The AirTAC GFR600C25AJF3WT 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 GFR600C25AJF3WT is a size-600 filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady in a single body. This configuration carries a 1 in NPT port, 5 um filtration (the finer of the two published grades), an automatic drain that bleeds collected condensate without manual attention, an embedded square gauge reading in bar, and no mounting bracket. The standard regulator covers a 0.15-0.9 MPa (20-130 psi) adjustment range, and the aluminium alloy bowl suits the larger 600 frame. Maximum inlet pressure is 1.0 MPa (145 psi), with an operating temperature of -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port options from 1/8 in to 1 in, drain types (differential-pressure, automatic, manual), 40 um or 5 um filtration, gauge scale choices, and PT, G or NPT threads. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing figures for your application on request.

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.

Point-of-use conditioning ahead of the solenoid valves and clamping cylinders on a machining centre, where clean, moisture-reduced air at a held pressure keeps tool-change and workholding sequences repeatable.
Filtered and regulated air feeding the pick-and-place grippers and diverter cylinders on a beverage bottling conveyor, where the 5 um grade helps protect close-tolerance actuator seals from particulate carryover.
Conditioned air for the pneumatic axes and test fixtures on a lab automation skid, where the automatic drain handles condensate in an unattended rig and the bar-scaled gauge gives operators a direct setpoint readout.
Step through the decodable choices in order. Start with size and port: the 600 frame with a 1 in port is the largest step in the GFR range, so match it against the pipe size and the flow your line needs. Choose the drain: automatic (this unit) ejects condensate on its own, manual needs periodic operator attention, and the differential-pressure default drains only when the pressure drop across the element warrants it. Pick the filter grade: 40 um is standard for general plant air, while the 5 um grade fitted here suits finer downstream equipment. Set the gauge scale (MPa, psi or bar - bar here) and the thread: PT is the catalogue standard, with G and NPT as order options such as the NPT on this model. Brackets are optional; this unit ships without one.
One honest note before ordering: AirTAC publishes flow for this series as curves, not as a single rated number, so send us your application details and we will confirm the sizing against the datasheet before you commit.
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 performance curves rather than a single rated figure, so we do not quote one number. Tell us your line pressure, downstream demand and acceptable pressure drop, and we will confirm the sizing against the datasheet on request before you order.
The A in the code sets the automatic drain, which ejects collected condensate without an operator, unlike the manual option or the differential-pressure default that drains only under sufficient pressure drop. The W sets the 5 um element, one grade finer than the 40 um standard, for applications feeding finer downstream equipment.
