  • Filter Casette Consisting a Housing Surrounding a Folded Carpet with Spacers Between Parallel Opposite Filter Carpet Parts
    Publication number: 20080006575
    Abstract: In a filter unit with a folded filter mat that has spacing devices between parallel opposing parts of the filter mat, the contaminants (e.g. liquids) that have been filtered out collect at the bottom of the unit. The air flowing through the unit is capable of sucking up contaminant liquids so that the air leaving the unit, rather than being clean, contains undesirable, previously filtered contaminants. The present invention reduces such additional contamination by so designing/arranging the spacing devices that they prevent additional contamination being added to the air flowing through the filter unit.
