AirCadence P3

Pneumatic control hits a sweet spot for K2–K3 walkers: more cadence response than friction, less weight and maintenance than hydraulics. The AirCadence P3 pairs an air cylinder with a stability-focused four-bar frame, so swing keeps pace with moderate speed changes while heel-strike security comes from geometry rather than wearer vigilance.

The pneumatic cylinder self-compensates for temperature and adjusts via independent flexion and extension needle valves; no fluid service is ever required. Mass is 720 g on a 7075 aluminum linkage with sealed bearings, flexion is 150 degrees, build height 145 mm, rating 125 kg.
