Running wheel
is axial, moulded from sheet steel, with three performance-optimised blades. The surface finish is grey epoxy paint RAL9002.
Motor
is asynchronous with short armature, with a large number of poles to achieve the required speed. It is designed for continuous operation. The maximum operating ambient temperature is 40 °C. The motor has sealed ball bearings with grease packing for life. The motor has overload protection built into the winding. Insulation class B. IPX0 protection.
Square box
It is accessible by removing the cable cover, which slides along the hanging bar. Connection is by cable under plaster or on plaster. The terminal block contains a relief clip to prevent the cable from being pulled out.
Speed control
Three-stage control using the controller included in the delivery. Can be changed direction of rotation using a switch on the fan motor. A wireless control is also available as an option.
Mounting
is done by hanging from the ceiling or other structure. The hanging device must be sufficiently dimensioned, both in terms of static and possible dynamic loads. The bottom edge of the fan must be positioned so high that persons in the vicinity of the rotating impeller cannot be endangered. The minimum recommended distance from the floor is 2,5 m. When installing multiple fans, the impeller blades of each fan must not be interchanged. The blades are balanced for each unit separately.
Accessories
- Speed controller included
- HTB RC KIT wireless controller with adjustable 1/3/6 hour timing
- HIG/HYG room hygrostats
- RTR 6721 room thermostat
Instructions
The fans are particularly suitable for ventilating large areas such as industrial halls, pubs, hotels, sports halls, offices, libraries, study rooms and departure halls due to their robust construction. By permanently ventilating high spaces with a significant temperature differential between floor and ceiling, spatial temperature equalization can be achieved in the winter, thereby significantly reducing energy consumption and heating costs. In these cases, differential thermostats with two sensors can be used advantageously, which switch on a fan at a set temperature difference to mix the warm and cold air zones.
Warning
The fan anchorage should be checked regularly. The inspection period must be specified in the user's operating instructions.
