The AirTAC GR60025LC2K AirTAC Air Regulator PT1 in Low-Pressure Type 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" 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 GR60025LC2K is an AirTAC GR600 series air pressure regulator, built purely for pressure regulation: no filter, no bowl and no lubrication. This 600-size unit carries PT1 (1 in) ports with standard PT thread, and the L in the code marks it as the low-pressure type, holding downstream pressure up to 0.4 MPa. It is supplied with an external round gauge scaled in psi, a reverse (check) valve fitted, and a mounting bracket included; the GR series is also panel-mountable. Maximum working (inlet) pressure is 1.0 MPa (145 psi), and the operating temperature range is -20 to 70 C - wider than the rest of the G series.
This is a genuine AirTAC part. The GR family spans sizes 200, 300, 400 and 600, with port options from 1/8 in to 1 in, standard or low-pressure regulation, gauge choices (embedded square as standard, external round optional) in MPa, psi or bar scales, an optional reverse valve, and G (BSPP) or NPT threads as order options. Flow figures are 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.
| GR600 | G-series pressure regulator, 600 body — sets the port range. |
|---|---|
| 25 | Port size PT1". This body offers 20 = PT3/4", 25 = PT1". |
| 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. |
| (blank) | PT thread. PT is the default; G is BSPP and T is NPT. |
| K | Reverse-flow (reflux) valve fitted. |
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 carton-sealing or case-packing line where pneumatic clamps and hold-downs are specified to run at gentle setpoints, this low-pressure GR600 regulator holds the downstream pressure steady at 1 in ports, with the check valve holding the setting against upstream dips.
Large pneumatic actuated butterfly and knife-gate valves on a treatment plant skid often need a soft, low setpoint supply. This 1 in regulator, panel-mountable with its included bracket, sits on the actuator air line and keeps the actuator pressure where the valve engineer set it.
Bottle-rinsing and label-drying blow-off headers run best at low, stable pressure. Fed at 1 in PT ports, this GR600 low-pressure regulator lets the line operator dial the header down to the setpoint and read it directly on the round psi gauge.
Step through the real, decodable choices: pick the size (200/300/400/600) and its port against the pipe and the flow your line needs - this unit is the 600 size at 1 in. The L code makes it a low-pressure regulator (up to 0.4 MPa); if your circuit needs the standard range up to 0.9 MPa, choose a GR without the L. Choose the gauge scale (MPa, psi or bar) and square vs round style; this configuration ships with a round psi gauge. Thread is PT as standard, with G (BSPP) and NPT available to order. A bracket is included, and the K code adds a reverse (check) valve. Flow is published as curves, not a single rating, so ask us to confirm sizing against your application before ordering.
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 curves, not as a single rated figure, so we do not quote a number here. Send us your line pressure, setpoint and expected air demand, and we will confirm the flow from the GR600 datasheet curves on request before you order.
The L marks the low-pressure type of the GR series: it regulates up to 0.4 MPa instead of the standard GR range up to 0.9 MPa. Maximum inlet pressure is still 1.0 MPa (145 psi), and the C2 code adds the external round gauge scaled in psi, while K adds the reverse (check) valve.
