Active Vacuum
Shock Absorption
Prevents Pistoning
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.
