If you have recently repaired your home, you probably faced the problem how to choose the right bathroom fan.
The ventilation is needed not only to exhaust the air but also to eliminate the steam, formed in bath. Using the vent, the bathroom fan exhausts air and prevents condensation and mold in the premise. If the bathroom doesn’t have a window, you should look for an alternative solution. The most frequent solution in the modern homes is the axial fan with electrical power.
Its main feature is the air flow volume. According to the Bulgarian law, the required air flow volume is 90m3/h for bathroom fans, 90m3/h for toilet fans and 90m3/h for laundry room fans.
The air flow of the fan can be also calculated as a function of the premise volume and air renewal. The air renewal represents the number of air exchanges in the premise per hour. The recommended renewals for bathroom are 5 times per hour and for toilet – 7.
Selecting the place where the fan will be mounted in the bathroom is also very important. It is recommended to install the fan in the farthest point of the premise from where the fresh air is coming from, in order to achieve the optimal air exchange and ventilation in the premise. If your bathroom is bigger we recommend instead of one powerful fan to mount two with lower capacity, and one of them to be situated above the bathtub or the shower because this will provide better air exchange and prevention of moisture.
Do not forget that the extract air from the bathroom or toilet should be compensated. The tendency in the last few years is from doors and windows to pass less air and to be very tight. We recommend you mounting a small transfer grill in the door to pass the required air.
It is also recommended the chosen fan to have a back draft shutter. This shutter will prevent the entering of odors and smells from air ducts and also prevent warm leakage of air through the fan.
