In dust collection applications, the MERV value has little bearing
on the long-term efficiency of the system. Most dust collector filters,
whether the filters are cleaned by shaking or pulsing with compressed
air, reach a steady state operating condition within the first couple
hundred operating hours. A layer of dust builds on the surface of the
filter, creating a dust cake that will typically remain on the filter
through its entire useful service. This dust layer makes the filter
more efficient than the stated MERV value, in effect, negating the
purpose of the rating in many instances.
What is important in most dust collection applications is that you
are using the correct filter media, the correct amount of media, and
the correct configuration to allow for proper cleaning of the filter.
When a dust collector system fails, it's more commonly one of these
factors that lead to its failure, rather than the MERV rating of the
filter. Trion’s engineers and authorized representatives have the
experience and knowledge to determine what type of filter is best
for your application. Contact them today to determine how Trion
can solve your dust collection application needs.
