Product Description

The Blue Diamond Enviro ET Series Air Pump is perfect as an aerator for water gardens and ponds by adding oxygen and circulating water. This linear diaphragm air pump makes the water clearer and healthier thereby benefiting fish, aquatic plants and aerobic beneficial bacteria. The robust construction of the air pump  provides reliability when used in the winter for keeping a hole in surface ice so toxic gas can escape. 

This pump also can add oxygen to septic system wastewater to encourage aerobic bacteria to decompose organic matter. 

Easy to set up, the pump includes fittings. It is exceptionally quiet, operating at a sound level as low as 35 decibels and uses little energy. This weatherproof, thermally protected pump has specially formulated material for its diaphragm. The pump's construction is geared 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.

For applications requiring more than 33 ft. of tubing please contact us!
