FOR INDUSTRIAL FANS OF EACH SIZE 

Good suctions units are absolutely necessary - as well as excellent balancing systems!
The life-time of your suction unit will be much longer and the maintenance costs will be reduced considerably!  

Above all: 

• in case of a noisy run 
• if noise pollution increases 
• if deposit of dirt and dust cause problems at the bearings (only a question of time!)
• if the disassembly of large fans (e.g. on a roof) requires a lot of time and energy
