The AirTAC GFR60025ALJF3TK AirTAC Filter Regulator NPT 1 in 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 GFR60025ALJF3TK is an AirTAC GFR600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is built around a 1 in NPT port, an automatic drain that discharges collected condensate from the aluminium alloy bowl without manual attention, and a 40 um filter element. The low-pressure regulator is fitted with an embedded square gauge scaled in bar, and a reverse/check valve is included; the unit is supplied without a mounting bracket.
This is a genuine AirTAC part in the GFR600 size, the largest of the G-series filter regulator range (200, 300, 400 and 600). Across the series you can choose port sizes and thread forms, differential-pressure, automatic or manual drains, a 5 um element (code W), gauge scale options, and bracket or no-bracket mounting. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so ask us to confirm sizing and the low-pressure regulation range for 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.
| 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. |
| 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. |
| 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.

On a spray-booth supply header, the unit filters water and particles out of shop air and holds a steady low regulated pressure to the atomizing stations, while the automatic drain keeps condensate out of the bowl without operator rounds.
Bench and pilot-scale process rigs often need clean air at a gentle, stable pressure. This filter regulator conditions the supply line, the bar-scaled square gauge gives a local reading, and the fitted reverse/check valve blocks backflow toward the supply side.
On a beverage bottling line, conveyor stops, gates and pusher cylinders run on plant air. This unit cleans the supply, regulates it to the low pressure those actuators need, and the 1 in port suits a main header drop.
Size and port set the capacity: the GFR600 is the largest G-series filter regulator, and this unit carries a 1 in NPT port. Because flow is published as curves rather than a single rated figure, ask us to check the curve against your air demand before ordering. The other decodable choices are: drain type (differential-pressure is the default; automatic, as fitted here, discharges condensate on its own; manual, code M, suits a scheduled drain routine); filter grade (40 um standard, 5 um with code W); gauge (embedded square gauge standard, external round gauge optional, scales MPa, psi or bar); thread (PT is the standard, G and NPT are order options); bracket (code J deletes it); and the L low-pressure regulator type fitted here, whose exact adjustment range we confirm on request.
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 this series as curves, not as a single rated figure, so we do not quote a number. Send us your air demand and line pressure and we will confirm the sizing from the datasheet on request.
The A in the code selects an automatic drain, which discharges collected condensate from the aluminium alloy bowl without manual attention - useful on lines that run unattended. The series also offers the differential-pressure drain (the default) and a manual drain (code M) if you prefer a scheduled drain routine.
