How Do Axial Fans Ventilation Support Natural Ventilation?

Axial Fans Ventilation

Natural ventilation is the single most efficient and effective cooling system available. Unfortunately, it doesn’t work in all building types. Spot cooling or powered intake are effective ways to compliment a natural ventilation system. Of course, they also maximize energy efficiency and lower operating costs. Adding axial fans ventilation is a good way to add a little extra to a ventilation system.

Natural ventilation works by pushing out the hot air that accumulates inside the building. It helps to cool the building and facilitates the drawing in of fresh air from the outside. This is due to the differences in buoyancy and the air pressure inside and outside of the building. Natural ventilators are great at removing lots of heat naturally. Yet they don’t work in every situation.

Axial Fans VentilationIn locations deep within a larger facility or in enclosed locations, a fan may be required. Fans might also be necessary for smaller spaces with a low heat load or low ceilings. Installing a fan, with or without duct work and duct drops, is a good way to pull the hot air out of those spots. With the hot air removed, these spots can feel the benefits of the natural system. A powered fan is an effective way to suck up the hot air from key parts of a building.

Types of axial fans

There are many types of axial fans as well as many options that can be applied to them. Probably the biggest difference comes in motor alignment. The difference between the two is clear as the direct drive fan has the blade assembly attached directly to the motor where as belt drive fans utilize a belt system to turn the fan blade.

Most fans have an array of options including blade pitch adjustment, motor horsepower, and mounting angle tuning. They are available in a variety of different casings and can be fit to meet different ductwork configurations.

Axial fans have proven to be the ideal choice for exhausting large air volumes from schools, commercial buildings, power plants, warehouses, industrial plants, and equipment rooms. Despite their size, today’s fans are very energy efficient and are very effective at removing stale air and bringing in much needed fresh air.
