Sweetwater® Generation II Diffusers PART #: ASI-3 to ASI-30

Perfect for custom manufacturing

Sweetwater diffusers manufactured by Pentair AES quickly became and still remain the standard of the aquaculture industry for diffused air aeration. The Generation II series is the same glass-bonded diffuser that is so resistant to clogging. Generation II diffusers give the added flexibility of changing the air diffuser fittings in the field. All diffusers have 1/8" FNPT threads that accept MNPT fittings, either straight or elbows.

Use tubing with a smaller I.D. to act as a valve, restricting the volume of air delivered to the diffuser. Use a larger I.D. tubing in applications where the tubing is long and/or too restrictive. To make the diffuser lie flat in deep water, use an elbow fitting and put a weight on the tubing to counteract its buoyancy.
