摘要：
The present invention provides a filtering medium for an air filter which has a greatly increased dust retention amount while maintaining high collecting efficiency, a filter pack, an air filter unit, and a method for producing the filtering medium for an air filter. The filtering medium for an air filter of the present invention is provided with a first porous membrane and a second porous membrane mainly composed of a fluororesin. The second porous membrane is disposed on the downstream side of airflow compared to the first porous membrane. The first porous membrane has a dust retention amount of the polyalphaolefin particles when the air containing polyalphaolefin particles with a count median diameter of 0.25 µm is continuously passed through at a flow rate of 5.3 cm/sec, which is larger than that of the second porous membrane. The filtering medium for an air filter has a pressure loss of less than 200 Pa, a collecting efficiency for NaCl particles with a particle diameter of 0.3 µm is 99.97% or more, and the dust retention amount for the polyalphaolefin particles with a count median diameter of 0.25 µm is 25 g/m 2 or more.
摘要（中）：
本发明提供一种用于空气过滤器的过滤介质，其具有同时保持高的集电效率，过滤器包以空气过滤器单元大大增加的尘埃滞留量，以及用于制造用于在空气过滤器过滤介质的方法。 在本发明的空气过滤器的过滤介质被设置有第一多孔膜和主要由氟树脂构成的第二多孔膜。 第二多孔膜设置在相比于第一多孔膜的空气流的下游侧。 所述第一多孔膜具有聚α-烯烃颗粒当含有聚α-烯烃颗粒的0点25微米的计数中值直径的空气连续地通过在5.3cm /秒的流速通过的尘埃滞留量，在所有这比第二多孔的较大 膜。 在空气过滤器的过滤介质具有小于200帕，对于具有0.3微米的颗粒直径的NaCl颗粒的收集效率为99.97％以上的用于与计数中值直径的聚α-烯烃颗粒的压力损失，且尘埃滞留量 的0:25微米为25g / m 2以上。
