Air Diffusers

Rubber Membrane Diffusers are considered to be one of the most economical and low maintenance air diffusers available. The rubber membrane has many small holes which expand as air fills the membrane. Medium size bubbles are released. The rubber membrane does not clog like air stones. Little or no maintenance is required. The Matala Rubber Membrane Diffusers are designed to be very low back pressure so you also get the best performance from your Hakko air pump.

The Matala Air Discs is available in a 9 inch diameter size. They were originally designed to very high standards for the wastewater treatment industry . The air pore size in the rubber membrane is designed to give a medium size bubble which will not put any significant back pressure on the system. In fact this special air disc only adds less than 6 inches of water depth back pressure. The 3/4" male thread makes it easy to attach to your feed line. The 9 inch disc is capable of handling air flows of 25 lpm to 100 lpm. The air disc is very low maintenance and in most cases NO maintenance. Simply wash the disc with clean water and bleach if it ever needs cleaning.  The air diffuser assembly features a hollow base that can be filled with sand or gravel. This eliminates the need for bricks and straps to get the diffuser to sink.

Aqualine has been using the diffuser disc assemblies  in our ponds for many years with very little maintenance required.
