Troubleshooting your reverse-air dust collector: A step-by-step guide
The low-pressure reverse-air dust collector has a mechanically simple design that provides efficient, reliable performance over the long term in a range of bulk solids applications. Like any dust collection equipment, this unit can develop operating problems over time. This article provides a quick reference to help you diagnose and fix five common operating problems with your reverse-air dust collector.
The reverse-air dust collector (also called a reverse-air filter) is a common fixture outside bulk solids plants that process grain, agricultural products, coal and other minerals, wood products, and other materials. This versatile large-volume unit can handle light-dust-loading applications, such as filtering dust in a dust collection system, and high-dust-loading applications, such as serving as a filter-receiver to separate material from air in a pneumatic conveying system. The reverse-air collector's filter elements are continuously, gently cleaned using low-pressure air that flows through a slowly rotating cleaning arm. This filter-cleaning method doesn't use plant compressed air, doesn't require a timer board or other controls, and minimizes wear on seals and other parts.
