The Active Vacuum Unit & Valves is a high-performance elevated vacuum prosthetic suspension system designed to ensure a secure, airtight interface between the liner and the socket. Engineered as an active vacuum pump for prosthetics, this unit utilizes the user’s natural gait to eliminate pistoning and maximize stump stability through continuous air discharge.

Free Rotation


Technical Highlights


  • Vacuum Power: Creates ~0.5 bar (15 in.Hg).

  • Stability: Grips stump firmly, no pistoning.

  • Comfort: Absorbs high ground reaction forces.

  • Adjustment: Free rotating air hose connector.

The Active Vacuum Unit functions by creating an elevated vacuum seal between the user’s liner and the socket, effectively eliminating pistoning movements and ensuring a firm grip on the stump. As the user walks, the unit compresses and releases, drawing air out through one-way valves. This continuous discharge creates a vacuum environment of approximately 15 in.Hg (0.5 bar) after multiple steps, significantly enhancing user comfort and connection security.

Performance Technology


Step-Activated Vacuum

Discharges air from the sealed socket environment with every step. The pump action is powered by the user’s normal walking gait, maintaining a consistent vacuum seal without external power.


Impact Absorption

Beyond vacuum, the unit acts as a shock absorber. It dampens high reaction forces from the ground, reducing stress on the residual limb and increasing overall walking comfort.
