Depth Filter Sheets

In depth filtration, liquids are forced through the three-dimensional matrix of the sheet. It is within this matrix that the particles are trapped. Depth filters are most often used in applications with higher dirt loads where other "surface" filters do not provide sufficient life. Depth filters typically have a thickness of 3 - 4 mm which is 3000 - 4000 times the size of a 1 micron particle thus enabling the entrapment of millions of microparticles in every square metre of filter area.

Carlson's series of depth filter sheets comprises a complete range of products tailored specially for applications where purity and quality are paramount. From the removal of coarse matter right through to sterilising filtration, there is a product ideally suited for all applications. All products are carefully formulated to provide particular filtration characteristics. Ongoing investment in manufacturing facilities, coupled with stringent quality management practices (backed up by conformance to ISO9001:2008), ensure consistent product quality. All "white" sheets are laser etched on the outlet / smooth side with grade and batch number for complete traceability; the production date is shown on the external packaging.

The range comprises a number of main product groups:
XE range of filter sheets - for use in clarifying and sterilising filtration duties
EE range of sheets for use where all cellulose fibre sheets are needed
W2N support sheet for use with kieselguhr/perlite in coarse filtration of bulk liquids, such as in beer and lager production, fruit juice manufacture or the processing of gelatine
XS range of speciality sheets for more demanding applications including spirit filtration
BK range - for high performance speciality applications
Proc 3 sheets which incorporate activated carbon for colour, odour and taste correction.
