EC centrifugal fans for ventilation applications - ebm-papst A&NZ

ebm-papst A&NZ’s Managing Director Dr Simon Bradwell presents the use of EC centrifugal fans in high-efficiency ventilation systems.
High-efficiency EC fans for ventilation systems are now becoming significant in Australia and New Zealand. They are being used in fan coils, fan-assisted VAVs, as well as domestic and commercial ventilation systems. This includes particularly EC backward-curved centrifugal fans.

Why?
The advantage you get with EC fans is simple control. An ebm-papst EC RadiCal fan can be controlled using simple 0-10V input. For the application it means that the commissioning engineer or contractor can commission the airflows across the system in a simple way, particularly in light commercial applications.
In domestic applications it means that the temperature inside the residence can be simply controlled with a temperature sensor into a PCB which then gives a 0-10V signal to control the fan off temperature. Other variables such as moisture and static pressure can also be used to control ventilation applications.
ebm-papst have developed two different product types which are designed specifically for this type of application. Firstly the RadiCal EC centrifugal fan, a composite-material moulded impeller which allows optimum airflow through the product.
The second product is the RadiPac EC centrifugal fan, which is designed for slightly higher static pressures than the RadiCal fan. The animation shown in the video illustrates the simple, high-efficiency airflow through an AHU system, an important consideration for ventilation applications. The ebm-papst impeller design, coupled with the EC motor allows the Original Equipment Manufacturer (OEM) to design the new product and the end user to get a good system which gives them exactly what they want.

Summary
• High efficiency ventilation systems are becoming more significant in Australia and New Zealand
• RadiCal and RadiPac EC centrifugal fans are typically used in these types of applications
• They are used because they give simple control and high efficiency airflow.

Can you pls guide me how to connect the small three wires in order to start this fan ...
And may I ask if this fan needs a capacitor??
And thanks a lot your guidance..

Can you help me? I have 2 R3G190-RC05-03 units that have become noisy. Andy advice or do you know how I can get hold of replacement bearings?
