A Food Truck exhaust fan is very crucial in operating your mobile restaurant and some municipalities legally require them. Note that all fans do the same basic thing: move air from inside your building to outside. However, your food truck exhaust fan must move hot, dirty, greasy air through your hood system and vent it outside.

How Does an Exhaust Fan Work?
These fans work by sucking hot or humid air out of a small, localised area, allowing fresh air to enter from elsewhere (perhaps a doorway or vent) in order to replace it. The warm air that’s drawn out using an exhaust fan is then pulled through a ducting system and expelled outside.

Factors to Consider Before Deciding on a Type of Exhaust Fan to Buy
Since these fans are only really effective in smaller spaces, one that is capable of moving approximately 2 cubic metres per second usually provides sufficient ventilation. For larger trucks, a larger ventilation system may be more appropriate.
Also note that the effectiveness of exhaust fans is really dependent on the size of your truck and the airflow rate necessary for that area. How much air an exhaust fan can shift over a given amount of time is most commonly measured in cubic feet per minute (CFM), but is also referred to in terms of cubic metres per minute (m3/min).
Remember that the amount of air a fan can shift depends on both its size and speed. A small fan most likely will shift the same amount of air as a large fan, but would normally have to be oscillating faster to do so – depending on how the fan’s constructed, this may also make it noisier.
According to experts, the easiest way to know what size and speed of fan you require is to figure out the volume of your food truck, then multiply it by the number of air changes you’ll need to keep it clear. If in doubt, ask a retailer or qualified installer.
Best Place to Install an Exhaust Fan in a Food Truck
Also note that for an exhaust fan to perform at maximum efficiency, it needs to have access to balanced airflow. This simply entails that the volume of air being exhausted by the fan must be matched by that flowing into the truck. The best source of this in – flowing air is fresh air either from a window, vent or grille in a door or exterior wall.
It is also necessary to position the exhaust fan opposite the source of in – flowing air to encourage a cross – breeze that is very important to clear vapour and odour. Note that if you have no air entering your truck through a window or vent in your door, the exhaust fan will be unable to extract any air.
Remember not to position an exhaust fan too close to a door / window as this will offer air circulation at the door / window but have little or no effect on the rest of the room.
Getting an exhaust fan for your truck might not be a top priority to you, but it actually has a big role in keeping you well and healthy. Note that the ‘stale air’ and sharp smells in the truck are not just unpleasant to inhale, but might also have negative effect on your health, especially since the space is quite small.
You can get health problems such as asthma, constant headaches and light – headedness, or it can even trigger an allergic reaction in some people.
