The AirTAC GFR60025LJC3WT AirTAC Filter Regulator NPT 1 in Low-Pressure 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 GFR60025LJC3WT is a size-600 GFR filter regulator: water and particulate filtration plus pressure regulation in a single body. This configuration is built for a 1 in NPT port, carries the fine 5 um filter element (code W) instead of the 40 um standard element, and is the low-pressure regulator type rather than the standard one. The bowl on this size is aluminium alloy, drainage is handled automatically by the differential-pressure drain, and a round gauge with a bar scale is fitted so the set pressure can be read directly at the unit. No mounting bracket is included and no reverse/check valve is fitted.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in up to 1 in, and can be ordered with a choice of drain type, filter grade, gauge style and scale, thread (PT standard, with G and NPT as order options) and bracket. AirTAC publishes flow as curves rather than a single rated figure, so ask us and we will confirm the flow and datasheet figures for this exact model against 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.

|---|---|
| 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. |
| 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. |
| (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.

Filtered, low-pressure regulated air feeding an air-over-oil intensifier or pneumatic clamping fixture on a forming press, with the 5 um element protecting the intensifier seals and the bar-scale gauge showing the set pressure at the unit.
Point-of-use preparation for a paint line spray booth, where the 5 um filtration helps keep water and particulates out of the finishing air and the low-pressure regulator type matches the modest working pressures a spray application runs at.
Supplying a packaging line's carton sealer or case erector cylinders, where the 1 in port serves the machine's main air drop and the differential-pressure drain sheds accumulated condensate automatically between shifts.
Step up through the GFR sizes (200/300/400/600) and their matching ports as your required air flow grows; this is the largest size, with a 1 in port, for the heaviest duty points of use. Choose the filter grade to match downstream sensitivity: 40 um is the standard element, while this unit's 5 um element (code W) suits finer protection. Pick the drain type for how the unit is serviced: differential-pressure (as fitted here) drains automatically, while automatic and manual drains are order options. Gauge style and scale (embedded square or external round; MPa, psi or bar - this unit has a round bar-scale gauge) and thread (PT standard, G or NPT to order) are also decodable choices, as is the bracket. Note that this is the low-pressure regulator type; its exact adjustment range is not published, so confirm it with us. Because flow is published as curves rather than 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. 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 GFR series as curves, not as a single rated number, so we will not quote you a made-up figure. Tell us your application and required flow, and we will confirm the figures from the datasheet for this exact model before you order.
The W code in GFR60025LJC3WT selects the optional 5 um filter grade in place of the 40 um standard element. Choose 5 um when the downstream equipment - valves, cylinders, spray equipment - needs finer protection; choose the standard 40 um grade when general water and particulate removal is enough. Both grades are orderable across the GFR range.
