Rex-Flex® diffusers consistently produce 1 – 3 mm fine bubbles through thousands of uniform circular apertures in the flexible membrane.
When the air is turned on, the membrane expands and rises off its seat. At operating pressure, the apertures open to release a controlled, energy efficient stream of fine bubbles.
When the membrane is periodically deflated, the apertures close and surface deposits are sloughed off. This significantly reduces the possibility of clogging, plugging and fouling that adversely affect oxygen delivery rates.
