The Donaldson Company has launched ArmorSeal, its next‑generation air filtration technology.
The ArmorSeal technology builds on decades of Donaldson leadership in air filtration, from Axial Seal to the industry-defining RadialSeal and now to a new standard designed for today’s most demanding operating environments.
As off‑highway, construction, and heavy‑duty equipment continue to operate under higher vibration, higher dust loads, and more frequent service cycles, maintaining long-term seal integrity has become one of the industry’s most persistent challenges.
The ArmorSeal technology addresses this challenge directly, delivering a step-change in reliability, durability, and service consistency.
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.
The company’s director of air product management, Mark Sala, said this design maintains controlled sealing pressure over time while reducing service force and installation variability.
“Unplanned downtime remains one of the biggest cost drivers for equipment owners, and effective air filtration plays a critical role in reducing it,” Sala said.
“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.”
Industries operating heavy equipment including construction, mining, and off-road face growing pressures to extend machine life while minimising downtime.
Once contaminants bypass the air filtration system, performance degrades rapidly and engine damage can follow. The ArmorSeal technology directly responds to these challenges.
Building on the legacy of RadialSeal technology, the ArmorSeal design redefines expectations for modern air filtration systems. It is engineered for automated manufacturing, global repeatability, and long‑life performance, validated through advanced modelling and OEM durability testing.
Founded in 1915, Donaldson has employees at over 150 locations on six continents.
