Membrane Diffusers

Membrane diffusers have "I" slots that open as air pressure builds inside the diffuser. The center of the membrane does not have slots and acts as a check valve when air flow stops restricting water from coming up your airline.

Membrane diffusers are heavy duty and corrosion resistant to last for years. They have uniform bubble distribution and and release up to 3 CFM air flow per diffuser pad.

Diffusers have a 3/4" male thread inlet and are 10.5" in diameter.
