selling a very nice pond air supply pump that can deliver more than 65 liters of clean air to a pond or other water body supplying much needed oxygen to fish and other animals. This pond air pump has a very long maintainance free life and the only thing that needs checking is a filter that is on top of the unit that can be accsessed by removing a knob on top of the unit. This filter can be washed and dried before it is placed back in the unit or a new one can be put in its place minimizing down time. This pump produces enough pressure to have deep air stones or diffusers in any aquatic setting. can have multiple supply outlets as well. The pump is very quiet when in opertion.
