The AirTAC GFR600C25C2WT AirTAC Filter Regulator NPT1 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 GFR600C25C2WT is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and holds downstream pressure at a set point, in a single body. This size-600 unit carries a 1 in NPT port, the 5 um filter element (code W), a differential-pressure drain, a round pressure gauge reading in psi, and an aluminium alloy bowl. The standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi), with a maximum inlet pressure of 1.0 MPa (145 psi) at -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 in to 1 in, a choice of 40 um standard or 5 um filtration, differential-pressure, automatic or manual drains, embedded square or external round gauges in MPa, psi or bar scales, and PT, G or NPT threads. 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.

Feeding the valve manifold and gripper circuit of a welding robot cell, where filtered air and a steady regulated set point keep the clamps and tooling acting consistently through the shift.
Supplying the cylinder-driven capping, filling and ejection stations on a bottling line, with water and particulate stripped from the shop air before it reaches the directional valves.
Providing regulated air to the tool-change clamp and chip-door circuits of a CNC machining centre, protecting the valves from condensation carryover on a high-demand 1 in main.
Size and port set the air-handling capacity: this is the largest GFR size (600) with a 1 in port, so step down to sizes 200, 300 or 400 with smaller ports when the line needs less air. Drain choice matters in service: the differential-pressure drain fitted here bleeds the bowl automatically as air passes, an automatic drain empties on its own, and a manual drain needs someone to open it - match this to how often the machine is attended. Filtration on this unit is the 5 um grade (code W); the 40 um standard grade suits applications with lighter air-quality demands. The round gauge fitted here reads in psi; embedded square gauges and MPa or bar scales are the other catalogue options. Thread is NPT on this model; PT is the standard thread and G is also available to order. A mounting bracket is included.
Flow for the GFR series is published as curves, not a single rated figure, so 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 line conditions and we will confirm the datasheet curve and correct sizing on request before you order.
The W code on this unit specifies the 5 um element; a blank in that position is the 40 um standard grade. Both grades are catalogue options across the GFR family, so choose 5 um where downstream equipment needs finer filtration and 40 um where it does not.
