Our company founder, Frank Donaldson, designed and built the first effective air filter for a heavy-duty engine in 1915. Since then, nearly every significant innovation in air cleaner technology has been led by Donaldson.
When you choose Donaldson air filters, you get performance that's anything but standard.
We offer a wide range of air filters for every need:
RadialSeal™ Filters
- Create a superior seal and vibration-resistant interface between the air cleaner and the filter
- This reliable seal helps to protect engines in extreme operating conditions
- Offering replacement filters for Donaldson air cleaners – and for many competitive air cleaners
Axial Seal Filters
- Traditional filter design with a gasket on the end of the filter that gets compressed against the housing to create a tight seal
- Our filters have a strong, pliable gasket that ensures a leak-free seal when properly installed
- Our gaskets won't harden or deteriorate over the life of the filter
Features
- Heavy-duty liners – corrosion-resistant, coated steel liners support the media during operation and help maximize airflow
- Pleatloc™ media spacing – ensures uniform pleat spacing, which keeps filter media from bunching and promotes longer service life
- Beading – applied to filter liners, beading is designed to stabilize media and prevent pleat tip wear
Benefits
- Donaldson-branded filters are designed specifically to give you effective, consistent performance over the life of your engine
- The company that invented air filters for heavy-duty engines to deliver the broadest vehicle and equipment coverage, the most consistent quality and the best overall performance
Applications
- On-road trucks, Off-road trucks, and equipment
Available Media Types
- Cellulose – standard media used in the majority of air filter applications
- Flame-retardant and vibration-resistant cellulose media variations available to meet specialty engine applications requirements
PowerCore Air Filters
Don’t take a chance on engine protection. Donaldson’s breakthrough PowerCore® air filters have been delivering superior performance and meeting original equipment manufacturer (OEM) specifications for more than 20 years.
In that time, PowerCore air filters have logged billions of on-road miles and off-road hours, protecting engines, reducing downtime, and saving money for fleet operators. Donaldson PowerCore air filters continue to set new standards in filtration quality, coverage, and performance, with smaller and lighter air cleaners driven by increasingly more stringent emissions regulations, and airflow designs that deliver superior efficiency and dust-holding capacity.
Features
- Smaller and lighter to meet evolving emissions regulations (and greater emissions system space claim)
- Better dust-loading – extending filter life with 13-26% more contaminant-loading capacity*
- Better initial restriction – protecting performance with 27-49% lower initial restriction*
- Metal-free, lightweight filters
- Unique shapes, the ability to design a wide range of shapes and sizes
- Improved contaminant encapsulation, dust and dirt stay contained in the filter during service
- Straight-through airflow design delivers better overall efficiency and better dust-holding capacity than other filter configurations
Benefits
- Effective, consistent performance for the life of your engine
- Greater filter capacity means longer filter life, which means fewer filter changes and less money spent on maintenance
- Lower initial restriction protects engine performance and fuel economy
- Designed specifically to give you effective, consistent performance over the life of your engine
Applications
- On-road trucks, Off-road trucks, and equipment
Available Media Types
- Cellulose – standard media used in the majority of air filter applications
- Ultra-Web – filtration media technology featuring very fine, resilient fiber
- Flame-retardant media variations available to meet specialty engine applications requirements
