Silent Dual 100

Dual Sensing

The fan operates automatically when it detects movement (via the PIR) or rises in humidity levels and activates a pre-set mode to achieve the lowest energy consumption and the lowest noise level.

Dual Speed: Intermittent or Continuous

SILENT DUAL 100 provides optimum versatility to be programmed as either an intermittent or continuous running fan. In intermittent mode the fan starts automatically when it detects a slow increase in humidity. As humidity rises and falls, the motor speed tracks the humidity in direct correlation until the humidity level has fallen below the set threshold, ensuring quiet and efficient operation. In intermittent mode, the fan also automatically starts (75% of the maximum speed) when movement is detected and will continue to operate for the set period selected by the adjustable ‘run-on’ timer. There are two setting available for the over-run timer: 2 minutes (for bathrooms less than 4m2) and 15 minutes (for bathrooms over 4m2).

In continuous running mode, the motor speed operates the same as intermittent, however instead of coming to a complete stop, the fan continues to operate on trickle speed (43% of maximum speed).

Dual Inlets

The SILENT DUAL 100 has dual inlets for enhanced aerodynamic performance. Air is directed via the front and side panels, achieving similar performance to a traditional front grille but in a stylish and slim-line design to deliver greater pressure at low flow rates.

Intelligence & Efficiency

The SILENT DUAL 100 incorporates an intelligent algorithm to automatically adjust its settings according to the environmental conditions, without the need for user interaction. The motor is commissioned to achieve the required flow rate, minimising the electricity consumption and noise levels to meet the exact ventilation requirement.
