Liquid Filtration

When your liquid filters are right, you know you’ve got peak engine and equipment performance. Today’s equipment is built to more stringent specifications and finer tolerances. Donaldson and Le Bozec deliver innovative designs, a complete product line, and performance that meets or exceeds original equipment manufacturers’ specifications. More details are available in our Product Literature and Application Overview sections.


Coolant Filters
Rust. Scale. Debris. Your engine battles them. And when it loses, you pay. Your cooling system keeps engine temperatures at the right level to dissipate heat and maintain the right operating conditions for optimal fuel economy. Donaldson coolant filters remove contaminants, minimize the risk of filter plugging and keep your engine running efficiently. Balance is the key in Coolant Filtration.

Fuel Filters
Fuel systems, pumps, and injectors require cleaner fuel to achieve better combustion and lower emissions. That’s why the latest advances in filter media can make the difference between power and problems.
• Ice Tolerant Liquid Filters
• Coalescing Filters
• Strainers
• Re-Fueling Systems
• Fuel Filter Water Separators (FFWS)
• Landing Gear Brake Fluid Filters

Hydraulic Filters
Donaldson develops, manufactures, and markets a full line of industrial and mobile hydraulic filters for the protection of machinery and components in hundreds of applications – in the factory and on heavy-duty mobile equipment.

When you need filter housings, filter heads, replacement cartridges, spin-ons (e.g., Donaldson Duramax®), or hydraulic accessories, turn to Donaldson and Le Bozec.

Lube/Oil Filters
Donaldson and Le Bozec filters, strainers, valves, regulators and demisters provide protection of fluid circuits on aircraft and rotorcraft. Donaldson also provides a popular spin-on oil filter adapter for Lycoming engines – for the 320, 340, 360, 540 & 720 series engines.

Transmission Filters
With decades of experience in heavy equipment, engine and exhaust filtration, Donaldson and Le Bozec products are found throughout the aviation industry, not just inside planes.
