CrystalClear® KoiAir™ Diaphragm Compressor Maintenance Kits - KA20

The KoiAir KA Series Diaphragm Compressor Maintenance Kits contain all the parts you need to restore your KoiAir Aeration Kit to its maximum performance. Over time the diaphragms in the KA Series Aeration Compressors can become worn. This will greatly reduce the amount of air going into your pond.

KA20 Diaphragm Compressor Maintenance Kit fits the KA20 Compressor or KoiAir Mini and KoiAir 1 Aeration Kits. KA40 Diaphragm Compressor Maintenance Kit fits the KA40 Compressor or KoiAir 2 Aeration Kit.

We recommend replacing the diaphragms every 12 to 36 months.
