  • If you need a new air pump for your aerobic septic system, the Blue Diamond ET120A might be the ideal pump for you. Here are a couple of reasons why you should consider the Blue Diamond ET120A Septic Air Pump when you are looking to replace the 120 liters per minute pump for your ATU. These specific pumps are not to be used on ponds over 5 foot in depth as the back pressure will ruin them, as it is not good for them. Blue Diamond aerators noise level is higher than other comparable linear diaphragm aerators.


    In addition to its strong performance, the Blue Diamond ET120A Septic Pump is durable and built to last, making it a cost effective aerator. This weatherproof aerator incorporates Blue Diamond’s specially formulated diaphragm material to increase the life of the product, meaning less air pump replacements. The Blue Diamond ET120A also has reasonably priced repair kits to help you extend the life of your aerator. Your air pump can be costly to replace, so the durability of this pump will save you hundreds of dollars over time.

    Pump Alarm

    If an issue does arise with your air pump, the Blue Diamond ET120A has a built-in alarm to help you recognize and solve problems before they become expensive or cause costly damage to your aerobic septic system. The alarm detects low pressure in the airline and signals the problem with a high sounding buzzer and LED lights. This alarm alerts you to issues with the aerator before they become problematic.


    The Blue Diamond ET120A will help you conserve energy and help the environment. Blue Diamond utilizes green drive technology to help make this oil-free aerator one of the more energy-efficient models available for residential use. With power consumption as little as 125 watts, you can feel comfortable using this aerator intermittently or continuously. The Blue Diamond ET120A also helps the environment by destroying wastewater and releasing clear drainage instead of effluent into drainage fields.
