The AirTAC GFR600C25AJC3WT AirTAC Filter Regulator NPT 1 in 5 um 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 GFR600C25AJC3WT is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and holds downstream pressure in a single body. This 600-size unit has NPT 1 in ports, a 5 um filter element (code W), an automatic drain on the bowl, and an external round pressure gauge reading in bar. The standard regulator gives a 0.15-0.9 MPa (20-130 psi) adjustment range, maximum inlet pressure is 1.0 MPa (145 psi), and the working temperature range is -5 to 70 C, non-freezing. The 600-size bowl is aluminium alloy, and this configuration is built without a mounting bracket or reverse/check valve.
This is a genuine AirTAC part. The GFR family spans 200, 300, 400 and 600 sizes with ports from 1/8 in to 1 in, and catalogue options include manual or differential-pressure drains, the 40 um standard element, embedded square or external round gauges with MPa, psi or bar scales, G (BSPP) or NPT threads in place of the PT standard, and mounting brackets. Flow for this series 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.

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.

Filtering and regulating the air fed to spray booths and paint guns on an automotive trim line, where water carryover and pressure drift both work against finish quality.
Supplying regulated air to pneumatic clamps and vises in a machining cell, holding a stable set point to the fixtures cycle after cycle.
Conditioning the air feeding cylinders and grippers on a cartoning or palletising conveyor, with the automatic drain clearing collected condensate between shifts.
Size the unit by port and flow: the 600 size is the largest in the GFR range, with a 1 in NPT port on this model, and each size step changes both the port and the flow capacity. Drain choice matters: automatic drains condensate without operator attention, manual requires someone to open the drain, and differential-pressure is the catalogue default; this model carries the automatic drain (A). Filter grade is 5 um here (code W) against the 40 um standard. The gauge fitted is the external round type reading in bar; the embedded square gauge and MPa or psi scales are the other catalogue choices. Thread is NPT on this model; PT is the standard thread and G (BSPP) is also available to order. A mounting bracket can be ordered where this no-bracket configuration needs one. 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 rather than a single rated figure, so we do not quote a number here. Send us your flow and pressure requirements and we will confirm the datasheet figures for the GFR600 size against your application.
The 40 um element is the catalogue standard and suits general plant air; the 5 um element (code W on this model) is the finer option for downstream equipment that needs cleaner air. Both are catalogue choices across the GFR family, and this unit is supplied with the 5 um element.
