This 12 inch air diffuser is great for smaller ponds. Use it with our Hakko 25L or use multiple units with the larger size air pumps. It is already self weighted. The air slots are 1mm long so the air bubble size is a little smaller for better O2 transfer. It can handle flow rates between 0.5 cfm to 2 cfm. The maximum rated flow is 3 cfm for short duration. It will add approx 12″ of water pressure to your system’s overall pressure.
The rubber membrane is wrapped around a hollow PVC tube. It is neutrally bouyant so 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. Rated flow for the 12 inch tube is 1 cfm to 4 cfm. The rated flow for the 24 inch tube is 2 cfm to 8 cfm. 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.
