Donaldson TopSpin™ Pre-Cleaners will extend air filter life, reducing filter expenses and overall operating costs. The aerodynamically designed TopSpin is made of a lightweight, durable, non-corroding material which makes it tolerant to all weather and operating conditions. The Donaldson TopSpin Pre-Cleaner has the lowest restriction of any competitive brands tested. Lower restrictions means:
SCFM = Standard Cubic Feet per Minute
- Engine can "breath" easier
- Air filter usage is reduced
- Lower costs per operating hour
- More dust loaded on the filter when serviced by restriction
