The ET double series range of air pumps ensures that there is plenty of water movement in wastewater applications; this boosts oxygen levels in the water, allowing aerobic bacteria to decompose. The double series offer high flow from a small footprint, and offer a useful alternative to expensive and ineffective rotary vane and side-channel blowers.
