Multi-Lumen Tubing Air Pressure Regulator

Pressure ranges span from ultra-low 0–3 inches of water up to 0–5 psi. Additional options include 0–5", 0–10", 0–15", and 0–30" of water, allowing manufacturers to match the regulator precisely to their specific tubing extrusion requirements.

Yes. In multi-channel systems, each channel can be independently configured with its own pressure range, digital display, and output options. This enables precise, lumen-specific control, which is critical for complex catheter and multi-lumen tubing designs.

These regulators are engineered for medical tubing manufacturing, catheter production, automotive tubing production, and plastic profile extrusion. They provide precise diameter control across all these sectors, with CE compliance supporting international use in markets including the USA, Germany, Japan, and China.

Three control options are available: manual control using 30-turn precision knobs, contact closure inputs that accept Air Up and Air Down signals from diameter gauges or other controllers, and 0–10V analog inputs for integration with PLCs or automated systems featuring programmable high-speed switching.

The systems deliver accuracy of ±0.1% to ±0.3% of full scale with hysteresis-free operation. They require no calibration, maintain constant pressure from zero to maximum flow rates, and use viscostatic damping to ensure stable, repeatable control during demanding extrusion runs.

All systems include a 3-year warranty on parts and labor, plus unlimited phone support. Products are manufactured in Shrewsbury, Massachusetts, and On Line Controls has been providing engineering expertise since 1980, with proven system lifespans of 10–20+ years.

Systems are available in single-channel, dual-channel, 3-channel, and 4-channel configurations. Upgrades from manual to automated control are supported — On Line Controls offers range change services and system upgrades.
