CYCLONAIRE'S bin vent/dust collectors provide air filtration and dust control for dry bulk materials conveyed pneumatically to destination points, such as bins, hoppers, and silos. The bin vent is compact in design and easy to install. Presettable timers clean the filter media automatically with pulse jet air flow, dropping retained material back into the process. An array of sizes and features are available, including a hinged door for easy bag access and differential pressure gauges that indicate when service is needed. High temperature and top removable designs available.
