The AirTAC GR20006LF2TK 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 GR20006LF2TK is a genuine AirTAC GR-series air pressure regulator: it does one job, holding downstream pressure steady, and it does nothing else - no filtration and no lubrication. This 200-size unit is decoded as the low-pressure type (L), so its adjustment range tops out at 0.4 MPa, and it carries a 1/8 in NPT port (T). The F2 code means a square pressure gauge with a psi scale is fitted, and the K code means a reverse/check valve is built in to hold downstream pressure if the supply drops. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -20 to 70 C, wider than the rest of the G family.
This is a genuine AirTAC part. The GR series spans 200, 300, 400 and 600 sizes with ports from 1/8 in to 1 in, in standard and low-pressure types, with gauge scale, thread (PT standard, G and NPT as options) and check-valve choices to order. Flow is published as curves rather than a single rated figure, so 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.
| GR200 | G-series pressure regulator, 200 body — sets the port range. |
|---|---|
| 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. |
| (blank) | Fixing bracket included. |
| (blank) | Pressure gauge fitted (blank). |
| 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.

Fixture clamps that must close gently rather than at full line pressure need a setpoint well below 1 MPa. This low-pressure GR regulator holds a steady clamp force at the fixture, and the check valve keeps the clamp from relaxing if the shop air dips.
Finishing lines run atomizing air at modest, closely held pressures for consistent droplet size. Set the GR20006LF2TK once at the booth drop and read the psi gauge directly, keeping each gun's supply stable across a shift.
Light-duty cylinders and air pilots on cartoning and labeling machines can be overpowered by full header pressure. A dedicated low-pressure regulator at each station lets technicians tune each circuit independently without touching the main line setting.
Pick the size by the flow your line needs: 200 is the compact step with a 1/8 in port here, and the larger 300/400/600 sizes carry bigger ports and more flow - we can confirm the flow curves against your demand before you order. Choose the low-pressure type (as decoded here) when your setpoint stays at or below 0.4 MPa; the standard type covers 0.05-0.9 MPa. Decide the gauge scale you want to read (MPa, psi or bar - this unit ships with a square psi gauge), the thread you need (PT is the standard; G and NPT are order options, and this unit is NPT), and whether a reverse/check valve is worth having to hold downstream pressure. A mounting bracket is included, and GR also panel-mounts.
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, not as a single rated number, so there is no one figure we can honestly quote. Tell us your line pressure, setpoint and the flow your application needs, and we will confirm the sizing against the datasheet curves on request before you order.
L marks the low-pressure regulator type: its adjustment range tops out at 0.4 MPa, which suits circuits that must never see full line pressure. If you need setpoints up to 0.9 MPa, choose the standard GR type instead. Maximum inlet pressure is 1.0 MPa (145 psi) either way.
