GVS 1238010 Drain Disc, 37mm, PE, 100pk

The polyester spun-bonded “drain” type disc prevents “pore blinding” or blockage of the capillary pores in screen membranes resulting in higher flow rates and increased throughputs.The new drain disc also increases flow and captures ability by lifting off of screen supports and exposing all the pores. This ensures efficient performance when placed between two filters in a serial filtration stack too.
