The AirTAC GFR60025ALJF2W AirTAC Filter Regulator PT1, 5 um, Auto Drain is a genuine G-series filter regulator: water separation, 5 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 AirTAC GFR600 series combines water and particulate filtration with pressure regulation in a single body, and this GFR60025ALJF2W is configured for a 1 in PT port. It carries a 5 um filter element (code W) for finer filtration than the 40 um standard, an automatic drain that discharges collected condensate without operator attention, and a low-pressure type regulator for circuits that run below standard working pressures. The bowl on the 600 size is aluminium alloy, and the embedded square gauge reads in psi.
This is a genuine AirTAC part. The GFR family spans sizes 200 to 600 with ports from 1/8 in to 1 in, drain choices of differential-pressure, automatic or manual, filter grades of 40 um standard or 5 um optional, and gauge scales in MPa, psi or bar. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures for your application.

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). |
| F | Gauge shape: Square. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| (blank) | PT 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.

On a machining centre with large pneumatic clamps and fixtures, this unit filters water and swarf-laden shop air and regulates pressure to the clamping circuit at the 1 in port, with the 5 um element protecting directional valves and cylinders.
On a bottling or canning line where groups of actuators run grippers and pushers off a main header, this filter regulator cleans the air and holds a steady setting, while the automatic drain keeps condensate out of the circuit without daily attention.
For a packaging machine section that needs a gentler setting than the main plant pressure, the low-pressure type regulator in this unit lets the circuit run at reduced pressure, with the square psi gauge giving a direct local readout.
Step through the 200/300/400/600 sizes to match the port and the flow your line needs; this unit is the 600 size with a 1 in PT port. Choose the drain to suit access: automatic here, or manual or differential-pressure where you prefer. Pick 40 um for general protection or 5 um (this unit) for finer filtration, and set the gauge scale to MPa, psi or bar. Thread is PT as standard, with G and NPT available as order options; this version has no mounting bracket. 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.
Flow for the GFR600 series is published as curves rather than a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the flow and the full datasheet figures on request.
This configuration uses an automatic drain, which discharges collected condensate from the bowl without operator attention - useful where the unit is mounted in a hard-to-reach position. The same 600 size is also available with a manual or a differential-pressure drain if that suits your maintenance routine better.
