The AirTAC GFR600C25F1WTK 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 GFR600C25F1WTK is a filter regulator: one body that removes water and particulate from compressed air and holds the downstream pressure at your setpoint. This size 600 unit carries a 1 in NPT port, the 5 um filter element (the finer of the two available grades), a differential-pressure drain, an aluminium alloy bowl, an embedded square gauge scaled in MPa, and a fitted reverse (check) valve; a mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulator setting range with differential-pressure drain is 0.15-0.9 MPa (20-130 psi), and the operating temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR series spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, plus options such as manual or automatic drains, the 40 um standard element, psi or bar gauge scales, G (BSPP) or NPT threads in place of the PT standard, and an external round gauge. Flow is published as curves rather than a single rating, so ask us to confirm the figures from the datasheet 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.

At a 1 in main air drop feeding a paint line, the unit strips water and particulate ahead of spray equipment and holds a steady regulated pressure at the guns, with the 5 um element guarding against finish defects.
On a cartoning or palletising conveyor run with many pneumatic cylinders, the filter regulator cleans the plant air and keeps actuator pressure consistent so indexing and clamping motions stay repeatable.
On a machining centre where fixtures and tool-change actuators run on shop air, the unit removes condensate and chips-laden particulate and sets the clamping pressure the fixture designer specified.
Start with size and port: 200, 300, 400 and 600 step up in port and flow capacity, and this unit sits at the top of the range with a 1 in NPT port. Drain choice is a real decision: differential-pressure (the default, fitted here) drains as pressure drops across the element, automatic (code A) drains continuously, and manual (code M) drains only when operated. Filter grade is 40 um standard or 5 um with code W - this unit carries the 5 um element for finer protection of downstream equipment. The embedded square gauge is standard with MPa, psi or bar scales, and an external round gauge is optional. Thread is PT as the catalogue standard, with G (BSPP) and NPT as orderable options - this unit is specified with NPT. A mounting bracket is included. 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 GFR flow as curves rather than a single rated figure, so there is no one l/min or SCFM number we can honestly quote. Tell us your application and we will confirm the relevant flow figures from the datasheet on request before you order.
The GFR series filters at 40 um as standard, with 5 um available as the W option, and the W in this model code means the finer 5 um element is fitted. Choose 5 um where downstream valves, cylinders or instruments need finer protection; the rest of the configuration, including the differential-pressure drain and square MPa gauge, works the same way.
