The heavy-duty Donaldson B085001 DuraLite Primary Air Cleaner serves as an incredibly durable and reliable line of defense for small-to-midrange stationary and mobile systems. Designed out of rugged ABS plastic, this non-corrosive housing holds a vibration-resistant pleated cellulose media potted directly into the structural caps. This design completely eliminates internal bypass leaks and ensures high structural integrity against the severe intake back-pulses common in two- and three-cylinder engines or industrial air systems.
Because it operates as a unified, one-piece component, maintenance is exceptionally straightforward—there are no individual inner seals or separate structural covers to service. Once the filter reaches its maximum dirt-holding capacity, the entire lightweight unit is simply swapped out, completely eliminating the risk of raw dust bypass contamination during servicing intervals. Its high temperature tolerance up to 180°F (83°C) continuous makes it perfect for intense heavy-duty applications ranging from mobile gen-sets and welding rigs to industrial plant air compressor packages.
