About the Airtac GTFR Filter Regulator GTFR20008SJNK
The GTFR20008SJNK takes the AirTAC GT200 filter regulator in the 1/4 in (08) size and adds the K option: a built-in check valve. The K suffix is what separates this code from GTFR20008SJN, which flows only in one direction of supply logic but holds no residual pressure when the line is shut. Filtration stays at the standard 40 um element and the drain is differential plus manual on the short PC bowl.
Both ports are 1/4 in with PT thread, the standard for this body. As with all J/N builds, no pressure gauge is fitted and no mounting bracket is supplied, so plan your own fixing and pressure indication.

How to choose
Choose GTFR20008SJNK over GTFR20008SJN when backflow or hold-up matters, for example keeping a charged circuit downstream while the upstream side vents; the K option is the only difference between the two codes. Compared with GTFR20008S (gauge and bracket included, no check valve), this build suits compact installs that carry their own gauge and bracket. For 5 um cleanliness instead of check-valve function, pick GTFR20008SJNW.
Applications
Circuit hold-up on shutdown
The K-option check valve helps retain downstream pressure when the upstream 1/4 in PT supply is isolated, protecting cylinders and actuators mid-cycle.
Clamping station feed
Conditions air to 40 um at a clamping station on 1/4 in lines where a sudden supply loss must not instantly vent the clamped side.
Compact retrofit swap
No gauge or bracket to accommodate, so the short PC bowl body with built-in check valve replaces older combined units in tight machine frames.
FAQ
What are the key figures of the GTFR20008SJNK?
Port: 1/4 in (08), PT thread standard. Type: S, standard pressure. Gauge: none (N), bracket: none (J). Element: 40 um standard. Check valve: included (K). Bowl: short PC with differential plus manual drain. Fluid: air.
What does the K option add compared to GTFR20008SJN?
The K suffix fits a check valve inside the same GT200 body. Everything else is identical: 1/4 in PT ports, 40 um element, no gauge, no bracket. The valve gives one-way flow behavior so downstream pressure is not lost straight back through the unit when supply drops.
