Matala/Hakko Rubber EPDM Membrane 12" Air Diffuser-aerator-replacement disc-pond

Description

One Matala Round Membrane Air Diffuser (12" diameter)
for Pond or Lake Aerators
This Matala 12" membrane diffuser (AD12) is a great alternative to airstones in many aeration applications.
It contains hundreds of "I" slots that open as air pressure builds inside of the diffuser- providing uniform bubble distribution.
Diffuser has a 3/4" male thread inlet.
Very low maintenance; easy to clean.
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 25 lpm to 150 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.
