AIR DIFFUSER DISC 12" diameter (BHB-MD-310)
Matala Air Discs are 12 inch diameter and are designed for the wastewater treatment industry to very high standards. 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.
