The AirTAC GFR60025ALJC3TK AirTAC Filter Regulator 1 in NPT 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 GFR60025ALJC3TK is a size-600 filter regulator: water and particulate filtration plus pressure regulation combined in a single body, so one component conditions the air and holds your set pressure downstream. This configuration is built around a 1 in NPT port for high-flow main lines, the standard 40 um filter element, and an automatic drain that expels collected condensate from the bowl without anyone opening it. Because it is the size-600 unit, the bowl is aluminium alloy. The regulator is the low-pressure type, an external round gauge with a bar scale is fitted for setpoint monitoring, and a reverse (check) valve is included so downstream pressure is held if the supply side drops. No mounting bracket is supplied with this code.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and can be ordered with manual or differential-pressure drains, a 5 um element (code W), embedded square or external round gauges with MPa, psi or bar scales, and PT, G or NPT threads. Flow figures for this family are published as curves rather than a single rated number, so ask us and we will confirm the datasheet values for your application 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.

|---|---|
| 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). |
| C | Gauge shape: Round. 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.

Feeding pneumatic clamps and workholding fixtures on a machining centre, where the filter stage keeps swarf-laden, wet shop air out of the clamp cylinders and the low-pressure regulator holds a gentle, repeatable clamp force at the gauge setpoint.
Conditioning the main air drop that drives stopper, pusher and gate cylinders along a parcel sorting conveyor, with the automatic drain clearing condensate from a long header run and the check valve holding actuator position if the supply dips.
Supplying the air cylinders that index, fill and cap bottles on a beverage line, where the 40 um element protects the valve seats from particulate and the low-pressure regulation keeps handling motions smooth at reduced line pressure.
Size and port are the first choice: the 600 frame with a 1 in port sits at the top of the GFR range, so match it to your largest main-line flow demand and step down to 300/400 only where the line is smaller. Drain type is a real decision: automatic (this unit) suits unattended duty, manual suits periodic maintenance rounds, and the differential-pressure default drains only when the pressure drop justifies it. Filter grade is 40 um standard or 5 um with code W if downstream valves and cylinders need finer protection. Gauge scale is selectable (MPa, psi or bar) and this code carries the external round gauge in bar. Thread: PT is the standard, with G (BSPP) and NPT as order options - this code is NPT. Bracket is omitted on this code (J), so plan your own mounting. One honest note: AirTAC publishes flow as curves, not a single rating, so send us your application and we will confirm sizing against the datasheet before you order.
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 rather than a single rated figure, so we do not quote a number here. Tell us your application and line conditions and we will confirm the datasheet flow curve and sizing for this 1 in NPT unit on request before you order.
The A in the code selects the automatic drain, which expels collected condensate from the aluminium bowl on its own - useful where the unit is mounted in a hard-to-reach spot or runs unattended. The same GFR600 body can be ordered with a manual drain (code M) for maintenance-round duty, or with the differential-pressure drain (blank) as the default. Drain choice does not change the 40 um filter grade or the 1 in NPT port.
