Canister Separator SI Series

Fully Qualified to EI 1581 5th Edition, Category M

Separator SI-xxx Series - Data Sheet #1943

DESCRIPTION


The SI-xxxx Series separator canister is composed of an inner Teflon®-coated 200 mesh screen. The open endcap on the five inch canister has a locking bayonet mount with wavy spring. The blind end has a nozzle for a DOD coalescer o-ring endcap.

These separators are qualified to Category M and M100 of the EI 1581 5th Edition Specification.

 

APPLICATION


The SI-xxxx Series separator canisters are made to fit over first stage coalescers in DOD military vessels such as those originally made to the MIL-F-27629, MIL-F- 27630, and MIL-PRF-52308 specifications.

The inner Teflon coating repels water droplets as fuel exits the canisters, adding another layer of protection to the fueling system. The water droplets in the annular gap between the outside diameter of the coalescer and the inside diameter of the separator canister fall to the sump area at the bottom of the filter vessel, where they can then be drained.
