The AirTAC GR20006LC3TK 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 GR20006LC3TK is an AirTAC GR-series air pressure regulator: it does one job, holding your downstream pressure steady at the setpoint you dial in. This is the 200 size with a 1/8 in NPT port, built as the low-pressure type with a regulation range of up to 0.4 MPa, so it suits circuits that must never see full line pressure. It carries a round pressure gauge reading in bar, a reverse (check) valve that lets downstream pressure hold when the upstream supply drops, and a mounting bracket is included; the GR body is also panel-mountable.
This is a genuine AirTAC part. The GR family spans the 200, 300, 400 and 600 sizes with port options from 1/8 in up to 1 in, standard or low-pressure regulation, gauge or no-gauge versions, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so send us your application and we will confirm the sizing and datasheet figures on request before you order.

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. |

| C | Gauge shape: Round. C is round, F is square. |
| 3 | Gauge scale: bar. 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 chemical or water-treatment skid, small pneumatic valve positioners and pilot actuators often need a gentle, stable supply well below plant line pressure. This low-pressure GR with a bar-scale gauge lets the technician set and read the pilot pressure directly at the valve assembly.
On an R&D or QC test bench running pneumatic fixtures and instruments, the 1/8 in NPT port suits compact drop lines, and the 0.4 MPa low-pressure range protects sensitive components. The check valve keeps the circuit held if the bench supply is momentarily interrupted.
On a cartoning or labelling machine, individual air sub-circuits - grippers, hold-downs, sensor blow-offs - each need their own trimmed pressure. A compact GR200 regulator per sub-circuit, panel-mounted on the included bracket, gives each function its own stable setting.
Start with the port step: the 200 size at 1/8 in is the smallest GR frame, so match it to the line size and the flow your circuit needs - for larger demand, step up to GR300, GR400 or GR600. This unit is the L (low-pressure) type, limited to 0.4 MPa; if your setpoint sits above that, choose the standard GR instead. The C in the code means a round gauge with a bar scale is fitted; square-gauge and MPa/psi scale options exist in the family if you prefer a different readout. The T gives an NPT thread - PT is the standard thread and G (BSPP) is also a catalogue option to order. The K adds a reverse/check valve, useful where a held downstream pressure matters, and the bracket is included.
One honest note on sizing: AirTAC publishes GR flow as curves, not as a single rated number, so we do not quote a flow figure here. Ask us to confirm the curve and 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.
We do not quote a single rated flow figure, because AirTAC publishes GR-series flow as performance curves rather than one number. Tell us your line size and demand and we will confirm the curve and correct sizing from the datasheet on request - that way you order the right size the first time.
The L in GR20006LC3TK marks the low-pressure type, whose regulation range tops out at 0.4 MPa - ideal for circuits that must never receive full line pressure (max inlet is still 1.0 MPa / 145 psi). The K means a reverse (check) valve is fitted, so downstream pressure is held if the upstream supply drops. If you need setpoints above 0.4 MPa, choose the standard GR type instead.
