Genuine AirTAC filter regulator, order code GTFR20006LK from the GTFR200 range. The options this code selects are decoded below; series data follow the official AirTAC catalog.
In the AirTAC GT200 series, the GTFR20006LK is the low-pressure filter regulator built on the compact short-bowl body: GT200 is the shortened version of GA200, so you keep the GA200 features where panel depth is tight. It regulates 0.15 - 0.4 MPa (20 - 58 psi) on 1/8 inch (06) PT ports and carries the standard 40 um filter element.
The K suffix adds a check valve, and unlike the N-coded units this build has a pressure gauge fitted, so the regulated downstream setpoint is readable directly on the unit within the low band it works in. The PC bowl is drained by differential plus manual operation, and a mounting bracket is included because the order code does not carry J.

Choose GTFR20006LK over GTFR20006L when the downstream line must include a check valve, and over GTFR20006LN when you want the gauge mounted on the unit. If your air line is 1/4 inch, step up to GTFR20008LK; for set pressures above this L version's 0.4 MPa ceiling, the standard type GTFR20006SK is the sibling to order.
Coating and dosing panels that work in the 0.15 - 0.4 MPa (20 - 58 psi) band, where the fitted gauge lets an operator read and verify the setpoint at the regulator itself.
Supplying a branch circuit whose layout calls for a check valve in line, matched here by the K suffix on a 1/8 inch (06) PT port connection.
Packaging and assembly machines with tight enclosures, where the GT200 short PC bowl format derived from GA200 and the included bracket keep the installed footprint small.
Port 1/8 inch (06) with PT thread, low-pressure regulation of 0.15 - 0.4 MPa (20 - 58 psi), 40 um filter element, short PC bowl with differential plus manual drain, pressure gauge fitted, check valve (K) and mounting bracket included. Fluid is air.
K adds a check valve; GTFR20006L is the same low-pressure, gauged unit without it. Both share the 1/8 inch PT ports, the 40 um element and the included bracket, so the ordering-code suffix is the only difference between the two builds.
