The AirTAC GR60025LJF1TK 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 GR60025LJF1TK is an AirTAC GR-series air pressure regulator: it does one job, holding downstream pressure steady in a compressed-air line. This is the 600 size with a 1 in NPT port, built as the low-pressure type, so its adjustment range tops out at 0.4 MPa - the right choice where the process needs a gentle, stable setting rather than full line pressure. It carries the embedded square pressure gauge scaled in MPa, a reverse (check) valve fitted, and no mounting bracket, with the body also suitable for panel mounting. Like all GR units it handles a maximum inlet pressure of 1.0 MPa (145 psi) and works from -20 to 70 C, the widest temperature window in the G family.
This is a genuine AirTAC part. The GR line spans four sizes (200, 300, 400, 600) with ports from 1/8 in to 1 in, standard or low-pressure regulation, gauge scale options, an optional reverse valve, and G (BSPP) or NPT threads as order options alongside the PT standard. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures for your application before ordering.

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.

|---|---|
| 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. |
| J | Supplied without bracket. |

| 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. |
| 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.

Pneumatic hold-down clamps on a carton-sealing line often need a soft, repeatable setting well below full line pressure. This low-pressure GR regulator, set within its 0.4 MPa range, holds the clamp circuit steady so delicate packs are gripped without crushing, with the check valve keeping the setting stable against upstream fluctuation.
Atomising air to a paint-spray booth header must sit at a low, constant pressure for consistent droplet formation. A 1 in NPT regulator at the booth inlet, with the MPa gauge in view for the operator, gives the booth tech a direct read and a stable setpoint across a shift.
A bank of air-jet looms draws from a shared plant-air drop; each bay needs its own regulated feed so one machine's demand spikes do not upset its neighbours. A 600-size GR at the bay drop, panel-mounted at the manifold, gives maintenance a dedicated low-pressure setting and gauge for that section.
Start with the port step: the GR sizes run 200 through 600 with ports from 1/8 in to 1 in, and the 600 size with its 1 in connection is the largest in the range - match it to your line size and required flow, and we will confirm the flow curve against your demand. Next, pick the regulator type: this low-pressure version adjusts up to 0.4 MPa, while the standard type covers 0.05-0.9 MPa, so choose low-pressure only if your setpoint stays within that ceiling. Gauge scale can be MPa, psi or bar, and the thread here is NPT with G (BSPP) available as an order option - PT is the catalogue standard. A reverse valve is fitted on this unit, and the bracket is omitted, with panel mounting available. Because flow is published as curves and not a single rating, ask us to confirm sizing against your application 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 regulator flow as performance curves rather than a single rated figure, so we do not quote a rated flow, Cv or SCFM number for this unit. Tell us your line size and air demand and we will confirm the flow figures from the datasheet against your application on request, before you order.
L marks the low-pressure type: the adjustment range tops out at 0.4 MPa instead of the standard GR range of 0.05-0.9 MPa. Choose this version when your setpoint sits comfortably below 0.4 MPa and you want finer control in that band; choose the standard type if you need to regulate higher. Maximum inlet pressure is 1.0 MPa (145 psi) either way, and this unit works from -20 to 70 C.
