The AirTAC GFR60025ALF3WT AirTAC Filter Regulator NPT1 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 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 GFR60025ALF3WT is an AirTAC GFR-series filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This 600-size unit has a 1 in NPT port, a 5 um filter element (code W), an automatic drain (code A) and an aluminium alloy bowl. It is the low-pressure type (code L) with an embedded square gauge scaled in bar, and a mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing). The L code marks the low-pressure type; its exact adjustment range is not published in the catalogue, so ask us to confirm it against your set pressure.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600, with ports from 1/8 to 1 in, a choice of PT, G or NPT thread, manual, automatic or differential-pressure drains, 40 um or 5 um elements, and gauge or no-gauge variants. Rated flow for this family is published as curves rather than a single figure, so send us your application details and we will confirm the datasheet figures before you order.

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. |
| (blank) | Mounting bracket included. |
| (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. |
| 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.

Spray booths and low-pressure paint circuits on an automotive finishing line need air reduced below shop pressure and stripped of water and grit. This low-pressure GFR with a 5 um element and automatic drain conditions the main feed ahead of the booth.
A 1 in port feeds banks of cylinders on carton-forming and case-packing conveyors. The regulator holds a steady line pressure for consistent stroke timing while the 5 um element and automatic drain keep condensate and particles out of the valve bank.
Filler and capper valve manifolds on a bottling line demand clean, regulated air at the manifold header. This unit filters to 5 um and regulates the header pressure, with the automatic drain and aluminium bowl handling condensate in wet compressor rooms.
Step up or down through the 200/300/400/600 sizes to match the port and flow your line needs - this 600 model carries a 1 in NPT port, the largest in the range. Choose the drain to suit maintenance: automatic (this unit, code A) discharges condensate without attention, manual (M) on demand, and differential-pressure (blank) is the default. Pick the 5 um element (W) when downstream valves or instruments need finer filtration than the 40 um standard. The square gauge here reads in bar; MPa (1) and psi (2) scales are alternatives, and an external round gauge is optional. Thread is NPT on this code; PT is the standard and G (BSPP) is orderable. A bracket is included. 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 GFR-series flow as curves rather than a single rated figure, so we do not quote a number. Send us your line pressure, set pressure and air consumption and we will confirm the datasheet flow curve for this 1 in NPT, 5 um, automatic-drain unit on request.
A is the automatic drain: condensate is discharged from the aluminium bowl without manual attention. The catalogue also lists manual drain (M) and the differential-pressure drain (blank) as the default, so the GFR600-25 can be ordered with any of the three.
