Point Four Ultra-Fine Bubble Diffusers
Aeration » Fine Pore Oxygen & Ozone Diffusers »
The original is still the best!
These high-quality, resin-bonded, ceramic plate diffusers are recommended where pure gas, including oxygen and carbon dioxide, is to be used. They produce a cloud of ultra-fine bubbles, 100-500 microns in size, for excellent gas transfer. Fifty percent oxygen transfer at a depth of 4' is typical!
Because of the small pore size, a minimum operating pressure of 25 psi is required. The diffusers are set in enamel-coated aluminum frames. Operating range is 25-50 psi. Guaranteed not to break if frozen. Two-year warranty. Made in Canada by Point Four Systems, Inc.
