Gear Oil Filter Elements

Anderson gear oil filter elements are engineered specifically for the high-viscosity demands of gear oil service. The HVF-Series uses ultrafine micro-fibrous media with internal structural support to maintain pore integrity under the elevated differential pressures common in gear oil filtration, protecting gearboxes and drive systems.

Available Element Series

HVF-Series — High Viscosity Liquid Particle Filters

High Viscosity

Designed for use with high-viscosity oils including gear oils. Suitable in all mineral-based and synthetic lubrication fluids. Ultrafine micro-fibrous filter media with internal structural support ensures pore integrity under the elevated differential pressures associated with high-viscosity gear oil service. Provides absolute rated particle removal to protect gearboxes and drive systems.
