​Our polyester drain discs are typically used as a spacer between stacked membranes; they are ideal for increasing
flowrates in PCTE and PETE membranes. 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. The spacers prevent
air locking of the downstream screen, or function as filters by binding a percentage of pores in the upstream filter. The spacer
may 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.
