A sorbent filter for use with an air-purifying apparatus. The filter includes a flexible bag and a sorbent material in granular form. The flexible bag defines at least one storage region and is formed of a porous material. The sorbent material is disposed within the storage region. With this configuration, the porosity of the flexible bag is configured to allow passage of air such that the air, including air-borne gaseous molecules or odors, can interact with and be adsorbed by the sorbent material. Conversely, however, the porosity of the flexible bag limits passage of sorbent material granules and dust. As such, the filter generates little if any dust during handling. In one preferred embodiment, the flexible bag is selectively attachable to a separate frame that in turn is designed for mounting within the air-purifying apparatus. With this configuration, the frame can be re-used such that filter replacement requires only a new sorbent filter.

Non-dusting sorbent material filter

An air-purifying system for filtering and re-circulating room air. The air-purifying system includes a blower module, a first filter module, a second filter module and a supply module. The blower module defines a first inlet, a second inlet and an outlet. The first filter module is spaced from the blower module, and is fluidly connected to the first inlet. Similarly, the second filter module is spaced from the blower module and the first filter module. The second filter module is fluidly connected to the second inlet. Finally, the supply module is spaced from the blower module and the filter modules. The supply module is fluidly connected to the outlet. With this configuration, the blower module is operated to draw air into the first and second filter modules for removal of contaminants. Further, the blower module forces cleansed air to the supply module.

Air-purifying system

A blower module for use with a commercial air-purifying system. The blower module includes a housing, a blower unit and a chute. The housing defines an inlet region and an outlet region. The inlet region forms an intake port. The outlet region forms a supply port and an exhaust port. The blower unit is maintained within the housing, such that operation of the blower generates an airflow within the housing from the inlet region to the outlet region. Finally, the chute is mounted within the outlet region adjacent the exhaust port and is configured to direct a portion of the airflow to the exhaust port. With this configuration, an overall size of the blower module housing is greatly reduced.

A filter module for use with a room air-purifying system. The filter module includes a housing and a filter. The housing forms an air inlet, a first outlet port and a second outlet port. The outlet ports are configured for fluid connection to commercial ductwork. The filter is maintained by the housing and is configured to retain air-borne contaminants. During use, airflow passes from the filter to the outlet ports. By incorporating at least two outlet ports, the filter module preferably assumes a low-profile configuration, thereby facilitating installation of the filter module at any desired location relative to a room of interest.

Low-profile air filter module

A filter assembly for use with a commercial air filtration unit. The filter assembly includes a frame, a sorbent material filter, and a primary particulate filter. The frame defines an upstream portion and a downstream portion, with the upstream portion forming a lip. The sorbent material filter is coupled to the downstream portion. Conversely, the primary particulate filter is coupled to the upstream portion of the frame. In this regard, the primary particulate filter defines an inner face and an outer face. Upon assembly, the inner face is adjacent the sorbent material filter and the lip projects upstream of the outer face. During use, the lip provides a receiving surface for installation within a housing, while preventing damage to the filter materials. Further, the filter assembly can be selectively maneuvered to a partially released position relative to the housing whereby the filter assembly hangs freely from the housing, supported at the lip.

An electrical connector for an oxidized surface includes a plurality of spaced apart parallel connector legs integrally formed as extensions of a central connector spine. Each connector leg has a free standing integral barb projecting therefrom toward an adjacent one of the connector legs. A group of legs is arranged to straddle a metal plate having an oxidized surface with the pointed ends of the barbs having a separation less than the thickness of the plate to enable the barbs to scrape the oxide from the surface to establish electrical contact to the underlying metal layer. The connector, in turn, is made of phosphor bronze to enable a spring-loaded electrical contact to be made to the connector surface by providing a low resistance non-oxidizing contacting surface. A use for such as connector would be to provide an effective electrical connection to aluminum plates such as those used in an electrostatic precipitator where the aluminum oxide forms an electrical current barrier and the connector is required to have a low resistance surface to contact a spring-loaded connector extending from a high voltage source to the collector plates. The use of an extended connector spine enables the connector to bridge a pair of plates while providing individual electrical connections thereto.
