The AirTAC GR60025LC3T AirTAC Air 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 GR60025LC3T is an AirTAC GR-series air pressure regulator: it does one job, holding downstream pressure steady at the set point regardless of swings in supply pressure. This is the 600 size, the largest in the GR range, with a 1 in NPT port for high-volume air lines. The L in the code marks the low-pressure type, so it regulates up to 0.4 MPa - suited to circuits that must not see full-line pressure. A round external gauge with a bar scale is fitted, so the set pressure is read directly at the unit.
This is a genuine AirTAC part. The GR family spans 200, 300, 400 and 600 sizes with ports from 1/8 in to 1 in, standard and low-pressure types, and a choice of gauge style and scale (MPa, psi or bar). It carries a maximum inlet pressure of 1.0 MPa (145 psi) and works from -20 to 70 C, the widest temperature window in the G-series. Flow is published as curves rather than a single rated figure, so we confirm the datasheet and sizing 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.

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.

Clamp and hold-down cylinders on carton and tray packaging lines often run at reduced pressure to avoid crushing product. The low-pressure type regulates up to 0.4 MPa, and the bar-scale round gauge lets the line technician set and verify the clamp pressure at the machine.
Spray guns and air-assisted applicators need a steady, moderate supply pressure for consistent atomisation. A 1 in port regulator placed at the booth manifold holds the set point as other drops on the same compressor cycle, with the gauge reading in bar for straightforward setting.
Looms and fabric-handling equipment use low-pressure air for shed control and material transport. The 600 size with a 1 in NPT connection sits on the main drop to a machine group, keeping the working pressure stable across a shift while the wider -20 to 70 C range suits unheated plant rooms.
Start with the port step: GR comes in 200/300/400/600 sizes on 1/8 in to 1 in ports, and the 600 size with its 1 in NPT connection is the choice when the line volume is large - match the port to the main air line rather than stepping down. Then set the regulation band: this unit is the L low-pressure type, regulating up to 0.4 MPa, so it belongs on circuits whose working pressure sits well below full line pressure; for settings up to 0.9 MPa the standard GR type is the alternative. Gauge options are the embedded square gauge or an external round gauge, in MPa, psi or bar scales - this unit carries the round gauge in bar. Thread is NPT here; PT is the catalogue standard and G (BSPP) is also orderable. A mounting bracket is included and GR is also panel-mountable. Flow is published as curves, not a single rating, so ask us to confirm sizing against your application before ordering.
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 regulator flow as curves, not as a single rated figure, so we do not quote a number here. Send us your line pressure, set pressure and expected air demand and we will confirm the datasheet and check the sizing against your application before you order.
The L in the code is the low-pressure type: it regulates up to 0.4 MPa instead of the standard GR range. Choose it for circuits whose working pressure is moderate, such as clamping or spraying; for settings up to 0.9 MPa, order the standard type instead. Everything else on this unit - 600 size, 1 in NPT port, round bar-scale gauge - stays as decoded.
