Industrial professionals, this Solberg paper filter element is built tough for heavy-duty applications. With dimensions of 2-5/16 inch height, 3 inch inner diameter, and 4-3/8 inch outer diameter, this filter delivers reliable 35 SCFM performance day in and day out. The heavy-duty industrial paper is surrounded by heavy gauge galvanized expanded metal - meaning this thing can handle some serious work without falling apart. It features optimal sealing surface design and offers 99% plus removal efficiency (2 micron for paper, 5 micron for polyester). The filter change out differential is 10-15 inch H2O above initial delta P, giving you plenty of warning before maintenance is needed. Way more cost-effective than constantly replacing cheaper filters that don't last. Perfect for compressed air systems, industrial machinery, and any application where you need consistent, reliable filtration. If you're tired of filters that clog too quickly or don't stand up to industrial conditions, this Solberg element is exactly what you need.
