Use ducted fans, through-wall fans or window fans at all times. DO NOT use ceiling fans which discharge into the ceiling cavity, this only moves the problem. Fresh air in Moisture will permeate insulation and ceiling linings causing further problems. In particular with bathrooms air drawn from an adjacent bedroom or hallway, in turn, think in terms of “room-conditioning”. Warm, moist drawn from an open window or door. air is immediately attracted to cold surfaces, where it condenses into water droplets. This ensures that fresh air is being drawn into the entire house at regular periods. Switching the fan on before Cold surfaces include glass, mirrors, tiles, wet-wall starting showering or cooking sets up effective air-fl ows linings, cold un-insulated ceiling linings, etc. before condensation problems occur. You cannot remove all of this air at a rate fast enough Closing doors to adjacent living areas assists in stopping to stop this happening and if you could, you would be the transfer of moisture to those areas but ensure standing in a wind tunnel. Use of a bathroom heater to that suffi cient air can enter under the door to replace warm the room prior to use greatly assists in reducing extracted air. Use a door vent if necessary. condensation. For a fan to remove air effectively, the same amount of air FAN PLACEMENT being extracted must be able to enter the room, e.g. air in = air out. An air-tight room will mean no air movement. If Careful location of an extraction fan will ensure the room is tightly sealed (e.g. a tight-fi tting door, with no maximum air-fl ow through the room. Air extracted gap at the bottom), you may need to fi t a through-door grille to from a bathroom, for example, can be replaced with dry allow replacement air into the room. Window Closed Poor Circulation Medium Circulation Window Closed “Makeup air” is required for the fan to function effi ciently. This is simply air that replaces the air that has already been extracted and can be achieved with a gap under the door (min 5mm) or a grill in the door, we do not recommend opening a window.

Always use the l/s x 3.6 = m³/hr. (e.g. 25 l/s x 3.6 = 90m³/hr). higher limit. • The result is the total performance required in cubic If you know the Cubic Metres/Hour (m³/hr): metres per hour. m³/hr ÷ 3.6 = l/s. (e.g. 200m³/hr ÷ 3.6 = 55.55 l/s). Select a fan with a higher performance than this fi gure. Example: Note: What is the best fan for a bathroom that is 2.8m long Stated extraction rates are “free air” values and do by 2.8m wide with a ceiling height of 2.4m? not account for grille type or duct run restrictions. • Calculate the volume of the bathroom: 2.8 x 2.8 x 2.4 = 18.8m3. • 11-15 air changes per hour are recommended for a bathroom. Multiply the room volume by 15: 18.8m3 AIR CHANGES PER HOUR (ACH) x 15 = 282m3/hr. The number of times the total room volume of air is changed • The fan to choose for this bathroom would be a fan each hour. Refer to the table below for the recommended Air that performs at greater than 282m3/hr. Changes per hour based on the room type. • A fan that has a performance level of 313m3/hr or higher (e.g. XP150, or SF150) would do this job.
