AES Air Diffusers - "Air Stone"

AES diffusers are high-quality ceramic-type air diffusers. 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 0.25 psi, AES glassbonded diffusers are compatible with economical low-pressure blowers.

The AES diffusers will 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.
