EasyPro Compact Aeration Series User manual

Your kit includes two diaphragm assemblies (right and left) 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.
