SO-633C SEPARATOR AVIATION FUEL FILTER CARTRIDGE (6TH EDITION)

SEPARATOR CARTRIDGES ARE EMPLOYED AS THE SECOND STAGE IN FILTER/ SEPARATOR VESSELS. THEIR SOLE FUNCTION IS TO REPEL COALESCED WATER DROPS PRODUCED BY THE FIRST STAGE CARTRIDGES WHILE ALLOWING HYDRO-CARBON FLUIDS TO PASS THROUGH. WATER DROPS SETTLE INTO THE FILTER/ SEPARATOR SUMP AND ARE NOT CARRIED DOWNSTREAM. ALL PARTICLE FILTERING IS DONE BY THE FIRST STAGE COALESCER CARTRIDGE.
