An air cleaning module includes a filter, a fan, a light source unit, a housing and a guide structure. The fan is configured to provide a suction direction and a blowing direction of a fluid which are substantially aligned. The light source unit is arranged to be adjacent to the filter to emit a light toward the filter. The light having a property that sterilizes a contaminant source in a fluid. The housing includes a fluid passage space. The guide structure is arranged between the fan and the filter and configured to guide a fluid to move along a fluid passage path set by the guide structure. The filter and the light source unit are arranged in the fluid passage space such that the light source unit sterilizes a fluid as a fluid flows toward the light source unit.

An extraction system is designed for metal working and other applications. The system employs a pneumatic filter cleaning device with a pneumatically driven extension guide arranged within a chamber. The guide is coupled to a first end of an extension member, which has a nozzle secured to a second end. Pressurized air provided to the nozzle through the extension member increases until a pressure at the nozzle reaches a threshold pressure level. Once the threshold pressure level is achieved, the nozzle releases a pulse or burst of air directed to a filter medium. The force from the pulsed air dislodges airborne components from the filter media, resulting in a cleaned filter.

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.
