The AirTAC GR30015LC2 AirTAC Pressure Regulator PT1/2 Low-Pressure 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 PT1/2" 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 GR30015LC2 is an AirTAC GR-series air pressure regulator: it does one job, holding downstream pressure steady from a compressed-air supply. This is the low-pressure (L) type, so its adjustment range tops out at 0.4 MPa instead of the standard regulator range - the right choice for circuits that must never see full line pressure. It is built in the 300 size with PT1/2 (1/2 in) ports, PT thread as standard, and it comes with an external round gauge scaled in psi so operators can read and set the outlet pressure directly. A mounting bracket is included, and the body is also panel-mountable.
This is a genuine AirTAC part. The GR family spans the 200, 300, 400 and 600 sizes with port options from 1/8 in to 1 in, gauge scales in MPa, psi or bar, an optional reverse/check valve, and G or NPT thread variants to order. GR handles a maximum inlet pressure of 1.0 MPa (145 psi) and works from -20 to 70 C - a wider temperature window than the rest of the G family. Flow is published as curves rather than a single rating, so ask us and we will confirm the datasheet figures against your application.

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.

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.

Set a gentle, stable feed pressure to paint guns and air-assisted applicators on a finishing line, where the low-pressure adjustment ceiling keeps atomising air safely below the 0.4 MPa limit.
Hold a steady, moderate pressure to looms, blowing nozzles and thread-guiding jets in a weaving shed, where the psi-scaled round gauge lets operators check the setting at a glance.
Regulate the air to pneumatic clamps and hold-downs on a cartoning or wrapping machine, with the included bracket mounting the regulator at the machine frame for easy adjustment.
Pick the GR size by the flow your line needs: the 300 size with its PT1/2 port sits in the middle of the 200/300/400/600 range, and the next size up buys more port and more flow. Because this is the L (low-pressure) type, choose it when your setpoint must stay at or below 0.4 MPa; for general circuits needing up to 0.9 MPa, the standard GR type is the match. The fitted round gauge reads in psi - MPa or bar scales are the other catalogue options. PT thread is standard on this model; G (BSPP) and NPT are orderable alternatives, and the included bracket covers wall or machine-frame mounting (GR also panels directly). Flow is published as curves, not a single rated number, so send us your application and we will confirm sizing from the datasheet before you order.
Quick checklist
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 publishes GR flow as performance curves, not as a single rated figure, so there is no one l/min or SCFM number we can honestly quote. Tell us your line pressure, setpoint and the flow your actuator or process needs, and we will confirm the sizing from the GR300 datasheet curves on request before you order.
L marks the low-pressure type. Its adjustment range tops out at 0.4 MPa, whereas the standard GR type adjusts up to 0.9 MPa. Choose this version when the downstream circuit must be limited to lower pressures; the rest of the decode is standard - 300 size, PT1/2 ports, PT thread, fitted round psi gauge, and a mounting bracket included.
