AirTAC GR200-08 Pressure Regulator (GR20008LF2K)
The AirTAC AirTAC GR200-08 Pressure Regulator (GR20008LF2K) 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 PT1/4" 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.

About the AirTAC GR200-08 Pressure Regulator (GR20008LF2K)
GR20008LF2K is a genuine AirTAC GR-series air pressure regulator - regulation only, with no filter element and no lubricator in this unit. The size 200 body carries a 1/4 inch PT thread, is built as the low-pressure type (L) with adjustment up to 0.4 MPa, and has an embedded square gauge scaled in psi. The K suffix means a reverse/check valve is fitted, and the blank bracket position means the bracket is included. Medium is compressed air; operating temperature is -20 to 70 C.
This is a catalogue AirTAC part within the GR range, which also comes in sizes 300, 400 and 600, with G (BSPP) or NPT threads, other gauge scales and a no-gauge option. Flow for these regulators is published as curves rather than a single rating, so we will confirm flow and datasheet figures for your duty 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.
Model Code: AirTAC GR200-08 Pressure Regulator (GR20008LF2K)
| GR200 | G-series pressure regulator, 200 body — sets the port range. |
|---|---|
| 08 | Port size PT1/4". 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. |
| (blank) | PT 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.
Size Class
- GR200PT1/8" - PT1/4"
- GR300PT1/4" - PT1/2"
- GR400PT3/8" - PT1/2"
- GR600PT3/4" - PT1"
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.

Where the AirTAC GR200-08 Pressure Regulator (GR20008LF2K) Is Used
Wire and cable marking printers
Feed the inkjet or hot-stamp coding heads on an extrusion line with a low, closely held air setting, with the check valve helping isolate the printer circuit when the main supply is shut off.
Conveyor hold-down and diverting air
Regulate gentle hold-down or diverter air on a packaging conveyor, where a low setting below 0.4 MPa protects cartons and labels during product changeovers.
Panel-mounted sub-circuits on OEM machines
Give an OEM machine a dedicated, labelled low-pressure sub-circuit behind the control panel, with the psi-square gauge visible on the door and the check valve fitted as specified on the electrical-pneumatic drawing.
Is the AirTAC GR200-08 Pressure Regulator (GR20008LF2K) the Right Regulator?
Size the body to the line: 200/1/4 inch here, with GR300, GR400 and GR600 offering larger ports where the flow demand rises. This L version adjusts up to 0.4 MPa, making it the pick for low setpoints; standard GR units cover up to 0.9 MPa. Decide on the K option: here the reverse/check valve is fitted, useful where backflow into the circuit must be blocked. The square gauge reads psi (F2); MPa and bar scales are alternatives. Thread is PT as standard, with G and NPT as catalogue options. Flow is published only as curves - ask us to confirm sizing against your application before ordering.
Quick checklist
- ✓ Body size for your peak flow (PT1/4" here)
- ✓ Standard 0.9 MPa or low-pressure 0.4 MPa
- ✓ Gauge fitted, or order N without
- ✓ Gauge shape C round / F square
- ✓ Scale MPa (1), psi (2) or bar (3)
- ✓ Reflux valve needed, order K
Installation & Maintenance Notes
- check Install downstream of the filter, following the airflow arrow.
- check Keep inlet pressure at or below 1.0 MPa (145 psi).
- check Set pressure while air is flowing, then lock the knob.
- check Adjust within 0.05 - 0.4 MPa (7 - 58 psi) only.
- check Operating range -20 to +70 °C.
- check Panel-mount or use the fixing bracket; do not hang it on tubing.
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 GR200-08 Pressure Regulator (GR20008LF2K) FAQ
Yes. AirTAC publishes regulator flow as curves, not as a single rated number, so we do not state a figure on the product page. Share your inlet pressure, set pressure and consumption and we will confirm the flow data for the GR20008LF2K from the datasheet on request.
K means a reverse/check valve is fitted in this unit, whereas the same regulator without the K is supplied without it. The rest of the code decodes as before: size 200, 1/4 inch PT port, low-pressure type up to 0.4 MPa, and a square gauge reading in psi.
