Series 1000 SM
Brand: T. A. Morrison & Co. Inc
Features
- Smoke dampers are designed for operation in temperatures ranging between -40°F (-40°C) and 250°F (121°C).
- UL/ULC rated Leakage Class 1. This is the best possible leakage class attainable.
- Approved for use with Belimo or Honeywell acutators with 24, 120, or 230 vac, single phase, two-position control.
- AMCA certified for pressure drop.
- Aluminum extrusions contribute to a prolonged and rust-free operational life.
- Bearings are composed of a 2 part (inner and outer) bronze oilite bearing system, fixed to an aluminum hexagon blade pivot pin. This system prevents bearings from rotating directly within the frame and around the axle.
- These dampers are supplied with extremely flexible silicone seals that are resistant to weathering, compression set, and heat, thus ensuring consistent minimal leakage rate performance and sealing longevity.
- Standard blade depth is 6” (152 mm).
