This airlift is part of our under gravel filters. An airlift (riser tube) can be attached to each plate of the under gravel filter and can enhance the capacity of the under gravel filter by creating more water flow. With additional airlifts more water flows past the bacteria, improving the capacity to process waste materials.
The airlift is adjustable in length from 34 to 52 centimeters. If you saw the pipe you always can shorten it to the desired length. The diameter of the pipe is 2.05 centimeters inside, 2.3 centimeters outside.
Including internal air hose and air stone.
