Donaldson Company's TopSpin HD Heavy-Duty Pre-Cleaners benefit from being built for high-dust and heavy-debris environments, such as mining, construction, oil and gas and agriculture. Its high efficiency design delivers low restriction and enables it to separate and eject up to 80 percent of incoming contamination before it can reach the engine's air cleaner. It also helps prolong air filter life, which results in less frequent air filter replacement, lower operating costs, and less maintenance downtime. Offered in eight sizes, so the end user can choose one that is appropriate for their air filtration system.
