Matala 9″ Fine Bubble Membrane Diffuser Disc Plus Single Base
The Matala MDB11H diffuser platform includes a 9 inch fine bubble membrane diffuser mounted on a single hollow platform that can be filled with sand or gravel which eliminates the need for bricks, straps or other home made devices to get it to sink. The Matala 9″ fine bubble membrane diffuser is made out of heavy duty EPDM rubber membrane fixed to a highly durable moulded polypropylene base. The membrane has precision perforated slits that open when airflow is present and close when airflow is stopped. In this way slits resist tearing and stay cleaner longer. The Matala fine bubble membrane diffuser has a standard 3/4″ PT pipe thread that allows convenient connection. A 304 grade stainless steel clamping ring holds the membrane firmly in place. Triple o-rings support the centre of the membrane when airflow is absent. A single Matala fine bubble membrane diffuser handles airflows between 40-120lpm or 1.4-4.2cfm. The Matala fine bubble membrane diffusers offer the lowest back pressure available in the market adding less than 6 inches of water depth back pressure, allowing you to utilise your air pump in the most efficient way. Matala diffusers are used worldwide for pond aeration, dam aeration, lake aeration, lagoon aeration, waste water aeration, food processing aeration, aquaculture aeration and virtually any water application requiring aeration. The Matala MDB11H diffuser platform is ideal for aerating lakes, lagoons or dams because the membrane diffuser is screwed onto the base via a riser that lifts the membrane up out of the muck on the bottom.
