The Tetra Air Pump, 10-30 Gallons, was formerly known as the Whisper 20. It features minimal noise & maximum air flow. The Tetra Air Pump’s dome shape actually flattens sound wave frequencies. In addition, each model features sound dampening chambers 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. This new version comes with a check valve.
