Diffusers

Ultra Fine Bubble Ceramic Plate Diffusers
One of the simplest ways to introduce gases such as oxygen or carbon dioxide, in water is to introduce it as ultra-fine bubbles. This diffuser produces a cloud of ultra fine bubbles, 100 to 500 micron in size. A minimum of 25 psi is required for operating. The diffusers are set in an enamel coated aluminum tray. The operating range is 25 to 50 psi.

Rubber Membrane Air Diffusers
These EPDM rubber air diffusers are incredibly strong and are ideal for pond aeration, circulation, and destratifying applications. Unlike airstones these diffusers are easy to clean, EPDM membrane cleans much better than porous air stones. In testing these diffusers produce a slightly larger air bubble than silica air stones.

Sweetwater Diffuser
Here’s a quality air diffuser that offers the best diffuser technology available. This diffuser has an air resistance of 0.25 psi, which makes this glass-bonded diffuser compatible with economical low-pressure blowers. It produces a uniform medium-fine bubble and is very resistant to clogging. Occasional cleaning is necessary after calcium precipitate or bacteria builds up. May be cleaned and restored to like-new performance by placing in an acid bath. Comes with a 2 year guarantee.

The Sweetwater Diffuser is a high quality ceramic type diffuser that is machined from a solid block of glass bonded silica. This diffuser requires no air filter because dust and dirt particles up to 30 microns in size will pass right through.

Sweetwater diffusers are the best choice for aquaculture, wastewater and lake aerations because of the round grain pore structure, low resistance and uniform porosity. Sweetwater designed this diffuser to produce the smallest bubble possible within the constraints of a reasonable service life. Most soft water applications will not require cleaning for more than a year.
