Osmonics* Drain Disc Mesh Spacers

The drain type disc prevents pore binding or blockage for the capillary pores in screen membranes resulting in higher flow rates and increased throughputs. The new drain disc also increases flow and capture ability by lifting off of screen supports and exposing all the pores. The spacer should be sized to fit within the diameter of the O-ring in the filter holder. For example, use a 42 mm spacer under a 47 mm filter.
