The AirTAC GFR600C25F2WTK AirTAC Filter Regulator NPT1 5 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 GFR600C25F2WTK is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and holds downstream pressure in a single body. This size-600 unit has a 1 in NPT port, a 5 um filter element (code W), a differential-pressure drain, an embedded square gauge reading in psi, and a reverse/check valve; the mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi), the regulator adjusts from 0.15-0.9 MPa (20-130 psi), and the working temperature range is -5 to 70 C (non-freezing). The bowl on size-600 units 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, and options for manual or automatic drains, 40 um or 5 um elements, gauge scales in MPa, psi or bar, and G, NPT or PT threads. Flow is published as curves rather than a single rating, so ask us to confirm 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 clean, pressure-stabilised air to spray guns and booths on a paint line, where the 5 um element helps keep water and particulate out of the finish and the regulator holds a set point for consistent atomisation.
Supplying filtered, regulated air to the pneumatic cylinders that push, clamp and divert cartons on a packaging conveyor, with the check valve helping hold the downstream circuit if upstream pressure dips.
Providing conditioned air to pneumatic quarter-turn actuators on process valves at a water treatment plant, where the regulator keeps actuator pressure steady and the 1 in port suits a high-consumption header.
The decodable choices on this family are: size 200/300/400/600 with the matching port (here 600 with 1 in NPT); drain type - differential-pressure (default, as fitted here), automatic (A) or manual (M); filter element 40 um standard or 5 um with code W (this unit is 5 um); gauge scale MPa, psi or bar, or no gauge with code N; thread PT standard with G and NPT as order options; and bracket included or omitted (J). Note that the regulation range differs by drain type: 0.15-0.9 MPa (20-130 psi) with automatic or differential-pressure drains, 0.05-0.9 MPa (7-130 psi) with a manual drain. Flow is published as curves rather than a single rated figure, so please 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 one number. Tell us your application and required flow and we will confirm the figures from the datasheet on request before you order.
The W in the code specifies the 5 um element; 40 um is the standard grade and carries no code letter. Both grades are catalogue options across the GFR range, so pick the element that suits the sensitivity of your downstream equipment.
