The AirTAC GFR600C25AC1WTK AirTAC Filter Regulator NPT1 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 GFR600C25AC1WTK is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady in a single body. This size 600 unit is specified with a 1 in NPT port, a 5 um filter element (code W), an automatic drain that ejects collected condensate without manual attention, a round MPa gauge, and a reverse/check valve. With automatic drain, the regulator adjustment range is 0.15-0.9 MPa (20-130 psi), and maximum inlet pressure is 1.0 MPa (145 psi). The bowl on this largest frame is aluminium alloy, and operating temperature is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drain, 40 um standard or 5 um (W) filtration, embedded square or external round gauges with MPa/psi/bar scales, PT, G or NPT threads, and bracket options. Flow is published as curves rather than a single rating, so we confirm datasheet figures 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.

Clean, pressure-steady air for pneumatic clamps, tool-change cylinders and chip-clearing blasts on a machining centre, with the 5 um element protecting fine control valves and the check valve holding settings through supply dips.
A filtered, regulated drop feeding fillers, cappers and labeler actuators on a beverage line, where the automatic drain handles condensate between shifts without an operator opening the bowl.
Stable pressure for diverter gates, stoppers and pusher cylinders on a high-cycle packaging conveyor, keeping actuator timing consistent as the main header pressure wanders.
Step up through sizes 200, 300, 400 and 600 against the flow your line needs - this size 600 with a 1 in port is the largest frame, so it suits high-consumption headers and main-line drop regulation. Choose the drain to match attendance on site: automatic (as here) for unattended duty, manual where an operator drains regularly, or the differential-pressure default. Pick 40 um for general protection or 5 um (W, as here) where downstream valves and instruments need finer filtration. Gauge scale is MPa, psi or bar; thread is PT as standard with G and NPT as orderable options - this unit is NPT. A bracket is included, and the fitted reverse/check valve holds downstream pressure if upstream supply drops. Flow is published as curves, not a single rating, so 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 flow for the GFR series as curves, not as a single rated figure, so we do not quote a number. Tell us your application and we will confirm the flow and sizing from the datasheet on request.
The A in the code means an automatic drain: collected condensate is ejected from the aluminium alloy bowl without anyone opening it, which suits unattended installations. The family also offers manual and differential-pressure drain variants if your site prefers those.
