Air treatment units (also called air preparation units) don’t do any job 

directly like pneumatic cylinders and solenoid valves, however, they’re 

playing an very important role as pre-treating air source from air 

compressor, which make big influence of how long pneumatic cylinder and 

solenoid valves can work, including air filter, air regulator and air 

lubricator. To meet wide industry fields application, E.MC provides 

multiple design for FRL, including E series air treatment units, with very 

dependable and stable quality for over 20 years, EI series FRL with gauge 

integrated inside body, space saving, FE series European type FRL, very  

high acceptance in Europe and other countries, equivalent to Festo, HE 

series environment protective FRL, HNE series metal bowl FRL, AE/BE series 

economic FRL, EN series compact FRL, pressure switch, auto drain, high 

precision regulator, all etc. Especially the updated E/EI series FRL, with 

E.MC engineers deep study, test and special body design, it supports more 

than 9 Bar in actual application while normal FRL oilers break for long 

time use, which proves top technology in FRL field and give a better air  

source solution for higher pressure demanded fields.
