AirTAC GR200-08 Pressure Regulator (GR20008LF1)
The AirTAC AirTAC GR200-08 Pressure Regulator (GR20008LF1) 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 (GR20008LF1)
The AirTAC GR20008LF1 is a compressed-air pressure regulator from the G series, sized 200 with 1/4 in. PT ports. It is the low-pressure (L) type, so its output is adjustable up to 0.4 MPa for circuits that must not run at full line pressure. It carries a square embedded pressure gauge on an MPa scale, includes a mounting bracket, and is rated to 1.0 MPa (145 psi) maximum inlet pressure with an operating temperature of -20 to 70 C.
This is a genuine AirTAC part. The GR series is offered in sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 in., a choice of gauge (round or square; MPa, psi or bar scale), a low-pressure option, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so we confirm 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.
Model Code: AirTAC GR200-08 Pressure Regulator (GR20008LF1)
| 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. |
| (blank) | No reverse-flow valve (the default). |
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

- 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 (GR20008LF1) Is Used
Textile machine air-jet supply
Regulate the low-pressure air feed to pnuematic guides and thread tensioners on a textile machine, with the MPa gauge matching the machine's pressure schedule.
Electronics assembly pick-and-place
Supply gently regulated air to vacuum generators and small gripper cylinders on an electronics assembly module where low set points protect delicate parts.
Fume-cabinet and enclosure purging
Feed low-pressure purge air to instrument enclosures and ventilation-assist manifolds in a process plant, held well below the main header pressure.
Is the AirTAC GR200-08 Pressure Regulator (GR20008LF1) the Right Regulator?
This code fixes the key choices: size 200 with 1/4 in. PT ports, low-pressure (L) type with adjustment up to 0.4 MPa, and a square embedded gauge on an MPa scale. If your line needs higher set points, the standard GR type adjusts 0.05-0.9 MPa; if you prefer psi or bar readout or a round external gauge, those are separate order codes. PT thread is the standard; G (BSPP) and NPT are catalogue options, and a no-bracket (J) version exists.
For sizing, work from the port step: 200/1/4 in. suits light branch lines, while larger sizes carry more flow. Flow for this series is published as curves, not a single rated figure, so 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.
Without a reflux valve, air cannot flow back through the regulator — order the K option if reverse flow is required. A regulator does not remove water or particulate; that is the filter's job.
AirTAC GR200-08 Pressure Regulator (GR20008LF1) FAQ
AirTAC publishes GR series flow as curves rather than a single rated number, so there is no one figure we can quote. Tell us your inlet pressure and required downstream flow and we will confirm the sizing from the datasheet curves on request.
L is the low-pressure type, which limits the regulated output to up to 0.4 MPa instead of the standard 0.05-0.9 MPa range. F1 specifies the square embedded pressure gauge on an MPa scale; round gauges and psi or bar scales are separate order codes.
