Donaldson BIOAdvantage™ High Efficiency Particulate Air (HEPA) filters are extremely efficient in removing both smaller particles (smoke, atmospheric dust, microbiological material) and larger ones (lint, pollen). Donaldson BIOAdvantage™ HEPA filters with antimicrobial additives take contamination control to the next level by disabling bacteria, spores, fungus, and other microbial aerosols trapped by the filter media. Learn more about BIOAdvantage.

Air Purification Systems™ (APS) The Donaldson APS is designed to help improve cabin air quality and passenger and flight crew comfort. Donaldson’s latest advancement in filtration technology is extremely efficient at removing gaseous irritants and odors from the aircraft cabin as well as allergens, bacteria and viruses.

Inertial Particle Separator Systems with Strata® Tubes Air particle separators with Donaldson’s specially designed Strata® tubes spin contaminants out of incoming air, providing reliable, low maintenance air filtration for every space requirement and performance level.
|

|
Barrier Filters and Air Cleaners Barrier filters like Vee-Pacs, round, Konepac™ conical and panel filters meet stringent efficiency, weight and space requirements. We have more than 50 years of experience designing and supplying barrier filters and air cleaners for aircraft and military vehicles requiring high performance filtration.

Donaldson PowerCore® Filtration Technology With more streamlined designs, stricter exhaust emissions regulations and increased horsepower, today’s heavy equipment and vehicles are running hotter in a more confined amount of space. To meet demands for a compact, high-performance air filtration solution, consider PowerCore. As an alternative to larger-sized conventional filters, PowerCore’s straight-through airflow and high-density filtration system reduces system restriction and extends filter life, reducing overall maintenance costs. Learn more about PowerCore.

Donaldson Ultra-Web® Nanofiber Filtration Nanofiber filtration causes submicron contaminant to load on the surface of a filter rather than dispersing throughout the depth of the filter media where there is less area for the air to flow. Ultra-Web filters hold up to five times more contaminants than cellulose filters. Ultra-Web filtration provides superior engine protection and is ideal for extending filter service intervals.

|
Pulse Jet Air Cleaners (PJAC™) PJAC is a self-cleaning filtration system for the most demanding environmental conditions giving you optimal reliability and reduced fuel consumption. The PJAC engine filtration system automatically cleans the filters, removing contaminants away from the engine.
