Filter Module
The lenticular module concept offers a compact, self contained, liquid filtration solution utilising proven filter media technology.
Carlson lenticular filters are essentially composed of Carlson depth filter media, supported on a polypropylene skeleton and supplied in modular form normally comprising 16 cells of either 12” (300mm) or 16” (400mm) diameter. They offer all the advantages of traditional sheet filtration, but in a totally enclosed, sterile, environment, thus eliminating product loss and external contamination. They are designed to fit industry standard housings incorporating 1, 2, 3 or 4 modules
Technical Information
The lenticular filter modules are of either 12” (300mm) or 16” (400mm) diameter, to match the appropriate housing. Each module is normally made up of 16 cells. Each cell consists of 2 discs of filter media formed around an internal, all polypropylene skeleton. The outer edges of the media are sealed with an injection moulded polypropylene strip. The complete filter module is assembled from up to 16 cells packed together with a special internal polypropylene structure allowing the formation of a completely sealed, pre compressed unit. These modules can then be used in a single or multiple housing, stacked end to end up to 4 high. End seal is via either flat gasket or double o-ring bayonet fitting.

Product Benefits
- The system is pre-assembled and as such is very convenient to use. Consequently significant productivity gains can be achieved due to shorter changeover times.
- The range of filter media which can be incorporated in this design permits use of the lenticular system in a wide variety of applications.
- The totally enclosed construction of the system is ideal where hygiene is important or the conditions hazardous.
- The design of the Carlson lenticular gives improved lateral strength and rigidity.
- Heavy duty non-woven polyester scrim gives improved resistance to back pressure shock and much improved back washing capability in addition to the provision of an appreciable degree of pre-filtration prior to the depth filter medium
- Pre- compression during manufacture to precise dimensions eliminates the need for additional tightening down procedures.
- Advanced design of the polypropylene separator discs and sealing rings promotes a more even liquid flow within each cell. This in turn reduces the pressure drop across the filter module, leading to longer filter life and filtration cycles plus more consistent filtrate quality.
- Both flat gaskets and double o-ring end fittings are available to fit all lenticular housings
