About the Airtac GTFR Filter Regulator GTFR20008SJNWK
GTFR20008SJNWK is built for machines that already have their own pressure readout: the N option removes the pressure gauge, J removes the mounting bracket, and the letters end with K, which adds a check valve on the 1/4" (08) PT-threaded port. Filtration is the fine 5 um element (W) instead of the standard 40 um, so the air reaching sensitive valves and actuators is cleaner than the GT200 default.
The unit belongs to the short-bowl GT200 series, so it fits where the full-size GA200 will not, and the short PC bowl drains through a differential plus manual arrangement rather than an automatic drain. Pressure regulation is the standard type; if your line runs lower, the L version of the same size regulates 0.15 - 0.4 MPa (20 - 58 psi).

How to choose
Pick GTFR20008SJNWK when your control panel already displays downstream pressure, so a gauge here would be redundant - if you do want a gauge on the unit, order GTFR20008SJWK (same no-bracket, 5 um, check-valve build with gauge fitted). If the 5 um element is finer than your circuit needs, GTFR20008SJNK gives the same no-gauge, no-bracket, check-valve layout with the standard 40 um element. For 0.15 - 0.4 MPa (20 - 58 psi) circuits choose the L variant, and for NPT or G piping order the T or G thread versions of this code.
Applications
Instrument air without panel clutter
Feed 5 um-filtered air to flow switches, counters and other panel-mounted instruments that sit next to their own gauges, so the N no-gauge option keeps the unit compact behind the door.
Clamp circuits that must not backflow
The K check valve blocks air from returning through the regulator if upstream supply drops, helping a 1/4" PT-threaded clamping circuit hold its set pressure instead of bleeding back to the bowl.
OEM builds with custom subplates
With J deleting the bracket, machine builders manifold the unit straight onto their own plate or bracket design rather than working around the AirTAC-supplied one.
FAQ
What exactly does GTFR20008SJNWK give me?
A GT200-series filter regulator with a 1/4" (08) port, PT thread, standard pressure type, 5 um filter element, no pressure gauge (N), no mounting bracket (J), and a check valve (K). The bowl is a short PC bowl with differential plus manual drain.
Can I set the pressure accurately without the gauge?
Yes, but you need a separate readout: N removes the pressure gauge from this code, so set or monitor pressure with your panel instrument. If you want the setting visible on the unit itself, order the gauge-fitted sibling GTFR20008SJWK instead.
