The AirTAC GFR60025ALJF1TK 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 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 AirTAC GFR60025ALJF1TK is a GFR600 filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This size 600 unit has 1 in NPT ports, an automatic drain that expels collected condensate without manual attention, a 40 um standard filter element, and a low-pressure regulator fitted with an embedded square gauge reading in MPa. A reverse/check valve is fitted, the 600-size bowl is aluminium alloy, and no mounting bracket is included on this code.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, drain choices (differential-pressure, automatic or manual), an optional 5 um element (code W), gauge scales in MPa, psi or bar, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so ask us to confirm sizing and 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.
| 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. |
| 1 | Gauge scale: MPa. 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.

Supplies filtered, low-pressure regulated air to air knives that dry containers before labelling, while the automatic drain keeps accumulated condensate out of the circuit without operator attention.
Feeds analytical and test-bench instruments that need a low downstream pressure setting, with the 40 um element stopping pipe-scale and particulate from reaching sensitive internal valves.
Provides filtered, low-pressure regulated air to diverter gates and stoppers, with the fitted check valve holding the downstream circuit if the upstream supply dips.
Size and port set the air capacity: this is the largest GFR size, 600, with 1 in NPT ports, chosen when the circuit's flow demand is highest - we can check the published flow curves against your consumption before you order. The other decodable choices are drain type (this unit is automatic; manual and differential-pressure drains are available), filter grade (40 um standard here, 5 um with code W), gauge (square MPa gauge fitted here; psi or bar scales and an external round gauge are options), thread (PT is the standard; G and NPT are order options), and bracket (not included on this code, code J). The low-pressure type (code L) is selected when the downstream setting sits below the standard regulator's range; its exact adjustment range is not published, so confirm it with us.
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 a single rated figure, so we do not quote a number here. Send us your line pressure and air consumption and we will confirm sizing against the datasheet curves on request.
Code A fits the automatic drain, which expels collected condensate without daily manual attention - useful on lines that run unattended. The same GFR600 body is also orderable with a manual drain (code M) or the differential-pressure default, and with a 5 um element (code W) if finer filtration is needed.
