The AirTAC GFR600C25C2WK AirTAC Filter Regulator PT1 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 GFR600C25C2WK is an AirTAC GFR600 filter regulator: one body that removes water and particulate from compressed air and then regulates downstream pressure. This configuration is built around a 1 in PT port, so it sits directly in a 1 in main air line. It carries the 5 um filter element (code W) for finer filtration than the standard 40 um grade, a differential-pressure drain that bleeds collected condensate automatically whenever the pressure differential across the element is high enough, a round external gauge reading in psi, and a built-in check valve (code K) that holds downstream pressure when the upstream supply is lost. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), and the unit handles a maximum inlet pressure of 1.0 MPa (145 psi) at temperatures from -5 to 70 C (non-freezing). At size 600 the bowl is aluminium alloy, and a mounting bracket is included.
This is a genuine AirTAC part. The GFR family is published in sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drains, 40 um or 5 um filter grades, square or round gauges with MPa, psi or bar scales, and PT, G or NPT threads. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

Dropping from a plant ring main into a 1 in branch that feeds a hall of case packers and wrap stations: the unit strips water and fine particulate from the line and holds a set downstream pressure for the actuators on the machines.
Feeding a manifold that supplies pneumatic grippers and clamps on a robot cell: clean, regulated air protects the valve islands, and the built-in check valve holds the circuit's pressure if the upstream supply drops.
Supplying the air knives, diverters and stop gates along a bottling or carton conveyor: the 5 um element keeps fine contamination out of the nozzles and cylinders while the regulator sets the pressure the line was designed around.
Start with the port and size: 600 is the largest step in the GFR range and this unit takes a 1 in PT connection, so match it to a 1 in main line and to the flow your line actually needs. Next choose the drain: this unit uses the differential-pressure drain (the default), while automatic and manual drains are orderable alternatives on the same family. The filter grade here is 5 um (code W); if your application tolerates coarser protection, the standard 40 um element is the default choice. The gauge on this configuration is an external round gauge scaled in psi; embedded square gauges and MPa or bar scales are the other catalogue options. Thread is PT as standard, with G (BSPP) and NPT available as order options, and a mounting bracket is included with this unit.
One honest note on sizing: AirTAC publishes flow for this series as curves, not as a single rated number, so we do not quote a flow figure here. Send us your application details and we will confirm the datasheet and check the sizing against your required flow 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 state a flow number for this unit. Tell us your line pressure, set pressure and the flow your application needs, and we will confirm the datasheet curve and check the sizing with you before you order.
Both are decode choices in the model code. The W in GFR600C25C2WK selects the 5 um filter grade instead of the standard 40 um element, for finer water and particulate removal. The K selects a built-in reverse/check valve, which holds downstream pressure when the upstream supply is interrupted. The drain is the differential-pressure type (the default), and the gauge is an external round gauge scaled in psi.
