Smoke Vents

Single Leaf Smoke Vents

Smoke dampers are an important component of gravitational smoke extraction, used to vent harmful substances generated during a fire. Thanks to its sunlight-permeable cover, it can also serve as a rooflight. Due to the performance characteristics, they are designed for installation on flat roofs (up to 15°). Smoke dampers are widely used in large-scale facilities: production halls, logistics centers, warehouses, sports facilities, skyscrapers, shopping malls. They can be made in two variants: single-wing and double-wing.

Product features

Robust and Customizable Base Construction

The smoke damper base is engineered from high-durability galvanized steel sheet (minimum thickness of 1.25 mm) composed of four distinct segments. To accommodate various roof structures and technical requirements, the base height is highly customizable, ranging from 300 mm to 1000 mm, with standard availability at 350, 500, and 750 mm.

Multi-Functional Covering Options & Solar Control

The system offers diverse covering choices to meet specific thermal and fire safety needs, including multi-thickness cellular polycarbonate (up to 25 mm) with built-in UV filters, acrylic or solid polycarbonate domes, and fire-retardant Kera Fire Protect panels (BROOF(t1) class). Additionally, an optional Solar Control coating protects interiors from excessive summer heat by regulating solar radiation transmission.

Dual-Type Actuation Systems

To ensure flexible and reliable deployment, the smoke dampers utilize two distinct types of opening mechanisms: electrical and pneumatic. The electrical system relies on 24 VDC actuators operating with a current ranging from 2.0 A to 8.0 A. Alternatively, the pneumatic variant utilizes one- or two-way actuators powered by CO2 cartridges, which incorporate a dual-actuator setup for double-wing configurations to ensure one dedicated actuator operates each wing.

Certified High-Performance Technical Ratings

The smoke dampers boast high performance certified to the EN 12101-2:2003 standard (CE mark 1488-CPR-0042/W). They offer proven operational reliability over 1,000 fire-position cycles (Re 1000) and feature certified heat resistance up to 600 °C (B 600). Additionally, the system opens in under 60 seconds while resisting wind loads up to 1,500 Pa (WL 1500) and snow loads up to 900 N/m² (SL 900).

Dual-Function Daily Ventilation & Security Options

Beyond emergency smoke extraction, the units can be converted into dual-function dampers by integrating a daily natural ventilation system (utilizing the existing 24 VDC electric actuator or a dedicated 230 VAC/pneumatic drive). Safety and utility are further enhanced through optional roof hatch functionality for roof access, anti-drop gratings, custom RAL color painting, and full integration with external control units, smoke detectors, and alarm buttons.

Smoke damper base:

composed of four segments made of galvanized steel sheet with a thickness of min. 1.25 mm. Base height adapted to the roof structure and technical requirements, from 300 to 1000 mm. Standard heights: 350, 500, 750 mm. Smoke damper bases require a support structure around the perimeter.

Cover:

  • Cellular polycarbonate (PC) – thickness of choice 10, 16, 20, 25 mm. The outer layer of polycarbonate covered with a coating containing a UV filter;

  • Fire retardant Kera Fire Protect panel – BROOF(t1) class external fire retardant, selectable thicknesses of 21, 27, 33 mm;

  • Domes – single or multilayer, material of choice: acrylic / solid polycarbonate;

  • translucency – klar (transparent) or opal (milky, standard for fire retardant Kera Fire Protect panels);

  • Solar Control – chambered polycarbonate covered with a special additional coating that allows to control the amount of solar radiation passing through the panel. As a result, rooms are better protected from excessive heat in the summer.

Actuators:

Two types of actuators are used to open smoke dampers:

  • Electrical – 24 VDC with a current of 2.0 A to 8.0 A;

  • Pneumatic – one- or two-way actuators using CO2 cartridges. In the case of double-wing smoke dampers, two actuators are installed
(one per wing).

Smoke deflector:

An additional element that increases the smoke damper's active smoke extraction area, made of galvanized steel sheet.

Directional nozzle:

An additional element that increases the smoke damper's active smoke extraction area, made of sheet metal.

  • High values of smoke extraction parameters specified in the Deklar ation of Permanent Performance with CE mark 1488-CPR-0042/W according to EN 12101-2:2003;

  • Re 1000 - reliable operation during 1000 cycles of opening and closing the smoke damper sash to the fire position. This means 1000 times activation of the trigger system without loss of efficiency;

  • SL 250/SL 550/SL 650/SL 900 - reliable operation under load of 250 N/m2, 550 N/m2, 650 N/m2 or 900 N/m2 respectively, opening time less than 60 s.

Essential dimensions and characteristics in accordance with the harmonized standard

  • T (00) - products of this class are considered suitable for use in building structures with temperatures higher than 0 °C;

  • WL 1500 - wind load resistance equal to 1,500 Pa, opening time less than 60 s;

  • B 300/B 600 - temperature resistance, respectively: 300 °C and 600 °C;

Additional options:

  • Ventilation - a ventilation system is additionally mounted to the dampers (dual function damper), which allows natural and economical ventilation of rooms on a daily basis. If the damper is equipped with an electric drive, the smoke extraction and ventilation function is operated by the same 24 VDC actuator, while in the case of pneumatic control of the system, an additional actuator powered by 230 VAC or a pneumatic actuator is installed. As a standard for a two-wing smoke damper, one actuator is used for the ventilation function (one of the wings is opened);

  • Roof hatch - a function that allows you to go to the roof surface;

  • Anti-drop grating;

  • The inner side of the base can be painted in any RAL color (standard: 9010, 9002 or 9003);

  • Retrofitting the smoke damper with a smoke and ventilation system, such as a smoke control unit (Actulux, AFG), smoke detectors, alarm buttons.
