The AirTAC GFR60025LJF3WTK AirTAC Filter Regulator NPT1 5 um 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 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 GFR60025LJF3WTK is a size-600 GFR filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This configuration is built around a 1 in NPT port for high-flow main-line air, a 5 um filter element (code W) for finer protection downstream, a differential-pressure drain that bleeds collected condensate automatically as flow passes through, and a low-pressure regulator type (code L). It ships as coded with an embedded square gauge scaled in bar, a reverse/check valve fitted, and no mounting bracket. The size-600 bowl is aluminium alloy, and the maximum working (inlet) pressure is 1.0 MPa (145 psi) with a -5 to 70 C (non-freezing) operating range.
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, and options across drain type (differential-pressure, automatic or manual), filter grade (40 um standard, 5 um with W), gauge scale (MPa, psi or bar), thread (PT standard, with G and NPT as order options) and bracket. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

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

At the 1 in NPT take-off feeding a bottling or packaging hall, this unit filters water and particulate from the main supply and holds a reduced, stable pressure for the downstream actuators, while the differential-pressure drain keeps condensate moving out without operator rounds.
On a mechanical press or fixture-clamping circuit where clamping force is set by air pressure, the regulator section lets the setter dial in the working pressure on the bar-scaled square gauge, and the 5 um element protects the directional valves feeding the clamps.
Feeding positioners, transducers and small actuated valves on a process skid, the finer 5 um grade and stable regulated output suit control components, and the reverse/check valve helps hold the downstream circuit if supply pressure is interrupted.
Step up or down through the GFR sizes (200 / 300 / 400 / 600) against the flow your line needs; this is the 600, the largest of the family, with a 1 in port. Because the element here is the finer 5 um grade (W), it suits circuits feeding sensitive valves and instruments; the standard grade is 40 um if coarse protection is enough. The differential-pressure drain is the default and needs no operator attention; specify automatic (A) or manual (M) drain codes if your maintenance routine prefers them. The square gauge is fitted here in bar; MPa and psi scales are available, and an external round gauge is an option. Thread is NPT on this coded unit (PT is the standard, G and NPT are order options), and the J code means no mounting bracket. One honest note before you order: flow is published as curves, not a single rating, so send us your application details 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. 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 curves, not as a single rated number, so we do not quote a l/min or SCFM figure on the page. Tell us your line pressure, downstream demand and allowable pressure drop, and we will confirm the sizing from the datasheet on request before you order.
L marks the low-pressure regulator type, as opposed to the standard version. The exact regulation range for the low-pressure type is not published in the sheet we work from, so we confirm it on request. What is fixed for this unit: maximum inlet pressure of 1.0 MPa (145 psi), a 5 um filter element, differential-pressure drain, and a square gauge scaled in bar.
