Genuine AirTAC filter regulator, order code GTFR20006SWK from the GTFR200 range. The options this code selects are decoded below; series data follow the official AirTAC catalog.
The AirTAC GTFR20006SWK combines three options on one 1/8 inch (06) port unit: W for the 5 um fine element instead of the standard 40 um, K for a built-in check valve, and the standard type (S) with a fitted pressure gauge. The check valve keeps the downstream side backed up when upstream supply is lost, which matters on circuits that must hold their set condition.
The body is the GT200 short PC bowl version, the compact layout that retains GA200 features for tight mounting spaces, with a differential plus manual drain for condensate. A mounting bracket is included (no J in the code) and threads are PT as standard because no G or T is selected.

Choose this code when your 1/8 inch line needs fine 5 um filtration and check-valve function together: against GTFR20006SW it is identical except for the added K option, and against GTFR20006SWK with a different thread letter it keeps PT as the standard connection. If the line is 1/4 inch move to the 08 codes, and if the circuit runs in the low-pressure band the L codes with their 0.15 to 0.4 MPa (20 to 58 psi) range are the correct pick. Dropping K (or W) from the code removes that option, not a feature of the base unit.
On a clamping or holding line fed by 1/8 inch tubing, the K check valve limits backflow on supply loss while the 5 um element protects the downstream components from fine contamination.
Feeding compact pilot valves through this unit, operators read the regulated pressure on the fitted gauge, the W element delivers cleaner air than the standard 40 um, and the manual-plus-differential drain clears the short PC bowl.
The GT200 short-bowl design packs the filter regulator function into a smaller body than GA200, and with the included bracket this PT-threaded 1/8 inch unit mounts where space is scarce.
Port 1/8 inch (06), PT thread standard, standard type (S) with pressure gauge, 5 um element (W), check valve (K), short PC bowl with differential plus manual drain, and mounting bracket included. The pressure range is the standard-type range; for 0.15 to 0.4 MPa (20 to 58 psi) select the L version instead.
K adds a check valve to an otherwise identical 1/8 inch, 5 um, standard-type unit with gauge and bracket. Everything else in the code stays the same: same short PC bowl, same drain type, same PT thread. For G or NPT threads order the G or T variants of the same code.
