The AirTAC GR60025LF1T AirTAC Low-Pressure Regulator NPT1 in 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 GR60025LF1T is an AirTAC GR600 air pressure regulator built for 1 in (NPT1) pipework, and it does one job only: holding a steady downstream air pressure from a varying supply. This is the low-pressure (L) version, so the setting range goes up to 0.4 MPa, and it comes with the embedded square gauge scaled in MPa so the set point can be read and adjusted directly at the unit. Max working (inlet) pressure is 1.0 MPa (145 psi), the operating temperature range is -20 to 70 C, and the unit is supplied with a mounting bracket; GR bodies are also panel-mountable.
This is a genuine AirTAC part from the GR series, which spans sizes 200, 300, 400 and 600 with ports from 1/8 in up to 1 in, in PT (standard), G (BSPP) or NPT thread, with standard or low-pressure regulation, optional reverse/check valve (K) and gauge scales in MPa, psi or bar. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing for your application 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.
| 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). |
| F | Gauge shape: Square. C is round, F is square. |
| 1 | Gauge scale: MPa. 1 is MPa, 2 is psi, 3 is bar. |
| T | NPT 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.

Set downstream pressure precisely for the large air cylinders that index, gate and push containers along the line, where the process calls for gentle low-pressure settings rather than full line pressure.
Feed a low-pressure air header used for part-holding assist and clearing swarf from fixtures, keeping the header pressure stable even as upstream compressor loading swings.
Regulate the supply to pneumatic clamping fixtures where the workpiece requires a low holding pressure, with the MPa gauge letting operators set and verify the clamp pressure at the unit.
Start with the pipe and the flow: the GR600 size with its 1 in port suits the largest lines in the range, and stepping up a size gives more flow capacity at the same pressure drop - we can check the flow curve against your demand before you order. Then choose the regulation type: this L-coded unit is the low-pressure type with settings up to 0.4 MPa; if you need settings up to 0.9 MPa, pick the standard GR version instead. Remaining decodable choices are the gauge scale (MPa, psi or bar, round external gauge optional), the thread (PT is the standard; G and NPT are order options, as selected here), the reverse/check valve (K) and the bracket.
One honest note on sizing: AirTAC publishes GR flow as curves, not as a single rated number, so we do not quote a flow figure here. Tell us your line size, inlet pressure and required downstream flow, and we will confirm the right size from the datasheet on request.
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 regulator flow as curves, not as a single rated figure, so we do not state a flow number here. Tell us your line size, inlet pressure and required downstream flow, and we will confirm the sizing from the datasheet on request.
L marks the low-pressure regulator type, with a setting range up to 0.4 MPa. Choose it when your process must run at low downstream pressures; for settings up to 0.9 MPa, order the standard GR version instead. Both share the same size, port and thread options.
