Donaldson Company, Inc., a global leader in filtration solutions, has announced the launch of its next-generation air filtration technology, ArmorSeal™. The ArmorSeal technology is designed to address the challenges faced by industries operating heavy equipment, such as construction, mining, and off-road, by providing a more robust, user-friendly, and reliable air filtration solution that supports equipment uptime.

Why it matters

As off-highway, construction, and heavy-duty equipment continue to operate in more demanding environments with higher vibration, dust loads, and frequent service cycles, maintaining long-term seal integrity has become a persistent challenge. The ArmorSeal technology directly addresses this issue, delivering a step-change in reliability, durability, and service consistency to help reduce unplanned downtime, a major cost driver for equipment owners.

The details

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. This design maintains controlled sealing pressure over time while reducing service force and installation variability. The ArmorSeal technology is engineered for automated manufacturing, global repeatability, and long-life performance, validated through advanced modeling and OEM durability testing.

  • The ArmorSeal technology will make its official debut at CONEXPO-CON/AGG in 2026.
