Adjusting Dust Collector Fan Dampers to Save Time and Money
Initially when a dust collector is commissioned, the service technician will measure the total air volume and the duct conveying velocity to assess proper dust control at the hoods. He will then set and record the fan damper position. Over time, as dust accumulates on the filters and then gets pulsed off, differential pressure and airflows change. Fan dampers should be adjusted accordingly. Read more about why and when to make these adjustments...

Using MERV Ratings to Determine Effectiveness of Industrial Dust Collectors: How Appropriate?
Standards to appropriately and accurately measure the effectiveness of industrial dust collector systems have never existed. Since many dust collector and filter manufacturers make claims about their products’ performance, many end users find themselves lost in a world of boasts and promises. In an effort to implement a basis for comparison, many companies, industries, and jurisdictions have resorted to the application of MERV ratings, established by ASHRAE 52.2 for the general industrial ventilation cleaning industry. But is this an appropriate measurement of effectiveness for industrial dust collectors? Read the full article

An Optimized Approach to Dust Control in Grain Elevators and Terminals
Over 18 billion bushels of grain are produced and moved through grain handling systems in the US each year. The ability of the United States to feed its populace and livestock, support the biofuels movement, and export excess grain to emerging markets is a point of national pride and strength. The infrastructure for moving grain from one point to another includes small country elevators, larger elevators, large grain terminals, trucks, trains, barges, and ocean going shipping vessels. And every time grain is moved from one of these points to another, dust is generated. Dust which must be controlled, captured, and contained. Read the full article
