3.2" Cylinder Air Diffuser

They produce a bubble size of 1-2mm  and require a higher pressure.

They have a molded aquere rubber support on each end that supports and protects them from tank bottoms and protects the tank or liner from the diffuser. They fit both 3/16" and 1/4" tubing and are 1.2" diameter.


These diffusers are made from alumina that is heat-bonded.

They have a molded square rubber support on each end that protects the diffuser from abrasives.
They fit both 3/16" and 1/4" tubing.

    Super fine bubbles.

    Solid construction and puts out lots of fine bubbles. Worth the cost. I recommend these to friends.
