Hakko Air Pumps » Air Stones & Diffusers

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.

These Air Tube Diffusers are manufactured in the USA. They are designed to be a drop in system. The rubber membrane is wrapped around a hollow PVC tube. The air slots in our tubes are a little larger than other brands at 2mm long each. You get a medium size bubble which does not clog and puts very little back pressure on your system.  The maximum flow is 7 cfm and 14 cfm respectively, for short duration. These tubes are commonly used in waste water treatment systems. Both size tubes only add an additional 12 inches of water pressure to your overall system pressure. This gives you a very low maintenance and effective aeration system.

You must add small stones to the inner tube to increase the weight so it stays put on the bottom of your pond or lake. A plug is included to keep the stones in.

The inlet connector is a 3/4" male pipe thread. We offer a 3/4"fpt x 5/8" barb connector so you can connect to our 5/8" sinking air hose.

To clean the rubber membrane, simply wipe with a rag and clean water occasionally.

USE A SINGLE 12 INCH DIFFUSER FOR HAKKO 40 OR 60 AIR PUMPS. Rated flow for the 12 inch tube is 1 cfm to 4 cfm.

USE A SINGLE 24 INCH DIFFUSER FOR THE HAKKO 80 TO HAKKO 120 AIR PUMPS. The rated flow for the 24 inch tube is 2 cfm to 8 cfm.

MULTIPLE 12 INCH DIFFUSERS CAN BE MANIFOLDED TOGETHER FOR THE HAKKO 80 TO 120.
