Pentair Aquatic Eco-Systems Point Four™ MicroBubble DiffusersThe 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. 50% oxygen transfer at a depth of 4' is typical!
Because of the small pore size, a minimum operating pressure of 25 psi is required. Diffusers are set in aluminum frames (AS101-A has a plastic frame). Operating range is 25–50 psi. Two-year warranty. Typical Applications
Aquaculture: For supplemental oxygen to boost fish densities and for emergency backup. For fish transport by truck, barge, boat or plane. Anesthetizing Using Carbon Dioxide: For fish handling and processing. Waste Water and Effluent Treatment: Injection of oxygen to reduce BOD and COD in ponds, channels and large ponds. Ozone Injection: Efficient and effective injection of ozone into water. Note: Diffusers are also known as airstones. |
