The AirTAC GFR60025LJF3T 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 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 GFR60025LJF3T is an AirTAC GFR-series filter regulator: one body that removes water and particulate from compressed air and holds downstream pressure. This size 600 unit carries a 1 in NPT port, the low-pressure regulator type, the standard 40 um filter element and a differential-pressure drain that bleeds accumulated condensate as the pressure differential rises. An embedded square gauge reading in bar is fitted, the bowl is the aluminium alloy specified for the 600 size, and this J-coded unit comes without a mounting bracket. Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C, non-freezing.
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, differential-pressure, automatic or manual drains, a 40 um standard or 5 um (code W) element, gauge and scale choices, and G (BSPP) or NPT threads as order options against the PT standard. Flow for this series is published as curves rather than a single rating, so ask us to confirm the datasheet figures for your application before ordering.

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. |

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

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.

Feeding filtered, regulated air to the filler and capper valve banks on a beverage bottling line, where the 1 in port serves a high-draw header and the differential-pressure drain keeps condensate out of the valves.
Holding steady, lower-than-standard pressure on the clamp and hold-down cylinders of a sheet-metal forming press, where the low-pressure regulator type matches the circuit's working band.
Supplying the diverter and stopper cylinders that sort parcels on a distribution-centre conveyor, with the 40 um element protecting the directional valves from water and debris.
Every choice on this code is decodable. The 600 size with its 1 in NPT port is the top step of the range - step up to it when your line's flow demand sits above what the 200-400 sizes serve, matching size to required flow using the published curves. The L code makes this the low-pressure regulator type, for circuits that hold pressures below the standard type's range; the exact adjustment range is not published in our data, so confirm it with us. The 40 um element is the standard grade - specify W for 5 um filtration. Drain is differential-pressure here, with automatic (A) and manual (M) as alternatives. The gauge reads bar; MPa and psi scales exist. Thread is NPT, a catalogue option against the PT standard, and no mounting bracket is fitted.
One honest routing note: flow is published as curves, not a single rating, so 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 figure, so we do not quote a number. Tell us your application and we will confirm the relevant flow and datasheet figures for you on request before you order.
L marks the low-pressure regulator type, intended for circuits that hold pressures below the standard type's range. The exact adjustment range for this type is not published in our data, so confirm it with us; the standard type's range is documented separately in the series.
