The yellow duct is designed for use with fans without Ex protection and is suitable for conventional ventilation and smoke extraction tasks in fire service and industrial environments. It is used for positive pressure ventilation of buildings, smoke extraction after fires, and for supplying fresh air to shafts and basements.

In combination with our fans, it can also be used for light foam generation, expanding tactical operational capabilities.

The black duct was developed for applications with increased safety requirements and is particularly intended for use with TYPHOON Ex-Fans. It is suitable for hazardous areas, supports the discharge of electrostatic charges, and is used for gas extraction and smoke removal in ATEX zones and sensitive industrial environments.

It can also be combined with all other TYPHOON fans and provides additional safety reserves.
