SMC三聯件即F.R.L是將空氣過濾器（F）、減壓閥（R）和油霧器（L）三種氣源處理元件組裝在一起稱為三聯件，還可以與氣動變送器，氣動調節器等產品安裝在一起配套使用。可過濾壓縮空氣中的水份，避免水份隨氣體進入裝置。油霧器可對機體運動部件進行潤滑，可以對不方便加潤滑油的部件進行潤滑，大大延長機體的使用壽命。整體的作用是用以進入氣動儀表之氣源凈化過濾和減壓至儀表供給額定的氣源壓力，相當于電路中的電源變壓器的功能。

3/8,1/2,3/4 | 0.05~0.7、0.02~0.2 |
| 過濾減壓閥、油霧器 | AC10A~40A-A |
| 過濾器、減壓閥 | AC10B~40B-A |
| 過濾器、油霧分離器、減壓閥 | AC10C~40C-A | 1/8,1/4,
3/8,1/2,3/4 |
| 過濾減壓閥、油霧分離器 | AC10D~40D-A |
·可操作性提高濾芯和外殼一體化，可以手動更換濾芯。
·節能減壓閥,壓力降：zui大改善50%
·減少維護空間,zui大減少46%
·便于目視確認，安全性提高。
·透明外殼保護罩提供全面保護。
SMC三聯件安裝事項：
1、安裝時請注意清洗連接管道及接頭，避免臟物帶入氣路。
2、安裝時請注意氣體流動方向與本體上箭頭所指方向是否一致，注意接管及接頭牙型是否正確。
3、過濾器、調壓閥（調壓過濾器）給油器的固定；將固定支架的凸槽與本體上凹糟匹配，再用固定片及螺絲鎖緊即可。
4、單獨使用調壓閥、調壓過濾器時的固定；旋轉固定環使之鎖緊附帶的固定片即可。
