Through The Wall Exhaust Fans or Thru Wall Mount Fans can be the answer to your air movement problems. Using wall exhaust fans and or wall air supply intake fans can be a lower cost solution to controlling the temperature and air quality for a safer and more productive work environment. Most wall exhaust fans come in either belt drive or direct drive. The belt drive version is typically used for areas that require more CFM or to accommodate higher static pressures. They are most often quieter on the decibel level scale as well. The direct drive version is usually a less expensive solution, requiring less maintenance since there is no belt to replace.
The Shutter Mounted Wall Exhaust Fans are a great all-in-one solution for removing heat, stale or stagnant air, fumes and dust, while helping to draw fresh clean air in to your warehouse, shop, garage, or other work space. Depending on your electrical system, the shutter mounted wall exhaust fan is offered as either a 1 or 3 Phase, 115, 208, 230 or 460 volt versions. Since these wall exhaust fans come with the shutters attached, there is no need to purchase the shutters separately. We do however offer other accessories such as: variable speed controls, rheostats, 2 speed switches, thermostats both 1 and 2 stage, all weather hoods for protection against driving winds and rain, gravity or mechanical intake and exhaust shutters and dampers.
Cabinet Mounted Wall Exhaust Fans unlike most of the shutter mounted fans, are exhaust fans that are encased within a box type cabinet for deeper or thicker thru-wall applications. While offering a different wall mounting option, these fans still serve the same purpose of exhausting or removing hot, stale and or contaminated air from the work space. These fans typically do not have the shutters or dampers built in or attached to the fan assembly itself. In many cases the shutter is mounted on the outside wall of the building or structure when using this type of exhaust fan.
Panel Mounted Wall Exhaust Fans tend to be used in areas where space availability is at a premium. The contractor will usually build a framing system on the wall for these fans to be mounted to. Again, the shutter / damper is most often mounted to the exterior of the building in these cases. Like most all exhaust fans, these are also available in belt drive or direct drive, and offer multiple voltage choices in either 1 or 3 phase versions.
Using a Motorized Impeller Wall Exhaust Fan is an economical and efficient way to cool electronic storage cabinets. These motorized axial fans are the perfect solution for providing high air flow at low static pressures.This fans motor and impeller are both in the air stream which provides effective motor cooling and dissipation of heat generated by the electronics. Applications for these fans include: cooling cabinets, medical appliances, motor control cooling, power converter cabinets, heat exchangers and clean room modules.
Corrosion Resistant Wall Exhaust Fans are the right choice for areas that have caustic and corrosive fumes, gases and particulates in the atmosphere. You will find corrosive environments in many industries, such as; agricultural facilities; refineries, oil fields, dairies, pork and poultry barns, paper mills, paint booths, plating businesses with dip tanks, steel working, processing plants, laboratories and chemical plants. These corrosive environments that can negative residual affects on equipment performance. This degradation can result in the need for more frequent repairs and replacement of equipment.Â

Types of Mounts
A high-quality bathroom fan, bath fan kit, or duct inline fan is important because the areas that they work in necessitate their use at all times, and failure of the fan can lead to mold, mildew, and other air quality issues that can become costly over time.
These fans can be purchased in either a ceiling mount or wall mount version depending on your individual situation. The ceiling mount version works with your home or building's existing ductwork to exhaust the air to the outdoors. The wall-mount type of bath fan typically mounts from outside the building and removes the air from the restroom or locker room directly through the wall without needing any ductwork.
Sizing and CFM Rating
Bathroom fans are rated like other types of exhaust fans, by the amount of air movement or CFM they produce. Sizing of your bathroom fan is very important and should produce at least 1 CFM for every square foot of the room.
In larger bathrooms such as public restrooms, fitness centers, hospitals, schools, etc... where the lavatories or locker rooms are over 100 square feet, and have multiple toilets, showers, and sinks more CFM is required. Typically it’s suggested that an additional 50 CFM per toilet or shower is appropriate. Again, under-sizing your bath fan can cause issues with odor, mold, or mildew.
Features of Bathroom Fans
Features that may be offered in a bathroom ventilation fan are things such as:
- Lighting - for a subdued light ambiance if full lighting is not necessary
- A speed control - for varying the CFM volume of air movement the fan produces. This can be good when you are not needing to remove excess moisture present in the air.
- A timer - so that you can set the fan for when people are showering and causing a moist atmosphere
- A humidistat - which will automatically turn the bathroom vent fan on or off based on the humidity level.
Noise Level and Sones
Noise level of the fan is also a very important feature of any high-quality ventilator. The level of noise these types of fan produce are rated in what is known as Sones.
Sones rating is the measurement of sound as it relates to how it is sensed by the average listener. One sone is the equivalent of a refrigerator hum. Finding a bath fan that’s rated at or below 2 sones is recommended. Fans rated above this can cause a white noise or worse. Unless you are fond of a noisy fan, you should stay away from a unit that is rated at 5 sones or above.
Brands and Purchase Options

FAQs
To find the best bathroom exhaust fan that’s right for you, choose based on room size: small bathrooms (up to 50 sq. ft) need 50 CFM; medium (50-100 sq. ft) require 70-100 CFM; larger bathrooms (over 100 sq. ft) use 100+ CFM. Always round up for efficiency.
A bathroom fan specifically ventilates bathrooms, removing moisture and odors. An exhaust fan, which can be used in various spaces, expels indoor air to the outside. Both promote air circulation, but bathroom fans target bathroom-specific issues.
A good wattage for a bathroom exhaust fan typically ranges between 20 to 60 watts, depending on size and performance. Choose one that's energy-efficient and appropriate for your bathroom size.
Yes, bathroom exhaust fans should be vented outside to effectively remove moisture and prevent mold growth. Avoid venting into attics or crawl spaces.
Bathroom fan CFM (Cubic Feet per Minute) is calculated based on bathroom size. Typically, you need 1 CFM for every square foot of bathroom space. Adjust for larger bathrooms or added features like a shower.
