One-piece Radial-fin Design
The one-piece radial-fin design of Dollinger filter elements has many advantages over the conventional multi-cartridge option. It provides a larger filtration area, extra dirt holding capacity, and lower pressure drop. In addition, it results in longer service life and greater ease of maintenance.

Fiberloc^© Filter Media:
High-Temperature Filtration
For high-temperature applications, woven glass was the industry standard for many years, but the glass fibers tended to migrate downstream, causing contamination and other problems.

That was until Dollinger research and development created Fiberloc© 197 filter media. Today, Fiberloc© filter media continues to outperform woven glass, time after time - with no evidence of migration.

Fiberloc© media is rated at 99.9% efficiency at 3 microns and 98% efficiency at 1.5 microns, at temperatures up to 1000° F. The Fiberloc© filter media structure has up to three times greater dirt-holding capacity than conventional media.
