Use cases & applications
High-Pressure Hydraulic Systems
In hydraulic power units operating at up to 12 bar, this filter ensures clean oil circulation, protecting pumps and valves from abrasive particles. Its wire mesh media is ideal for systems where frequent filter changes are undesirable.
Continuous-Duty Lubrication Circuits
For lubrication systems in industrial gearboxes or compressors that run around the clock, this filter's 10 bar collapse pressure withstands pressure spikes during cold starts or system surges, reducing maintenance downtime.
Mobile Equipment Fluid Filtration
On mobile plant equipment such as excavators or loaders, the compact 145 mm height and 95.5 mm diameter allow installation in tight engine bays. The wire mesh media is cleanable, extending service intervals in dusty environments.
Inventory Consolidation for Multi-Brand Fleets
Fleet managers maintaining mixed-brand equipment can stock this filter as a single replacement for filters from ASC, Fai Filtri, Napa, Quincy, and others, simplifying inventory and reducing stock holding costs.
Frequently asked questions
How can I confirm this filter fits my equipment?
Verify your existing filter's thread size is UNF 1 inch female bottom, total height 145 mm, and outer diameter 95.5 mm. Cross-reference your part number with brands such as Baldwin, Donaldson, Fleetguard, or WIX. If your filter matches these dimensions and thread, this filter is a direct replacement.
What is the filtration rating and media type?
The filter uses a 90 µm wire mesh media. This rating is suitable for systems requiring coarse filtration, such as return-line or low-pressure applications, where capturing larger particles is critical.
What are the thread specifications and overall dimensions?
The thread is UNF 1 inch female bottom (12 threads per inch). Total height is 145 mm, outer diameter is 95.5 mm. Ensure your filter head accommodates a female bottom thread of this size.
Is this filter OEM or aftermarket, and how does it compare?
This is an aftermarket filter built to the original dimensions and ratings. It is a direct replacement for brands like Baldwin, Donaldson, and Fleetguard, offering comparable performance at a lower price. It is not a genuine OEM part.
How do I install this filter?
Installation is straightforward: screw the filter onto the filter head by hand until the gasket contacts, then tighten an additional 3/4 turn. Do not use a filter wrench to overtighten. Always replace the O-ring if present.
