Patent number: 7597534Abstract: A fan array fan section in air-handling system includes a plurality of fan units arranged in a fan array. Each fan unit is positioned within a fan unit chamber/cell. Each fan unit chamber/cell has at least one acoustically absorptive insulation surface. The insulation surfaces of the fan unit chamber/cells together form a coplanar silencer. Sound waves from the fan units passing through the insulation surface at least partially dissipate as they pass therethrough. In one preferred embodiments the fan unit chamber/cell is a cell having a frame that supports the insulation surface.Type: GrantFiled: March 31, 2005Date of Patent: October 6, 2009Assignee: Huntair, Inc.Inventor: Lawrence G. Hopkins

Patent number: 6050774Abstract: A modular fan filter unit designed to supply process control air to mini-enclosure clean rooms. The modular fan filter unit is easy to remove, repair, and replace in the clean room environment. It has a readily accessible filter mounted across its bottom surface and an internal variable frequency drive fan. The fan pushes air through the filter into a clean room. Multiple numbers of modular fan filter units may be connected together as an array.Type: GrantFiled: October 14, 1998Date of Patent: April 18, 2000Assignee: Huntair Inc.Inventor: James F. LeBaron

Patent number: 5960638Abstract: This patent discloses a modular environmental control system for small cleanroom enclosures ("mini-enclosures"). Small environmental control units ("ECUs") are mounted on top of individual mini-enclosures, as near as possible to the process tool within the enclosure. Each ECU has the capability of controlling temperature, humidity, and airflow rate delivered into the enclosure. Temperature is adjusted by first cooling the air inside the ECU followed by reheating it to a selected temperature. The cooling capability is not generated by individual ECUs. Instead, a remote fluid cooling unit supplies chilled fluid to each ECU, which is circulated internally to cool the air. The same remote unit services different ECUs at the same time.Type: GrantFiled: August 15, 1997Date of Patent: October 5, 1999Assignee: Huntair Inc.Inventors: Chuck K. McCabe, Greg A. Marvell

Patent number: 5855823Abstract: The present invention is a humidifier that provides uniformly controlled generation of water vapor into an air stream. Steel wool is placed into a heating section of a humidifier water reservoir, where vapor is produced, to create an even distribution of vapor exiting the humidifier. A perforated plate is horizontally inserted into the heating section above the steel wool, thereby holding it in place and aiding in the even distribution of vapor from the humidifier.Type: GrantFiled: May 16, 1997Date of Patent: January 5, 1999Assignee: Huntair Inc.Inventors: Bruce S. MacGibbon, Christopher P. Sirovy, Mark C. Wolochuk, Travis J. Addington, Chuck K. McCabe, Greg A. Marvell
