Spin-on Lube/Oil Filters
Donaldson durable lube filters keep your equipment running at its best to let you focus on what’s most important, getting your job done.

Full-flow Filters
Full-flow lube filters are designed to keep the oil clean by removing contaminant. On most engines, a full-flow filter is all you need to lubricate engine components.

By-pass Filters
When used, a by-pass filter continually circulates approximately 10% of the oil in the lubricating system. By-pass filtration supplements the full-flow filter with the capability to remove smaller contaminant.

Cartridge-style Filters
Donaldson offers a complete line of cartridge-style lube filters for all makes of equipment.

For more information Donaldson spin-on, full-flow by-pass or cartridge-style filters, review our liquid filter Product Literature section.
