When it comes to dust collection in the chemical process industries (CPI), there exists a wide variety of needs. For example, folks in dyes and pigments have a different set of dust collection challenges than those in the pharmaceutical industry, who have differing requirements from processors working with paints and varnishes. However, any and all chemical processors can boost process efficiency by...
