Air-Intake Filters
Stop dust and other contaminants from entering your process and equipment. Use these filters on blowers, compressors, engines, and in hydraulic systems.
Filters with silencer reduce intake noise by up to 15 dBA while maximizing air flow.
Consider the filter material when choosing replacement elements. Polyester and fiberglass elements are more durable than paper. HEPA elements are often used for high-purity applications, since they have the highest efficiency, but they reduce the maximum flow rate of your filter.
Wrap pre-filters around filter elements to protect them and extend their life.
