贺德克滤芯是输送介质的管道系列中不可缺少的部分，通常安装在液压系统的进口端过滤中，用来滤除流体介质中的金属颗粒、污染杂质等，可保护设备的正常工作，当流体进入过滤器后，其杂质被阻挡，而清洁的滤液则由过滤器出口排出。当需要清洗时，只要将滤芯从过滤器中取出，用工业液体处理后装入即可。
贺德克滤芯产于德国贺德克(HYDAC Technology GmbH)公司。公司致力于科研开发流体过滤技术、液压控制技术、电子测量技术的元件和装置，是世界过滤器、蓄能器、液压阀、电子产品、管夹、电磁铁、液压系统总成等产品的液压件的制造。进口液压滤芯
1.该滤芯采用美国进口玻纤/不锈钢网制成，具有排污方便、流通面积大、压力损失小，结构简单，体积小，重量轻、过滤材质均匀等。
2.滤材的兼容性适用于一般液压油的过滤。
3.滤芯由两侧的固体滤料和稳定性较强的过滤材料做支撑，符合ISO3724/76液压滤芯流动疲劳特性的验证。
