一、油氣分離器濾芯
油氣分離元件是決定空壓機壓縮空氣品質的關鍵部件，高質量的油氣分離元件不僅可保證壓縮機的高效率工作，且濾芯壽命可達數(shù)千小時。從壓縮機頭出來的壓縮空氣夾帶大大小小的油滴。大油滴通過油氣分離罐時易分離，而小油滴（直徑1um以下懸浮油微粒）則必須通過油氣分離濾芯的微米及玻纖濾料層過濾。油微粒經過濾材的擴散作用，直接被濾材攔截以及慣性碰撞凝聚等機理，使壓縮空氣中的懸浮油微粒很快凝聚成大油滴，在重力作用下油集聚在油分芯底部，通過底部凹處回油管進口返回機頭潤滑油系統(tǒng)，從而使壓縮機排出更加純凈無油的壓縮空氣。壓縮空氣中的固體粒子經過油分芯時滯留在過濾層中，這就導致了油分芯壓差（阻力）不斷增加。隨著油分芯使用時間增長，當油分芯壓差達到0.08到0.1Mpa時，濾芯必須更換，否則增加壓縮機運行成本（耗電）。
二、空氣過濾器濾芯
空壓機空氣濾芯用于空壓機進氣口處，除去空氣中的固體顆粒，保證系統(tǒng)清潔要求，空氣過濾器是濾除空氣塵埃污物的部件，過濾后的干凈空氣進入螺桿轉子壓縮腔壓縮。因螺桿機內部間隙只允許15u以內的顆粒濾出。如果空濾芯堵塞破損，大量大于15u的顆粒物進入螺桿機內循環(huán)，不僅大大縮短機油濾芯、油細分離芯的使用壽命，還會導致大量顆粒物直接進入軸承腔，加速軸承磨損使轉子間隙增大，壓縮效率降低，甚至轉子枯燥咬死。
