The structural limits of HEPA filters subjected to pressure transients caused by abnormally large air flows were measured. The purpose of this test was to obtain the basic data to estimate the safety of HEPA filters. The large air flow was generated by the release of pressurized air in the tank. The filters were subjected to pressure transients uniformly and in the filter unit which was similar to actual equipment.
The pressure on the filters was proportional to the air flow rate till around 200 m³/min, and above this flow rate the high increasing rate of pressure was observed. The structural limits of the filters were estimated to be 9.518 kPa. Under pressure transients the smaller the particle was, the lower the decontamination factor (DF) was. The DF for particles over 0.3 μm in diameter did not drop.
The flow rate at the structural limit of the filters in the filter unit was lower than that of the filters uniformly subjected to pressure transients because of the partial flow in the filter unit.
