Product description
Description

The MDF30 EURO square fire dampers are used as a closure for air ducts in case of fire. When the damper is closed, the spread of fire and the spread of smoke through the pipe from one fire section to another is prevented. Activation of the damper in case of fire is ensured by a 72 °C thermal fuse as standard (95 °C on request). Closure of the damper after activation of the thermal fuse is ensured by a mechanism fitted with a closing spring. The damper shell is made of two parts made of galvanised steel sheet, separated by a calcium silicate plate to prevent heat transfer. It is fitted with two inspection holes. The flap sheet is made of calcium silicate plates. The blade rotates on steel pins mounted in bronze bushings. The flapper is fitted with a limit switch (CLOSED). The flapper is designed with minimum pressure loss in mind. The damper is provided with a flange at both ends for connection to the air piping.

Features

CE marking according to EN 15650 certification, classification according to EN 13 501-3 is EI 90/120 S. Tested according to EN 1366-2 at 500 Pa.

Use

The flaps are suitable for installation in all common building structures such as rigid wall structures, lightweight partitions or rigid ceiling structures. The flap can be installed in fire separating construction with the axis of the sheet vertically or horizontally. Fire dampers can only be used for air free of mechanical and chemical impurities. Maximum flow velocity 10 m/s.

Mounting

The fire dampers are designed for square air ducts from 200x200 mm to 1500x800 mm (width x height). The axis of the damper must be inside the fire separation structure.

Notice

Fire dampers are dedicated fire-safety devices (see the Ministry of the Interior Decree on fire prevention), therefore it is necessary to follow the prescribed rules (training of installers, regular operational checks, etc.). Ask for information!
