Product Description

The Easypro CAS Compact Aeration Systems are reliable continuous duty aeration systems for ponds and water gardens up to 3500 gallons. Featuring whisper quiet CMC series air compressors, these systems provide air circulation, elevate oxygen levels, and provide deicing. All while operating at volume above a whisper and using only pennies of electricity a day.

Each system comes with up to 4 diffusers depending upon model selected, making these aeration systems perfect for ponds with irregular shapes. The included check valves install inline and protect the pump from suffering water damage in case of power failure and the subsequent back pressure.
