Fabric Filters for Woodwaste Dustraction manufacture a wide range of modular filter systems specially designed to handle woodwaste. They incorporate tubular filter bags which are essential for large particulate matter, reducing the risk of bridging and blocking. The filters are equipped with automatic shaker mechanisms and the waste can be discharged into waste sacks, bins, or via a hopper and rotary valve into an enclosed skip. Reverse Pulse Fabric Filters These are a compact form of fabric filtration and are designed for continuous operation with the minimum attention. They can filter fine particulate and achieve collection efficiencies in excess of 99.99%. Dustrax reverse pulse fabric filters are used in many industries which need to handle heavy dust burdens on continuous process.
