Shower Extractor Fans

Extractor fansare some must-have in every home where they help to eliminate the condensation of two main parts that question - bathrooms and kitchens. Mounting the hood right help remove excess moisture caused by activities such as showering and cooking.

The two main types of extractor for home use are the axial and centrifugal. Theses can be wall, window or ceiling and there are many different models to choose from and with different characteristics.

The effectiveness of an exhaust fan is measured by its rate of air flow, which is the number of complete air changes within the room per hour. Generally, a kitchen requires 10-15 and a bathroom 6-8 times per hour.

Thecapacity a fan is defined as the volume in cubic meters (m³), or cubic feet (ft ³) per hour. To determine the minimum capacity of exhaust fan needed, you will need to calculate the room volume (length x width x height), then multiply that number by the recommended number of air changes required. So, a kitchen measuring 15 cubic meters (3m long x 2m wide x 2.5 m high) and require 10 air will need a fan capable of extracting at 150m ³ per hour.

Many extractors have timers that allow the product to continue working even after turning it off. The idea behind this is that when you leave the bathroom, the fan continues to extract steam and turns off automatically after 10 minutes, which saves you from having to go to the bathroom to turn it off.

Advance features are sensors that turn the fan when the humidity in a room reaches a predetermined level. Others are fired up by motion sensors integral body. When motion is detected, the fan runs for a preset time. Any other movement restarts the sequence.

The noise level of an exhaust fan is also something to consider. This is measured by sound pressure level in decibels at three feet. One of the quietest models on the market is listed as operating at 26.5 dB (A) 3m.

Internal extractors can vary in price from less than 15 pounds to over 100 pounds.
