WD 13 145 Hydraulic Oil Filter
High-Pressure Spin-On for Air Compressors and Paving Equipment
Captures 37-micron contaminants to protect sensitive hydraulic circuits and screw elements.
Robust cellulose media with a 20 bar collapse burst rating for heavy industrial cycles.
Integrated 36 psi (2.5 bar) valve ensures continuous lubrication during cold starts.
12.13-inch (308 mm) canister provides superior dirt-holding volume for long service.
Technical Deep-Dive: Industrial Grade Protection
Advanced Filtration for High-Demand Systems
In heavy-duty applications like Sullair air compressors and Caterpillar paving equipment, hydraulic oil must remain free of abrasive particulates to prevent pump cavitation and valve sticking. The WD 13 145 utilizes premium cellulose media that is chemically stable against modern synthetic and mineral-based oils.
Why Choose the WD 13 145 Replacement?
- ISO 16889 Compliance: Tested under rigorous international standards to guarantee consistent filtration performance across its entire lifecycle.
- Zero-Leak Seal: The high-precision 1 1/2-16 UN threading and custom-fit gasket (111 mm OD) ensure a vacuum-tight seal even under extreme thermal expansion.
- Versatile Cross-Compatibility: Replaces high-cost OEM units from Atlas Copco, Aerzen, and Alup, providing a cost-effective solution without sacrificing technical integrity.

Maintenance FAQ
Q: Is the WD 13 145 suitable for Caterpillar paving equipment?
A: Yes, it is specifically designed for Caterpillar RM, PM, and PS series paving and milling equipment.
Q: What is the benefit of the 37-micron 99% efficiency rating?
A: It ensures that nearly all particles larger than 37 microns are removed, preventing wear on high-pressure hydraulic pumps.
Q: Can this replace Atlas Copco 6211473500?
A: Absolutely. The WD 13 145 is a direct technical equivalent to the Atlas Copco 6211473500.
Q: Why does this filter have a bypass valve?
A: The 2.5 bar bypass valve allows oil to flow if the filter is clogged or during cold starts when oil is too thick to pass through the media.
