EasyPro Replacement Diaphragm Kit for CAS4

Genuine replacement diaphragms for EasyPro "Compact Aeration System" CAS 2 & CAS4 Aerators. These kits includes diaphragm assemblies and detailed instructions to return your air pump back to proper performance. Over time the air pressure and output will drop which typically requires replacement of the diaphragms. These are considered normal “wear” items and can be done on a regular basis (every 6 to 12 months) or once loss of output is observed. The CAS systems are incredibly economical, but EasyPro has made sure that they are quickly, easily, and affordably serviced so you can extend the service life for years rather than throw them out like many other economical options require. 

Diaphragm options:

CAS2 - CMC5RK - 2 Diaphragm Assemblies, Left & Right (2 Outlet)

CAS4 - CMC8RK - 2 Complete Diaphragm Assembly Cartridges (4 Outlet)
