The AirTAC GR20006LJF1TK 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 GR20006LJF1TK is a genuine AirTAC GR200 low-pressure air pressure regulator for compressed air, with a 1/8 in NPT port. This is the low-pressure (L) type, so the outlet pressure is set anywhere from near zero up to 0.4 MPa, which suits circuits that must never see full line pressure. Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the operating temperature range is -20 to 70 C, wider than the rest of the G series. The embedded square gauge with MPa scale is fitted, a reverse/check valve (K) is included to hold the downstream setting if the upstream supply drops, and the J suffix means no mounting bracket is supplied - the GR body is also panel-mountable.
This is a genuine AirTAC part from the GR regulator family, which covers sizes 200, 300, 400 and 600 with progressively larger ports and flow capacity, plus options for thread type (PT standard, G or NPT), gauge scale (MPa, psi or bar), bracket and reverse valve. We do not quote a single rated flow figure because AirTAC publishes flow as curves rather than a rating - ask us and we will confirm the datasheet figures for your application on request.

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. |
| 1 | Gauge scale: MPa. 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.

On a water-treatment or chemical plant manifold, positioners and pilot stages of large diaphragm valves often need a low, stable supply well below line pressure. This low-pressure regulator sets the pilot circuit anywhere up to 0.4 MPa, and the reverse/check valve holds that setting if the header pressure dips.
Gentle hold-down clamps and pushers on a carton or blister packaging line can crush product if fed at full line pressure. A GR200 low-pressure regulator at the 1/8 in take-off limits the clamp circuit to a safe setting, with the fitted square gauge letting operators verify the value at a glance.
Test benches, sample-preparation stations and lab air rings frequently run instruments and air curtains at low pressure from a shop-air drop. This compact 1/8 in NPT regulator steps the bench supply down to the required low setting, and its -20 to 70 C range covers unheated back-of-house service air.
Start with the port and size step: this unit is GR200 with a 1/8 in NPT port, the smallest step in the range; step up to GR300/400/600 if the line demands more flow capacity. Because this is the L (low-pressure) type, choose it when the downstream setting must stay at or below 0.4 MPa; the standard GR type covers settings up to 0.9 MPa. The fitted square gauge reads in MPa - psi or bar scales can be ordered instead. Thread is NPT here; PT is the AirTAC standard and G (BSPP) is also a catalogue option. The J code means no bracket is included, and the K code means a reverse/check valve is fitted. Flow is published as curves, not a single rating, so ask us to confirm sizing against your application before ordering.
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 regulator flow as curves rather than a single rated figure, so we do not quote a l/min, SCFM or Cv number. Tell us your line size and the flow your application needs, and we will confirm the datasheet curve figures for the GR200 at your setting on request before you order.
The L in the code makes this the low-pressure GR type: the outlet can be set anywhere up to 0.4 MPa, whereas the standard GR type adjusts up to 0.9 MPa - choose L only when your circuit must stay at or below 0.4 MPa. The K means a reverse/check valve is fitted, and the J means no mounting bracket is included (the body is still panel-mountable).
