OVER PRESSURE EQUIPMENT FOR SEVERE ENVIRONMENT

摘要

The present invention relates to an overpressure apparatus for a highly heated and highly dusty environment and to an overpressure apparatus for a highly heated and highly dusty environment, which enhances a filtering performance under the highly dusty environment by improving an assembly structure of a filter. The present invention comprises: a housing provided with an air inlet and an air outlet; a filter assembly filtering foreign materials contained in air flowing into via the inlet; a heat exchanger cooling air passed through the filter assembly; and an overpressure unit sucking and pressing air passed through the heat exchanger to blow the air to the outlet, wherein the housing is provided with a filter duct in which the filter assembly is housed, and the filter assembly includes: a plurality of filters inserted into the filter duct and a filter holding frame inserted into the filters to seal gaps between the filters.
