Product Description
These air diffuser discs are replacements for the Matala Air Base Diffusers.
Our Matala Air Disc Diffusers are available in a 9-inch or 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. The 3/4" male thread makes it easy to attach to your feed line.
The 9-inch disc is capable of safely handling air flows of 25 lpm to 80 lpm.
The 12-inch disc is capable of safely handling air flows of 25 lpm to 160 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 3 years without trouble or maintenance.
Free shipping. Usually ships same or next day.
