The Washable Primary Filters are designed for general use in ventilation and air conditioning systems in hospitals, office blocks, hotels, factories, AHU’s or areas where there is a high dust content. They can also function as a pre-filter to secondary and tertiary filters.The washable pleated panel filter is made from nonwoven needle punched synthetic media and this is fixed within a galvanised channel frame with urethane, ensuring no air bypass. The supporting wire is sandwiched between two filter medias of varying density
● Low resistance
● High Dust holding capacity
