Patent number: 10512866Abstract: A filter housing can support filter media for a fan arrangement. The filter housing can include a filter body with a first opening at a first end and a second opening at a second end. A bell portion can be disposed between the air inlet opening and the air outlet opening and can define a cavity within the housing body. An air-permeable filter support can extend into the cavity to support the filter media within the cavity, with the filter media spaced apart from at least one of the first and second openings.Type: GrantFiled: February 14, 2017Date of Patent: December 24, 2019Assignee: Hoffman Enclosures, Inc.Inventors: Seng Chang, Douglas L.

Patent number: 8814224Abstract: Embodiments of the invention provide a suspension system for supporting an enclosure. The system includes a compression fitting that couples an enclosure mounting assembly to a hollow connector tube and provides a substantially sealed pathway between the enclosure mounting assembly to the hollow connector tube. The compression fitting includes at least one coupling body and at least one compression nut. The compression nuts are tightened around portions of the coupling bodies to secure end portions of the enclosure mounting assembly and the hollow connector tube within the coupling bodies.Type: GrantFiled: November 11, 2010Date of Patent: August 26, 2014Assignee: Hoffman Enclosures, Inc.Inventors: Timothy G. Lange, Jamie M. Livgard, William J. Nepsha, Nathan P. Espinosa

Publication number: 20140001932Abstract: A modular, ventilated enclosure includes a base and a frame coupled to the base. The base includes at least one mounting receptacle for mounting a fan. The enclosure can include four side panels coupled to the frame and a back panel coupled to the frame in the interior of the enclosure. The back panel can be adapted to mount electrical equipment. A cover can be coupled to the frame and can include an overhang to prevent debris from entering the interior of the enclosure. The enclosure can also include a gravity controlled damper system with a damper that moves to an open position when an internal pressure in the interior of the enclosure increases. The enclosure can include a passive air flow passage that ventilates the enclosure when the damper is in the closed position.Type: ApplicationFiled: June 29, 2012Publication date: January 2, 2014Inventors: Nathan L. Westby, Trent T. Jones, William J. Nepsha, Jamie M. Livgard

Patent number: 6564428Abstract: A compound hinge system includes a first link and a second link. The first link includes knuckles and arcing engaging surfaces next to stop portions that are configured for receiving engaging lug portions on a second link member. A second link member includes first and second sets of knuckles. One of the sets of knuckles cooperates with a hinged pin to pivot relative to the first link while the second set of knuckles receives a hinge pin to pivot relative to the second element. The lugs slide relative to the engaging surface and push against the stop portions to flex them outward and require additional force to move between various stops in the range of motion.Type: GrantFiled: January 12, 2001Date of Patent: May 20, 2003Assignee: Hoffman Enclosures, Inc.Inventors: John E. Richard, Craig E. Schinzel, Wallace H. Polzin, Clifford A. Klinger, William J. Nepsha, Marvin J. Thibodeau
