The ETA 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. When used in medical applications, the ETA series provides a high low at low pressure. Enviro ETA pumps come with a built in alarm which detects low pressure in the airline.
