Ruskin has released its new DFD-LP dynamic fire damper, which is rated for dual-direction airflow and can be installed vertically in walls or horizontally in masonry floors. The one-and-a-half-hour rated single aerodynamic blade dynamic (with fan on) or static (with fan off) fire damper uses a resettable fuse link. The reset arm helps in testing to meet National Fire Protection Association requirements. The damper is rated for 4,000 feet per minute and has a standard static pressure of 4 inches on all sizes. The standard DFD-LP assembly is supplied with a 16-inch sleeve and is designed to be installed in walls or floors up to 8 inches deep.
