The AirTAC GFR60025AF2TK 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 GFR60025AF2TK is a GFR-series filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady in one body. This 600-size unit is configured with a 1 in NPT port, automatic drain, 40 um standard filtration, an embedded square gauge reading in psi, a reverse/check valve, and a mounting bracket. The automatic drain ejects collected condensate without anyone having to open the bowl, which suits lines that run unattended.
This is a genuine AirTAC part. The GFR range spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, PT as the standard thread and G or NPT as order options, automatic or manual drains, a 5 um (code W) filter grade, MPa/psi/bar gauge scales, and an optional reverse/check valve. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures 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. Standard type, regulating 0.15 - 0.9 MPa (20 - 130 psi). 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.

| F | Gauge shape: Square. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |

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 impact tools and pneumatic clamps at a 1 in main air drop, where the filter-regulator cleans the supply and holds a steady working pressure for the whole station.
Supplying the cylinder banks that index and divert bottles, with the automatic drain clearing condensate on a line that runs through shifts without an operator at the bowl.
Conditioning shop air ahead of pneumatic tool changers and clamping fixtures, where the reverse/check valve holds the circuit if supply pressure dips.
Size the unit by the flow your line needs: the 600 size with its 1 in port is the largest step in the GFR range, so if your demand sits below what a 1 in line carries, a 300 or 400 unit may be the more economical choice. Drain type is a real decision: automatic (this unit) empties the bowl on its own, manual needs an operator, and differential-pressure draining suits steady continuous demand. Filtration is 40 um standard; choose the 5 um W grade only where downstream equipment demands finer air. The embedded square gauge here reads in psi; MPa and bar scales are available, and an external round gauge is optional. Thread is NPT on this unit (PT is the catalogue standard, G and NPT are order options), the reverse/check valve is fitted, and the bracket is included. Because flow is published as curves rather than a single rating, send us your application details 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, not as a single rated number, so we do not quote one here. Send us your application details and we will confirm the flow figures from the datasheet so you can size the unit correctly before ordering.
The A in the code means the bowl drains itself: condensate is ejected automatically instead of waiting for an operator. If your line runs steadily rather than unattended, the same GFR600 size is also available with a manual drain or the default differential-pressure drain - just ask for the equivalent code.
