The AirTAC GFR600-25 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 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 GFR600-25 is an AirTAC GFR600 filter regulator: a single body that removes water and particulate from compressed air and then regulates downstream pressure. This 600-size unit carries a 1 inch PT port, an automatic drain that bleeds condensate from the aluminium alloy bowl without manual attention, a 40 um standard filter element, and the low-pressure regulator type for applications set below standard line pressure. The embedded square gauge is fitted and reads in psi, and the unit is supplied without a mounting bracket.
This is a genuine AirTAC part. The GFR family spans sizes 200 to 600 with port options from 1/8 in to 1 in, drain choices (differential-pressure, automatic or manual), a 5 um element option (code W), gauge scales in MPa, psi or bar, and G or NPT thread options to order. Flow is published as curves rather than a single rated figure, so ask us and we will confirm the datasheet figures for your application on request.

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. |
| (blank) | Filtering grade 40 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 paint booth air line, the GFR600-25 strips water and particulate before atomizing air and holds the gun supply at the reduced pressure the low-pressure regulator type is built for, with the automatic drain keeping the aluminium bowl clear during long shifts.
Air-jet weaving machines need clean, steady air at modest pressure. This unit filters the mill air supply to 40 um and regulates it down with the psi square gauge giving operators a direct local readout at the loom.
On a filling and capping line, the 1 in PT port suits the main drop leg, the filter protects downstream valve actuators from condensate and grit, and the low-pressure regulator type holds the gentle setpoints those gripper and clamp circuits need.
Size and port step up together: 200 through 600, with ports from 1/8 in to 1 in, so match the 600 size and its 1 in PT connection to the pipe and the air demand of the machine. Drain type is a real choice: automatic (this unit) drains the aluminium bowl by itself, manual needs an operator, and differential-pressure drain is the default alternative. Filter grade is 40 um standard; specify code W for 5 um where finer particulate capture matters. Gauge options are the fitted embedded square gauge (psi on this unit, MPa or bar available) or an optional external round gauge. Thread is PT as standard, with G (BSPP) and NPT as order options, and a bracket can be added if this no-bracket configuration needs one.
One honest note before you order: AirTAC publishes flow as curves, not as a single rated number, so send us your line conditions and we will confirm sizing against the datasheet before you commit.
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 flow for the GFR600 as performance curves rather than a single rated figure, so we do not quote a number here. Tell us your line pressure and air demand and we will confirm the datasheet flow figures for this exact configuration on request.
The A in the code GFR60025ALJF2 selects the automatic drain, which ejects collected condensate from the aluminium bowl without operator attention - useful on unattended or high-humidity installations. Manual drain and the default differential-pressure drain are alternative decodes in the same series if you prefer a different service routine.
