About the Airtac GTFR Filter Regulator GTFR20008SK
The GTFR20008SK is the 1/4 inch (code 08) port version of the AirTAC GTFR200 filter regulator from the GT200 series, ordered in standard (S) pressure type with a pressure gauge fitted. Its check valve (option K) lets downstream air hold its setting while the upstream side is vented or depressurized, and the integrated 40 um element removes particulates in one compact stage. The body uses PT thread as standard and comes with a mounting bracket already in the code.
Like every GTFR200, this unit carries a short PC bowl with differential plus manual drain, the compact GT200-format bowl that keeps the GA200 feature set in a smaller footprint for tight panels. If you want cleaner downstream air, the sibling GTFR20008SW swaps in a 5 um element instead of this standard 40 um one.

How to choose
Choose GTFR20008SK over GTFR20008SN or GTFR20008SNK if you want the factory-fitted pressure gauge for direct dial reading; the N codes ship without gauge. Against gauge-fitted GTFR20008S without K, this code adds the check valve for holding downstream pressure. If your line is 1/8 inch instead of 1/4 inch, step down to the 06 body (GTFR20006SK); for regulated pressures down to 0.15 - 0.4 MPa (20 - 58 psi), the L-type GTFR20008LK is the low-pressure alternative.
Applications
Circuit venting with pressure hold
The K check valve retains downstream pressure when the supply side is shut off or exhausted, so a 1/4 inch PT-threaded circuit keeps its regulated setting between shifts.
Machine air supply with local reading
With the fitted gauge, operators can read the regulated output directly at the 1/4 inch inlet station and drain the short PC bowl manually when the differential drain signals it.
Compact FRL corner on production equipment
The GT200 short PC bowl format keeps the filter regulator footprint small on machines where a full-depth GA200 body would not fit behind the panel.
FAQ
What are the key figures of the GTFR20008SK?
Port: 1/4 inch (ordering code 08). Pressure type: standard (S) with a fitted pressure gauge. Configuration: 40 um filter element, PT thread, mounting bracket included, and check valve (K) fitted. Bowl: short PC bowl with differential + manual drain. Fluid: air. The L-type sibling regulates 0.15 - 0.4 MPa (20 - 58 psi); confirm the standard-type regulated range from the datasheet.
How does the check valve in this code change daily operation?
The K option in GTFR20008SK means air flows normally from inlet to outlet but is prevented from flowing back out through the unit, so downstream pressure is retained if upstream supply is interrupted. Note that a check valve also means downstream air cannot be vented backwards through this unit, so plan venting accordingly. The bracket is included, and the gauge ships fitted since this is not an N code.
