Pond Aeration » Air Diffusers » Air Stick Air Diffuser

This 12 inch 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.
