Filters & Filter Housings

Filters — New & Used

Industrial filters protect equipment and systems by removing contaminants from air, liquids, oils, and gases. From air intake and hydraulic filters to oil separators and particulate filters, these components extend service life, maintain flow efficiency, and prevent costly downtime. Available in cartridge, spin-on, and in-line configurations, our filters serve industries from manufacturing and automation to HVAC and fluid power systems.
