Machined from a solid plate of 2000° glass bonded silica, our diffusers produce a uniform medium-fine bubble and are resistant to clogging {dust/dirt particles up to 30 microns in size pass right through}. An acid bath restores the air diffuser to like-new performance when cleaning becomes necessary. Most soft water applications will not require cleaning for more than a year.
With an air resistance of 0.25 psi, these air diffusers are compatible with economical low pressure blowers. They are self-weighting with typical tubing lengths, Made in the U.S.A. and guaranteed for two years.
These air diffusers are the best choice for aquaculture, wastewater and lake aerations because of the round grain pore structure, low resistance and uniform porosity.
