Wall Mounted Ventilation Fans

Choosing the right ventilation fans to install in your home is often decided by where your duct system is located. While many homes have ceiling ventilation fans, some have wall fans, and if you need a replacement then you will likely need to purchase wall mounted ventilation fans (to avoid having to build a new duct system or rearrange the one that you already have). Wall mounted fans are available in many different sizes and strengths, and there are a number of things that you will need to do to determine the type of wall mounted ventilation fans to use within a particular area.

Installing wall ventilation fans

Wall ventilation fans are usually quite easy to install. This is especially true if you just need a replacement fan and do not have to modify the existing duct work in any way. The installation of wall mounted ventilation fans can often be done at home on your own, but it is also possible to acquire the installation services of a professional.

Different types of wall mounted ventilation fans

• Commercial wall mounted ventilation fans are often hooked up to a centrifugal fan that provides ventilation and exhaustion throughout a large area with multiple exhaust points.
• Wall mounted ventilation fans for home use are typically single-unit fans. They are often located in kitchens and bathrooms, but can also be built into the attic area or even bedrooms. Most of these fans are quite small and typically have lower CFM than wall mounted ventilation fans used for commercial and industrial areas. For those concerned about noise production, Panasonic offers a range of quiet fans known as Whisper. Other manufacturers of excellent wall ventilation fans include Broan, NuTone, and AirKing
• Industrial wall mounted ventilation fans are usually a lot more powerful than the other types. This is because they are required to exhaust a considerable amount of noxious or contaminated air.

CFM for wall mounted ventilation fans

You will likely need to determine the strength of wall mounted ventilation fans. The way to figure this out is to calculate the area of the room in which you plan to mount the ventilation fan. Every ventilation fan has a specific potency measured in CFM, which means cubic feet per minute. A fan that has a higher CFM will be capable of displacing more air than one with lower CFM.

ACH for wall mounted ventilation fans

Figure out the air changes per hour (ACH) required for the room in which you need to install your wall mounted ventilation fans. The larger the room, the more air changes per hour be required to provide the right level of ventilation. Bathrooms and kitchens will require more air changes per hour than most other rooms in your household, even if they are smaller. This is because kitchen and bathroom areas need more ventilation because of higher levels of humidity or gases produced from cooking. Of course, the ventilation system does not need to be functioning at all times within either the bathroom or the kitchen, but when it is working it should be performing at a higher level than other areas.
