Matala 2 x 9″ Fine Bubble Membrane Diffuser Discs Plus Double Base
The Matala MDB22 diffuser platform includes two 9 inch fine bubble membrane diffusers mounted on two hollow platforms 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. The Matala MDB22 air diffuser platform includes a quick uni-pack that easily connects the two Matala platforms with only one 3/4″ PT threaded connector. This doubles the aeration performance without an extra air pump or tubing/hose. 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 MDB22 diffuser platform is ideal for aerating Koi ponds or fish ponds because the membrane diffusers are screwed into the base and leave no gaps for fish to hide or scrape themselves while swimming. The Matala air diffuser platform allows for easy placement on the bottom of the pond while keeping the membrane out of the muck.
