Product description

High-Temp Deep-Pleat HEPA Air Filter, 250-450℃ high temperature resistance, designed to remove airborne contaminants in critical areas, in which high efficiency on fine particulate matter is required and where hot air is used during the production process. These filters are used in a board range of industries, from the production of pharmaceutics, photos and films, to food processing. Components used for the assembly of this filter, were either specially selected for their heat resistance or because they are not severely affected by increased temperature.
