About the Airtac GTFR Filter Regulator GTFR20008LNWK
The GTFR20008LNWK is the no-gauge, check-valve build of the AirTAC GTFR200 low-pressure filter regulator. The 08 in the order code sets the 1/4 in PT port, and the L type regulates across 0.15 to 0.4 MPa (20 to 58 psi), a band the standard S units cannot reach. The W option fits a 5 um element instead of the standard 40 um cartridge, so downstream valves and actuators receive noticeably cleaner air.
Two options define this code. N deletes the pressure gauge from the body, so the output setting is verified on a separate panel gauge or fixed during commissioning. K builds a check valve into the flow path, which stops downstream pressure from bleeding back through the unit when the supply is interrupted. Condensate is shed through the differential plus manual drain under the short PC bowl, and the mounting bracket ships as standard because the code carries no J.

How to choose
Choose GTFR20008LNWK over GTFR20008LW when you do not want a gauge on the body; GTFR20008LW is the same low-pressure, 5 um regulator but gauged and without the check valve. If your line runs normal plant pressure rather than the 0.15 to 0.4 MPa band, move to the standard-pressure 08 codes and drop the L from the order. Port sizing matters too: the 06 variants reduce the ports to 1/8 in, while this code keeps 1/4 in flow through a PT-threaded body, with G or T available for G or NPT threads.
Applications
Low-pressure dispensing and coating lines
Regulate feed air to nozzles and metering valves inside the 0.15 to 0.4 MPa window, with the 5 um element protecting fine tips and the check valve holding line pressure through brief supply dips.
Delicate film and carton handling
Set gentle gripper and vacuum-assist pressures in the L band; with no body gauge the unit stays compact where a separate instrument already sits on the manifold.
Lab and pilot bench setups
PT 1/4 in plumbing, a space-saving short PC bowl and a manual drain suit short-run benches, and the included bracket fixes the unit to a frame without extra hardware.
FAQ
What are the key figures of the GTFR20008LNWK?
Port 1/4 in (08) with PT thread; low-pressure regulation 0.15 to 0.4 MPa (20 to 58 psi); 5 um filter element (W); short PC bowl with differential plus manual drain; mounting bracket included; no pressure gauge (N); check valve fitted (K).
Why order the K check valve on a filter regulator?
The check valve blocks reverse flow through the unit, so downstream pressure is held if the upstream supply drops or is shut off. The nearby sibling GTFR20008LW, identical apart from its fitted gauge, carries no check valve and lets downstream air back-feed through the body.
