CX-5 FDG fire dampers

Description

The CX-5 circular fire dampers are used as an air duct closure in case of fire. By activating the damper, the spread of combustion products to the adjacent fire compartment is prevented for a specified period of time. The damper casing is made of galvanized steel sheet. The fire resistance of the damper is EI 120 S (v_e h_o i<->o). The fire dampers are certified according to EN 15 650.

Use

The fire dampers can be used for air free of mechanical and chemical impurities and for environments without explosion hazards.

Variants

The damper is available in two versions, with a fusible safety device (WT72 or WT95), which activates the closing mechanism at temperatures above 72 °C or 95 °C, respectively, or with a servo drive (FDG). The servo drive can be fitted in 24 V or 230 V versions.

Mounting

The CX-5 fire dampers are designed for circular ducts from 100 mm to 630 mm diameter. The damper is designed with an emphasis on minimum pressure drop and is suitable for installation in all common building structures. The damper can be installed with the mounting axis in any position.

Highlights

Fire dampers are fire safety devices, therefore it is necessary to comply with the rules prescribed by the standard (training of installers, carrying out regular operational checks, etc.). Ask for detailed information!
