TECHNICAL INFORMATION ON

DC BRUSHLESS MOTOR CEILING FAN

Our DC fans can be operated in summer for a cooling effect and reversed in winter to re-circulate warm air trapped at ceiling level.

The DC fan motors are of silicon steel construction with double sealed bearings, ensuring long, quiet, reliable and maintenance-free operation. The motor housings are of metal or wood construction. All metal surfaces are powder coated or plated and lacquered to give a permanent seal and prevent tarnishing.

All models operate on 110-220 Volt/50 cycle electricity supply. The power rating of our fan motors range from 60 – 75 watts with 3 forward and 3 reverse speeds. Fan running costs are less than running a 100w light bulb for the same period.

Installing this fan is similar to installing a light fitting but you must ensure that the fan blade tips are at least 7” (18cm) from any obstruction such as a sloping roof or beam. Blades should be mounted at least 7ft 6” (2.3m) from the floor.

Ceiling fans can be installed in any room, except bathrooms. In conservatories or rooms with higher ceilings a drop rod and conversion kit may be required. Wall controls and remote controls are also available.

DC MOTOR

The addition of the DC motor fan to our range demonstrates our commitment to developing efficient, effective fans. Our unique control system takes your household power supply and converts this to a low voltage supply for the windings.

The ‘Brushless’ DC (BLDC) motor has permanent magnets which respond to the varying DC signals from the control system that in turn generates the motion required of a fan. This means lower heat dissipation, quieter operation and lower magnetic interference.

A greater degree of speed control can be applied to DC motors and it offers 6 forward and 6 reverse speeds; twice that of a normal fan.

ENVIRONMENT

Protection of the environment in which we live and operate is part of our values and principles. We consider care for the environment as one of our key responsibilities and an important part of the way in which we do business.

We are energy conscious when looking for developing new product and are at the forefront of environmentally friendly product development, introducing a DC motor fan for 2010 that uses 60% less power consumption than a standard fan.

The winter setting on our ceiling fans re-circulates warm air trapped at ceiling level, eliminating cold spots and draughts and distributing room heat without creating a cooling draft. Used correctly, a fan can save as much as 10% on energy bills during winter months.
