Clean hydraulic fluid is essential to long equipment life. With proper filtration, contaminants are removed before they cause wear, efficiency loss, or unplanned downtime. Donaldson’s industry‑leading hydraulic filters ensure superior fluid cleanliness—protecting critical components and keeping your equipment performing at its best. 

Our hydraulic portfolio consists of two advanced filtration tiers: Donaldson OEM-grade and Donaldson Blue® high-performance. 

Donaldson OE-Grade Hydraulic Filters

Designed to meet or exceed OEM requirements, Donaldson standard hydraulic filters deliver dependable protection for everyday operating conditions. They are ideal for equipment running predictable duty cycles and standard service intervals. 

Key advantages include: 

• Cellulose and synthetic media options for reliable contaminant capture, supporting efficient system flow  
• Rugged construction built for modern hydraulic pressures 
• Cost-effective with consistent protection for both legacy and new equipment  

Donaldson Blue® High Performance Hydraulic Filters

For demanding applications, Donaldson Blue® filters elevate performance with premium Synteq™ and AlphaWeb™ fine fiber media technologies engineered to deliver industry-leading hydraulic fluid cleanliness.   

Advanced media benefits include:
