Commercial exhaust fans, as the name indicates are used for commercial purposes as in restaurant kitchens, public toilets, stores etc. Compared to our home-use exhaust fans, commercial exhaust fans come in higher capacity, bigger sizes and build more durably to withstand constant use.

Commercial exhaust fans are used in restaurant kitchens, green houses, small warehouses, office buildings etc, where general exhaust fans may fail to make any impact. The capacity of commercial exhaust fans is higher than general exhaust fans. They are also built with commercial uses in mind. For example, safety and security standards are very strict and defined in commercial establishment. So, commercial exhaust fans are built with these standards in mind. Therefore, grates, boxes and strong frames cover these exhaust fans.

Commercial exhaust fans can be of any type: bathroom exhaust fans for public or office toilets, kitchen exhaust fan for restaurants and burger joints and even ceiling or wall mounted exhaust fans for ;arge stores and warehouses.

Moreover, commercial exhaust fans also have to be installed as per regulation. So while you are shopping for an commercial exhaust fan, you might first consider talking to the electrician who will install the fan for you to find out what are the protocols involved in installing commercial exhaust fans in your kind of establishment. It is likely that a building inspector will drop in to check on the location etc of the commercial exhaust fan at some point.

While buying commercial exhaust fans, one needs to calculate the cubic feet of air per meter that the fan needs to exhaust to building standards as well. Not all commercial establishments can install any kind of commercial exhaust fans either. Rules and regulations will apply almost always when it comes to buying and installing exhaust fans in commercial establishment. Bathroom exhaust fans for commercial use have standards for noise as well and come with die casted body and noise reducing padding as well. Buy UL and ANSI certified commercial exhaust fans to be safe.

For places like small burger or kebab joints, a good exhaust system is very necessary, as it is openly visible to the customer. If their exhaust fan is not up to the mark, it will leave grease marks on the kitchen unit and these joints can have their license cancelled. Commercial kitchen exhaust fans with high-powered motor are the best choice for these commercial establishments. Commercial exhaust fans for kitchen also come with matching hoods to match with the rest of the unit in the shop. 

On the other hand, houses with huge halls and attics use commercial exhaust fans because the power required to exhaust such places is somewhat beyond that of regular exhaust fans. However, whether it is at home or at commercial establishment, commercial exhaust fans also need good ventilation systems to complement the boost in power. Good, well-insulated ventilation ducts with straight pipe ways make it easy for the fan to push out air more efficiently. Again, building rules and standards will effect this as well in most commercial establishment.  

While it is possible to use regular exhaust fans even in commercial establishment, if the space that needs exhausting is more than a commercial exhaust fan will be better suited. Also, remember an exhaust fan in a commercial establishment is used almost all the time and will suffer a hundred times more wear and tear than a regular exhaust fan. So, keep that in mind when you are making the choice. In addition, commercial exhaust fans cost more than regular exhaust fans. However, on the bright side, you are likely to get some bulk discount if you buy multiple units.
