Matala 12" Round Rubber Air Diffuser-Pond/Lake Aerator Supplies-Replacement disc

Matala Air Discs are 12 inches in diameter and are designed for the pond and 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. The 3/4" male thread makes it easy to attach to your feed line. Capable of handling air flows of 0.88 to 5.30 CFM. 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 3 years without trouble or maintenance.
