The AirTAC GFR600C25AJF2WTK 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 GFR600C25AJF2WTK is an AirTAC GFR-series filter regulator: one body that removes water and particulate from compressed air and holds downstream pressure steady. This size 600 unit is built for 1 in NPT piping, carries a 5 um filter element (the finer of the two catalogue grades), an automatic drain that ejects collected condensate without manual attention, and an embedded square gauge reading in psi. A reverse/check valve is fitted, the regulator is the standard type adjusting across 0.15-0.9 MPa (20-130 psi), and this configuration omits the mounting bracket. On size 600 the bowl is aluminium alloy.
This is a genuine AirTAC part. The G-series filter regulator range spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, a choice of drain type, 40 um or 5 um filtration, gauge style and scale, and PT, G or NPT threads. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so ask us to confirm sizing 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.

A 1 in filter regulator feeding a paint line's main air drop keeps water and fine particulate out of spray air while holding a steady regulator setting for the guns and booths.
On a bottling or canning line, the unit conditions the header air that drives cylinder and gripper manifolds, with the automatic drain handling condensate on a line that runs unattended across shifts.
Feeding a CNC machine tool's pneumatic manifold, the regulator holds a fixed supply pressure for clamps and tool-change cylinders while the 5 um element protects downstream valves.
Size and port step up with flow demand: 200, 300, 400 and 600, with ports from 1/8 in to 1 in; this unit sits at the top of the range on 1 in NPT. Drain choice matters: automatic drains suit unattended installations, manual drains need operator rounds, and the differential-pressure default opens only at a set pressure drop. Filter grade is 40 um standard or 5 um (code W) for finer protection; this unit carries 5 um. Gauge scale can be MPa, psi or bar, and thread can be PT, G or NPT to order. Flow is published as curves, not a single rated figure, so send us your flow and pressure requirements and we will confirm sizing from 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 GFR600 flow as curves rather than a single rated figure, so we do not quote one number here. Send us your required flow and working pressure and we will confirm the sizing from the datasheet on request.
On size 600 the bowl is aluminium alloy (the smaller 200-400 sizes use polycarbonate), and the A code fits an automatic drain that ejects condensate without manual attention. The W code selects the finer 5 um element instead of the 40 um standard.
