The AirTAC GFR60025ALJC2T AirTAC Filter Regulator NPT1 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 automatic 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 GFR60025ALJC2T is an AirTAC GFR600 filter regulator: water and particulate filtration plus pressure regulation combined in a single body, sized for 1 in (NPT1) piping. This configuration carries the automatic drain, so accumulated condensate is discharged from the bowl without manual attention, and the standard 40 um filter element. It is the low-pressure regulator type, and the code specifies the external round pressure gauge with a psi scale. The 600 size bowl is aluminium alloy, and this unit is ordered without a mounting bracket.
This is a genuine AirTAC part. The GFR filter-regulator family spans sizes 200, 300, 400 and 600 with matching port sizes, a choice of drain type, a 40 um standard or 5 um (W) filter element, standard or low-pressure regulation, gauge style and scale options, G/NPT thread variants and bracket choices. Flow is published as curves rather than a single rating, so we confirm the datasheet and sizing figures on request before you order.

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.
| GFR600 | G-series filter regulator, 600 body — sets the port range. |
|---|---|
| 25 | Port size PT1". This body offers 20 = PT3/4", 25 = PT1". |
| A | Drain: Automatic 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. |
| T | NPT thread. PT is the default; G is BSPP and T is NPT. |
| (blank) | No reverse-flow valve (the default). |
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 a 1 in plant-air drop feeding a production hall, it removes water and pipe scale from the compressed air and holds a stable low-pressure supply to the header downstream.
Mounted ahead of the cylinder and valve bank on a packaged conveyor system, it filters condensate and particulate from the supply air and regulates the pressure to the drive circuit.
Placed in the supply line to big air-operated valve actuators on a process skid, it cleans the air and sets the actuator pressure with the round psi gauge giving a clear local reading.
Step up or down through the GFR sizes (200/300/400/600) to match the port and the flow your line needs - this unit is the 600 size with a 1 in NPT port, the largest step in the family. Choose the drain to suit access: automatic (as here) for unattended condensate discharge, manual where you prefer operator-controlled draining, or the differential-pressure default. Filter grade is 40 um standard; specify W for the 5 um element if downstream equipment demands finer filtration. This code is the low-pressure regulator type - confirm its adjustment range against your setpoint with us before ordering. Gauge options are the embedded square gauge or an external round gauge (as specified here) with MPa, psi or bar scales. Thread is PT as standard, with G (BSPP) and NPT as order options; brackets are optional, and this unit omits one. Because flow is published as curves rather than a single rated figure, 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. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes GFR flow as curves, not as a single rated figure, so we do not quote a number here. Tell us your line pressure and required flow and we will confirm the sizing from the datasheet on request before you order.
In the code GFR60025ALJC2T, C selects the external round gauge and 2 sets its scale to psi (MPa and bar scales are also available), while A selects the automatic drain, which discharges condensate from the aluminium alloy bowl without manual intervention. The embedded square gauge remains the standard alternative if you prefer it.
