Critical Considerations for Clean Room Conveyors
Noise Levels. Noise can be a contaminant in the clean room. Although maximum permissible exposure limit for noise set by OSHA is 90 dBA, a range of 50 to 60 dBA is actually considered comfortable. There are no conveyors that can be run in complete silence. With all the working and moving parts that most conveyor processes involve, noise is ...
