The AirTAC GFR600C25AC3WT 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 AirTAC GFR600C25AC3WT is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration is built around a 1 in NPT port, carries the fine 5 um filter element (the W grade, tighter than the 40 um standard), and drains condensate automatically, so the bowl does not depend on someone opening a manual drain. The regulator is the standard type with a 0.15-0.9 MPa (20-130 psi) adjustment range, and a round gauge on a bar scale is fitted so the set pressure is visible at the unit. At size 600 the bowl is aluminium alloy, and a mounting bracket is included.
This is a genuine AirTAC part from the GFR filter-regulator line, 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, 40 um or 5 um filtration, gauge and scale options, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures for your application before ordering.

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.

Feeds the main air drop of a CNC machining cell, filtering condensed water and swarf-carrying particulate out of the shop supply and holding a steady regulated pressure to the machine's pneumatic valves and clamps.
Conditions the air feeding a packaging or bottling line's conveyor stops, diverters and case-packing cylinders, where the 5 um element protects closely toleranced valve spools and the automatic drain copes with continuous running.
Serves the air supply to an industrial paint or coating booth, where clean, dry, pressure-stable air is needed for atomizing and air-assisted spray equipment and pressure drift would show up directly in finish quality.
Size 600 with a 1 in port is the largest step in the GFR range, so start there when the line feeds high-consumption downstream equipment; smaller 200/300/400 sizes cover lighter duty at smaller ports. This unit already carries the fine 5 um element - choose it when downstream valves, cylinders or instruments need cleaner air than the 40 um standard, and note that automatic drain suits unattended or hard-to-reach installations, while manual or differential-pressure drain variants exist for other service styles. The fitted round gauge reads in bar; square embedded gauges and MPa or psi scales are the other catalogue options. Thread is NPT here, with PT (standard) and G available to order, and a bracket is included for panel or surface mounting. 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. 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 GFR600 as curves, not as a single rated number, so we do not quote a figure that could mislead your sizing. Send us your line pressure, set pressure and the equipment you are feeding, and we will confirm the relevant datasheet flow figures for this 1 in NPT unit on request.
The A in the code means the bowl drains condensate automatically, which suits installations that run unattended or sit where the bowl is awkward to reach. Differential-pressure drain (the default) and manual drain versions are available in the same GFR600 family if your maintenance routine prefers them - just ask for the matching model code.
