Answers to 10 common questions about safety-monitoring filters
Safety-monitoring filters are critical in bulk solids plants that recirculate the air discharged from dust collectors back into the plant. Here’s information on how to apply these filters and what benefits they can provide.
Recycling the heated or cooled air discharged from a dust collector back to the plant can be a smart move in many applications because it saves the energy required to heat or cool fresh replacement air. A safety-monitoring filter (also called a safety filter, secondary filter, or afterfilter) is installed downstream of the dust collector's clean-air discharge in these applications to allow the air to be recirculated through the plant.
