The AirTAC GR40015LC2G AirTAC Regulator G1/2 Low-Pressure psi Gauge 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 GR40015LC2G is an AirTAC GR400 air pressure regulator for compressed air only. It does one job: holding a stable downstream pressure. This is the low-pressure type, so its adjustment range tops out at 0.4 MPa, and it is built on the 400 size with a G1/2 (BSPP) female port. A round pressure gauge with a psi scale is fitted so the setting can be read directly at the unit, and the mounting bracket is included; the GR body is also panel-mountable. There is no bowl, no filter and no drain on this unit - it is regulation only.
This is a genuine AirTAC part from the GR series, which spans the 200, 300, 400 and 600 sizes with port options from 1/8 in up to 1 in, standard or low-pressure regulation, embedded square or external round gauges, and PT, G or NPT threads. 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. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures for 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.
| GR400 | G-series pressure regulator, 400 body — sets the port range. |
|---|---|
| 15 | Port size PT1/2". This body offers 10 = PT3/8", 15 = PT1/2". |
| 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). |
| C | Gauge shape: Round. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| G | G (BSPP) 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.
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.

On a packaging or converting line, hot-melt and cold-glue applicators need a gentle, steady air signal to the pump and head. This low-pressure regulator holds that setting below 0.4 MPa with a psi gauge readable at the machine.
Conveyor take-up cylinders and web-guiding actuators on printing and converting lines run best at low, stable pressure. The GR40015LC2G regulates that circuit, with the included bracket mounting it beside the frame.
Fixture clamps and soft-grip cylinders on an assembly bench need repeatable low-pressure holding force. This regulator sets the circuit once, and the round psi gauge lets an operator verify the setting at a glance.
Start with the port step: the 400 size carries a 1/2 in port, and larger sizes move more air - match the size to the flow your line needs rather than to the pipe alone. Choose the low-pressure L type only when your setpoint sits at or below 0.4 MPa; for higher setpoints up to 0.9 MPa the standard GR is the right pick. This unit arrives with a round psi-scale gauge; square-gauge and other scale options exist in the series. Thread is G (BSPP) here, with PT as the standard and NPT available to order. Bracket is included and the GR is also panel-mountable. Flow is published as curves, not a single rating, so send us your application details and we will confirm sizing against 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-series flow as curves, not as a single rated figure, so there is no one number we can honestly quote. Send us your line pressure, setpoint and the cylinders or actuators you are feeding, and we will confirm the sizing from the datasheet curves before you order.
The L in the code marks the low-pressure type, whose adjustment range tops out at 0.4 MPa; for higher setpoints choose a standard GR. The C2 in this code means a round gauge with a psi scale is fitted, so the setting is read directly in psi at the unit.
