About the Airtac GTFR Filter Regulator GTFR20008LJNK
The GTFR20008LJNK is a GT200-series filter regulator built for low-pressure circuits. Its L type regulates 0.15 to 0.4 MPa (20 to 58 psi), well below the standard setting band, and it mounts a 1/4 in (08) PT-threaded port on the short PC body that keeps the GA200 feature set in a smaller footprint. The N in the code means no pressure gauge is fitted, and J means no mounting bracket, so plan your panel space and pressure readout before ordering.
The trailing K adds a check valve, which holds downstream pressure if the upstream supply is interrupted, and the element stays the standard 40 um grade rather than the 5 um W option. Drain is differential plus manual, so the short PC bowl empties itself during normal flow and can be purged by hand.

How to choose
Choose this code when your line runs 1/4 in PT, your working pressure sits inside 0.15 to 0.4 MPa (20 to 58 psi), and you want the check valve function. If you need finer 5 um filtration instead of the standard 40 um element, order GTFR20008LJNWK, which combines W with K. If you can rely on a simple bowl drain without backflow hold-up, GTFR20008LJNW drops the check valve. Codes without N add a pressure gauge, and codes without J include the mounting bracket.
Applications
Low-pressure clamping and pressing
Fixtures that must not exceed a 0.15 to 0.4 MPa (20 to 58 psi) setpoint get the L-type band, while the check valve holds the clamp if the plant supply dips.
Pneumatic signal and sensing circuits
Pilot and sensor loops fed at 1/4 in PT stay stable on the standard 40 um element, with the N no-gauge build monitored by the panel's own instruments.
Compact machine-integrated supply points
The short-bowl GTFR200 body plus the J no-bracket build saves mounting space inside machine frames, and differential plus manual drainage suits enclosed cells.
FAQ
What are the key figures of the GTFR20008LJNK?
Port: 1/4 in (08), PT thread. Type: low-pressure L, regulating 0.15 to 0.4 MPa (20 to 58 psi). Gauge: none (N). Bracket: none (J). Filter element: standard 40 um. Bowl: short PC, differential plus manual drain. Extras: check valve (K). Fluid: air.
Why pick this code over GTFR20008LJNW?
Both share the same low-pressure band, 1/4 in PT port and no-gauge, no-bracket build, but GTFR20008LJNK keeps the standard 40 um element and adds a check valve to hold downstream pressure, while GTFR20008LJNW swaps to the 5 um element and omits the check valve.
