Xylem Sanitaire - Model Silver Series II LP -Membrane Disc Diffusers
The Sanitaire Silver Series II LP is a 9-inch low-pressure version of the Silver Series II membrane, and features a modified slit pattern to handle airflow up to 20.4 Nm3/h (12 scfm), with minimal pressure loss. Lower energy consumption and raised operating efficiencies are made possible by the unique membrane shape, integrated O-ring and top-sealing threaded retainer ring which eliminates leakage. A highly effective, integrated check valve enables the aeration zones to be easily shut down for air-on/air-off applications. Sanitaire patented pipe joints are designed to withstand thermal expansion and contraction, water hammer and other dynamic stresses, while pipe supports allow infinite height adjustment for accurate grid leveling.
- Ideal for sludge and other heavy-duty applications
