Emergency Smoke Extract LCA JTHT SMOKEX


    • Axial impulse fans suitable for installation in underground car parks and/or tunnels. They have been designed and certified for the handling of smoke and hot gases caused by fire. These fans are dual purpose, i.e. they provide both normal ventilation (carbon monoxide removal) and smoke control in case of fire.
    • In the standard configuration for normal ventilation (CO extract), the range can be used up to a temperature of +60°C. The fire/smoke extraction models (HT) are CE certified to class F300 or F400, and guaranteed to operate at 300°C for two hours in compliance with Standard EN12101-3 by the Applus laboratories in Barcelona.
    • The special impulse induction fan technology represents the most innovative and cost-effective alternative to traditional ducted mechanical extraction systems. There is a drastic reduction in the cost of installation (no need for ducted and grilled systems) and considerable running cost savings (the same fan controls polluted air and smoke and hot gases). Additionally, it is possible for sections of the system to operate only when the need arises (with other sections of the system not operating).
