The VT1400 is the largest fan of its type in the local market place.
The VT1400 is the largest fan of its type in the local market place and boasts a 1400mm (55") impeller with blades manufactured from durable and corrosion resistant aircraft grade aluminium.
It is electronically balanced for optimal vibration-free operation.
The impeller blades are of low noise design and self cleaning, requiring a minimum of power input.
Made from aluminium, the impeller blades and the v-belt pulley prevent electrolysis between dissimilar metals (galvanised blades may corrode heavily in humid conditions if in contact with aluminium).
A long-life v-belt transmits power from the electric motor to the impeller and a spring-loaded belt tensioner ensures even belt tension, implying a minimum of maintenance.
Large diameter die-cast aluminium pulleys ensure optimal grip for the v-belt and an extremely long service life for the bearings and other rotating components.
The main impeller bearing is a high quality permanently sealed double row ball bearing with a service life of many years.
The frame or side plates and venture around the impeller are made from durable galvanised sheet metal.
The side plates are equipped with M8 clinch nuts to allow easy mounting of the fan units.
The automatic louvers are made from durable galvanised sheet metal.
The louvers pivot in plastic bushes and are opened by air pressure as the fan starts up, kept in the fully opened position by a set of counter balances, ensuring minimum system drag and frictional losses.
The louvers close positively when the impeller is not running.
