The Enviro ET250 A air pump helps to increase the amount of oxygen in the water. Providing a clean oil free air source it is exceptionally quiet in operation, as low as 35dB even when running continuously. With a built-in alarm, the ET250 A detects low pressure in the airline with an integral high sounding buzzer and bright LED warning signals. The ET250 A is easy to service with a competitively priced service kit and is also supported by our two-year warranty.
