Genuine AirTAC filter regulator, order code GTFR20006LJNW from the GTFR200 range. The options this code selects are decoded below; series data follow the official AirTAC catalog.
The AirTAC GTFR20006LJNW is a GT200-series filter regulator whose W option replaces the standard 40 um element with a 5 um element, delivering noticeably cleaner air for sensitive downstream equipment. It is built on the 1/8 in (06) port with PT thread and the low-pressure L type, which regulates 0.15 - 0.4 MPa (20 - 58 psi) for circuits that never see full shop air pressure.
Like every GT200 unit it uses the short PC bowl, the compact short-bowl version of the GA200 body, with a differential plus manual drain. N deletes the gauge and J deletes the mounting bracket, so the code describes a bare, compact prep unit: fine filtration, low-pressure regulation and no accessories you did not ask for.

The W letter is the deciding difference here: GTFR20006LJN uses the standard 40 um element, while this code filters down to 5 um, the right choice when pilots, instruments or small actuators need cleaner air. If you also need downstream retention on supply loss, the ordering table lists K (check valve) as a separate letter that can be specified alongside; otherwise GTFR20006LJNK covers that need with the 40 um element.
Supplying 0.15 - 0.4 MPa (20 - 58 psi) air to pneumatic instruments and sensors from a 1/8 in PT line, where the 5 um element removes finer particles than the standard 40 um element would.
Protecting small pilots and compact actuators that run at low pressure, since the 5 um W element keeps contaminant out of narrow internal passages.
Feeding bench-scale rigs that need both gentle low-pressure regulation and clean air, with the bare no-gauge, no-bracket configuration letting the lab add its own pressure indication.
Port 1/8 in (06) with PT thread; low-pressure L regulation of 0.15 - 0.4 MPa (20 - 58 psi); 5 um filter element (W); short PC bowl with differential plus manual drain; no gauge (N), no bracket (J) and no check valve.
W swaps the standard 40 um element for a 5 um element, so the air delivered downstream is cleaner, which suits instruments and finely machined components. The pressure range stays at 0.15 - 0.4 MPa (20 - 58 psi) and the 1/8 in PT port, short PC bowl and drain arrangement are unchanged from the rest of the low-pressure 1/8 in family.
