Like many, most individuals could not speak about the differences between ventilation fans and exhaust fans off the top of their head. In fact, many would think they are one in the same. However, that couldn’t be farther from the truth. Each fan serves specific purposes in both commercial and residential spaces that are crucial for supplying high-quality air throughout an area. This blog post will serve the purpose of describing the difference between these two types of intake air fans.

Ventilation Fans

As the name implies, ventilation fans are used to ventilate a residential or commercial space. This  works to bring fresh air from the outside and into the enclosed space. It helps circulate air through the building or home, which prevents individuals from breathing stuffy, less oxygenated air. Without ventilation, you and other individuals will be left breathing air that is not fresh.

Exhaust Fans

When pollutants and contaminants enter the air, exhaust fans remove them in order to provide clean air. Some common contaminants and pollutants include smoke, moisture, dust, and odors. Smoke from cooking and moisture from a hot shower can efficiently be removed from the air by this type of intake fan. If these contaminants are not removed from the air, you will subject your lungs to possibly breathing in harmful particles.

Differences Between These Fans

Both ventilation fans and exhaust fans work to create the freshest, cleanest air possible in the space they are installed. The main difference between the two types of fans is their application. While a ventilation fan works to bring clean air into an enclosed space from an outside source, an exhaust fan removes pollutants from the indoor air in a home or commercial space.

Industrial Fans, or industrial air purifier is perfectly positioned to supply you with the ventilations fans or exhaust fans you need to keep the air in your commercial or residential space fresh and free of contaminants. Each fan has its own unique properties and application, so it is important to place them in the correct space. In addition, selecting a fan with the proper CFM (Cubic Feet per Minute) is crucial to ensuring the fan operates as intended. A CFM that is too low will not be able to provide you with pristine air because it cannot move the air through the space efficiently.

How does Backward Curved Centrifugal Fan work?

The name, ‘Centrifugal Fan’ is derived from the direction of flow and how the air exits the fan impeller radially from the outer circumference of the fan. A Backward curved centrifugal fan is characterised by its cylindrical shape, several large curved blades and a conical inlet nozzle. The optimum operating area for a backward curved centrifugal fan is an area in the middle of its performance characteristic. A backward curved centrifugal fan works best when medium pressures and medium volume flows are required. 

Axial fans can be subdivided into two types, namely, vane axial and tube axial. Because of the type of construction employed, these fans lend themselves easily to multistaging if higher pressures are required. 

An AC duct booster fan is basically a fan that can be attached to the ductwork in an HVAC system. Designed to increase the airflow to the more distant parts of a home, a duct fan will typically be installed in long sections of ductwork and then hooked up to an electricity supply. Do inline duct booster fans work? Yes! Inline duct fans are built to be installed inside the ductwork itself. Because they can shift large volumes of conditioned air, inline fans are often used in larger properties with extensive networks of air ducts.

Inline booster fans look somewhat like a regular section of ductwork. They are designed to replace a section of regular ductwork, so it is essential to choose one with the same dimensions as your existing ducts.

An inline booster fan will cost somewhere in the region of $30 to $200 (not including installation costs), but once installed, they are cheap to run and do not use much in the way of electricity.

Portable air purifiers

You’ll find several types. Basic mechanical models use a fan to force air through a filter to remove particles. Those with higher-grade HEPA filters are certified to capture the smallest particles, including dust, smoke, pollen and pet dander.

Electronic home air purifiers are designed to create an electric charge so particles stick to metal plates in the machine, which you then carefully wipe off. Other models include a UV light and claim to kill mold and bacteria, but Consumer Reports has not tested those models, and there’s currently no evidence that they do what they claim, Santanachote says.

Some purifiers include an activated carbon filter to absorb odors and/or remove gases. While thicker, heavy-duty carbon filters are effective, they are ­pricey. Thin mesh ones are a waste of money, Santanachote says.

Expect to spend at least $200 on a portable unit. Top-rated models that purify large spaces may run up to $700. In addition, replacement filters cost $20 to $200 (a few models come with washable filters), and because experts recommend that you run purifiers 24/7, you’ll have to factor in electricity.

Don’t be dazzled by sleek looks or equate higher cost with better performance. Look for models certified by the Association of Home Appliance Manufacturers (AHAM). Then check the Clean Air Delivery Rate (CADR), which describes how well the machine reduces tobacco smoke, pollen and dust. The higher the number, the better. Less than 60 is poor, and more than 240 is excellent, Santanachote says.
