The AirTAC GFR60025LJC2GK AirTAC Filter Regulator G1 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 GFR60025LJC2GK is an AirTAC GFR600 filter regulator: filtration and pressure regulation combined in a single body. It removes water and particulate from compressed air with a 40 um element, drains collected condensate automatically via the differential-pressure drain, and regulates downstream pressure in the low-pressure configuration. This unit is built in the largest frame of the range with a G1 (1 in) port in G (BSPP) thread, a reverse/check valve fitted, a round external gauge reading in psi, and no mounting bracket. At size 600 the bowl is aluminium alloy.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drain, a 40 um standard or 5 um (W) filter element, gauge and scale options, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so ask us to confirm the figures 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.

|---|---|
| 25 | Port size PT1". This body offers 20 = PT3/4", 25 = PT1". |
| (blank) | Drain: Differential-pressure drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| J | Supplied without bracket. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| G | G (BSPP) thread. PT is the default; G is BSPP and T is NPT. |
| K | Reverse-flow (reflux) valve fitted. |
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 feeding a packaging machine's air mains, the unit strips water and pipe-scale from the shop supply and holds a gentle regulated pressure so carton sealers and case erectors cycle without pressure spikes.
Mounted ahead of diaphragm-actuated process valves, the low-pressure regulator holds the steady, reduced supply pressure positioners and I-to-P converters need, while the 40 um element keeps grit out of small internal orifices.
On a machining cell using air-assisted clamps and swing cylinders that must not be slammed at full line pressure, the unit filters the supply and regulates it down to the fixture maker's specified setting, with the check valve holding the circuit if upstream pressure dips.
Size and port set the capacity: GFR600 is the largest frame in the family, with a 1 in port suited to high-consumption supply lines - match the frame to the flow your circuit needs. Choose the drain: differential-pressure (as here, discharging when the pressure differential across the element rises), automatic (continuous), or manual (periodic). Choose the element: 40 um standard or 5 um (code W) for finer protection. This unit is the low-pressure type, intended where setpoints below the standard regulator range are needed; the exact range for the low-pressure version is not published, so confirm it with us. Gauge options are the embedded square gauge or an external round gauge in MPa, psi or bar scales - this unit carries a round psi gauge. Thread is PT as standard with G and NPT as order options; this unit is G (BSPP). A mounting bracket is optional (this unit has none), and a reverse/check valve can be fitted (this unit has one). Flow is published as curves, not a single rating - ask us to confirm sizing against your application before ordering.
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 the GFR series as characteristic curves rather than a single rated figure, so we do not quote a rated flow, Cv or SCFM number. Tell us your line pressure, set pressure and expected air consumption, and we will confirm the sizing against the datasheet curves for this exact model before you order.
The L in the code marks the low-pressure regulator version, intended for applications where the set pressure is below what the standard regulator version covers; the exact range for the low-pressure type is not published, so confirm it with us. The drain is differential-pressure type (blank position in the code): condensate collected in the aluminium bowl discharges automatically when the pressure drop across the 40 um element reaches the drain's threshold, with no manual draining needed under normal duty.
