Blue Diamond Enviro ET Series Air Pumps | 10 Models

The Blue Diamond Enviro ET Series Air Pumps are perfect water aerators for water gardens and ponds because they add oxygen and circulate water very efficiently. These linear diaphragm air pumps make the water clearer and healthier thereby benefiting fish, aquatic plants and aerobic beneficial bacteria. The robust construction of these air pumps provide reliability when used in the winter for keeping a hole in surface ice so toxic gas can escape. 

These pumps also can add oxygen to septic system wastewater to encourage aerobic bacteria to decompose organic matter. 

Easy to set up, each air pump includes brass fittings. They are exceptionally quiet, operating at a sound level as low as 35 decibels (depending on model) and use very little energy. These weatherproof, thermally protected pumps have specially formulated material for their diaphragm. These series of air pumps are constructed for longevity.

Models ET30 and ET40 come with a 3/8" ID brass fitting, while models ET60 and above each come with a 1/2" ID brass fitting.

Please Note: Models ET60A, ET80A, ET100A and ET120A include a built-in alarm that buzzes and displays an LED light warning signal when low pressure is detected in the airline.
