APPLICATIONS
RADIAL FANS
Scheuch has built more than 70,000 industrial-grade radial fans to transport clean or exhaust air, chips, and fibrous material as well as explosive gas mixtures. Over the years, we have created and perfected a comprehensive program of roughly 1,700 fan types. These fan types range in pressure from 2″ WC (500 Pa) to 120″ WC (30,000 Pa), and their volume flows range from 300 to 600,000 acfm (500 to 1,000,000 m/h).3
Since these fans are used in particulate filtration and gas cleaning systems, Scheuch is well versed in a broad range of specific fan requirements for many different applications.
Selecting the right fan design has a significant impact on investment and operating costs. Schuech fans are divided into a range of model types that consider the relationship between the overall pressure increase and the volumetric flow.

- Belt drive
- Coupling drive
- Custom to application
An optimized fan inflow has a significant influence on efficiency and energy consumption. We perform calculations for a variety of baffle plate configurations using computational fluid dynamics (CFD) simulations to optimize the inflow for installation situations with limited space.

RESEARCH & DEVELOPMENT
Research and development has always been the heart of Scheuch. Scheuch designs its radial fans using cutting-edge measurement technology to meet the highest application requirements.
Scheuch radial fans achieve energy efficiency by boosting performance through flow optimization. An optimized fan inflow has a significant influence on efficiency and energy consumption. When it comes to planning, Scheuch consistently recognizes the importance of an efficient inflow and outflow. Computational Fluid Dynamics (CFD) simulations help us find the best inflow by running calculations for different baffle plate arrangements, which comes in handy when there isn’t a lot of room for installation.
Scheuch Test Bench
- Before shipping, the 2,500 fans produced annually in Aurolzmünster, Austria, undergo a half-hour test on the test bench. The bearing temperatures and vibrations of each fan are measured to optimize performance.
- Scheuch uses a test bench for new developments such as bionic wheels, wear protection, and high temperatures to test different materials to maximize fan life.
- The test bench can run fans up to 1000 HP (750 kW).
Proven Fan Engineering Expertise
- CFD simulations for optimizing flow technology
- Scheuch uses its own fan test bench (DIN EN ISO 5801) for performance measurements.
- FEM calculations
- We provide sound analysis, expert assessments, and proposed solutions.
- Upgrades to increase performance and safety











RADIAL FAN TYPES
DIRECT DRIVE
Cleaning fans, especially the impellers, often results in regular production downtime. When this occurs, each minute counts towards the system’s resumption. To minimize downtime, Scheuch developed the SwingOut and the PullOut direct-drive fan models. The impeller can be swung out to or pulled out from the housing without having to disconnect the duct from the fan. This allows for quick and easy cleaning of the fan, thereby saving both time and money.
Specifications:
- The fan wheel is mounted to the motor shaft.
- The weight of the wheel is limited to the dimensions of the motor.
- 2-115” WG Static Pressure increase (710Pa up to 28.800Pa)
- Flows between 420 and 100,000 ACFM (710 m³/h up to 168,000 m³/h)
- Temperatures up to 2,200° F (1204° C)



SwingOut Fans
The entire sub-assembly can swing out to the rear thanks to the installation of both the motor and impeller on a single door. This makes the impeller easy to clean and to remove when necessary. Even larger fans with an impeller weight of several hundred pounds are available. The Swing-Out model is available with an impeller diameter up to 49″ (1,250 mm).

PullOut Fans
The PullOut fan is available for both direct drive and coupling drive. You can easily clean the fan by removing the impeller from the housing, along with the motor bracket and the motor itself.

RADIAL FAN TYPES
COUPLING DRIVE
The coupling drive fan wheel is mounted onto an extra shaft, and the motor is connected by a coupling. Scheuch offers large wheels for higher air volume requirements.
Specifications:
- 2-115” WG Static Pressure increase (1.250Pa up to 28.800Pa)
- Flows between 420 and 445,000 ACFM (710 m³/h up to 756,000 m³/h)
- Temperatures up to 2,200° F (1.200°C)


RADIAL FAN TYPES
BELT DRIVE
Belt-driven fans are used in rough environments. Prior to the widespread use of frequency converters for fan speed regulation, belt drive discs could also alter fan speed.
Specifications:
- 2-72” WG Static Pressure increase (1.250Pa up to 18.000Pa)
- Flows between 420 and 395,000 ACFM (710 m³/h up to 672,000 m³/h)
- Temperatures up to 2,200° F (1,200° C)
