CFI All Metallic Viscous Filters are washable type filters used as pre-filters for general ventilation and air conditioning.
The CFI All Metallic Viscous Filter is constructed using 5 layers of G.I. wire mesh interspersed with 2 crimped layers and 3 flat layers. The media is supported with expanded metal from both sides as reinforcement and fitted in 50 mm metal frame. the filter media ensures maximum filteration area resulting in nominal differential pressure and high dust holding capacity. The filter is required to be impregnated with oil before use.
CFI All Metallic Viscous Filter comes in various sizes but generally the size is 610 x 610 x 50 mm.
