Tetra Whisper 100 Air Pump (New Design Ul Approved)

Pumps are 115V 60Hz and UL-approved for both fresh and marine water. Minimal noise, maximum air flow. The Whisper? 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. Royal Item Number: ATS77850
