Preventive maintenance of fans and components in industrial ventilation systems ensures a long service life. A perfect scheduling of maintenance reduces necessary plant shutdown to a minimum. Operating conditions and system parameters must be checked continuously and target/actual comparisons recorded. Stationary balancing test stands and mobile balancing devices are also used.

• Condition and function control of fans
• Review of slide and roller bearings as well as oil change
• Vibration test
• Balancing of fan impellers and shafts
• Checking the drives
• Measurement of air flow, pressures and temperatures
• Determination of dust and particles in the medium
• Measurement of vibrations and sound emissions
• Determination of the material quality, wall thickness and quality of the weld seams
