Whisper Air Pump (40) The New Shape of Silence. Designed from the ground up for silence and performance.
Minimal noise, maximum air flow. The Whisper Air Pump's dome shape actually flattens sound wave frequencies. In addition, each model features sound-dampening chanbers designed specifically for that model. And the air pump's rubber feet and suspended motor prevent sound waves from reflecting off surfaces such as tables and shelves. Available in models for tanks from 5 to 100 gallons, Whisper Air Pumps provide powerful flow of air.
