Centrifugal Fans: ebm-papst (AC Motors)
Let customers speak for us
Australian Made Centrifugal Fans with German Made ebm-papst AC Motors
Centrifugal fans are also called “blowers” because of the high-pressure flow they are able to create.
The blades in centrifugal fans are mounted around a circular hub (motor). The rotating motion within this hub pulls air inside, then the pressure is increased and the air is pushed at a 90-degree bend through the fan. The higher pressure generated makes centrifugal fans a preferred option for when air must be transported through a long system of ducts or tubes. This higher pressure, however, comes at the cost of a higher market price.
Another advantage of centrifugal fans is that their blades are enclosed, making them safer to work with and more resilient to damage from solid particles sucked in with airflow. This makes centrifugal fans preferred for working in harsh conditions, such as subfloor spaces. Centrifugal fans are largely used to transport air in mines, where there is dust and debris from rocks and minerals in the air.
Components
German Made Centrifugal Fan with an AC Motor
This is the AC motor. It is a long life motor rated for 30,000 hours of operation. It is available in 150mm, 200mm, 250mm and 300mm sizes.
3 Speed Switch (150mm Low Profile Version Only)
The 4 position switch allows variable speed control between 0%, 50%, 75% and 100%. It can be removed from the fan and extended for remote installation elsewhere.
3 Pin Plug and Lead
Plug and play operation in a standard Australian power point or socket outlet, without the need for an electrician.
Inlet Duct Spigot
The inlet duct spigot is located before the fan motor. Air is sucked in from this point. Duct can be easily attached and securely taped, allowing air to be drawn in from elsewhere.
Outlet Duct Spigot
The outlet duct spigot is located after the fan motor. Air is blown out at this point. Duct can be easily attached and securely taped, allowing air to be exhausted elsewhere.
Versions
To make your installation simple, all of our centrifugal fans with AC motors have a pre-wired Australian plug and lead.
These options are exclusive to Fresh Ventilation.
Low Profile / Single Speed
Low Profile fans are only available in 150mm size.
Our Low Profile fan housing features an updated design with improved air deflection fins inside. The Low Profile version now has marginally more air flow with marginally less noise, as the improved fins create less air turbulence (compared to the Normal Profile version).
The smaller footprint means that Low Profile fans are recommended for shallow installations where access height is limited.
Low Profile fans are oval with a width of 340mm and a height of 217mm.
Low Profile / Single Speed fans with AC motors are single speed motors that run at 100% all the time.
Low Profile / Three Speed
Low Profile fans are only available in 150mm size.
Our Low Profile fan housing features an updated design with improved air deflection fins inside. The Low Profile version now has marginally more air flow with marginally less noise, as the improved fins create less air turbulence (compared to the Normal Profile version).
The smaller footprint means that Low Profile fans are recommended for shallow installations where access height is limited.
Low Profile fans are oval with a width of 340mm and a height of 217mm.
Low Profile / Three Speed fans with AC motors are three speed motors that run at 50%, 75% or 100% depending on the position of their rotatable switch.
Normal Profile / Single Speed
Normal Profile fans are available in 150mm, 200mm, 250mm and 300mm sizes.
Normal Profile is our standard fan configuration.
Normal Profile fans are round.
Normal Profile fans with AC motors are single speed motors that run at 100% all the time.

FAQ
Why are decibel ratings misleading?
Decibel ratings are misleading, and many manufacturers are simply dishonest. Please see our Instagram post HERE and our Instagram video HERE for a good explanation of the issue.
We've been installing fans for over 10 years. In that time we've tried everything available on the market, including all of our competitors' fans. We're confident that our fans, in an installed environment, are quieter than any comparable models on the market. Our decibel ratings have been independently tested by VIPAC Engineers & Scientists Ltd.
Frequency (pitch of the sound) is more important than overall noise (decibels). Most fans have a prominent motor ‘whine’ whereas our centrifugal fans have mostly airflow noise. Once installed, much of the airflow noise is eliminated by duct on either side of the fan, whereas motor whine still penetrates through building materials.
What is the difference between low profile fans and normal profile fans?
Low Profile fans are available in 150mm duct size only for shallow installations where access is limited. Low Profile fans are oval with a width of 340mm and a height of 217mm. Our Low Profile fan housing features an updated design with improved air deflection fins inside. The Low Profile version now has marginally more air flow with marginally less noise, as the improved fins create less air turbulence (compared to the Normal Profile version).
Normal Profile fans are available in 150mm, 200mm, 250mm and 300mm sizes. Normal Profile is our standard fan configuration. Normal Profile fans are round with a diameter of 342mm.
Can the fan speed be adjusted?
Normal profile AC motors are single speed motors. They run at 100% all the time.
Low profile AC motors are available as single speed motors (they run at 100% all the time) or three speed motors (they run at 50%, 75% or 100% depending on the position of their rotatable switch).
What is the airflow capacity of the fan motors?
150mm AC motors have a capacity of approximately 540 m³/h.
200mm AC motors have a capacity of approximately 885 m³/h.
How much power do the fans use?
150mm AC motors draw 48 W when running.
200mm AC motors draw 80 W when running.
Who manufactures the fan motors?
