折(zhe)疊濾芯的接口(kou)形(xing)式(shi)(shi)根據其(qi)具(ju)體形(xing)狀(zhuang)和結構進行(xing)分(fen)類，如(ru)翅片(pian)型(xing)(xing)(xing)(xing)(xing)(xing)(xing)(xing)（8字型(xing)(xing)(xing)(xing)(xing)(xing)(xing)(xing)）、三角翅片(pian)型(xing)(xing)(xing)(xing)(xing)(xing)(xing)(xing)、平面型(xing)(xing)(xing)(xing)(xing)(xing)(xing)(xing)（平封(feng)型(xing)(xing)(xing)(xing)(xing)(xing)(xing)(xing)和非(fei)平封(feng)型(xing)(xing)(xing)(xing)(xing)(xing)(xing)(xing)）等。而折(zhe)疊濾芯的插口(kou)類型(xing)(xing)(xing)(xing)(xing)(xing)(xing)(xing)則(ze)包(bao)括226型(xing)(xing)(xing)(xing)(xing)(xing)(xing)(xing)或(huo)不(bu)(bu)銹(xiu)鋼226型(xing)(xing)(xing)(xing)(xing)(xing)(xing)(xing)（卡(ka)入(ru)式(shi)(shi)）、222型(xing)(xing)(xing)(xing)(xing)(xing)(xing)(xing)或(huo)不(bu)(bu)銹(xiu)鋼222型(xing)(xing)(xing)(xing)(xing)(xing)(xing)(xing)（插入(ru)式(shi)(shi)）、220型(xing)(xing)(xing)(xing)(xing)(xing)(xing)(xing)（插入(ru)式(shi)(shi)）、215型(xing)(xing)(xing)(xing)(xing)(xing)(xing)(xing)（插入(ru)式(shi)(shi)）、M30螺(luo)紋型(xing)(xing)(xing)(xing)(xing)(xing)(xing)(xing)（旋轉式(shi)(shi)）、M36螺(luo)紋型(xing)(xing)(xing)(xing)(xing)(xing)(xing)(xing)（旋轉式(shi)(shi)

折(zhe)疊濾(lv)(lv)芯的尺寸，這(zhe)通常取決于其(qi)接口類(lei)型和具體規格。226接口的折(zhe)疊濾(lv)(lv)芯，其(qi)內徑約(yue)(yue)為43.9mm，外徑約(yue)(yue)為56.5mm，含O型圈(quan)(quan)外徑約(yue)(yue)為58.7mm；而(er)222接口的折(zhe)疊濾(lv)(lv)芯，其(qi)內徑約(yue)(yue)為32.1mm，外徑約(yue)(yue)為44.3mm，含O型圈(quan)(quan)外徑約(yue)(yue)為45.5mm
