Norweco Hydro Kinetic Air Pump (A100) 
 
The air pump has been specifically designed for use in the Hydro-Kinetic treatment system and includes impact-resistant rubber diaphragms and valves to prolong air pump life. The unique design provides excellent cooling and quiet operation. The air pump can be remotely mounted or installed in the access riser above the aeration chamber. Fresh air enters the air pump through a filter located under the cover of the pump housing. The air is introduced below the liquid surface through a prefabricated diffuser assembly. Only the plastic diffuser assembly and the air piping are submerged.
