–10 inches, 0–15 inches, 0–30 inches of water, and 0–3 or 0–5 psi, allowing selection based on exact extrusion process requirements.

MicroAir I uses a simple 30-turn manual knob for set-point adjustment. MicroAir II adds contact closure inputs for automatic control from a diameter gauge or controller, with manual override buttons. MicroAir IV offers high-speed 0–10V analog input for PLC integration and sub-0.1-second response time, suited for bump and taper tubing applications requiring programmable switching.

The number of channels should match the number of lumens in your tubing. OLC offers Single Channel, Dual Channel, 3-Channel (MultiAir), and 4-Channel (MultiAir) configurations. Each channel can be set to a different pressure range and can have its own display and output option, providing independent control over each lumen simultaneously.

Yes. MicroAir IV models accept a 0–10V analog input, enabling direct connection to a PLC or automated control device. MicroAir II models accept Air Up and Air Down contact closure signals from diameter gauges or external controllers, allowing closed-loop automatic diameter control during the extrusion process.

MicroAir IV delivers high-speed response of less than 0.1 second (typically 20 milliseconds) for a 50% full-scale step, making it ideal for bump and taper tubing. MicroAir I and II have a standard response time of approximately 2 minutes to full scale, which is suitable for stable steady-state medical and catheter tubing extrusion processes.

All MicroAir regulators include a 3-year warranty covering parts and labor, plus unlimited phone support for the life of the product. A range change service is available free of charge within 30 days of purchase. Technical documentation is also provided through the company's Services page and product manuals, and units ship worldwide via UPS, DHL, or FedEx.
