Commercial Exhaust Fan | Commercial Exhaust Hoods

Restaurant exhausts fans – things to be considered before buying:

Restaurant exhaust fans make up an important part of any restaurant. They are very efficient in removed bad odors and improving the overall indoor air quality. Restaurant exhaust fans aid in removing the moisture as that can be reason to increase the level of humidity inside. The high level of humidity can result in mold, mildew, and growth of bacteria that can ultimately become a threat to the health of the employees and can violate the major health code.

There are two types of exhaust fan systems available in the market. The first one is the impeller fans that can remove unwanted air with blades that are similar in appearance to the airplane propellers. The other one are the blower fans that are quite similar to the hamster wheels. They are more efficient than the impeller fans and are often called squirrel cage fans. Most of the restaurant exhaust fans have an exhaust with a duct and a hood. Many restaurants that have a central exhaust system too can remove air from the entire building.

If you are going to buy a restaurant exhaust fan, you should weigh a few things before settling for any of them. Ask the vendor if the exhaust fan is too noisy and is powerful enough to remove all the bad odors right way. You would not appreciate the high electricity bills so settle for the one that is energy efficient. Buy the quietest and the most energy efficient exhaust fan which is lying in the same size range. All the restaurant exhaust fans have ratings printed over them that can help you compare the noise and the energy efficiency with others. You should look for a resultant exhaust fan that has replaceable parts and permanent lubrication. Do not compromise on the quality even if you have to pay a little more.

Choose the exhaust ducting with low resistance. At the same time, seal all the joints to insulate the fan from the unheated spaces. Make sure that the fan does not back draft and install the proper controls. Check for HVI ratings too. Good quality restaurant exhaust fans have them printed but if there is nothing specified, there is a good change that the fan will surely be noisy. Another issue that needs to be sort out while buying the exhaust fan is the cleaning problem. All the fans create static electricity that will attract the dirt to the fan.

This dirt is mostly the reason for the growth of mold and decreases the efficiency of the fan. You should be able to clean the restaurant exhaust fans every now and then. Many times when the fan is off and not functioning, the wind load can cause the outside air to enter the restaurant or the vice versa. Hence, check the flaps from time to time to ensure cleanness and durability. Weigh all the pros and cons before making up your mind. Check all your options over the internet and you will surely find what you are looking for.
