Pick-and-Place Suction Fan Noise Reduction – a packet quieter…

Pick and place fan noise reduction

This suction fan used in a newly designed, automated pick-and-place system for food packets on a production line generated high levels of noise.

Conventional fan silencing would not only have posed a hygiene problem (attenuators make use of porous acoustic absorbent materials), but would also have required acoustic enclosure. We re-designed the fan mounting system (interestingly, the fan itself was designed for model aircraft engines) and modified the geometry slightly.
