Fine Bubble Membrane Diffusers (BHB-MD225/MD310)
Features and benefits:
- High quality EPDM membrane with highly durable base constructed of molded polypropylene.
- The lowest back pressure membrane diffuser in market.
- Precision perforated I-shaped slits are opened when air flows. The slits are closed when airflow is stopped. In this way slits resist tearing, and stay clean longer.
- A standard 3/4" PT pipe thread allows convenient connection.
- Stainless steel 304 clamping ring holds the membrane firmly in place.
- Double "O" ring shape supports the center of the membrane when airflow is absent.
