Matala Single 9 Inch Air Membrane Diffuser (Only)

The Matala Membrane Diffuser gives out medium size bubbles through the rubber membrane with very low back pressure. It allows the air pump to operate efficiently. The diffuser has a 3/4" male thread on the bottom. The 9" disc can take air flow from 25 LPM to 80 LPM. The membrane is very easy to clean if it is ever even needed.
