AirTAC GR200-08 Pressure Regulator (GR20008LF1K)
The AirTAC AirTAC GR200-08 Pressure Regulator (GR20008LF1K) 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 (GR20008LF1K)
GR20008LF1K is a genuine AirTAC GR-series air pressure regulator: regulation only, with no filter bowl and no lubricator. This size 200 unit is plumbed with a 1/4 inch PT thread, is the low-pressure type (L) with an adjustment range up to 0.4 MPa, and carries an embedded square gauge reading in MPa. The trailing K in the code means a reverse/check valve is fitted, and the blank bracket position means the mounting bracket is included. Working medium is compressed air; operating temperature is -20 to 70 C.
This is a catalogue AirTAC part. The GR series is also offered in sizes 300, 400 and 600 with larger ports, alternative G (BSPP) and NPT threads, round external gauges and different pressure scales. Flow is published as curves rather than a single rating, so ask us to confirm flow and 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.
Model Code: AirTAC GR200-08 Pressure Regulator (GR20008LF1K)
| 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. |
| 1 | Gauge scale: MPa. 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

- 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 (GR20008LF1K) Is Used
Low-pressure gluing and coating heads
Set a gentle, steady supply pressure for glue pots, spray valves or coating heads on a packaging or converting line that operate below 0.4 MPa, with the MPa-scale square gauge at the panel for direct setting.
Bench fixture clamping circuits
Feed a pneumatic clamp or hold-down circuit on a machining or assembly fixture where a reduced setting and a check valve to hold the downstream side are wanted on a compact 1/4 inch drop.
Pilot air for process valve actuators
Supply low-pressure pilot air to diaphragm-actuated control valves on a water-treatment or chemical skid, keeping the pilot loop isolated from the higher main header pressure.
Is the AirTAC GR200-08 Pressure Regulator (GR20008LF1K) the Right Regulator?
Step up from size 200 (1/4 inch) to GR300, GR400 or GR600 when your line needs a larger port and more flow capacity; the port code (08 = 1/4 inch here) follows the size. This L version is the low-pressure type, adjustable up to 0.4 MPa - choose the standard GR if your setting point sits higher. Pick the gauge scale you want: this unit reads MPa (F1), with psi (F2) and bar (F3) variants available. The K option adds a reverse/check valve; thread choices are PT (standard on this code) with G and NPT as catalogue options. Note that flow is published as curves, not a single rating - 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 (GR20008LF1K) FAQ
AirTAC publishes regulator flow as curves rather than a single rated figure, so we do not quote one number here. Tell us your line pressure, set pressure and expected consumption, and we will confirm the flow figures from the datasheet for this exact model on request.
L marks the low-pressure type of the GR series, with an adjustment range up to 0.4 MPa instead of the standard regulator range. K means a reverse/check valve is fitted in this unit. Both are decodable order options, and the square gauge here reads in MPa.
