Backdraft Damper

Series 7600: Heavy-Duty

Tamco heavy-duty backdraft dampers are constructed with robust components to withstand up to 12” w.g. (3.0 kPa) of static pressure and velocities up to 3500 fpm (17.8 m/s).
Blades are designed with a rounded head. This reduces pressure loss.
Tamco’s dual bearing linkage system is self-sealing, self-lubricating, and non-absorbent, resulting in a maintenance-free performance.
Silicone seals are provided as standard to ensure sealing longevity and remain flexible down to -40° F/C.
Tamco heavy-duty backdraft dampers are available in four install types: Installed In Duct, Flanged to Duct, Extended Front Flange, and Extended Rear Flange.
For horizontal and vertical airflow operation

Specifically designed for installations requiring a heavy-duty backdraft damper, subjected to elevated velocities and operating pressures
Recommended for use in high-pressure isolation systems, air handling units, gen sets, and fan inlet or fan outlet locations
They are an excellent solution whenever resistance to vibration in fan isolation systems or resistance to the effects of turbulent air is necessary.

Heavy-duty backdraft dampers with the ET Option are designed for operation in temperatures as high as 300°F (149°C).
Bronze-oilite bearings replace Celcon and polycarbonate bearings.

All zinc-plated steel hardware is replaced with stainless steel, protecting hardware from rust and corrosion when exposed to high humidity or high moisture environments.

Extruded aluminum frames, blades and hardware are clear anodized to a depth of 0.7 mil. (18 microns). This prevents rusting and pitting when heavy-duty backdraft dampers are exposed to salt spray or high humidity environments.
All zinc-plated, steel hardware is replaced wtih stainless steel, protecting hardware from rust and corrosion.
All aluminum linkage hardware parts are clear anodized.
