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.
