An experimental program was conducted to evaluate applicability of the fan-airpump concept as applied to military air cleaner systems and vehicles. Technical feasibility and potential use were evaluated through laboratory testing which defined fan-airpump performance characteristics and investigated the performance envelope of the fan-airpump concept when applied to the 2-12 and 5-ton truck. Economic feasibility was assessed by comparing projected fan-airpump life cycle cost factors with similar cost factors associated with blower motor systems. Because it has no moving part, requires no lubrication, and is practically maintenance, free, the use of a fan-airpump to develop the scavenge flows required by two-stage air cleaner systems would alleviate the problems caused by unreliable blower motors or marginal exhaust aspirator replacements. As a result, the fan-airpump could become a major component for improving reliability and operational readiness for many vehicles operating with two-stage air cleaner systems.
