Our Matala Air Discs are designed for the wastewater treatment industry to very high standards. The air por 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" disc is capable of handling air flows of 40 lpm to 120 lpm the 12" disc is capable of handling 60 lpm to 180 lpm. The disc is very low maintenance and in some cases NO maintenance. Simply wash the disc with clean water and bleach if it ever needs cleaning. We have some of these air discs in systems now for over 4 years with out trouble or maintenance.
