IMPROVED FILTER CONSTRUCTION FOR REMOVING CONTAMINANTS FROM AN ENCLOSURE

摘要

The invention relates to a device for filtering contaminants, such as particulates and vapor phase contaminants, from a confined environment such as electronic or optical devices susceptible to contamination (e.g. computer dis drives) by providing a filter for an improved fit within the enclosure. Filtration functions include a recirculation filter and optional adsorbent recirculation filter.
