Airmax PondAir 4 Replacement Diaphragm

PondAir 4 Diaphragms replace your worn or damaged diaphragms to restore air output and keep your PondAir 4 Aeration Kit running like new. Replacing the diaphragm yearly is recommended.

Over time the PondAir 4 compressor diaphragm can become worn. This will greatly reduce the air output of the unit. Replace the diaphragm every 6-12 months.
