Expert Medical Device Converting Services & Manufacturing

On Line Controls, Inc. supports medical device manufacturing by supplying and servicing MicroAir ultra-low air pressure regulators used in medical tubing and catheter extrusion lines. These devices help control internal air support during free extrusion, improving outside diameter stability, production consistency, and long-term equipment reliability for manufacturers that require precise tubing dimensions.

MicroAir regulators provide stable, hysteresis-free ultra-low air pressure control inside extruded tubing. This helps manufacturers maintain consistent outside diameter while responding instantly to air flow changes. The technology is especially useful for medical tubing, catheter, and profile applications where tight tolerances, repeatability, and dependable operation are essential to efficient production.

The right model depends on the level of control required. MicroAir I is a manual model, MicroAir II uses up/down buttons and accepts contact closures, and MicroAir IV accepts 0–10 volt input for high-speed switching, bump and taper tubing, or PLC integration. Units are available in single through four-channel configurations.

Yes. MicroAir IV is designed for applications requiring high-speed switching, including bump and taper tubing. It accepts a 0–10 volt input and can connect with PLCs or other extrusion equipment. This makes it a practical option for manufacturers that need responsive pressure changes during complex medical tubing production.

MicroAir units less than 10 years old can usually be serviced in one day after they are received and tested. Older units may be sent in for evaluation. Units with serial numbers lower than 7000 are not repairable because their internal bodies have typically worn out after roughly 20 years of use.

MicroAir products are valued because they require no calibration and are designed for stable, low-maintenance operation. Manufacturers benefit from dependable pressure control without frequent adjustment routines. Proper installation, clean operation, and periodic service when needed help preserve performance over a long product lifespan, often reaching 10–20+ years.

All MicroAir units are covered by a three-year manufacturer’s warranty on parts and labor. Customers also receive unlimited phone support with purchase, including troubleshooting, installation guidance, maintenance advice, and assistance with model-specific questions. This support helps extrusion teams keep production lines stable and resolve pressure control issues efficiently.

Yes. On Line Controls, Inc. manufactures MicroAir units in the United States and ships worldwide using carriers such as UPS, DHL, and FedEx. The company serves customers across countries including the United States, Canada, Mexico, Germany, France, Japan, China, India, South Korea, and many others, with CE-compliant options for international shipping.
