London, United Kingdom (PressExposure) March 02, 2012 -- It used to be that the extractor fans we put in our homes were extremely limited. If you could not go from an interior wall to the outside in a direct route, you could not use them because they did not have the power to pull or push air through a longer duct system. If your exterior wall ran through a wet wall or other obstacle, you were simply out of luck. Now, fans use either centrifugal force to create stronger suction or an in-line fan somewhere between the unit and the exterior of your home to create stronger flow. Today's extractors are much more versatile.
- Powerful central units can handle flow from several points in your home
- Remote control for speed and direction
- Constant flow with short bursts when needed in multiple rooms
One Central Unit for Multiple Locations
One of the most popular options when installing extractor ventilation in homes with multiple units is a central unit located in a basement or attic. The unit, which runs on a very slow constant flow, can be activated from any location for that room only, allowing a burst of flow to clear that room's air of odours. These units can be expensive but are worth it because of the singular installation and power saving motors. This type of unit is perfect for large homes that would otherwise require multiple single unit installations.
One Unit with Two Motors
Smaller homes with interior bathrooms far from an exterior wall require long lengths of duct work that can decrease a unit's efficiency. This usually required a second strong fan motor somewhere between the unit and the exterior to boost the flow through the duct work. Now, powerful motors use centrifugal technology to increase flow over distance. The longer the distance, the more powerful the motor required to be effective. Automatic sensors can detect fluctuations in air quality due to humidity changes, turning the fan on when needed.
Sensors Detect Human Presence
Sensors that detect changes in humidity can be set to detect major changes only, like when someone takes a long hot shower, or be so sensitive as to be activated by human presence in a closed room for more than a minute. If someone uses the bathroom and is in the room for more than 60 seconds, their body heat would activate a strong reverse flow, clearing the room of odours. Some units activate a spray to scent the air as well.
Technology Marches On
Extractor fans have come a long way from the days of simple motors in rooms near exterior walls. The technology is so advanced that the smallest changes in humidity can activate a motor either in the unit or a central unit elsewhere in the house. Powerful motors run efficiently and have little effect on electric bills. These units have become so powerful that they can be used in bathrooms and kitchens in large, commercial properties and still be very effective. Motors using ball bearing technology and centrifugal force can run for tens of thousands of hours providing years of service. Who knows where the technology will go from here?
