How CENTRI ® Air Precleaners cut costs!
1. Dirty air enters the CENTRI ® which is clamped onto your equipment’s air intake pipe.
2. Specially designed vanes, curved and angled to precisely direct air flow, move the dirty air toward the stainless steel impeller.
3. The dynamically balanced, one piece spinning impeller (the only moving part) creates a tornado inside the housing.
4. The centrifugal force of the tornado expells the heavier-than-air dirt particles, chaff, dust, snow, rain, etc., out the discharge louver.
5. Cleaned air enters the engine intake pipe, and the filter element has only the very light particles to remove.
