Large Diameter Industrial Grade Pre Filter Element – Model 85565851

The 85565851 is a large bore pre filter cartridge engineered for central compressed air systems serving entire industrial complexes. Its 101 mm diameter and 266 mm height accommodate a massive volume of micro fiberglass depth media, capturing solid contaminants down to 1 micron — including heavy rust, large pipe scale, weld slag, and bulk liquid carryover — at flow rates far beyond the 77 mm series capability. This element is purpose built for main plant headers, compressor rooms feeding multiple buildings, and heavy industrial applications where smaller filters would become bottlenecks.

Rated at 9.62 Nm³/min, the 85565851 supports whole factory air distribution networks, multiple high consumption laser cutting tables across several production halls, entire electronics mega campuses with dense SMT lines, or continuous heavy sandblasting facilities. The extra large 101 mm diameter reduces face velocity dramatically, allowing deep particle penetration and exceptional dirt holding capacity. Clean pressure drop is ≤0.01 bar, delivering 5-7% compressor energy savings over the 8000 hour service life. Weight is 0.65 kg — substantial yet manageable for this capacity class.

This element is the preferred choice for large scale facilities seeking to minimize filter count and maintenance frequency. Typical placements include central compressed air rooms for automotive stamping plants, heavy fabrication laser centers, electronics industrial parks, and sandblasting operations with multiple large nozzles.
