In order to reduce contamination which could be introduced by a conveyor in a class 100 environment, the rollers of the conveyor system are coated or clad with a rubber coating. This, however, causes the conductive objects being conveysd, such as a disk drive, to accumulate a static charge which, if not appropriately conducted to ground potential, could damage circuits of the disk drive or could damage testers to which the disk drives are being conveyed whereby the testers would not properly electrically test the disk drives. The grounding is provided by positioning light stainless steel brushes 10 between rollers 20. The brushes 10 are attached to electrically conductive conveyor frame members 25 which are suitably connected to ground potcntial.
