Matala Air Discs are 9 inch 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 40 lpm to 120 lpm. <br> <br> 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. <br>We have some of these air discs in systems now for over 3 years without trouble or maintenance.
