Use cases & applications
Heavy-Duty Continuous Operation
In equipment running long shifts, such as construction machinery from Atlas (Terex), the 25 µm inorganic microfibre media provides consistent filtration to reduce wear and extend oil life, minimising downtime for filter changes.
Hydraulic System Protection
For Hydac hydraulic systems operating under high pressure, this filter captures fine particulates down to 25 µm, preventing valve sticking and pump damage, ensuring smooth operation and longer component life.
Fleet Maintenance Consolidation
When managing a mixed fleet of equipment from different brands, this single filter cross-references multiple OEM numbers, simplifying inventory management and reducing the risk of stocking the wrong part.
Cold Climate Start-Up
In cold environments where oil viscosity is high, the filter's robust construction and media ensure reliable flow and filtration from the first start, protecting engines during critical warm-up phases.
Frequently asked questions
How can I confirm this filter fits my specific machine?
Check your equipment's manual or existing filter part number against the cross-reference brands listed (e.g., Mann-Filter, Hydac). If your filter matches one of those brands, this filter is a direct replacement. For Atlas (Terex) and Hydac equipment, it is compatible, but verify dimensions (height 198 mm, OD 45 mm, smallest ID 20.5 mm) for a proper fit.
What is the filtration rating and media type of this filter?
This filter uses inorganic microfibre media with a 25 µm filtration rating, designed to capture particles of that size and larger, providing effective protection for engines and hydraulic systems.
What are the exact dimensions and thread specifications?
The total height is 198 mm, outer diameter is 45 mm, and smallest inner diameter is 20.5 mm. Thread specifications are not provided; refer to your original filter for thread size or contact us for assistance.
Is this an OEM filter or an aftermarket replacement?
This is an aftermarket replacement, not an OEM part. It is built to the original dimensions and ratings and cross-references multiple brands, offering a cost-effective alternative without sacrificing quality.
How do I install this filter?
Installation is similar to standard spin-on or cartridge filters: clean the mounting surface, lubricate the gasket, hand-tighten until snug, then check for leaks after startup. Always follow your equipment's service manual for specific instructions.
