The DFD-LP Dynamic Fire Damper made its debut at the 2017 AHR Expo.
Ruskin’s DFD-LP dynamic fire is the only low-profile integral frame-sleeve high-performance dynamic fire damper in the industry. The 1½-hour rated single aerodynamic blade dynamic (fan on) or static (fan off) fire damper also uses the easiest resettable fuse link in the industry. The easy reset arm helps in testing to meet National Fire Protection Association (NFPA) requirements.
