A modular air-handling system includes a number of air-handling modules joined together in a desired configuration. The modules house air-handling units, such as a fan-and-motor unit, a helical filter unit, and/or a Hepa filter unit. Sealing devices for sealing the air-handling modules include a sealing gasket, and the sealing gaskets preferably are of a common shape. Each sealing gasket includes a retention tab. A gasket channel of each sealing device is constructed to compress and retain the sealing gasket. The gasket channel includes a gasket retainer extending along the sealing gasket, abutting the retention tab. The gasket retainer engages and compresses the sealing gasket adjacent the retention tab, holding the sealing gasket within the gasket channel during assembly of the air-handling system. The gasket channel defines an open side during assembly of the air-handling system, at which open side the sealing gasket is exposed.
