About the Airtac GTFR Filter Regulator GTFR20006LJK
GTFR20006LJK combines three decoded options on the AirTAC GTFR200 body: L for the low-pressure regulated range of 0.15 to 0.4 MPa (20 to 58 psi), J for no mounting bracket, and K for an integrated check valve. The 06 body has a 1/8 in PT port, the fitted gauge reads MPa and psi, and the standard 40 um element feeds a short PC bowl drained by differential plus manual action.
The K option is what separates this code from its siblings: the check valve lets downstream air hold its regulated pressure when the upstream supply is removed, instead of dumping back through the regulator. That matters on circuits where a fixture, clamp or gauge reading must survive brief air-off periods, while the bracketless J build suits panel or manifold fixing.

How to choose
Pick GTFR20006LJK when you want low-pressure regulation on a 1/8 in line plus the pressure-holding behaviour of the check valve. Without the valve, the matching code is GTFR20006LJ; with the bracket added, it is GTFR20006LK with K and standard bracket. If your supply is 1/4 in rather than 1/8 in, move to the 08 body, and if finer filtration is needed for sensitive components, add W for the 5 um element. The S type replaces L when standard pressure regulation is acceptable.
Applications
Low-pressure clamping fixtures
Delicate parts held by low-pressure clamps keep their set force during brief supply losses, because the K check valve retains the downstream pressure between 0.15 and 0.4 MPa (20 to 58 psi).
Instrument air with stable readings
Air-operated gauges and transducers keep their calibrated pressure when upstream air is switched off, protected by the 40 um element and fed through a 1/8 in PT connection.
Pilot circuits on multi-valve machines
A pilot supply section mounted directly on the manifold without a bracket stays pressurised while other sections are de-energised, avoiding re-adjustment after every cycle stop.
FAQ
What are the key figures of the GTFR20006LJK?
Port: 1/8 in (06), PT thread standard. Type: low-pressure L, regulated range 0.15 to 0.4 MPa (20 to 58 psi). Check valve: included (K). Element: 40 um standard. Bowl: short PC with differential plus manual drain. Gauge: included. Bracket: not included (J code). Fluid: air.
Why order the K option on this low-pressure unit?
K adds a check valve to the GTFR20006LJ configuration. With upstream air removed, the valve prevents downstream air from flowing back through the regulator, so the circuit keeps its set pressure in the 0.15 to 0.4 MPa (20 to 58 psi) range. If you do not need this behaviour, order GTFR20006LJ instead.
