Double Leaf Smoke Vents

The AWAK double-leaf smoke vent is a certified natural smoke and heat exhaust ventilator, designed for large roof openings. Its two symmetrical leaves open simultaneously, providing a larger aerodynamic free area than a single-leaf smoke vent. Manufactured in a range of dimensions from 1600 × 1600 mm to 3000 × 3000 mm, in AWAK D (straight base) and AWAK DPS (straight-slanted base) types, equipped with two actuators-one per leaf. The vent complies with the EN 12101-2:2003 standard (CE 1488-CPR-0042/W) in classes Re 1000, SL 550/900, WL 1500, and B 300/B 600. It is designed for flat roofs with a pitch of up to 15° and can be configured to meet the requirements of individual projects.

Product Characteristics

Two leaves for a large aerodynamic free area

Simultaneous opening of both leaves provides a large effective smoke exhaust area, making the solution suitable where high smoke extraction performance is required.

Straight and slanted base variants

Available with a straight base or a slanted base adapted to the roof pitch. The supporting structure is designed to suit the roof construction and project requirements. Four segments of galvanized steel sheet with a minimum thickness of 1.25 mm, height from 300 to 1000 mm (standard 350, 500, and 750 mm). The AWAK D type has a straight base, while the AWAK DPS type has a straight-slanted base, adapted to the roof pitch. A supporting structure is required along the entire perimeter of the opening.

Wide range of cover options

Cellular polycarbonate 10, 16, 20, or 25 mm with a UV coating, NRO Kera Fire Protect panel 21, 27, or 33 mm in the BROOF(t1) fire resistance class, or single- and multi-layer domes made of acrylic or solid polycarbonate. Transparency: clear or opal covers selected according to the required daylighting effect, with optional Solar Control coating to reduce summer overheating.

Electric or Pneumatic operation

24VDC electric actuator with a current consumption of 2.0-8.0 A, or a pneumatic actuator powered by CO2 cartridges; in a double-leaf vent, two actuators are installed, one for each leaf. The leaf reaches the fire position is under 60 seconds.

Certified performance

Designed and manufactured in accordance with EN 12101-2:2003 - Re 1000 - 1000 cycles of the triggering system operation; SL 550/900 - reliability under a load of 550 or 900 N/m²; T(00); WL 1500 - resistance to a wind load of 1500 Pa; B 300/B 600 - resistance to temperatures of 300 °C and 600 °C. Declaration of Constancy of Performance CE 1488-CPR-0042/W.

Daily ventilation function

In the dual-function version, daily natural ventilation is provided as standard by a single actuator - one of the leaves is opened, which reduces operating costs while maintaining the full smoke exhaust function.

Equipment options and fire protection system integration

Fall protection grid, wind deflectors, and directional nozzles increasing the aerodynamic free area, painting of the inside of the base in RAL 9010, 9002, and 9003 colors, smoke control panel (Actulux, AFG), smoke detectors, and manual call points.

Manufacturer support and warranty

Up to a 10-year warranty on the polycarbonate cover and tightness, 2-3 years on the actuators, design of solutions for a specific facility, support with technical documentation, and technical advisory services.

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.

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 smoke 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 is installed or the pneumatic actuator is bi-directional. As a standard for a two-wing smoke damper, one actuator is used for the ventilation function (one of the wings is opened);
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.
