Wear parts have to be replaced regularly. In case of normal wear the lifetime of the
diaphragms and valves is > 10000 operating hours. Bearings have a typical durability
of 40000 h. Motor capacitors have a typical durability in the range of 10000 to 40000 h de-
pending strongly on the operation conditions like ambient temperature, humidity or load.
• Check every capacitor regularly by measuring its capacity and estimating its op-
