Genuine AirTAC filter regulator, order code GTFR20006LJNWK from the GTFR200 range. The options this code selects are decoded below; series data follow the official AirTAC catalog.
The GTFR20006LJNWK is the leanest low-pressure build of the AirTAC GT200-series filter regulator. The trailing option letters decode as follows: 06 selects the 1/8" PT port, L is the low-pressure type regulating 0.15 - 0.4 MPa (20 - 58 psi), N deletes the pressure gauge, J omits the mounting bracket, W fits the fine 5 um element instead of the standard 40 um, and K adds a built-in check valve. Like every GTFR200 it uses the short PC bowl with differential plus manual drain, the compact GT200 package derived from the GA200 for tight spaces.
Because this code strips out the gauge and the bracket and adds a check valve, it suits panels where an external gauge is already installed and where air must not flow back through the unit. The 5 um element delivers cleaner air downstream of the regulator, which protects fine valves and sensors from contamination.

Choose GTFR20006LJNWK when you want the 1/8" low-pressure unit without a local pressure display and without the bracket, but you do want the K check valve to hold downstream pressure. If you need to read the regulated pressure at the unit, step up to GTFR20006LJWK, which keeps the check valve and adds the gauge. If your line is 1/4" rather than 1/8", move to the 08 port versions such as GTFR20008LJWK.
The L version's 0.15 - 0.4 MPa (20 - 58 psi) window matches lab and test benches that run delicate components at pressures a standard regulator cannot reach accurately.
The W 5 um element supplies filtered air to pneumatic sensors and low-flow instrumentation on a 1/8" PT line, while the check valve prevents backflow disturbances.
With no bracket (J) and the short PC bowl of the GT200 family, this unit mounts inside existing enclosures where panel space and height are limited.
Port 1/8" PT thread (06), low-pressure type L regulating 0.15 - 0.4 MPa (20 - 58 psi), 5 um filter element (W), no gauge (N), no mounting bracket (J), built-in check valve (K), short PC bowl with differential plus manual drain, fluid air.
The N option deletes the pressure gauge and the J option deletes the mounting bracket, so confirm your panel has its own gauge and fixing method. Everything else stays as the sibling units: same short PC bowl, same 5 um element, same 0.15 - 0.4 MPa (20 - 58 psi) low-pressure range, plus the check valve that the base GTFR20006LJW does not carry.
