The AirTAC GFR600C25AF1WT AirTAC Filter Regulator NPT1 (1 in) 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 GFR600C25AF1WT is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This 600-size unit is threaded NPT1 (1 in), carries the 5 um filter element (the fine grade; 40 um is the standard option), an automatic drain, and an embedded square gauge scaled in MPa. The aluminium alloy bowl suits the largest frame in the range, the standard regulator covers 0.15-0.9 MPa (20-130 psi), maximum inlet pressure is 1.0 MPa (145 psi), and the working temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and can be ordered with manual or differential-pressure drains, the 40 um element, alternative gauge scales (psi or bar), G (BSPP) or PT threads, and with or without the mounting bracket. 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.

Filtered and regulated air for the tool changer, clamps and pneumatic valves on a CNC machining center, with the 5 um element protecting sensitive valve internals.
Regulated air to the stoppers, pushers and lift cylinders along a bottling line, with the automatic drain coping with condensate during continuous shifts.
A point-of-use filter regulator at assembly-line air drops, giving operators a stable, gauge-monitored supply and an aluminium alloy bowl suited to the 600-size frame.
Size and port step up from 200 to 600; choose the 600 / NPT1 frame when your line's flow demand and 1 in piping call for the largest GFR frame - we will confirm the flow curve against your requirement before you order. Drain choice is differential-pressure (default), automatic (fitted here) or manual; automatic suits unattended installations. Filter grade is 40 um standard or 5 um with code W, as on this unit. Gauges are the embedded square type with MPa, psi or bar scales, and an external round gauge is optional. Thread is PT as standard, with G (BSPP) and NPT as orderable options; the mounting bracket is included. Because flow is published as curves, not a single rating, ask us to confirm sizing against the 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 we do not quote a number here. Send us your application details and we will confirm the datasheet flow curve and sizing for this 600-size, NPT1 unit on request.
The 40 um element is the standard grade for general air preparation; the 5 um element (code W, fitted on this unit) is the finer option for downstream equipment that is more sensitive to particulate. Both are catalogue options on GFR filter regulators, and the automatic drain handles condensate removal either way.
