Smoke estraction and ventilation
VENTS, established in the 1990s, is a leading company in the ventilation industry, exporting to over 90 countries. The company focuses on research and development, quality control, and environmental protection, adhering to ISO 9001:2000 standards. VENTS is a member of several international HVAC organizations.
Smoke control systems are essential for fire safety, facilitating safe evacuation by extracting smoke and preventing its spread. These systems are integrated during the building's construction phase and must comply with construction standards. Key components include smoke exhaust fans, smoke dampers, fire-resisting dampers, and pressurization fans.
These fans are used in emergency systems to remove smoke and hot gases, capable of handling temperatures up to 600°C for 120 minutes. They are made of heat-resistant steel and available with horizontal or vertical air discharge.
- Fan Series VKDV/VKDH: Designed for smoke removal with vertical or horizontal air discharge. Available in various impeller diameters (630 to 1100 mm) and power capacities (1.5 to 37 kW). Maximum air temperature handling is 600°C. Motor ingress protection rating is IP 54.
- Fan Series VKT: Specifically for fireplaces, with air capacity up to 1000 m3/h. Handles smoke fume temperatures up to 400°C. Equipped with a single-phase motor and sound pressure level of 52 dB(A).
- Damper Series KPD/KPDU: Fire safety dampers with a fire resistance rating of 180 minutes at 600°C. Available with single or multiple louvres and various actuator types (electromagnet or Belimo actuator).
- Fans are made of galvanized steel with a polymer coating for durability against weather and aggressive environments. They include protective grilles and backward-curved blades to minimize soot deposits.
- Dampers are constructed from 1.5 mm thick galvanized steel and are available in wall or duct-mounted variants. They feature manual and automatic control options.
- Fans should be mounted on roofs with adequate space for maintenance. They require connection to power mains via a speed controller for optimal operation.
- Dampers should not be installed in explosive or highly flammable environments. They must be regularly cleaned to prevent flammable deposits.
- Fans are suitable for extracting smoke from fireplaces, furnaces, and hearths, as well as for standard ventilation purposes.
- Dampers are used in smoke control systems to extract combustion products and support evacuation during fires.
The document describes single-flange and double-flange variants of KPDU and KPD dampers. Dampers can be equipped with internal or external Belimo electric actuators or electromagnets, available in 230V or 24V options.
Guidelines for installing dampers in vertical and horizontal building structures are provided, emphasizing the importance of selecting the correct BxH cross-section damper based on spatial orientation.
KP-1 series dampers are designed to resist fire for at least 60 minutes at 600°C. They can be equipped with mechanical actuating units with thermal fuses and return springs or electric actuators with built-in return springs and thermal breakers.
The document provides detailed specifications for various damper models, including dimensions, weights, and flow area data. It also includes technical specifications for electric actuators, such as rated voltage, power input, torque, and swing time.
Fire-resisting dampers must comply with applicable standards, ensuring the seal's fire resistance matches the building envelope. A minimum access space of 350 mm is required, and inspection holes must be arranged.

Smoke control is a complex process involving smoke extraction and fresh air supply by the supply and extract ventilation system of buildings in order to ensure safe evacuation of people in case of a fire in any of the spaces. The smoke control system of a building or structure must ensure protection of people along the evacuation paths from the fire hazards during the time required for the personnel evacuation procedure or the entire period of fire development and control by means of extracting the combustion and thermal decomposition products and/or preventing their spreading. A smoke control...

Smoke control system functions: Prevention of smoke spreading from the ignition source. Prevention of smoke transfer to the evacuation paths (maintaining acceptable conditions for the people being evacuated from the building). Maintaining a microclimate beyond the ignition source area to enable normal operation of fire-fighting teams. Protecting the life of people in the building. Protecting the property against damage. The smoke control system elements are integrated at the initial phase of the building (residential complex, office block, warehouse facility etc.) construction. These communications...
