PondAir 2 Diaphragms replace your worn or damaged diaphragms to restore air output and keep your PondAir 2 Aeration Kit running like new. Replacing the diaphragm yearly is recommended.
Over time the PondAir 2 compressor diaphragm can become worn. This will greatly reduce the air output of the unit. Replace the diaphragm every 6-12 months.
