Double-flow radial fan
Radial fans for large volumetric flows
Radial fans are an indispensable part of most operational processes in ventilation systems. In cases where extremely large volumes need to be moved or transported, or where a critical impeller mass is exceeded, radial fans with bearings at both sides are an ideal choice. This type of equipment is available in single-flow and double-flow versions.
However, the robust design of Scheuch COMPONENTS radial fans makes it possible to achieve large volumetric flows even with unilateral bearings (i.e. single-flow systems).
Bearings can be provided on both sides if requested by the customer, and this configuration is implemented as standard above a critical impeller mass.

Double-flow radial fans
Double-flow radial fans achieve a high power density despite their compact size, and their special design enables them to produce a clean flow pattern.
The two suction openings and bearings at both sides result in a volumetric flow that is practically doubled in comparison to single-flow radial fans, with the same impeller diameter and the same flow velocity.
What are the standout features of double-flow radial fans?
With their flow-optimized suction pockets, double-flow radial fans make it possible to create efficient designs for transporting and diverting conveyed media – even when space is tight.
Altogether, there are various factors and criteria that make double-flow radial fans a favourable option. These include:
• compact design for cramped production sites
• excellent performance when transporting media
• clean flow pattern
• customization options (e.g. to suit transport and cooling)
Are there additional options available for double-flow radial fans?
A version with a continuous steel bracket or a concrete foundation is available for on-site installation.
Where are double-flow radial fans used?
Double-flow radial fans are the perfect choice in any application that needs to transport or move extremely high volumes of media, and their compact size means they take up very little space even in cases where conditions are cramped. They can also be used in applications related to specific industries, such as:
• the cement or glass industry
• the coal and steel industry
• the metals industry
• test stands and industrial workshops
Flow-optimized suction pockets
If bearings are mounted at both sides, the suction-side pipe connection is usually established via flow-optimized suction pockets. The special design creates a flow pattern that results in very little turbulence at the inlet, which in turn optimizes the filling ratio and the impeller efficiency. Casing angles and suction pocket angles can be combined flexibly in a way that makes it easier to install the system in the system.
What are the benefits of double-flow radial fans from Scheuch COMPONENTS?
The compact design of our double-flow radial fans makes it possible to achieve extremely large volumetric flows. Each double-flow radial fan features a shaft that is as short as possible owing to the flow-optimized suction pockets and the installation dimensions that are reduced as a result. This creates the right conditions for efficient operation and cuts down on costs.
Our range of additional and safety equipment for radial fans is just as extensive as it is for our fans with other designs.
What criteria should be used to select a double-flow radial fan?
There is a whole range of designs and sizes to choose from when selecting a double-flow radial fan, depending on the function and power you are looking for. Blades and impellers are also important functional factors to consider.
Additionally, it is vital to think about the level of efficiency you need, the aerodynamics and the temperature at the operating site. Using appropriate simulation processes is an excellent way of determining the efficiency that can potentially be achieved. Here at Scheuch COMPONENTS, we use CFD simulations to optimize our radial fans.
What does a CFD simulation do?
CFD stands for Computational Fluid Dynamics, a branch of numerical fluid mechanics. Carried out properly, a CFD simulation makes it possible to adjust, visualize and optimize flow processes involving components through which flows take place and objects around which flows need to travel. Our theoretical calculations are verified with models on our test stands and undergo continuous development. We then use these calculations and similar representations to ensure our radial fans perform extremely efficiently in practice.
Strength calculations in the context of FE simulations allow us to keep improving the design of our radial fans and expanding the volumetric flow range for impellers. Through our CFD simulations, we are happy to help you find the right solution for your specific operating processes.
