All CFPDirect panel filters are constructed with enclosure frames made of two die-cut pieces of heavy duty Beverage Board bonded together to form a double wall. It is treated with a moisture resistant additive to prevent collapse during high humidity. The support members of the enclosure frame are bonded to the media and grid combination to maintain correct pleat spacing. Concept Filter Products offer the
complete range of panel filters Design The Dura-Pleat operates on a principle of filtration which ultilises controlled pleat spacing and alignment. This controlled configuration assures uniform airflow throughout the filter. Initially the least resistance to airflow is at the bottom of the pleat where contaminants are filtered out. As the contaminants build up, the resistance at the bottom of the pleat increases and airflow gradually moves up the sides of the pleat. Larger dirt particles are trapped in the back of the pleat as their inertia prevents directional change, while the smaller particles, being able to change direction are caught along the sides of the pleat. As the particulate matter builds up it functions as an additional filtration medium. Construction The filter media is made up of reinforced non-woven cotton fibres manufactured for high dust holding capacity. It is treated with a fire retardant additive for safety purposes. The filter media is bonded to an expanded metal (diamond pattern) support grid. The grid has a 98% open-face area for increased media utilisation. The media and grid design is bonded to the periphery of the enclosure frame to prevent air bypass. This design provides uniform pleat configuration for maximum performance.
Performance Air filter performance is measured by dust holding capacity and filtration efficiency. Greater dust holding capacity means longer service life and lower operating costs. Greater efficiency means cleaner air and reduced maintenance costs. Dura-Pleat filters excel in both of these performance characteristics. Summary
CFPDirect's disposable Dura Glass Panel Filter is a low / medium grade filter ideal for use in heating or ventilation applications and as a prefilter to high efficiency filters in air handling serving critical areas. Design & Manufacture Our Dura Glass Panels use a continuous filament glass fibre media with a graduated density and open structure on the upstream including microfine backing on the downstream. This glass fibre media is ideal when used as a high dust holding pre-filter. To ensure there is no air bypass glue is applied to the surfaces of the card frame creating an airtight seal upon contact with the glass fibre media.
