Overview
Benefits
The Harmony P4 HD (Heavy Duty) Modular is rated for patients up to 330 lbs and is a line extension to our mechanical vacuum pumps whose design allows for different proximal connections with the same fast vacuum generation as the other P4 pumps. The Harmony P4 pumps also incorporate a vertical shock reducing pylon and torsion unit in addition to active vacuum volume management. The modular design with external tubing allows for easy upgrade from older pumps or into existing vacuum sockets.
