    Want to keep your Airmax shallow water aerator working at it's best?

    Be sure to keep a set of these diaphragm replacement kits on hand so you can be up and running again in no time.

    The diaphragm is the air producing component of this system and it is considered a wearable part. Airmax suggests that the kits should be installed about every 1 to 2 years depending on the operational depth of the diffusers and other factors.

    If you see a drop in air output or the pump stops altogether, be sure to check the diaphragms for wear. Replacement is easy with a few simple tools and about 20 minutes of time.

    The LR25 kit will work for the Airmax SW20 (formerly the AM10SW) and the LR50 works for the Airmax SW40 (formerly the AM20SW)

    Note: It's suggested to replace the air filter whenever you replace the diaphragms in the airmax pumps. With that in mind we include free replacement air filters with every diaphragm kit.
