The Donaldson Primary Round Air Filter for Atlas is an air filter designed specifically for heavy duty engine applications. Its round shape and axial seal filter type make it ideal for use in Atlas Copco equipment. The filter is made from strong and pliable gasket material that creates a tight seal against the air cleaner housing. This ensures that only clean air is delivered to your engine, which can help to extend its life and improve its performance. The high-efficiency cellulose media used in this filter is capable of performing across a wide range of heavy duty engine applications. This makes it a versatile and reliable choice for any job. In addition, the filter has more media pleats than standard air filters, which gives it a higher dust holding capacity and longer filter life. The Pleatloc feature ensures uniform pleat spacing and prevents media from bunching, promoting longer service life and better performance. FleetPride is your First Click in Heavy Duty®.
