Testing Laboratory

The suction-side duct and chamber test rigs, compliant to international industry standards, enable us to make all kinds of necessary measurements and tests in accordance with ISO 5801 on axial and radial fans. The performance tests of jet fans are conducted according to DIN EN ISO 13350. Fan sizes from 280 to 3.150 mm can be analysed aerodynamically, acoustically and for vibration characteristics.

The 2nd Testing Laboratory

In 2019, we put another testing laboratory into operation in which a further measuring chamber for "medium-sized fans" was built. Thus, "gapless" fans from D 250mm to D 3150mm can now be measured according to the current standards.
