Ultramation OA-4 Pneumatic Linear Thruster with Pump 0-160 PSI WIKA Gauge

Ultramation OA-4 Pneumatic Linear Thruster with Pump 0-160 PSI WIKA Gauge

The Ultramation OA-4 is a self-contained benchtop pneumatic linear thruster combining an integrated electric air compressor pump with a guided linear actuation mechanism. The system generates compressed air onboard and routes it through an adjustable brass pressure regulator and inline bowl filter, delivering controlled pneumatic force to the thruster assembly over a working pressure range of 0–160 PSI. A WIKA pressure gauge mounted on the regulator block provides real-time pressure monitoring. This configuration — compressor, regulator, gauge, and linear thruster all in one compact unit — makes the OA-4 well suited for bench and fixture applications that require self-contained pneumatic linear motion without a separate compressed-air supply.

Applications

Pneumatic linear thrusters like the Ultramation OA-4 are used in laboratory automation, test fixture actuation, industrial process control, and precision assembly operations where repeatable linear force or displacement is needed. The self-contained pump design eliminates the need for a shop-air connection, making the unit portable and well suited for benchtop test stands, quality control fixtures, and research and development applications. Ultramation Inc. produced specialty pneumatic actuation equipment primarily for industrial and OEM automation customers. Units like the OA-4 are typically found in semiconductor handling, electronics assembly, and light-duty push/clamp automation where controlled, adjustable pneumatic stroke force is the requirement. The integrated regulator and WIKA gauge allow the operator to dial in working pressure precisely for each application.
