Large Flow Fan

To prevent the flames and smoke spreading in large structures, such as parking garages, airports, aircraft on the ground, subways and rail and road tunnels, LEADER has produced the Easy 4000 large flow ventilation unit, which enables 3000 square metres to be blown in just 30 seconds. Also, during the smoke extraction in a one-kilometre, double-track tunnel, smoke was cleared in 12 minutes bringing sufficient visibility to enable firefighters to enter. The tunnel was completely cleared within 20 minutes. The Easy 4000 can also help to rapidly reduce the concentration of CO and, in the right conditions, allow operations to continue without the need for SCBA.

The Easy 4000 has a four-stroke BMW Flat Twin engine with an electronic start-up that gives a powerful airflow of 400,000 cubic-metres-an-hour in the open air. The extremely low weight of the Easy 4000 gives them what Leader describes as: “an unrivalled performance/manoeuvrability ratio in operation, meaning just one or two firefighters can handle them easily.” Equipped with a nozzle spraying system in the standard version, Leader large flow fans offer effective gas dilution, dissipation or displacement and smoke cooling.

In addition to the light-weight trailer version, the fans are available in a skid version for attachment to an operational vehicle, truck or trailer. Other options are also available such as 360 degree manual rotation system, 600 mm or 1200 mm elevating platforms, flexible exhaust gas extensions, and blowing ducts.
