Our Air Tube Diffusers are designed to be a drop in system. The rubber membrane is wrapped around a hollow PVC tube. It is negatively bouyant but you may also add small stones to the inner tube to increase weight so it stays put on the bottom of your pond or lake. The air holes in our tubes are a little larger than other brands so you get a medium size bubble which does not clog and puts very little back pressure on your system. This gives you a very low maintenance and effective aeration system.
To clean, simply wipe with a rag and clean water occasionally.
Our Matala Air Discs are 9 inch diameter and are designed for the wastewater treatment industry to very high standards. The air por 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 40lpm to 120 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 with out trouble or maintenance.
