OS Series Coalescer/Separator Cartridges
for Aviation Fuels

OS-51288	OS-60988

The OS Series combination coalescer/separator cartridges filter dirt and remove water from aviation fuels. Designed for superior performance in VF-61 & VF-609 Housings, Facet's VFCS-21 & VFCS-22 Filter/Separator Vessels & Racor's FBO-10 & FBO-14 Housings. Performance is improved due to Teflon® coated screen separators and reliable radial sump seals.

DESCRIPTION Flow is from outside to inside through the cartridge. Coalesced water is repelled by the separator and drops to the sump for daily draining. Clean, dry fuel exits the cartridge through the nozzle at the top.

CARTRIDGE SELECTION TABLE

Replace the cartridge when the differential pressure exceeds 15 psi or after 1 year of service, whichever occurs first.

*Because of the limited sump space in these vessels, IT IS IMPERATIVE to drain the sump at EVERY FUELING. It is also important to recognize that these OS cartridges by themselves do not provide a water defense system. One water defense option is to use the Water Detection Probe, Velcon part number 125-Q.
