Dynair CC-JD LP HT Axial impulse fans

The CC-JD LP HT series of axial impulse fans are suitable for installation in underground car parks, or tunnels. These devices are specifically designed and certified for extraction of smoke and hot gases in case of fire. These are “dual purpose” fans, meaning they can provide both normal ventilation (carbon monoxide removal) and smoke extraction in case of fire. Their octagonal shape and extreme compactness, combined with their low profile allow for easy installation even in garages with strict height limitations.  These fans can be used for CO extraction up to +50°C in continuous operation, and are CE certified for F300/120 and F400 standards by the independent APPLUS committee, according to EN12101-3:2015 regulations.
