Description

mcr FID B cut-off dampers are intended for installation in fire ventilation systems operated manually (feature MA) and automatically (feature AA).

They support single fire zones, as well as several zones within a single facility.

They prevent the spread of fire, smoke and fire gases to neighboring zones. The dampers can operate in so-called mixed systems.

  • first multi-stage damper of Polish production
  • made of mcr SILBOARD fire protection board
  • full compatibility with fireproof ducts
  • operational reliability up to 10,000 cycles
  • inspection opening as standard
  • external Casing leakage class C, internal leakage class 2 acc. to EN 1751

 

Dimensions for rectangular dampers:

  • nominal width from 200 to 1200 mm
  • nominal height from 200 to 800 mm
  • maximum area of section of single damper not larger than 0.96 m2

Apart from standard dimensions, dampers can be customized to any size within the specified ranges.

 

Control:

  • Belimo type mechanism – actuators family without return spring, without thermoelectric trigger.
