Microbubble Plate Diffusers

Product Description
The Point Four Diffuser produces a cloud of extremely fine bubbles, 100 to 500 microns, much finer than graphite or carborundum diffusers or porous hose. Because the diffuser is flat, bubbles do not coalesce as happens with circular diffusers. The Point Four Diffuser uses a fine pore ceramic plate, which produces uniform bubbles across its entire surface.

The ceramic plate is set in a rigid enamel coated aluminum frame. A wet diffuser will not break if frozen. Compared to other diffusers, you will use less gas and require fewer diffusers to achieve the same result.
