The AirTAC GR60025LF2TK AirTAC Pressure Regulator NPT1 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" 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 GR60025LF2TK is an AirTAC GR-series air pressure regulator in the size-600 frame with a 1 in NPT port. It is the low-pressure (L) type, so its regulation range tops out at 0.4 MPa, and it comes with an embedded square gauge scaled in psi, a built-in reverse (check) valve and a mounting bracket included (the GR can also be panel-mounted). It regulates only: there is no filter, bowl or drain in this unit.
This is a genuine AirTAC part. The GR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, standard or low-pressure types, gauge scales in MPa, psi or bar, and G, NPT or PT threads to order. 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 series. Flow is published as curves rather than a single rating, so ask us to confirm figures from the datasheet 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). |
| F | Gauge shape: Square. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| T | NPT 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 pneumatic clamping fixture or press that works below 0.4 MPa, this regulator holds the cylinder pressure steady at the set point while the check valve holds the downstream side if supply dips.
A size-600 regulator with a 1 in port suits the main air drop feeding a packaging line's valves and actuators, giving operators a local psi gauge and a stable set point at the machine.
Low-pressure air knives, looms and blow-off nozzles need gentle, repeatable pressure control; the L-type range up to 0.4 MPa matches those circuits without over-specifying the valve.
For a GR regulator the real choices are size and port, regulator type, gauge and thread. Size 600 with the 1 in port is the largest step in the family, so match it to the pipe diameter of your supply line; the next size down is 400 with a 3/4 in port. This unit is the low-pressure (L) type with a regulation range up to 0.4 MPa - if your process needs up to 0.9 MPa, choose the standard type instead. The square gauge here reads in psi; MPa and bar scales are also available, and an external round gauge is an option. Thread is NPT on this code; PT is the standard and G (BSPP) can be ordered. The reverse/check valve (K) is fitted and the mounting bracket is included.
Flow for the GR series is published as curves, not a single rated figure, so send us your application details and we will confirm sizing from the datasheet before you order.
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 rather than a single rated figure, so we do not quote a number here. Send us your line size and air demand and we will confirm the sizing from the datasheet on request.
The L in the code means the regulation range tops out at 0.4 MPa instead of the standard GR range. It suits circuits that run gently and need fine control at low settings; for up to 0.9 MPa use the standard type. Maximum inlet pressure is still 1.0 MPa (145 psi).
