New! Integral Sleeve Design (Alternate)
ABI is pleased to produce another industry first:
Smoke Dampers with an Integral Sleeve.

The advantages of this boldly unique design are numerous:

  • A constant blade stop height of 3/4" for maximum pressure drop
  • A single blade (max. 24" x 16") for maximum free area
  • Shorter sleeve protrusion on the actuator side (by 3")
  • Reduced size actuator envelope dimensions
  • An inexpensive 24 VAC, 250-degree F Multi-Products actuator
  • An inexpensive 120 VAC, 350-degree F Multi-Products actuator
  • Dual direction air flow
  • Invertability - If the installation site requires the actuator to be on the other side, just turn it over!
  • Lighter (about 15%) and easier to install
