Donaldson TopSpin pre-cleaner air filters
extend primary air filter life, boost system efficiency and extend
engine life in all off-road heavy-duty applications, such as farm
equipment, backhoes, dozers and more.
Self-Ejecting Pre-Cleaner Air Filter Maximizes
Air Intake Systems
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 - 1500 cubic feet per
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.
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.
