MicroAir Regulator vs Generic Pressure Regulator

MicroAir I uses a simple 30-turn manual knob for set-point adjustment with standard (~2 minute) response time. MicroAir II adds contact closure input compatibility for integration with diameter gauges or external controllers, also at standard response speed. MicroAir IV uses a precision voice-coil linear motor with 0-10V analog input for PLC control, delivering high-speed response under 0.1 second — ideal for bump and taper tubing applications.

MicroAir regulators are available in ultra-low and low pressure ranges, starting from 0-2 inches of water up to 0-5 psi. Specific ranges include 0-3", 0-5", 0-10", 0-15", and 0-30" of water, as well as 0-3 psi and 0-5 psi. Each unit is factory-calibrated to its selected range, and OLC offers a range change service for units already in the field.

Yes. MicroAir II models accept Air Up/Air Down contact closure inputs from diameter gauges or other controllers. MicroAir IV models accept a 0-10V analog input signal, enabling direct integration with PLCs or other automation devices. This allows closed-loop diameter control during the extrusion process, making it suitable for automated production lines.

Each lumen in a multi-lumen tube requires its own independently controlled air pressure channel. OLC offers dual-channel, 3-channel, and 4-channel MultiAir configurations. Each channel can be set to a different pressure range and can have its own digital display and output option, giving full independent control over every lumen in the extrusion process.

All MicroAir regulators include a THREE (3)-year warranty on parts and labor, along with unlimited phone support for the life of the product. Units ship worldwide via UPS, DHL, or FedEx from OLC's Shrewsbury, Massachusetts facility. A range change service is also available for units requiring a pressure range modification after purchase.

Generic pressure regulators are not designed for the ultra-low pressure ranges (below 1 inch of water) required in plastic tubing extrusion. MicroAir regulators feature hysteresis-free action, viscostatic damping, and precision voice-coil motors that maintain stable set-point pressure even with varying flow rates — capabilities that generic regulators cannot replicate. OLC units also have a 10-20+ year service life with minimal maintenance.
