Two prototype Microstructured Oriented Fiber MOF air filter elements were designed and built to fit a HMMWV M998 Utility Truck multi-stage housing by MicroEnergy Technologies Inc. under contract DAAE07-03-C-L066. During April and May of 2003, the MOF filters underwent dust capacity and efficiency performance testing at the U.S.Army Tank Automotive Research, Development and Engineering Center TARDEC. The MOF filter did not meet the efficiency or dust capacity performance requirements. The MOF filter attained an efficiency of 66.78, which is far lower than the required 99.5. The MOF filter achieved a dust capacity of 40 minutes, which is considerably less than the required 20 hours. During the efficiency and dust capacity testing, the pressure drop across the master absolute filter increased rapidly which indicated the MOF filter was allowing a significant amount of dust to pass through resulting in low performance. The MOF filter is not recommended for the M988 since the dust capacity and initial efficency did net meet the performance requirements.
