This is a repair kit for Whisper 20 & 40 Air Pumps.
The Whisper Air Pump is a unique dome shaped pump. The wide footprint, rubber feet and suspended motor all help to eliminate sound producing vibrations. Sound dampening chambers minimize turbulence while producing a smooth, almost silent stream of air. Powerful diaphragms allow sufficient airflow for even deepwater use.
The Whisper 20 & 40 Air Pumps are good for aquariums up to either 20 or 40 gallons in size (respectively).
