The System: Central Vacuum for flour, sugar and dust related to an industrial bakery.
The Challenges: The system required explosion protec�on for handling combus�ble dust, however, the system is indoors and not near an exterior wall so standard explosion ven�ng was not an op�on. The collected dust needed collected in their standard waste roll off hopper.
The site did not want confined space entry when doing filter changes.
Dust Reclaim: The discharge is a rotary airlock with NFPA tolerances to quality as an explosion isola�on device
The system uses two level sensors. One is below the airlock to indicate the hopper is full. A second level sensor in the upper hopper to indicate cri�cal overfill or if there is an airlock jam
