Matala Air Diffusers

Matala Air Disc Diffusers are available in 3", 7", 9" and 12" diameter sizes. Made of high quality EPDM rubber for use in water gardens, aquaculture and waste water treatment industries. Precision perforated I-shaped slits open when airflow is present and close when airflow is stopped, which increases durability and longevity, as well as cleanliness.  These diffusers offer the lowest back pressure in the market.

MD-3W and MD-7W have weighted bases. MDB11 and MDB22 features a hollow base that can be filled with sand or gravel.

These discs are very low maintenance and in some cases no maintenance. Simply wash the disc with clean water and bleach if it ever needs cleaning.
