The AirTAC GFR600C25AF3WTK 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 GFR600C25AF3WTK is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration carries a 1 in NPT port, a 5 um filter element (the finer of the two published grades), an automatic drain that vents collected condensate without manual attention, and an embedded square gauge reading in bar. A reverse/check valve is fitted, and the mounting bracket is included. Maximum working (inlet) pressure is 1.0 MPa (145 psi), the standard regulator adjustment range with automatic drain is 0.15-0.9 MPa (20-130 psi), and the operating temperature is -5 to 70 C (non-freezing). At size 600 the drain bowl is aluminium alloy.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drain, 40 um standard or 5 um (W) filtration, square or round gauges with MPa, psi or bar scales, PT (standard), G or NPT threads, and an optional reverse/check valve. Flow is published as curves rather than a single rated figure, 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.

Cleaned and pressure-settled air at each paint-line drop: the 5 um element and automatic drain keep water and particulate out of the supply feeding the spray area, with the gauge showing set pressure at a glance.
A regulated air supply for the cylinders and air bells on a carton-forming and sealing conveyor, where the automatic drain handles condensate on a line that runs unattended through shifts.
Filtered, regulated air feeding the pneumatic valve manifold on a bottle-filling and capping machine, with the check valve holding the downstream circuit if supply pressure dips.
Start with the port step: this unit is the size-600 frame with a 1 in NPT connection, the largest in the GFR range - match it to your line size and the flow curve, not to a single rated number. Choose the drain to suit access: automatic (this unit) suits unmanned or hard-to-reach installations, manual suits supervised points, and differential-pressure is the catalogue default. Choose the element grade: 40 um is standard for general plant air; the 5 um (W) grade fitted here suits finer downstream needs. Gauge scale is selectable (MPa, psi or bar) and this unit carries the embedded square gauge in bar; PT is the standard thread with G and NPT as order options, and the bracket is included.
Because flow is published as curves rather than one rating, send us your application details 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 GFR series as curves rather than a single rated figure, so we do not quote one number. Tell us your application and we will confirm the flow and datasheet figures for this 1 in NPT size-600 unit on request before you order.
This unit carries code A, the automatic drain, which discharges collected condensate without anyone opening the bowl - useful for unattended or hard-to-reach installations. The GFR family is also available with manual drain or the differential-pressure drain (the catalogue default); the adjustment range differs slightly by drain type, with manual-drain versions able to regulate down to 0.05 MPa.
