Fan Test Benches
Measurement & characteristic curve determination of fans and blowers
Our fan / blower test benches are used to measure and record the characteristic curves of fans and ventilators according to DIN EN ISO 5801 and AMCA 210. The individual test benches can be designed for a wide variety of volume flow ranges from 1.5 to 100,000 m³/h, either as suction or pressure side chamber test benches. The chamber pressure can be designed individually. This makes it possible to simulate different load conditions on the test item. The use of specific measuring elements enables a measuring accuracy of up to 0.5% MW.
The performance measurement is carried out in accordance to DIN EN ISO 5801 and serves as verification for customers in production and maintenance. Characteristic curve determination is a key factor in the development and optimization of fans. The purpose is to provide energy-efficient fans and blowers with high efficiency and low energy consumption over the widest possible operating range. The optimization of fan series requires very high measurement accuracy and reproducible measurement results. The use of specific measuring elements enables a measurement accuracy of up to 0.5% MV on the EPE fan test benches.

Optimum measuring section design
Depending on the required measuring range, we select the optimum measuring section, e.g. LFE, venturi, ultrasonic meter, etc., for your system. With Laminar Flow Elements (LFEs), for example, wide measuring ranges of up to 1:100 with high measurement accuracy can be achieved using only one measuring element. If the measurement range is even wider, different
measurement paths can be combined.
Compact characteristic curve test benches
The compact characteristic curve test benches have a universal clamping plate for testing different test items (e.g. radial and axial fans). The hose connection allows the auxiliary blower to be operated in a separate room for noise reduction. The automatic characteristic curve determination is carried out via the individual and user-friendly software with LabVIEW.
Applications
- Measurement of fans and blowers
- Identification of characteristics on HVACs for vehicles
