If you’ve ever forgotten about damp clothes in the washing machine or smelt your dog when they’ve just come in from a walk, you’ll know the scent we’re talking about.
#EXTRACTOR FAN FOR SHOWER SKIN#
Even if you don’t have any respiratory conditions, the allergens that it produces can cause symptoms like sneezing, coughing and skin rashes. Mould can be a health hazard for those with respiratory problems, such as asthma. Once it’s started to grow, it can be really tough to remove. You may find black mould in the grout between your tiles or sealant around the bath and sink. Mould particularly likes warm and damp environments, making the bathroom the perfect breeding ground. If the moisture in your bathroom that we’ve mentioned above has nowhere to go, mould will begin to grow.
An extractor fan will pull this steam out of the room. If this steam is left to linger in the room without being expelled, excess moisture and condensation will build up. As you run the hot water, some of it evaporates and creates steam. The main job of an extractor fan is to remove the humidity that builds up inside a bathroom when the bath or shower is running. So this would be 268.80 divided by 3.6, which equals 74.67 l/s.Īs we’ve stated above, unless you have an openable window, a bathroom fan is required under building regulations, but what else can they be good for? Therefore, to find the l/s from your extraction rate, divide it by 3.6. If you’re struggling to find the extraction rate, you may need to look out for a litres per second (l/s) measurement.
Use the extractor rate to determine whether the fan will be sufficient or if you need a more powerful one. When it comes to purchasing a new extractor fan, you will usually be provided with the diameter in millimetres, the extractor rate and the power voltage supply. In our example, this would be 26.88 by 10, which equals 268.80 m^3/hr. Therefore, take the volume of your bathroom that you’ve just calculated and multiply it by 10. It’s recommended that a bathroom has an air change per hour (ACH), often referred to as an air change rate, of 10. For instance, say that your bathroom has a height of 2.8 metres, a width of 3.2 metres and a length of 3 metres, multiply 2.8 by 3.2 by 3, which gives you 26.88 m^3.Īir change is a measurement that determines that amount of air that should be removed from a room per hour. Once you have this information, multiply the three figures together to get the size in cubic metres. Do this using a measuring tape by noting down the height, width and length of the room in metres. Some of them can be found below.To work out the extraction rate, you need to calculate the cubic metres of the room you want the fan to go in. In order to calculate the volume of the room, use a simple formula please: Volume (cub.m.)=length*height*width (m).įor different premises there are different norms for air exchange. Volume of the room and air exchange per hour.Īlong with the above mentioned, the following should be taken into consideration when choosing a fan:.Diameter of the flange that can be installed into your ventilation shaft – 100, 125 or 150 mm.For kitchen or other premises you can use a fan with pull-cord switch for short-term air extraction. Humidity sensor will turn the fan on when the level of moisture exceeds the set one. If the fan is set in the bathroom or lavatory, it is quite possible that you will need a timer that makes the fan operate and turns it off automatically even after you have left the room. You can choose from white ceiling vents, chrome diffusers, or LED light kits.įan choice and air circulation calculationīefore choosing a fan define its destination, necessary modifications and, what is important, the power (capacity) of the device. The kits are purposely designed to include all items for a ducted vent system installed in bathrooms, shower rooms, toilets, en-suites, wet & utility rooms.įor smaller or lower noise systems choose Ducto with its rubber motor mountings or Turbo for larger bathrooms, power showers, or quicker extraction of condensation. We have combined all essential popular selling ventilation items into four contractor kits.
