MicroAir Controls
MicroAir ultra-low air pressure regulators support precise internal air control for extruded plastic tubing, including medical, catheter, straw, and automotive tubing applications requiring stable OD control.
Modernize extrusion lines and legacy control systems with industrial automation retrofit solutions from On Line Controls, Inc. Since 1980, manufacturers have relied on OLC for precise MicroAir pressure regulation, motorized potentiometer upgrades, repair support, and long-lasting components that improve tubing consistency, reduce maintenance, and extend the useful life of existing production equipment.
Precision retrofit components and support for extrusion manufacturers upgrading pressure control and automated motion systems.
MicroAir ultra-low air pressure regulators support precise internal air control for extruded plastic tubing, including medical, catheter, straw, and automotive tubing applications requiring stable OD control.
OLC supplies AC and DC motorized potentiometers for retrofit applications, with multiple RPM, voltage, resistance, turn-count, and gang configurations for legacy and modern automated control systems.
MicroAir units and OLC-built motorized potentiometers can be evaluated, repaired, or rebuilt when parts are available, helping manufacturers extend equipment life and reduce unnecessary replacement costs.

President
Kay DeWolfe serves as both owner and President of On Line Controls, Inc., bringing over 35 years of invaluable experience to the industrial pressure control industry. Under her leadership, the company has maintained its position as the recognized industry leader in ultra-low air pressure regulators for plastic tubing extrusion. Kay's extensive background in precision manufacturing and customer support has been instrumental in expanding OLC's global reach to serve customers across 18 countries while maintaining the highest quality standards. Her commitment to engineering excellence and customer satisfaction continues to drive the company's innovation in pressure control technology, ensuring that OLC's MicroAir and motorized potentiometer products remain the industry standard for precision and reliability.
Retrofit automation upgrades existing manufacturing equipment with newer control components, sensors, regulators, or interfaces instead of replacing the entire production line. For extrusion manufacturers, this can include adding precise pressure regulation, replacing legacy motorized potentiometers, or improving PLC-compatible control. The goal is better consistency, reliability, and equipment life while preserving proven machinery.
