The AirTAC GFR600C25AF2WT 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 AirTAC GFR600C25AF2WT is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This 600-size unit is fitted with a 1 in NPT port, a 5 um filter element (the finer W grade, versus the 40 um standard), an automatic drain that expels collected condensate without manual attention, and an embedded square gauge reading in psi. The metal bowl on this 600 size is aluminium alloy. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulator adjusts from 0.15-0.9 MPa (20-130 psi), and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR filter-regulator family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and is offered with a choice of drain type, filter grade, gauge style and scale, thread (PT standard; G and NPT as order options), and bracket. Flow figures for this series are published as curves rather than a single rating, so ask us to confirm the datasheet and sizing 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 on the 1 in main air line feeding a CNC machining center, it strips water and swarf-carrying particles from the shop air and holds a steady regulated pressure for the machine's tool-clamp and pallet-change circuits.
Mounted where the plant air drops to a high-speed packaging conveyor, it delivers cleaned, regulated air to the carton-forming and case-sealing cylinders, with the automatic drain handling condensate on a line that runs unattended.
Fitted at the service drops of a truck and trailer maintenance shop, it conditions the shop compressor supply before it reaches impact wrenches, tire cages and lift controls, with the psi gauge giving technicians a visible set pressure.
Size the unit by the port and flow step: 600 is the largest G-series size, and here it carries a 1 in NPT port, so match it to the main air line feeding your equipment. Choose the drain to suit access: this unit has an automatic drain, which suits installations that are not checked daily; manual and differential-pressure drains are the alternatives in the family. The 5 um element (code W) is the finer choice over the 40 um standard where downstream valves and instruments need cleaner air. The square gauge is fitted here with a psi scale; MPa and bar scales and an external round gauge are the other gauge options. PT is the standard thread, with G (BSPP) and NPT as order options, and a mounting bracket is included. Because flow for this series is published as curves rather than a single rating, 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 rather than a single rated figure, so we do not quote a rated flow number. Tell us your application and line conditions and we will confirm the flow and sizing from the datasheet on request.
The W code in GFR600C25AF2WT selects the optional 5 um filter grade, which is finer than the 40 um standard element. It suits downstream valves, cylinders and instruments that need cleaner air. The automatic drain (code A) then removes the collected condensate without manual intervention.
