The AirTAC GFR600C25AJF2TK AirTAC Filter Regulator NPT1 40 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 AirTAC GFR600C25AJF2TK is a size-600 filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady, in one body. This configuration has a 1 in NPT port, an automatic drain that ejects collected condensate without anyone opening it, the standard 40 um filter element, an embedded square gauge reading in psi, and a built-in reverse (check) valve (code K). No mounting bracket is fitted (code J).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, PT as the standard thread and G (BSPP) or NPT as order options, manual or automatic drains, a 5 um element option (code W), and gauge or no-gauge variants. Maximum inlet pressure is 1.0 MPa (145 psi), the regulating range is 0.15-0.9 MPa (20-130 psi), and the operating temperature is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, 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.

Fitted at the 1 in drop from the receiver tank, it strips water and scale from the plant air supply and holds a steady header pressure for the whole ring main, with the automatic drain handling condensate in an unattended room.
Feeding clamps, tool changers and air blow-off on a machining centre, it keeps fixture and actuator pressure stable at the set point while the 40 um element stops pipe-scale reaching the valves.
On a case-packer or palletiser line with large-bore cylinders, the 1 in port serves the high-demand main, the check valve holds the downstream circuit if supply dips, and the psi gauge lets technicians set and verify line pressure.
Size 600 with a 1 in port is the largest step in the GFR range - choose it when the line diameter and expected flow demand the biggest port, and step down to 300 or 400 for smaller branches. Drain choice: automatic (this unit) suits points that are hard to reach; manual suits attended stations; the differential-pressure default drains on a pressure drop. Filter grade is the 40 um standard element; specify W for the 5 um option where finer filtration is needed. The square gauge on this unit reads psi; MPa and bar scales are also available, and an external round gauge is optional. The K code means a reverse/check valve is fitted, and J means no mounting bracket. Thread is NPT here; PT is the standard and G (BSPP) is orderable. Flow is published as curves, not 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 number here. Tell us your line pressure and the flow your equipment needs, and we will confirm the sizing from the datasheet on request before you order.
The automatic drain ejects the water and contaminants collected in the aluminium alloy bowl on its own, so the unit suits positions that are not checked daily; manual-drain and differential-pressure-drain versions are available if you prefer. The K code means a reverse (check) valve is fitted, which holds the downstream circuit if the upstream supply drops.
