Donaldson Company has introduced ArmorSeal, a next-generation air filtration technology designed to improve seal integrity and durability in heavy-duty, construction and off-highway applications.

The Minneapolis-based manufacturer says the new system builds on its legacy Axial Seal and RadialSeal technologies, targeting equipment operating under high vibration, heavy dust loads, and frequent service cycles.

Donaldson says the ArmorSeal technology integrates a precision spin-welded joint, eliminating common failure modes through a uniform, repeatable spin-welded joint in place of snaps and adhesives, with a geometry-based engineered seal interface, which prevents micromovement, debris intrusion, and improper installation, lowering filter removal force by 30% compared to current RadialSeal technology.

According to a news release, the technology is designed for compatibility with multiple air cleaner architectures, including Donaldson’s legacy FPG platform. It is also engineered for automated manufacturing and global production consistency, with validation through modeling and OEM durability testing.

“Unplanned downtime remains one of the biggest cost drivers for equipment owners, and effective air filtration plays a critical role in reducing it,” said Mark Sala, director of air product management, in the release. “The ArmorSeal technology was created to eliminate the variability and failure modes we’ve historically seen in high vibration, dusty environments. It delivers a more robust, user-friendly, and reliable air filtration solution that directly supports equipment uptime.”
