CFD-01 E120S Fire Damper
The CFD‑01 E120S Fire & Smoke Damper provides reliable fire and smoke compartmentation within ventilation systems, helping maintain fire-rated divisions through fail-safe closure while allowing effective airflow during normal operation.
Overview
The CFD-01 E120S Fire & Smoke Damper is used in ventilation systems to prevent the spread of fire and smoke between designated divisions. Under normal operation, Fire Dampers will remain in the open position allowing for the ventilation of the associated areas. By definition, Fire Dampers must fail-safe closed to protect the rating of the fire division. This is typically achieved using a spring return system ensuring the damper closes even on loss of power.
Key Features
Casing
The damper casing is formed from 3.0 mm thick sheet steel into a rigid channel section to ensure proper alignment of blades and shafts. The CFD-01 is available as a single unit. The minimum size is 150mm x 150mm and the maximum size is 1000mm x 1000mm, with an insertion length of 300mm. Where circular dampers or dampers with width or height dimensions less than 150 mm are required, additional spigot adaptors are used.
Blades
The blades are a formed double-skin aerofoil section of 1.5 mm sheet metal and operate with an opposed linkage. Blade stops at the top and bottom of the casing and sprung side seals provide excellent low leakage characteristics.
Seals
- Shaft Seals – EPDM, Nitrile or Viton (depending on application)
- Blade Seals – Intumescent and Silicone
