长期供应颇尔滤芯UE619AN20H，打折结构过滤面积大，起始压差低，流速快，过滤器容积小，造价成本小。由于是预过滤和终过滤合二为一，因此滤芯容污能力非常大。使用寿命比单一孔径的滤芯长。单一的纯聚丙烯材质，易判断其化学兼容性。四海滤清器厂有经验生产PALL颇尔滤芯UE219，UE319系列和UE619系列滤芯，四海采用进口优异玻璃纤维材质，过滤精度分别为：3，5，7，12，22微米。四海保证滤芯的规格及尺寸。完全替代PALL颇尔滤芯。具体型号如下：UE619AZ20H UE619AZ20Z UE619AZ40H UE619AZ40Z UE619AP20H UE619AP20Z UE619AP40H UE619AP40Z UE619AN20H UE619AN20Z UE619AN40H UE619AN40Z UE619AS20H UE619AS20Z UE619AS40H UE619AS40Z UE619AT20H UE619AT20Z UE619AT40H UE619AT40Z UE219AZ08H UE219AZ08Z UE219AZ13H UE219AZ13Z UE219AZ20H UE219AZ20Z UE219AZ40H UE219AZ40Z UE219AP08H UE219AP08Z UE219AP08H UE219AP13H UE219AP13Z UE219AP20H UE219AP20Z UE219AP40H UE219AP40Z UE319AN08H UE319AN08Z UE319AN13H UE319AN13Z UE319AN20H UE319AN20Z UE319AN40H UE319AN40Z UE319AS08H UE319AS08Z UE319AS13H UE319AS13Z UE319AS20H UE319AS13Z UE319AS20H UE319AS20Z UE319AS40H UE319AS40Z UE319AT08H UE319AT08Z UE319AT13H UE319AT13Z UE319AT20H UE319AT20Z UE319AT40H UE319AT40Z UE619AZ20H UE619AZ20Z UE619AZ40H UE619AZ40Z UE619AP20H UE619AP20Z UE619AP40H UE619AP40Z UE619AN20H UE619AN20Z UE619AN40H UE619AP40Z UE619AS20H UE619AS20Z UE619AS40H UE619AS40Z UE619AT20H UE619AT20Z UE619AT40H UE619AT40Z等
