The fine bubble disk diffuser combines effective design, low installation cost, reliability and high performance in intermittent and continuous aeration process.
The membrane is made of EPDM or silicone. The unique split pattern and slit shapes disperse air bubbles in an extremely fine and uniform pattern for high oxygen transfer efficiency.
A much highly effective and integrated check valve enables the aeration zones to be easily shut down for air-on/air-off applications. That is, when the airflow is closed, the central part of the membrane falls over the diffuser opening, and the non-perforated area closes the air output.
By connecting the diffuser to an air pump using a pipe elbow and hose connectors, the diffuser creates fine bubbles and ensures effective oxygen enrichment in the pond or pool. Aeration prevents the formation of anaerobic zones and the unpleasant odor of hydrogen sulfide. Additionally, the bubbles help prevent oxygen loss in the water during the summer due to temperature rise. During the winter periods, the bubbles bring warmer water from the bottom of the pond to the top, preventing pond from freezing and allowing overwintering fish to survive until spring.
The fine bubble disk diffuser can be used in freshwater and saltwater aquariums, ponds, hydroponics, biochemical aeration, wastewater, and other industrial aeration applications.
