The AirTAC GFR60025ALC3TK 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 GFR60025ALC3TK is an AirTAC GFR600 filter regulator: filtration and pressure regulation combined in one body. It removes water and particulate from compressed air at the 40 um standard grade, then holds a set downstream pressure, and it is the low-pressure type for circuits that run at reduced supply pressure. This configuration is a size 600 unit with a 1 in NPT port, an automatic drain that expels collected condensate without manual attention, an aluminium alloy bowl, a reverse/check valve fitted, and a round pressure gauge reading in bar; a mounting bracket is included.
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 options include manual or differential-pressure drains, a 5 um filter grade (code W), square or round gauges with MPa, psi or bar scales, G or NPT threads in place of the PT standard, and bracket choices. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.
| 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). |
| 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.

Feeds filtered, pressure-controlled air to a spray booth supply drop at the low pressures paint equipment expects, with the automatic drain keeping condensate out of the finish.
Sits at the head of a packaging conveyor's air run, cleaning the supply and holding a steady pressure for the flap-fold and taping cylinders along the line.
Conditions the air feeding pneumatic quarter-turn valve actuators on a plant skid, where the low-pressure type regulation and a bar-reading gauge suit the actuator's control loop.
Start with the port and size: this unit is size 600 with a 1 in NPT port, the largest step in the GFR range, so match it against the pipe diameter and air demand of the circuit; smaller sizes 200 to 400 step down through 1/8 in to 3/4 in. Choose the drain next: this unit has an automatic drain, which suits points that are hard to reach or run unattended, while manual and differential-pressure drains are available in the family. The 40 um element is the standard grade; specify the W code if the application needs 5 um filtration. The gauge here is a round type reading in bar; embedded square gauges and MPa or psi scales are the other catalogue choices. This is the low-pressure type, so confirm the control range suits your circuit before ordering. Thread is NPT here; PT is the standard and G (BSPP) is also an order option. A bracket is included.
Flow for this family is published as curves, not a single rated number, so send us your application details and we will confirm the datasheet figures and sizing 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, not as a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the datasheet flow curves and check the sizing for your line before you order.
The A in the code selects the automatic drain, which expels collected condensate on its own instead of waiting for someone to open a manual drain - useful on unattended or hard-to-reach installations. The bowl is aluminium alloy because this is a size 600 unit; sizes 200 to 400 in the family use polycarbonate bowls.
