Double leaf smoke vents

Characteristics

  • Smoke vents are used to extract smoke produced by a fire

  • Smoke vents facilitate the evacuation of people by keeping a smoke-free layer in the lower part of the facility

  • They facilitate the rescue team operations

  • Protect the building structure

  • Reduce indirect losses caused by the emitted smoke and hot fire gases

  • Serve as a skylight. They provide more daylight in the premises in which they are installed

  • They can also be used as part of residential ventilation system if appropriate actuators are installed

The upstand and gutter of the upstand of a smoke vent:

  • Upstand made of galvanised steel sheet min. 1.25 mm thick (straight or straight-slant 350, 500, or 750 mm high).

  • The gutter of the upstand is made of galvanised steel sheet  min. 1.25 mm thick. The gutter of the upstand should be insulated with a layer of mineral wool or polystyrene min. 20 mm thick.

 

Compensation frame:

Once the upstand is fixed and finished, the special cut-outs in its corners enable easy snap-fit mounting of the PVC compensation frame.

 

Hinged cover:

The hinged cover consists of two frames and two covers made of cellular polycarbonate.
Smoke vents can be made in Broof (t1)/NRO classification.
The frame is made of PVC or aluminium profile. It is secured around the whole perimeter with gaskets preventing water from getting inside.


Drive:

The smoke vent is activated by two 24 V electric drives or two pneumatic drives. Ventilation function will require to supplement the pneumatic drive with an additional 230 V actuator, while the 24 V drive will suffice for both smoke extraction and ventilation functions.
When a pneumatic drive is used for smoke extraction and an electric drive for ventilation, only one leaf serves the ventilation purpose (one electric actuator is used). At the customer's request, both smoke vent leaves can be used for ventilation (two electric actuators).

  • Large surfaces of smoke vents, up to 300 cm x 300 cm

  • Re1000 – They demonstrate operational reliability in 1000 cycles of opening and closing the smoke vent leaf to the ventilation position,  1000 cycles of activation of the trigger circuit without any loss of efficiency and efficient opening time not longer than 60 seconds

  • SL250 / SL550 / SL900 – reliable operation under a load of 250 N/m2, 550 N/m2 and 900 N/m2

  • WL1500 – wind load resistance up to 1500 Pa

  • B300 – temperature resistance up to 300 °C

  • 1.1-2.5 W/m2K – heat transfer coefficient for the entire product. The coefficient value depends on the choice of cover and upstand variants

  • Cover made of polycarbonate 21 mm, 27 mm, or 33 mm thick in accordance with the NRO/Broof (t1) requirements

  • High values of smoke extraction parameters specified in the Performance Certificate 1488-CPR-0042/W

  • Smoke vent can be equipped with an anti-fall grate or/and a mosquito net

  • Smoke vent can be equipped with anti-fall grab bars

  • Inner side of the upstand can be painted in any colour from the RAL palette

  • Retrofitting the smoke vent with a smoke extraction and ventilation system, e.g., smoke extraction control panel, smoke detectors, emergency buttons
