Bathroom Exhaust Fan – An air extractor is an appliance designing to suck and renew the air of a room. It is composed of a fan connecting to a motor that transfers the movement. It has two main functions: Like dehumidifying appliances, remove excess moisture that can lead to deterioration of the paint. And then appearance of mold and fight bad odors. There are two types of bathroom exhaust fan fundamentally, depending on the type of fan: Axial fan exhaust. The air flow passes through the fan parallel to its axis.
Centrifugal fan exhaust. In this type of exhaust, the air flow at the inlet follows the direction of the axis but the outlet is perpendicular to it. When choosing a bathroom exhaust fan for your home. You will have to take into account some characteristics to choose the most suitable. The maximum volume of air sucked: the suction capacity of the exhaust must be proportional to the size of the room. For rooms up to 30 m3 (12 m2 x 2.5 meters in height) an extraction capacity of 75 m3 / h. Will suffice (in a little more than 20 minutes the whole air of the room would be renew). Sound level: it is necessary to have in count that the apparatus is not too noisy.
A sound level above 40 decibels is adequate. Anti-vibration mounts on the motor will prevent the generation of noise and vibrations. Another system that helps to avoid the turbulence and reduce the sound level is the diffusers. Energy consumption: they are small devices. So the consumption is not very high. For small kitchen and bathroom models, they are usually about 30 w. Exhaust outlet tube outlet diameter. The most common measures are 100 or 110 mm. If we are going to replace an existing one or place it in the area of the existing ventilation grid. Check that the diameter of the bathroom exhaust fan is adequate. The degree of protection IP: it is necessary that the air exhaust is water resistant since it will be place in a wet room.
The degree of IP protection must be the IPx4 minimum to support water splashes. Humidistat: one of the interesting features is that the bathroom exhaust fan has a humidity detection system and can be programming to start automatically if the humidity of the room exceeds that fixed by the user. Other features: other additional features that may be interesting are models that have light or incorporate the function of heating the air. If we choose the bathroom ceiling and we will take advantage of the location of the ventilation grid, the process is simple.
