The Donaldson Cyclone 70 air pre-cleaner is engineered to extend primary filter life by efficiently removing up to 90% of airborne dust and contaminants before they reach the engine's air intake. This self-powered unit utilizes engine air intake vacuum to spin a rotor, separating heavier dust particles which are then discharged through a scavenger port. It is ideal for agricultural, construction, and mining equipment operating in severe dusty conditions, significantly reducing maintenance frequency and operating costs by protecting critical engine components.
