The AirTAC GFR60025LJF2WT AirTAC Filter Regulator NPT1 5um 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 GFR600-25T combines water and particulate filtration with pressure regulation in a single body, so one 1 in NPT connection handles both jobs on a compressed-air line. This configuration carries the 5 um filter element (code W) for finer cleaning than the standard 40 um grade, a differential-pressure drain that bleeds collected condensate automatically as flow passes through, a low-pressure regulator type, and an embedded square gauge reading in psi. At size 600 the bowl is aluminium alloy, and this unit is ordered without a mounting bracket.
This is a genuine AirTAC part in the largest of the four G-series frame sizes (200, 300, 400, 600). The family is offered with 40 um or 5 um filtration, differential-pressure, automatic or manual drains, square or square-plus-round gauges in MPa, psi or bar scales, and PT, G or NPT threads. Because AirTAC publishes flow only as curves rather than a single rated figure, we confirm flow and 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.

|---|---|
| 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). |
| 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. |
| 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.

Feeding the cylinder and gripper circuit of an end-of-line palletizer, where the 1 in NPT port matches the main drop leg and the regulator holds a steady low working pressure for the clamp-and-place sequence.
Conditioning the air that drives stopper gates, pushers and lift stations along a bottling conveyor, with the 5 um element protecting the small control valves that index each bottle position.
Supplying filtered, regulated air to a pilot plant or test-stand skid, where the psi-reading square gauge gives operators a direct local pressure reference and the differential drain keeps condensate off the instrumentation.
Work from the port step first: size 600 with a 1 in NPT port suits lines where your existing pipework is already at that size, and stepping up or down a frame changes both the connection and the flow capacity. Choose the drain next: differential-pressure (this unit) needs no timer or operator, automatic drains continuously, and manual drain suits points someone already walks past. Pick 5 um (this unit) when downstream valves or instruments want finer air than the standard 40 um element delivers. The square gauge here reads psi; MPa and bar scales are alternatives, and an external round gauge is optional. Thread is NPT on this code, with PT standard and G available to order; brackets are optional and omitted here.
One honest note on sizing: AirTAC publishes flow as curves, not a single rated number, and the adjustment range of the low-pressure regulator type is not stated as a single figure either. Ask us to confirm both 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 GFR600 as curves rather than a single rated figure, so we do not quote one number. Tell us your working pressure and the air demand of the equipment downstream, and we will confirm the sizing from the datasheet curves on request.
The W in the model code selects the 5 um filter element instead of the standard 40 um grade, giving finer removal of particulate and water carryover. The L code selects the low-pressure regulator type rather than the standard one; its exact adjustment range is not published as a single figure, so we confirm it from the datasheet on request.
