The AirTAC GFR600C25JC3WTK 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 GFR600C25JC3WTK 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 600-size unit is threaded 1 in NPT, carries a 5 um filter element (code W), and drains collected condensate by differential pressure, so the bowl empties itself as it fills. An external round gauge reading in bar is fitted, a reverse/check valve is built in, and no mounting bracket is supplied. The bowl on this largest 600 frame is aluminium alloy, and the standard regulator adjusts from 0.15-0.9 MPa (20-130 psi) with a maximum inlet pressure of 1.0 MPa (145 psi) at -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family spans 200, 300, 400 and 600 sizes with ports from 1/8 to 1 in, and options that include manual or automatic drains, 40 um or 5 um elements, embedded square or external round gauges with MPa, psi or bar scales, PT, G or NPT threads, a reverse/check valve, and a low-pressure regulator type. 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.

Feeding spray guns and air-assisted applicators on a paint line, where the 5 um element keeps water and grit out of the finish and the regulator holds a steady gun pressure at the booth.
Supplying the pneumatic cylinders and flap-folders on a packaging conveyor; the round bar gauge lets line staff check the set pressure at a glance while the differential-pressure drain keeps condensate away from the valves.
Filtering and regulating air to power clamps and vise actuators on a machining centre, where steady clamp pressure protects part accuracy through a full shift.
Step up to the 600 size with its 1 in NPT port when your line's air demand sits at the top of the GFR range; the 200, 300 and 400 frames step down in port and capacity. This unit pairs a 5 um element with a differential-pressure drain, which empties the bowl automatically, while a manual-drain variant instead widens the regulation range down to 0.05 MPa (7 psi). The fitted round gauge reads in bar; an embedded square gauge and MPa or psi scales are the alternative codes. Thread here is NPT - PT is the standard across the range and G (BSPP) is also orderable, all as specification choices. No bracket is fitted on this code; brackets are optional. Because flow is published as curves rather than a single rating, send us your air demand 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 figure, so we do not quote a number here. Send us your air demand and operating pressure and we will confirm the flow from the datasheet on request.
The W code specifies the 5 um element instead of the 40 um standard, for finer protection of downstream equipment, and the C3 code fits an external round gauge reading in bar. Embedded square gauges and MPa or psi scales are available as alternative codes.
