Abstract
The invention is directed to a passive dust filtering system for an inspection hatch of steel bulk storage vessel. The system includes a filter containment unit and an adaptor section for securing the unit to the storage vessel. The adaptor section includes a mounting flange having one or more magnetic switches to engage the storage vessel. A purge control system is used to periodically pulse air into filter elements in the filter containment unit to blow dust from the outside of the filter elements back into the vessel.
