The AirTAC GR20006LJF2TK AirTAC Low-Pressure Regulator, NPT1/8 is a genuine G-series air pressure regulator. It holds a stable downstream pressure over the range 0.05 - 0.4 MPa (7 - 58 psi) with PT1/8" ports, and ships with a pressure gauge. A regulator does not filter the air — put a GF filter upstream, or use a GFR filter regulator, when water and particulate must also be removed.
The AirTAC GR20006LJF2TK is a 200-size air pressure regulator that does one job only: holding downstream pressure steady. This is the low-pressure (L) version, so its adjustment range tops out at 0.4 MPa, and it is built for circuits that must never see full line pressure. The 06 port code gives a 1/8 in NPT thread, and the F2 code means an embedded square gauge on a psi scale is fitted so the setpoint can be read directly at the unit. The K code adds a reverse (check) valve, and the J code means no mounting bracket is supplied, though the GR body is also panel-mountable.
This is a genuine AirTAC part. The GR family runs from 200 up to 600 size with port options from 1/8 in to 1 in, thread options PT (standard), G (BSPP) and NPT, standard or low-pressure regulation, gauge choices and an optional check valve. Maximum inlet pressure is 1.0 MPa (145 psi) and the GR works from -20 to 70 C, wider than the rest of the G series. Flow is published as curves rather than a single rating, so ask us and we will confirm the datasheet figures for your application.

Specifications follow the official AirTAC G-series air-preparation data. Note the GR temperature range is -20 to +70 °C, wider than the other G-series units. A regulator has no bowl and no filter element, so there is no filtering grade. Flow curves, weight and outline dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.

|---|---|
| 06 | Port size PT1/8". This body offers 06 = PT1/8", 08 = PT1/4". |
| L | Low-pressure type — 0.05 - 0.4 MPa (7 - 58 psi). Blank is standard, L is the low-pressure type. |
| J | Supplied without bracket. |

| F | Gauge shape: Square. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| T | NPT thread. PT is the default; G is BSPP and T is NPT. |
| K | Reverse-flow (reflux) valve fitted. |
Field order is size, port, type, bracket, gauge, gauge shape, scale, thread, reflux — a blank position takes the default. Example: GR300-08LNK is a 300 body, PT1/4", low-pressure type, no gauge, with reflux valve.
A larger body carries a larger port and holds set pressure better as flow rises. AirTAC publishes flow only as curves, so size the body from your peak demand with headroom rather than from a single rated figure.

Valve pilots, pressure switches and sensor-actuated control circuits on a stamping or forming press need a steady, limited supply well below main line pressure. This low-pressure GR with a psi-scale gauge lets a technician set and read the pilot band at the manifold.
Lab benches feeding air-operated valves, sample pumps and small fixtures on analytical or materials-testing rigs need gentle, stable pressure that will not disturb the test. The 1/8 in NPT port suits compact bench plumbing, and the check valve keeps the setpoint if the shop supply dips.
A dispensing or small pick-and-place station on a carton-sealing line uses short actuator strokes that misfire if pressure creeps up. Setting this regulator at the station keeps the head consistent, and the embedded square gauge gives the operator a visible setpoint without tools.
Start with the port step: 200 size carries the smallest ports in the GR range, and this unit is 1/8 in NPT, so match it to lines sized for light duty. Then check the pressure band: this is the L low-pressure type with a range up to 0.4 MPa; if you need to regulate up to 0.9 MPa, order a standard GR instead. Choose the gauge scale you want (MPa, psi or bar) and whether the embedded square gauge or the optional external round gauge suits your panel. Thread is a real ordering decision: PT is the catalogue standard, while G (BSPP) and NPT are ordered as suffix codes, as on this T-coded unit. Bracket J means no bracket is fitted; leave the position blank if you want one. The K check valve here holds downstream pressure if upstream supply is lost.
One honest note on sizing: AirTAC publishes GR flow as curves, not as a single rated figure, so we cannot quote you a rated flow number. Send us your application details and we will confirm the datasheet curve against your demand before you order.
Quick checklist
The reflux valve lets air flow back through the regulator, which is useful when downstream volume must vent quickly. A regulator does not remove water or particulate; that is the filter's job.
AirTAC publishes GR regulator flow as performance curves, not as a single rated number, so we do not quote a rated flow, Cv or SCFM figure for this unit. Tell us your inlet pressure, set pressure and air demand, and we will confirm the datasheet curve for the 200 size against your application before you order.
L marks the low-pressure regulator type: its adjustment range tops out at 0.4 MPa instead of the standard GR range. The F2 code means an embedded square gauge is fitted on a psi scale, so the downstream setpoint is read directly in psi. Maximum inlet pressure is still 1.0 MPa (145 psi), and the unit works from -20 to 70 C.
