Commercial Exhaust Fans: How to Choose the Right Type You Need

Commercial exhaust fans are widely used across different industries. It can be expensive to install or update commercial and industrial ventilation. Agencies and business owners can save money by finding high-quality exhaust fans. And companies and industries can remain in keeping with codes and regulations while making working conditions safe for employees if they find the right type and size of the fan. Choosing the right equipment can make a difference whether you use the commercial exhaust fan in a school, factory, gymnasium, storage facility, commercial kitchen, or outbuilding.

You can choose from different commercial exhaust fans for ventilation and exhaust for your need. For example, local exhaust ventilation fans capture fumes and pollutants before they are circulated and help prevent indoor air contamination. You can find these types of hooded systems in commercial kitchens, chemical industrial environments, wood-working factories, restrooms, and metal shops, among others.

Acceptable indoor air quality is generally defined by diluting odors, airborne pollution concentration, heat, and humidity. Commercial exhaust fans and equipment can help attain acceptable indoor quality regarding air changes per hour (ACH). You should size exhaust systems depending on room or area dimensions, environment type, and the acceptable range of temperature and humidity.

With sizing, you should design and fit your commercial exhaust fans keeping in mind pollution control. Inappropriate design and installation can trigger indoor air contamination, static pressure imbalances, odors, drafts, and ineffective environmental control. You should lay out exhaust ducts directly to outdoor vents in the utmost direct way. You should never place exhaust vents near supply air vents so that fresh outdoor air does not get contaminated with the polluted exhaust air.

Commercial Kitchen Exhaust Fans:

The heart of every kitchen ventilation system is the commercial kitchen exhaust fan. The commercial kitchen hood exhaust fans capture the smoke, grease, steam, heat, and other food associated vapors into the system by circulating airflow through the kitchen exhaust hood.


How to choose the right Commercial Kitchen Exhaust Fan


Choosing the right commercial kitchen exhaust fan is important because if you fail to get the proper system, you will be leaving your restaurant, diners, and employees at risk.

Your commercial kitchen exhaust fan, alongside your restaurant vent hood, ductwork, and hood filters, is among the most important things in your kitchen. You can keep the air free of contaminants and make a more comfortable environment with the right commercial kitchen exhaust fan for your restaurant. Reducing the fire risk of your commercial kitchen is also crucial.


The right commercial kitchen exhaust fan for you will be determined by the type of cooking you do and the type of fuel you use for cooking. Restaurant exhaust fans have two basic types. One is the upblast exhaust fan, and the other is the down blast exhaust fan.


1. Upblast Exhaust Fan


The upblast exhaust fan is meant for exhausting fat, grease, and oil effluent along with smoke, heat, odors, and moisture. It pulls hot air, smoke, contaminated air, grease, oil, and other particulate matter. It works through your hood filters and the restaurant vent hood and duct system. Most commercial kitchens will need one upblast exhaust fan with a hood system. Upblast exhaust fans are usually installed on the rooftop.


2. Down Blast Exhaust Fan


The down blast exhaust fan is intended mainly for exhausting air. A down blast fan should never be used to exhaust heat or moisture since it could instigate damage or corrosion to the motor.


The working of down blast exhaust fans is much like an upblast fan. The chief difference in their working is that it is in a downward blowing direction that a down blast fan exhausts the air. They are also usually placed on the rooftop of a facility.


Conclusion


If you are trying to find the right type of commercial exhaust fans you need for your company or industry and are unsure which one you should choose, the above will help you!
