Hakko Air Pumps » Air Stones & Diffusers » Matala Air Disc

Our Matala Air Discs are available in two sizes. 9 inch diameter and 12 inch diameter. They 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 handling air flows of 25 lpm to 100 lpm.

The 12 inch disc is capable of handling air flows up to 180 lpm.

Both discs are very low maintenance and in most 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 6 years with out trouble or maintenance.

This is the best diffuser choice for all Hakko air pumps.  You may want to buy the air base to help keep the air disc positioned on the bottom of pond.
