High-quality RABH Reverse Air Filters from BWF Envirotec
The design of our Reverse Air Filter Bags differs from conventional filter bags as they work in a different way. Filter bags for Reverse Air Filters must therefore also be mounted differently. A special holder is sewn into the closed upper end of the filter bag to attach the reverse filter. The filter bag is mounted to the baghouse using this bracket. The open lower end of the Reverse Air Filter is connected airtight to the head plate of the baghouse. In filtration mode, the dust-laden gas enters the reverse filter from below. On its way upwards, the gas flows outwards through the fine filter, depositing the dust on the inside of the filter bag. When filtration is running, a filter cake forms on the inside of the filter bag over time. To remove this dust from the surface of the reverse filter and maintain filter efficiency, a backwash is carried out periodically.
