How to Diagnose Loss-of-Vacuum Problems in Central Conveying Systems
Conair service technicians and sales people often hear processors complain that their conveying system is not performing as well as it used to.
Some receivers take longer to fill, or fill incompletely, even though system settings have not been changed. Alarms ar triggered when demand at the machine is not being met despite multiple attempts.
