The AirTAC GR60025LC2 AirTAC Pressure Regulator 1 in PT 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 GR60025LC2 is an AirTAC GR-series air pressure regulator in the large size 600 body, built for a 1 in PT port. It does one job only: holding downstream pressure steady on a compressed-air line. This is the low-pressure type, so the adjustment range goes up to 0.4 MPa, and it is supplied with a round pressure gauge scaled in psi plus a mounting bracket (the GR series is also panel-mountable). Max 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. There is no bowl, no filter and no drain on a GR - regulation only.
This is a genuine AirTAC part. The GR family spans sizes 200 to 600 with port options from 1/8 in to 1 in, standard or low-pressure regulation, embedded square or external round gauges in MPa, psi or bar scales, an optional reverse/check valve, and PT, G or NPT threads as order options. Flow is published as curves rather than a single rating, 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.

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.

Sealing and clamping cylinders on a carton or blister packaging machine often run best at gentle setpoints. This low-pressure regulator holds a stable, sub-0.4 MPa supply to the clamp circuit so parts are held firmly without crushing, with the psi gauge letting operators check the setting at a glance.
Air knives and blow-off nozzles that clear dust or chips from parts moving along a conveyor need steady, moderate pressure rather than full line pressure. The GR60025LC2 regulates the 1 in feed down to the low setpoint the nozzles were set up for, keeping the cleaning action consistent shift after shift.
Spray and atomizing heads in coating, humidifying or misting applications are sensitive to supply pressure drift. Feeding them through this low-pressure regulator keeps the atomizing air at the setpoint the nozzle recipe calls for, so droplet pattern and coverage stay repeatable.
Start with the port step: size 600 with a 1 in PT connection suits the largest lines in the GR range - step down to 300 or 400 if your piping is smaller, since flow capacity follows the size curve. This unit is the low-pressure (L) type, correct where the setpoint must stay at or below 0.4 MPa; choose the standard GR type if you need up to 0.9 MPa. The C2 suffix gives you an external round gauge in psi - pick scale 1 or 3 if your team reads MPa or bar. Thread is PT as standard; G (BSPP) and NPT are catalogue options you order by suffix. Bracket is included, and the GR body can also be panel-mounted. Because flow is published as curves and not a single rated figure, send us your line demand and we will confirm sizing against the datasheet before you order.
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 flow as performance curves rather than a single rated number, so we do not quote a flow, Cv or SCFM figure. Tell us your line size and air demand and we will confirm the sizing against the datasheet on request before you order.
The L in the code marks the low-pressure version of the GR series: its adjustment range tops out at 0.4 MPa instead of the standard type's higher range. It is the right choice for circuits designed to run at gentle setpoints, such as clamping, blow-off or atomizing air. Max inlet pressure is still 1.0 MPa (145 psi).
