About the Airtac GTFR Filter Regulator GTFR20008LJK
The K suffix is what separates GTFR20008LJK from its siblings: a check valve is built into this low-pressure filter regulator, in addition to the fitted gauge that reads MPa and psi. Air still passes 0.15 to 0.4 MPa (20 to 58 psi) regulation on the 1/4 inch (08) PT port with the standard 40 um element.
Like every GT200 unit it carries the short PC bowl with differential plus manual drain, and the J option means no mounting bracket is supplied. Confirm from the datasheet how the check valve behaves in your circuit before relying on it to hold downstream pressure.

How to choose
Order GTFR20008LJ instead if backflow protection is not a concern, or GTFR20008LJN if you do not want the gauge. The bracketless J configuration stays the same in both, and moving to standard pressure or a 5 um element would take you to the S or W suffix.
Applications
Hold settings through air-off events
Circuits where the upstream supply can be cut benefit from the built-in check valve, helping the low-pressure 0.15 to 0.4 MPa (20 to 58 psi) setting persist downstream.
Packaging machine clamp circuits
Clamp and hold stations on packaging lines use the 1/4 inch PT port, the MPa and psi gauge, and the check valve so a supply drop does not immediately vent the circuit.
Compact retrofit panels
The short PC bowl suits tight panels, and the J code skips the bracket where the frame already supports the unit, while the manual plus differential drain stays reachable.
FAQ
What are the key figures of GTFR20008LJK?
Port: 1/4 inch (08), PT thread. Type: low-pressure L at 0.15 to 0.4 MPa (20 to 58 psi). Gauge: fitted, MPa and psi. Element: 40 um. Check valve: included (K). Bracket: none (J). Bowl: short PC with differential plus manual drain.
What does each suffix on GTFR20008LJK stand for?
08 is the 1/4 inch port, L the low-pressure type, J the omission of the mounting bracket, and K the check valve. The blank positions of the code mean PT thread and the standard 40 um element were kept.
