Model

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

Diaphragm options:

For Pond Air 2 (2-Outlet Aerator) - Generation 2 (2012-present) item #75003 - 1 assembly cartridge.

For Pond Air 4 (4-Outlet Aerator) - Generation 2 (2012-present) item #75004 - 2 assembly cartridges.

Excellent

I had searched for replacement parts for my aerator and a couple of options came up. After looking at all I choose Pond and Garden Depot. Best prices, fast shipping. Excellent!!!!! Have already passed on your info to a friend with a pond. I have saved your link for future pond needs.

Easy to install - Pump worked like new!

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 - +++++
