Donaldson has expanded its lineup of TopSpin self-cleaning air intake system pre-cleaners to 13 models. Although appropriate for a variety of applications, the TopSpin line is particularly well suited for vocational trucks operating in environments such as logging, where they encounter heavy dust or grass conditions, said the manufacturer.

TopSpin extends air filter life and boosts overall system efficiency and performance by automatically separating and discarding contaminants and debris prior to primary air filter intake. According to Donaldson, the system separates 99% of large debris and 85% of coarse air contaminants to reduce engine wear and overall operating costs.
