The AirTAC GFR600C25C2WGK AirTAC Filter Regulator, G1 (1 in), 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 AirTAC GFR600C25C2WGK is a size-600 filter regulator: water and particulate removal plus downstream pressure regulation in a single body. This configuration is built for a G1 (1 in) port with G thread, filters to 5 um for cleaner air than the standard 40 um element, and drains condensate by differential pressure, so the bowl empties itself whenever the pressure differential across the element is high enough. The standard regulator covers 0.15-0.9 MPa (20-130 psi), a round external gauge scaled in psi is fitted for setting, and a reverse/check valve holds downstream pressure if the upstream supply drops. At size 600 the bowl is aluminium alloy. Max inlet pressure is 1.0 MPa (145 psi); operating temperature is -5 to 70 C (non-freezing).
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 or 5 um filtration, gauge style and scale, and a reverse/check valve option. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures for your application before ordering.

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.

Drops from a 1 in plant air main feeding a packaging line: the 5 um element keeps water and fine dirt out of the line's valves and cylinders, while the regulator sets a stable working pressure for the whole drop and the check valve holds it during upstream dips.
A single point of treatment for the air feeding conveyor gate and diverter cylinders: filtration and regulation in one body saves a drop-out space, the psi gauge lets maintenance set and verify the pressure the actuators were designed for, and the differential drain keeps condensate moving without daily attention.
A wall-mounted supply point for 1 in air tools such as impact wrenches and large grinders in a maintenance bay: the 5 um grade protects the tool's air motor, the regulator lets the operator dial in working pressure, and the included bracket secures the unit beside the drop.
Step up through sizes 200, 300, 400 and 600 as your port size and air demand grow; this unit is the top of the range at G1 (1 in). Choose the drain to suit access: differential-pressure (this unit) needs no attention, automatic drains continuously, and manual suits attended installations. Pick 5 um filtration (this unit) where downstream equipment needs cleaner air than the 40 um standard. Select the gauge scale - MPa, psi or bar - and whether you want the embedded square gauge or the external round gauge fitted here. Thread is G on this model; PT is the standard with G and NPT as order options. A bracket is included for mounting, and the K code adds the reverse/check valve. Because flow is published as curves rather than a single rated figure, 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, not as a single rated figure, so we do not quote a number here. Send us your line pressure, working pressure and expected air demand, and we will confirm the flow from the datasheet and check the sizing against your application before you order.
The W code in the model selects the 5 um element in place of the 40 um standard. It removes finer particulate for downstream valves, cylinders and tools that need cleaner air. If your application does not require the finer grade, the same size is available with the standard 40 um element.
