Models and Accessories

POREX Plastic Filter Housings are available in two design casings – a small head with a short or a long cup and a large head (dimensions shown below). Filter housings come standard in white; however, other color options are available based on quantity requirements. Alternatively cups can be offered in transparent design. Each standard polyethylene filter element is available in three different porosities. Further porosities can be produced given that a certain quantity is required.

  1. Size of Head Connection (Material: 20% GFR Polypropylene)
  2. Porosity of Polyethylene Units: 5μm, 35μm and 80μm Meshes of stainless steel units: 50µm, 100µm and 300µm (PP support core necessary)
  3. Material Beakers: Polyamide (transparent); 20% TR Polypropylene (white)
  4. Material Seal Ring: NBR (black), EPDM (white), FKM (green)

Filter Unit Soiling

Use transparent filter cups for simple, quick inspection of the filter unit soiling. More economical polypropylene beakers are available for applications not requiring constant control. 

Changing Filter Unit

Simply unscrew the head from the beaker and remove the filter unit. The filter unit is inserted into the head using a press fit (PE unit) or by clamping (stainless steel unit with support core). Change the seal with every filter change to ensure that the housing remains properly sealed. Please refer to the Instruction Manual for proper assembly of the filter housing.
