3 PSI Pressure Regulator for Flow Control Systems

MicroAir pressure regulators have a 10-20 year operational lifespan and require no calibration throughout their service life. They maintain accuracy over decades of continuous operation, as evidenced by customers reporting reliable performance for over a decade without calibration issues.

These regulators provide precision pressure control with accuracies of +/- 0.1% full scale below 60" water, hysteresis-free operation, and high-speed response capabilities (typically 20 msec). This level of precision is essential for medical catheter and tubing extrusion requiring strict dimensional tolerances. Medical tubing manufacturers report that the instant response to air flow changes completely eliminates tubing wall inconsistencies.

Yes, multi-channel configurations are available including dual, 3-channel, and 4-channel systems for multi-lumen tubing applications. Each channel provides independent control with individual range settings, allowing you to manage complex profiles with varying pressure needs across different lumens simultaneously.

On Line Controls provides comprehensive repair service with upfront cost estimates and a three-year warranty on parts and labor. Customers report 24-hour turnaround times for diagnosis and repair, with unlimited phone support for technical assistance. Range change service is also available to adapt existing units to different pressure requirements.

Yes, the MicroAir IV series accepts 0-10V input signals for direct PLC integration and programmable high-speed switching. Models with contact closure input capability are also available for integration with automated control systems, offering three operational modes to suit different manufacturing setups.

High-speed models feature precision voice-coil linear motors that respond in less than 0.1 second (typically 20 msec) compared to standard response times of 2 minutes. This rapid adjustment capability is essential for bump and taper tubing production and enables manufacturers to handle complex profiles that require instantaneous pressure changes during the extrusion process.

Yes, these regulators are made in the USA with 44+ years of manufacturing excellence. They feature precision engineering with accuracies of +/- 0.1% full scale and are built for demanding manufacturing environments with proven reliability. The company maintains CE compliance for international applications.
