Ducting

An extractor fans extracts the air in the bathroom or kitchen, ventilating it, to remove damp or moisture in a room, therefore reducing the humidity level. 

Do not put your fan in the dishwasher; cleaning it with a clean cloth will do. See the instructions of the specific extractor fan. 

The job of an extractor fan is to eliminate excess moisture in the air, which in turn removes condensation, keeping your home well-ventilated. 

See the specifications for each fan; there is a way to calculate the volume of your bathroom and the usage, and based on this, you can choose from a wide range of bathroom fans. 

The min. extractor rate for an intermittent kitchen fan depends on the location of the fan; next to the hob it should be min. 108m3/h (30l/s) and otherwise 216m3/h (60l/s). Ventilation rates for continuous extract fans differ from intermittent fans and differ on the size of the dwelling and room type.

There's no "one size fits all" in the case of fitting a bathroom fan; you need to know all your requiremtns including the best location for the fan (wall, ceiling, inline), grill, roof vent, soffit, etc. It is best to get a specialist to specify, or you can replace a fan like-for-like.

It is recommended to have a bathroom extractor fan in a bathroom with a window. Opening the window can help reduce the amont of moist air, but doesn't provide the same level of airflow to the exterior of the house that a fan would. 

An extractor fans always needs to vent to the exterior of the building, otherwise the moist air it removes from one place will be deposited elsewhere to create condensation or dampness.

No, we at Sparks only sell extractor fans; we cannot advise what you need nor can we install these in your property.
