Now available from Afscan is the PUM, Purus Universal Membrane, a new revolutionary membrane that stops bad air coming up through the drainage system.
The new technique saves space without reducing the flow capacity and also functions as an air admittance valve when there is a negative pressure in the drainage system (secondary air ventilation). This enables better flow in the drainage pipe. To a certain extent, PUM also works as a back flow stop.
PUM Outlet application Bath, is one of Purus’ new outlet applications with the revolutionary universal membrane.
