Bifurcated Fan Section

Bifurcated Fan Section

It has a belt along with Pulley, Bearing, Motor which are kept outside the airstream. So that it do not come in Contact with the smoke.

Application of Smoke Spill Fan Section

  • Kitchen Ventilation: Kitchens are prone to grease fires and other cooking-related hazards. Smoke spill fans are often installed as part of the kitchen exhaust system to help remove smoke and grease-laden air in the event of a fire. These fans play a critical role in containing smoke and preventing it from spreading to other parts of the building, reducing the risk of fire damage and facilitating safe evacuation.
  • Smoke Control Systems: Smoke spill fans are integral components of smoke control systems installed in large buildings such as shopping malls, airports, office buildings, and high-rise structures. These fans help prevent the spread of smoke to other areas of the building, keeping escape routes clear and improving visibility for occupants and firefighters.
  • Stairwell Pressurization: Smoke spill fans are often used in conjunction with stairwell pressurization systems. By pressurizing stairwells with clean air from the outside, these fans help prevent smoke from entering stairwells, which are crucial escape routes during a fire. This allows occupants to safely evacuate the building without encountering smoke-filled stairwells.
  • Atrium Smoke Control: In buildings with large atriums or open spaces, smoke spill fans are used to control the movement of smoke in these areas. By directing smoke towards designated exhaust points, these fans help maintain tenable conditions in atrium spaces, allowing occupants to evacuate safely and facilitating firefighting operations. 
  • Smoke Extraction: Smoke spill fans are utilized for extracting smoke from specific areas within a building, such as underground parking garages, mechanical rooms, or other enclosed spaces where smoke accumulation can pose a significant hazard. These fans help remove smoke from the environment, improving visibility and reducing the risk of smoke inhalation for occupants and emergency responders.
  • Building Code Compliance: Many building codes and fire safety regulations require the installation of smoke control systems, including smoke spill fans, in commercial and residential buildings above a certain size or occupancy capacity. These systems help ensure compliance with regulatory requirements and enhance the overall safety of the building in the event of a fire.

Feature:

  • Smoke Extraction Capability: This could involve the ability to quickly switch to a higher ventilation mode to help clear smoke from an area in case of a spill or fire.
  • Smoke Detection Integration: Integration with smoke detection systems can be crucial. Belt-driven fan sections might have sensors that detect smoke, triggering automatic responses such as increased ventilation or activation of smoke extraction systems.
