Whisper Air Pump (60) 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.
Not really as quiet as expected being it's called whisper but plenty of air flow.
very good product by karen from Hawaii07/13/2014
I run a fish hatchery where we use a large blower for aeration. In areas where we don't get air from the blower I use these whisper air pumps. The 60 is a good size for general use. We have five of them now with the oldest being about 6 years old and they work great.
