Filtrox - Lenticular Modules
and Housings for Depth Filtration

Closed, leakage free filter for the use of compact lenticular modules.

Filtrox - Lenticular Modules
Filter modules for depth filtration allow you to achieve sheet filtration with extreme ease of handling. Filter sheets are mounted in a lenticular form on a draining body. A filter module contains several stacked lenticulars which are held together either by metal clamps or by a grid-like core sleeve of PP. Sealing rings between the lenticulars prevent the passage of non-filtered substance.

In the DISCSTAR, several modules can be applied in combination, allowing the filter area to be multiplied in simple steps.

Filter modules allow filtration in an enclosed system without dripping loss. DISCSTAR 30 and DISCSTAR 40 are the economical filter module units. Module filtration allows outstanding filtration results to be achieved in a closed system without drip losses. Very easy handling. Only a small number of modules have to be handled for inserting new and disposing of used filter media. The DISCSTAR offers many extras, both as standard or as options.

Closed, leakage free filter for the use of compact lenticular modules.

Technical data for standard modules (with flat adapter):


Proven depth filter media (same quality as standard filter sheets, mainly H-series).

Materials of construction:

Stainless Steel or Hastalloy Poypropylene (FDA quality) Prefiltration effect by PE-nonwoven and higher resistnace to back pressure


Standard = Silicone, EPDM, VITON, PTFE etc. available on request

Delivery units:

12" = box with 2 pieces

16" = box with 1 piece

Remark: Filter area can be reduced and cake volume increased by using fewer cells per standard size module. Details on request. Also available are smalller sized modules with 2, 4, 8, 9, 15 cells for use where smaller hold-up volumes, lower flow rates or lower filtration volumes are required. Again details are available on request.
