Precoating new filters for better airflow, longer filter life
After explaining why it's a good idea to precoat new bag and cartridge filters that will handle extremely fine dust particles, this article provides step-by-step instructions on how to do it.
Why consume expensive downtime to precoat (or seed) your dust collector's new filters? One good reason: Dust and fine particles 0.5 microns or smaller can leak right through a new bag or cartridge filter's pores, working their way deep into the media to the point of blinding, or clogging, the filter and slowing or stopping airflow through your collector. so if your dust particles are smaller than 10 microns, taking the time to pretreat your new filters' media surface with a dry precoating material -- such as agricultural lime or diatomaceous earth -- is smart.
