The AirTAC AirTAC GR30015LC2G Air Pressure Regulator G1/2 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 GR30015LC2G is an AirTAC GR-series air pressure regulator: it does one job, holding your downstream pressure steady as upstream supply and air demand fluctuate. This is the low-pressure type, so the adjustment range tops out at 0.4 MPa - the right choice for circuits that must never see full-line pressure. The 300 size takes a G1/2 (BSPP) port, and the C code means an external round gauge with a psi scale is fitted so operators can read and set pressure directly at the unit. A mounting bracket is included, and the GR body is also panel-mountable. Maximum 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.
This is a genuine AirTAC part. The GR line spans sizes 200, 300, 400 and 600 with ports from 1/8" to 1", in standard or low-pressure types, with round or square gauges in MPa, psi or bar scales, optional reverse/check valve, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so send us your application and we will confirm the sizing and datasheet figures 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.

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.

Clamp and hold-down cylinders on carton-sealing or case-packing stations often need a gentle, capped pressure so product is held without crushing. This low-pressure GR with a psi gauge lets the line technician set and read the clamp circuit at a glance.
Gate, diverter and lid-lift actuators on food handling lines typically run at modest pressures. A dedicated low-pressure regulator at each drop keeps those actuators in their intended band, and the -20 to 70 C range suits chilled production areas.
Bench test rigs and lab pneumatic circuits need a stable, low setpoint that stays put through the day. This G1/2 regulator gives the rig its own adjustable supply, isolated from shop-air swings, with the round psi gauge mounted for easy reading.
Start with the port step: the 300 size carries a 1/2" port, and larger sizes move more air - match the size to your line's flow demand rather than to the pipe alone. This unit is the L low-pressure type, limited to 0.4 MPa outlet; if your circuit needs the full 0.05-0.9 MPa range, the standard GR type is the correct pick instead. Gauge choices are the embedded square gauge or this external round gauge, with MPa, psi or bar scales - the C2 code here gives you round with psi. Thread is G (BSPP) on this model; PT is the standard and NPT is an orderable option, so pick the one that matches your fittings. A bracket is included and the GR also panel-mounts; the K option adds a reverse/check valve if backflow protection is needed.
One honest note on sizing: AirTAC publishes GR flow only as curves, not as a single rated number, so we do not quote a flow figure here. Ask us to confirm the flow against your application 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-series flow only as performance curves, not as a single rated figure, so we do not state a l/min or SCFM number here. Tell us your line pressure, set pressure and expected air demand, and we will confirm the flow from the datasheet curves on request before you order.
The L in GR30015LC2G marks the low-pressure regulator type: its adjustment range tops out at 0.4 MPa instead of the standard type's 0.05-0.9 MPa. Choose it when the circuit must be capped at a modest pressure; choose the standard GR type when you need the full range. Everything else about the decode - G1/2 port, round psi gauge, included bracket - stays the same.
