Pentair Aquatic Eco-Systems Sweetwater® diffusers are the highest-quality bonded silica type air diffusers on the market today. They're machined from a solid block of glass-bonded silica. Because dust and dirt particles up to 30 microns in size will pass right through these diffusers, there's no need for expensive air filters. And with an air resistance of less than .25 psi, Sweetwater® glassbonded diffusers are compatible with economical low-pressure blowers.

They produce a uniform medium/fine bubble and are very resistant to clogging. And when cleaning does become necessary because of a buildup of calcium precipitate or bacteria, an acid bath restores them to like-new performance.

Models AS1 and AS2 include an ABS slip conical fitting for 3/16” tubing. All PE fittings listed below that do not specify NPT are standard ribbed hose barb fittings.

Note: Water pH in excess of 9.0 will shorten the diffuser life. Self-weighting when used with typical tubing lengths.

More Info

Beware of imitations.

Sweetwater® diffusers are the original 2,000°F glass-bonded silica diffusers introduced by us in 1984. You may come across other diffusers that copy our sizes, descriptions and even our photos, but it takes more than flattering imitation to compete with the best. Look for the name and the two-year warranty.
