Genuine AirTAC filter regulator, order code GTFR20008LJNWK from the GTFR200 range. The options this code selects are decoded below; series data follow the official AirTAC catalog.
GTFR20008LJNWK is the fully optioned low-pressure build of the GTFR200 filter regulator: W gives the 5 um element instead of the standard 40 um cartridge, and K adds a check valve so downstream pressure survives an upstream supply loss. The L type regulates 0.15 to 0.4 MPa (20 to 58 psi) through a 1/4 in (08) PT port on the short PC bowl body.
The N and J positions are also active here, so this code arrives without a pressure gauge and without a mounting bracket. Drainage stays differential plus manual, emptying the bowl automatically in normal flow with a hand purge available when needed.

Among the no-gauge, no-bracket 1/4 in low-pressure codes, this one is the only combination of the 5 um element and the check valve. Pick GTFR20008LJNWK when your load needs both fine air and pressure retention, for example a circuit that must not vent if the feed drops. GTFR20008LJNW keeps the 5 um element but removes the check valve, and GTFR20008LJNK returns to the 40 um element while keeping the valve. Add a gauge or bracket by deleting the N or J position from the code.
Sealing or tuck stations at 0.15 to 0.4 MPa (20 to 58 psi) keep their set pressure through supply dips, thanks to the K check valve on the 1/4 in PT port.
Sorter and diverting actuators with tight valve clearances run on the 5 um W element, an upgrade over the standard 40 um cartridge in the same body.
The J no-bracket, N no-gauge build plus the short PC bowl makes this code easy to bury inside a control block, with manual drainage for service access.
Port: 1/4 in (08), PT thread. Type: low-pressure L, regulating 0.15 to 0.4 MPa (20 to 58 psi). Filter element: 5 um (W). Check valve: fitted (K). Gauge: none (N). Bracket: none (J). Bowl: short PC, differential plus manual drain. Fluid: air.
W replaces the standard 40 um element with a 5 um cartridge for cleaner air, and K adds a check valve that holds downstream pressure when the upstream supply is cut. GTFR20008LJNW has only W, and GTFR20008LJNK has only K with the 40 um element.
