Window Fan Applications & Benefits

Many people, many flavours – please let in some fresh air!
Window fans can provide many benefits. In addition to regulating humidity and the indoor climate, they can be used to extract smoke and odours from the room. Ventilating fans can be particularly important in rooms like kitchens and bathrooms that particularly prone to excess moisture and odours.

In many cases opening a window is not desirable due to traffic noise or other issues. A window fan can provide convenient room ventilation while protecting the area from exterior noise and the outside elements. We offer a range of fans, accessories, and conversion kits to offer the ideal fan and fit or every type of window and room requirement.

Applications for Window Fans
  • Homes, flats & apartments: particularly important for damp rooms like the WC, bathroom, kitchen, utility room and cellar.
  • Hotel, restaurant and catering industry
  • Office, study
  • Darkroom and other hobby rooms sensitive to draughts
  • Greenhouse, conservatory
  • Gym, yoga studio
  • Rooms with limited floor space for thin panels and walls
  • Controlled ventilation
  • Ventilation with protection from burglaries and noise

Supply air considerations: to ensure the pressure inside the room stays in balance, the same amount of air must be supplied as is extracted. If there is limited air flow to the room from other sources (like louvres in doors or windows), consider purchasing a fan with reversible air flow to switch from extract to supply mode when needed.

When purchasing a window fan, it is important to select a fan that will move a sufficient quantity of air for the room. If you have any questions about the best fan to meet your needs, please contact us. Our expert staff would be happy to assist you.

There are many fan options available to provide good airflow including walls, window, duct and shafts fan designs. However, window fans have a few key advantages. They do not require ventilation shafts which means they can be fitted into old and new buildings. This makes them ideal for any premises with glass fronts or thin walls. Most models are constructed with a compact axial design making them easy to fit into small spaces. Our accessories also offer you the option to install window fans in sloping skylights or double-glazed windows.

Drawbacks of installation in a window
  • Limited options to install in rooms without windows
  • Landlord might forbid installation

Breakage of glass
Despite the recent trend: DIY is not always the best option.
Clear flat laminates or acrylic glass can be prepared with a jigsaw at home. If the fan needs to be fitted into a genuine glass, please contact a professional glazier or window fitter. Usually, the existing pane is replaced by a new pane with a corresponding opening for the ventilator.

The required electrical connection should be set up by an electrician.

Our tip: Check whether the window fan is compatible with your blinds and shutters before placing the order, you might have to switch to a flatter model. We also offer devices that can be mounted in a horizontal, vertical, or diagonal position.

Remote Controls, Sensors & Other Fan Accessories

Depending on the integrated equipment, window fans can be controlled manually or with motion, temperature, humidity, or smoke detectors. Automated models can be set to begin operating as soon as someone enters the room, once a certain humidity level or temperature is reached, or when the toilet is flushed or the light switch is used. If required, it is also possible to program the fan to continue running for a specific amount of time after it has been activated.

A self-regulating model is particularly recommended in the catering and hotel industry, as these fans can automatically turn on when needed. For example, the fan can be set to turn on automatically after detecting smoke from cooking food. In spacious rooms like cafeterias, it is possible to control several different window fans with the same speed controller, even if the fans are different makes or models.

Other available accessories include mounting kits in various sizes for glass panes with bigger thickness and different pane types. Furthermore, we offer airtight external covers with grilles that keep away large pollutants such as leaves. Those covers automatically close once the fan is turned off. This prevents cold air from infiltrating indoors. A corresponding filter holds back smaller particles like dust and dirt, even if you operate the fan in the reversible supply air mode.
