Eheim Air Pump Membrane Diaphragm 2pcs

Restore reliable airflow to your aquarium air pump with the Eheim Air Pump Membrane Diaphragm Set. These genuine Eheim replacement diaphragms are designed for compatible Eheim air 100, air 200 and air 400 air pumps.

Air pump diaphragms are wear components that can gradually lose flexibility, resulting in reduced airflow or inconsistent pump performance. Replacing worn diaphragms can help restore efficient air delivery and extend the service life of your Eheim air pump.

Eheim's spare-parts documentation lists the swing arm with membrane for the air 100, air 200 and air 400 series, with separate part numbers for 50Hz and 60Hz versions.
