Considering a Big Ass Fan? Can it help you stay cool?
Big Ass Fans fit a niche that many commercial fans cannot. They build incredibly big fans—no, seriously. They’re big. These HSLV (High-Speed, Low-Velocity) fans allow for great quantities of air to be moved with minimal energy cost.
The aptly-named Big Ass Fans can range from 2.4 meters to 4.3 meters in diameter (for their Essence range), providing a wide circumference of airflow. This is most useful for maximizing or supplementing air distribution from HVAC (Heating/Ventilation/Air Conditioning) systems, or to create air movement in large commercial spaces that have no alternate means to draw air from the outside.
However, Big Ass fans don’t draw in fresh, cooler ambient air from the outside. Depending on what outcome you are looking for when installing a ventilation system, simply moving the same air around over and over inside a commercial space may not be the cooling effect you are after. The only cooling effect obtained by moving air around this way is a perceived effect for people who are working directly underneath the fan. The air passing around them will feel more comfortable. However, moving air around does not lower the temperature in the space.
So, what does a Big Ass Fan do?
A Big Ass Fan in principle operates like a far more powerful and efficient roof fan. It circulates air in each space, ensuring that the internal temperature of a space is equal. In colder winter months, this ensures rising heat gathering in the roof space is brought back down through the ceiling. In summer, it ensures that any cooler air is distributed throughout a space.
The Big Ass Fan does not actively lower the temperature in a room, because it isn’t actively pushing air out through openings like windows or roller doors. It does, however, circulate great quantities of airflow which helps meet workers or homeowners more comfortable.
Big Ass Fan Pros:
1) Wide Range
Big Ass Fans offer a large range of fans for both domestic and commercial properties. These range from their ‘Haiku’ range of domestic fans to their ‘Essence’ or ‘Powerfoil’ industrial fans.
2) Stylish Look
Big Ass Fans have a slim, minimalist look. You’re also able to customize the colour of your fan so it can match the commercial property it is installed in.
3) Great Airflow
Big Ass Fans move great quantities of air quietly, and effectively.
4) Quiet Operation
Big Ass Fans are well-known for their quiet operation, in part thanks to their direct-drive motors.
Big Ass Fan Cons:
1) Does Not Lower Temperature
A Big Ass Fan can create a refreshing breeze, but it won’t actively lower interior temperatures. It can help move air-conditioned air through a space, and it can help ‘push’ air through open windows or doors, but it won’t extract heat directly.
2) Steep Price per Unit
Some Big Ass Fan models can easily exceed $1,000.00 (AUD), while commercial Big Ass Fans can be as much as $3729.00 (USD). Though their performance is strong, the initial price can be intimidating.
A Solar Whiz roof ventilator is designed to be magnitudes more powerful than a roof fan. It serves as an elegant alternative to a roof whirlybird. It doesn’t operate like a Big Ass Fan. In fact, it’s a bit like comparing apples to oranges.
A Solar Whiz extracts hot air and replaces it with fresh, cooler ambient air from outside. This allows interior spaces such as roof cavities, factories, warehouses, indoors sport facilities (etc.) to maintain close to the ambient temperature outside without relying on steep installation and running costs for air-conditioning.
A Solar Whiz may or may not be what you’re looking to use it alongside air-conditioning (except evaporative coolers), as it can actively extract that cool air out (depending on installation). It can create a soft breeze as it draws air through air intakes, helping workers feel cooler & in turn increasing productivity.
Solar Whiz Pros:
1) Market-Leading Airflow
Solar Whiz has been providing Australian & international markets with market-leading airflow for solar ventilators since 2009. We’ve serviced thousands of Australian homes with residential ventilators. Our growing commercial range has been sought out to cool a large variety of business schools and halls in the sizzling Aussie summers. Our SW-RAF10000 or SW-RAF7000 have time and time again made people in work and leisure environments comfortable & cooler.
2) Cooling Capacity
Solar Whiz units flush hot air out of localized spaces, using cooler, fresher air from outside. You’ll feel heat quickly in giant warehouses or factories comprised of metal walls & roofing. Using a solar heat extractor like Solar Whiz exhausts hot air as before it begins to build and helps prevent excessive heat loads from building.
3) Flexible Installation & Accessories
If you want your Solar Whiz to run after daylight hours, we can set you up with a night operation/constant current kit. All you need to do is flick a power switch. Would you rather your Solar Whiz only run when it’s a certain temperature? We’ve got you covered. Our passionate team create great solutions for businesses with unique ventilation problems.
4) Cost Effective & Efficient Operation
Without using night operations/constant current modules to help power your units, you don’t pay a single cent for a Solar Whiz’s operation. They’ll run when the sun is out—which is when you experience the hottest and most uncomfortable work and leisure conditions. If you pair it with night operations, this requires minimal amounts of electricity to run at full capacity. You’ll notice the difference in both comfort and cooling costs with a Solar Whiz.
Solar Whiz Cons:
1) Doesn’t Benefit HVAC Systems
Unless using roof-space extraction methods, direct extraction from interior spaces can hinder cooling provided from HVAC or air-conditioning systems. The best use for Solar Whiz is to remove heat from large, hot spaces. This would be your home’s roof space or your warehouse/factory interior. This prevents heat-build from radiating through your ceiling.
Do I buy a Big Ass Fan? Or do I buy a Solar Whiz?
This really depends on what you want out of your ventilation system. If you want better overall airflow inside your property, or want even temperature through a home or business, Big Ass Fans might be for you. If you want to extract heat out as soon as it begins to build up, Solar Whiz might be for you.
Also, consider installation cost as this can be very high for Big Ass Fans systems due to the size and vibration of these very large units.
