The AirTAC GFR600C25AF1TK 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 See datasheet ports, a differential-pressure 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 GFR600C25AF1TK is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and holds a regulated downstream pressure in one body. This size 600 unit is fitted with 1 in NPT ports, an automatic drain that ejects collected condensate without manual attention, a 40 um standard filter element, an embedded square pressure gauge with MPa scale, a reverse/check valve, and a mounting bracket. The standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi), with a maximum inlet pressure of 1.0 MPa (145 psi) and an operating temperature of -5 to 70 C (non-freezing).
This is a genuine AirTAC part from the GFR range, which spans sizes 200 to 600 with port options from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drain, a 5 um optional element (code W), gauge scale choices, and G/NPT thread variants. Flow is published by AirTAC 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. 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.

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.

Installed at the 1 in main drop feeding a production hall, it filters water and particulate out of the compressor supply and holds a steady regulated pressure for the whole downstream ring main.
Mounted ahead of the valve manifold on a cartoning or palletising conveyor, it conditions the air driving cylinders and grippers while the check valve holds settings against backflow.
Fitted at the supply point of a spray booth or finishing line, it removes condensate and coarse particulate before the air reaches regulators and equipment downstream, with automatic drain keeping the bowl clear through long shifts.
Size 600 with 1 in NPT ports is the largest step in the GFR range, so start here when the line diameter and the air demand at the point of use point to a 1 in supply. Choose the drain to match access: automatic drain (this unit) suits unattended or high-condensate duty, manual drain suits attended stations, and the differential-pressure default is the catalogue baseline. The 40 um element is standard; specify the W code for 5 um where finer particulate removal is needed. The embedded square gauge reads in MPa; external round gauges and psi/bar scales are options. Thread is NPT here, with G (BSPP) orderable; PT is the catalogue standard. A bracket is included, and the K code adds a reverse/check valve.
Flow for this series is published as curves, not a single rated number, so we cannot quote a rated flow figure. Send us your application's air demand and line 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. Without the K option, air cannot flow back 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 state a rated flow, Cv or SCFM number. Tell us your air demand and line conditions and we will confirm the sizing from the datasheet on request before you order.
The A in the code sets the automatic drain, which ejects collected condensate without manual attention - useful where the unit is mounted in a less accessible spot. The K adds a reverse/check valve, and the F1 sets the embedded square gauge with an MPa scale. All of these are decode choices you can vary when ordering.
