Product Description

Genuine replacement diaphragms for Generation 2 Aquascape PondAir 2 and 4 Aerators. This line of air pumps is one of the most economical aeration systems on the market today. It is common for economy equipment not to have replaceable parts. However, this is not the case with the Aquascape PondAir 2 & 4 Aerators! 
Like most air compressors, prolonged use causes stress on the diaphragm and the pump may require some maintenance to keep its performance in peak condition and to prolong the aerator's life expectancy.

Diaphragm options:

PondAir 2 - Generation 2 (2012-present) item #75003 - 1 assembly cartridge

PondAir 4 - Generation 2 (2012-present) item #75004 - 2 assembly cartridge

    Was considering buying a new aerator - saw the replacement parts on the Pond and Garden Depot web site, and purchased the parts. Saved about 75% over a new unit. Easy to replace and the unit works like new - +++++
