Filter collection systems have long been in the forefront for high-efficiency separation of fine particulate dusts from gas. Today, new technology and designs have improved filter collection systems even more. These improvements to primary systems (baghouses) and secondary systems, and new instrumentation can lower investment and operating costs, while also improving environmental compliance. In comparing the collectors offered by different vendors, one should consider the different designs, cloth area, critical velocities, and methods of cleaning the fabric. The sizing and selection of a filter should be made by actual test or experience at the design load, using the least costly fabric for the requirements. This paper discusses optimizing velocity, new collector designs, higher temperature filters, secondary filters, the goal of 99.99% efficiency, cleanable HEPA cartridges, instrumentation and valving, and a photohelic gage controller.
