        Energysaver™ Sensamatic Kitchen Fan SMES150
a
 

Energysaver™ Sensamatic, fully automatic 150mm (6") axial kitchen fan, with integral microprocessor controlled contamination proof humidity sensor, together with 240V to 12V Switching Power Supply situated within the fan – no transformer required.

The energy efficient, ball bearing 12V DC motor only requires 8.4 watts of power when running, resulting in a long and trouble free operational life whilst reducing energy costs to the Resident.

Under the control of a microprocessor, the sensor monitors continuously the Relative Humidity (RH) in the room. If there is a sudden rise in RH the sensor anticipates hitting the set point and activates the fan before it is reached. After the fan has reduced the RH to about 5% below the preset set point, the fan switches off. When the fan is running under sensor and microprocessor control the L.E.D. flashes.

a Construction
Formed from a high quality impact resistant white, thermoplastic material. The silent operation shutters open automatically when the fan switches on, and again, close automatically when fan switches off to prevent back draught through the fan when not operating.

Motor
A 12V DC brushless, electrically commutated sealed for life lubricated ball bearing motor. The motor incorporates an overload protection device and conforms to EEC Directive 78-889 for radio interference. The motor will operate in temperatures up to 40°C. The fan conforms to BS3456, BS800 and BS5490. The incoming AC 240V supply is converted to 12V DC by an integral switching power supply. The 12V DC motor, which consumes only 8.4 watts, requires no separate transformer.

Installation
For best effect, the extract fan should be fitted at a minimum of 2 metres from floor level (where possible), but not closer than one metre to a major moisture producing source. The unit should not be fitted immediately above a cooker – a remote sensor should be used in this application, order code SMES150/REM/W150.

Care must be taken if the fan is fitted in a room containing a fuel burning device without a balanced flue. There must be sufficient air replacement to prevent ‘spillage’.In many instances, a passive air vent or an air brick, may need to be fitted to other cooler rooms within the property in order to promote a good airflow throughout the dwelling.


Fitting Kits available:
WALL:
Comprises wall sleeve and external grille (available in brown, terracotta, buff or white)
WINDOW: Mounting unit suitable for S/G or D/G windows. (for greater efficiency we would recommend that a fan and remote sensor configuration of this model be used for this application, order code SMES150/REM/W150)
CEILING: Ceiling ring available for fitting into plasterboard. 150mm dia. ducting will be required. We only recommend that this axial fan be ducted a maximum 1.5 metres. For greater distances, a centrifugal or mixed flow type unit would be more appropriate. (see Centramatic and remote sensors data sheets)
