Note from the Manufacturer:

Did You Know...

Did you know that the maximum depth the 2-stick self-weighted KoiAir™1 and KoiAir™2 diffusers should be placed is 4' and 5' respectively? Adhering to these depth parameters will insure that you get the longest life out of your aerator's diaphragm. 

Regular Maintenance:

Diaphragm Maintenance

Your KoiAir™ compressor will need a maintenance kit (KoiAir™ 1- Item #510145, KoiAir™2 - Item #510146) every 12–36 months depending on: operating depth, air quality and operating temperature. If your compressor is operating but there is no air coming out of the diffusers, you will generally find that it is time to replace your diaphragm.

Membrane Stick Maintenance

No maintenance required. Replace membrane sticks (#510165) if visibly damaged or if system has poor performance.

Air Filter Cleaning

Unscrew the cover on the back of the compressor to expose the air filter. Remove the air filter and brush away any dust particles. Air filter should be replaced every 6 months. (KoiAir™ 1- #510153, KoiAir™ 2- #510149)
