The diffusers require an air blower or compressor to drive the system. The air pressure required depends upon the depth of the water, in most situations the blower should be sized to give up to 1 bar air pressure with water depths up to 5 m. The compressor should be located adjacent to the air diffusers. However you could locate the compressor many 1000`s of meters from the diffusers if the pipe work is sized accordingly. The pipe work should be in metal, if plastic pipe is used, then the first 6 meters of pipe work should be metal in order to bring the air temperature down to at least 90 °C in the plastic pipe.
We are currently offering the 70008 version, which is 3 meters or 10 feet long (part number DAD3). Please call for further inquiries or air diffuser lengths.
