Particle Counter Figure 1

There has been increasing interest in specifying the efficiency of ventilation filters at PM2.5 and PM10. PM is a statutory measure of outdoor air quality determined according to strictly specified procedures, or their approved equivalents. In this paper, an attempt is made to relate the measured differences to published theoretical comparison for single particles. The …

Power generation is one of the primary applications for hot-gas filtration

Hot gas filtration is a process utilized to remove particulate in high temperature gas streams. Depending on the process, the temperature ranges can very between 250 C to 1,000 C. The lower range can be serviced by synthetic fabric filters in the form of a bag and cage or pleated elements, whereas higher temperatures require …
