The AirTAC GFR60025LJC2K AirTAC Filter Regulator 1 in PT, Low-Pressure is a genuine G-series filter regulator: water separation, 40 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has PT1" ports, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The AirTAC GFR60025LJC2K is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is the low-pressure type, built for circuits that run below standard line pressure, with a 1 in PT (BSPT-type) port for high-flow supply lines. The 40 um element is the standard filtration grade, the differential-pressure drain bleeds collected condensate automatically as flow passes through, and the fitted reverse/check valve holds downstream settings if upstream supply is interrupted. An external round gauge with a psi scale is fitted so operators can read the regulated pressure directly. The size-600 aluminium alloy bowl suits demanding plant environments where polycarbonate is not preferred.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and options including automatic or manual drains, a 5 um element (code W), square or round gauges with MPa, psi or bar scales, and G or NPT threads in place of the PT standard. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet and sizing for your application before ordering.

Specifications follow the official AirTAC G-series air-preparation data. The regulating band is set by the drain type: automatic and differential-pressure drains regulate 0.15 - 0.9 MPa, a manual drain regulates 0.05 - 0.9 MPa. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. Air must not freeze in the unit. Flow curves, weight and outline dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.

| C | Gauge shape: Round. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |

Field order is size, port, drain, type, bracket, gauge, shape, scale, grade, thread, reflux — a blank position takes the default. Example: GFR300-08 is a 300 body, PT1/4", differential drain, standard type, bracket included, gauge fitted, 40 µm, PT thread, no 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. The GFR600 uses an aluminium-alloy bowl; the 200, 300 and 400 bodies use PC.

Installed at the take-off point of a factory 1 in compressed-air main, it filters water and scale from the supply and holds a reduced, stable pressure for the downstream distribution legs.
Feeding a low-pressure clamping or forming circuit on a production machine, it delivers clean air and lets the operator set and read the working pressure on the fitted psi gauge.
On a packaging or material-handling line with air-driven conveyor stops and pushers, it conditions the supply and protects actuators from pressure surges, with the check valve holding settings during supply dips.
Start with the port step: this unit is size 600 with a 1 in PT port, the largest in the GFR range, intended for high-flow mains. Match the size to the air demand of the circuit rather than to the pipe alone, and ask us to confirm sizing against the published flow curves before ordering. Drain choice matters: this unit uses the differential-pressure drain (the default), while automatic (A) and manual (M) versions are available. The 40 um element is standard; specify 5 um (code W) if finer particulate removal is needed. This is the low-pressure type (L); the exact regulation range for this variant is not published, so confirm it with us. The round psi gauge is fitted here; embedded square gauges and MPa or bar scales are alternatives. PT is the standard thread, with G and NPT available as order options, and this unit is supplied without a mounting bracket (code J).
Quick checklist
The aluminium-alloy bowl on the GFR600 suits harsher environments than a PC bowl. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for this series as curves, not as a single rated figure, so we do not quote a number. Send us your air demand and line conditions and we will confirm the flow and sizing from the datasheet before you order.
The L code identifies the low-pressure regulator variant, intended for circuits that run below standard line pressure. The exact regulation range for this variant is not published in our sheet, so please confirm the range with us for your setpoint. The unit also carries a reverse/check valve (K), a round psi gauge, and the differential-pressure drain.
