About the Airtac GTFR Filter Regulator GTFR20008LJNW
GTFR20008LJNW pairs the GT200 short-bowl filter regulator with the W option: a 5 um element that polishes air down to a finer grade than the standard 40 um cartridge. The L type regulates 0.15 to 0.4 MPa (20 to 58 psi), so it suits circuits that cannot tolerate ordinary supply pressure, and the 08 port takes a 1/4 in PT connection.
This build carries N and J, so it ships without a pressure gauge and without a mounting bracket, and it has no check valve, meaning downstream pressure is not held if the upstream line is shut off. The short PC bowl drains differentially during flow and can also be emptied manually.

How to choose
This is the fine-filtration, minimal-hardware choice in the 1/4 in low-pressure family. If your circuit also needs downstream pressure retention, step up to GTFR20008LJNWK, which adds the check valve to the same 5 um element. If the standard 40 um element is clean enough, GTFR20008LJNK gives you that element plus the check valve, or GTFR20008LJN stays with 40 um and no valve. Dropping the N adds a gauge, and dropping the J adds the bracket.
Applications
Fine-filtration instrument air
Test rigs and pilot devices on 1/4 in PT lines benefit from the 5 um element, protecting small orifices that a 40 um standard element would leave exposed.
Gentle low-pressure handling
Soft grippers and delicate product guides run inside the 0.15 to 0.4 MPa (20 to 58 psi) L band, where the finer element keeps valve seats clean.
Retrofit points with existing brackets
Because the J option omits the bracket, the bare short PC body drops onto machine frames or manifold plates that already carry their own mounting.
FAQ
What are the key figures of the GTFR20008LJNW?
Port: 1/4 in (08), PT thread. Type: low-pressure L, regulating 0.15 to 0.4 MPa (20 to 58 psi). Filter element: 5 um (W). Gauge: none (N). Bracket: none (J). Check valve: not fitted. Bowl: short PC, differential plus manual drain. Fluid: air.
What does the W option change?
In the GTFR200 ordering code a blank element position means the standard 40 um cartridge, while W substitutes a 5 um element for cleaner air downstream, the difference between this code and the 40 um GTFR20008LJNK or GTFR20008LJN builds.
