The AirTAC GR20008LF2GK AirTAC Low-Pressure Regulator G1/4 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.
The GR20008LF2GK is an AirTAC GR-series pressure regulator: it does one job, holding downstream air pressure steady, and it carries no filter, bowl or lubricator. This unit is the GR200 size with a G1/4 (1/4 in) female port, built as the low-pressure type so its setpoint range tops out at 0.4 MPa. It comes with the embedded square pressure gauge on the psi scale, a reverse/check valve already fitted to hold downstream pressure when the supply drops, and a mounting bracket included; GR bodies are also panel-mountable.
This is a genuine AirTAC part. The GR family runs from GR200 through GR600, so you can step up in port size and flow capacity within the same control logic, and choose thread, gauge scale, check valve and bracket options to suit. Max 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. Rated flow is published as curves rather than a single figure, so ask us to confirm sizing against your application before ordering.

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.

| F | Gauge shape: Square. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |

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.

Holds a gentle, stable setpoint below 0.4 MPa on the clamp cylinders of a carton-sealing machine, so delicate packs are gripped without crushing.
Feeds a controlled low-pressure pilot signal to pneumatic valve actuators on a water-treatment skid, with the check valve holding the pilot line if supply dips.
Supplies steady low-pressure air to benchtop test rigs and pneumatic lab fixtures, with the psi-scale gauge letting operators read setpoints directly.
Start with the port and size: the GR200 with its 1/4 in connection suits lighter branch lines, and stepping to GR300/GR400/GR600 buys larger ports and more flow, so match the size to the air demand of the circuit rather than the pipe alone. This code is the low-pressure type (L), correct where the setpoint must stay at or below 0.4 MPa; the standard GR covers higher setpoints. The square gauge here reads in psi; MPa and bar scales are alternative order options. Thread is G (BSPP) on this unit, with PT as the catalogue standard and NPT available to order. A bracket is included and the body is panel-mountable. Because flow data is published as curves and not a single rating, send us your application details and we will confirm the right size before you order.
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 GR flow as performance curves rather than a single rated figure, so we do not quote a number here. Tell us your line pressure, setpoint and air demand, and we will confirm the flow data from the datasheet for this exact model before you order.
The L in the code marks the low-pressure version of the GR series: its adjustment range tops out at 0.4 MPa instead of the standard regulator's higher range. Choose it where the process needs fine, stable control at lower pressures; inlet pressure is still up to 1.0 MPa (145 psi), and temperature range is -20 to 70 C.
