DONALDSON TOPSPIN PRECLEANER REDESIGNED TO
WITHSTAND GREATER VIBRATION AND EXTEND BEARING LIFE

Halts debris and chaff from entering the intake during harvesting

How It Works
The Donaldson TopSpin™ draws in dirty air, forcing the pre-filtered clean air into the air inlet and automatically ejecting mixed debris out the side of the unit. It is self-ejecting and self-scavenging, so it never has to be emptied or cleaned.

Superior Filtration Performance
The Donaldson TopSpin™ separates up to 85 percent of all incoming contaminants and more than 99 percent of particles 20 microns and larger, reducing air filter usage and greatly extending filter life. The TopSpin™ continues to work at engine idle, cleaning the incoming air even when the equipment is not moving. Pre-filtering incoming air provides lower restriction, improving engine performance and reducing filter costs. The TopSpin™ has a range of 90 - 1600 cubic feet per minute (CFM).

TopSpin™ vs. Dust Bowl
The TopSpin™ provides many advantages over the traditional dust bowl-style pre-cleaners. Dust bowl technology collects contaminants and cannot pre-clean the air when it reaches capacity. Donaldson TopSpin™ pre-cleaners continuously eject contaminants, providing continuous and consistent pre-cleaning.

Dust bowls require frequent dumping and cleaning, and create ongoing expenses for customers forced to continually replace damaged bowls. The TopSpin™ installs quickly and easily with only one clamp to tighten. It requires no dumping and no cleaning.

Solid Construction
The Donaldson TopSpin™ features a robust design. Its dual mounted bearings are sealed for extended life, and they allow the scavenging blades to spin quietly, continually cleaning the TopSpin™ and ejecting contaminants.

First introduced in December of 2001 with just 2 sizes, Donaldson’s popular TopSpin line of pre-cleaners is now available in 13 models, with outlets ranging from 2″ to 7″ and air flow ranges from 100 cubic feet per minute (cfm) to 1600 cfm. Since its introduction, Donaldson TopSpin has demonstrated the ability to extend air filter life and boost overall system efficiency and performance by automatically separating and discarding contaminants and debris prior to primary air filter intake.

The innovative, clear-view, self-cleaning design of Donaldson TopSpin air intake system pre-cleaners keeps pace with the rapid changes in vehicle operating requirements. TopSpin separates up to 99% of large debris and 85% of coarse air contaminants – one of the most efficient devices in the market – reducing engine wear and overall operating costs.
