The Donaldson PBH001250 TopSpin pre-cleaner is an essential component designed to significantly extend the life of air filters by removing up to 99% of airborne dust and dirt before it reaches the main filter. This self-cleaning, low-profile unit operates without a scavenge line, reducing maintenance and downtime. It features a 127 mm (5-inch) connection diameter and is suitable for air flows between 17-28 m³/min (600-1000 CFM). Constructed from durable, lightweight, and corrosion-resistant polypropylene, it ensures reliable performance in demanding agricultural and construction environments. The pre-cleaner mounts directly on the air intake pipe.
