In many plants, leaky bag detection is difficult because of the extensive duct work from the dust collector to the main induced fan. Visually observing emissions requires a person to physically view the outlet of the fan or to measure or monitor the HEPA filter used prior to the fan. The most effective way to monitor and identify leaking bags is to first have a broken bag detector installed. The detector monitors normal dust levels while in operation and alarms when those levels exceed a pre-set level. Once you have been alarmed to a problem, we recommend you consider using “Detect-a-leak”. This is a process where you induce a specially formulated fluorescent powder upstream of the dust collector and utilize a high intensity lamp to illuminate the powder that has accumulated or leaked through faulty seems or holes.
