Vacuum volume management system that is slimmer, lighter, lower-clearance than Harmony P2 for lower limb amputees who want a precise socket fit for confident movement all day long.
 
Elevated vacuum reduces fluctuations in residual limb volume for precise fit throughout the day
20% lighter than Harmony P2 for better user acceptance
Lower clearance (4.6 inches/117 mm) so more users can benefit
Smaller circumference for better cosmesis
Less complex 3-in-1 functional ring allows service in the field
Functional ring absorbs vertical shocks and allows for natural rotation
Suitable for weights of 88 - 275 lbs
Recommended for activity levels K2 - K4
Scope of delivery:
  • 4R147 Harmony P3 Pump (incl. 4X147 Functional Ring*)
  • 2R57 Tube adapter, 34 mm, short, titanium
  • 2R117 Socket Connector (2x)
