The AirTAC GFR600C25C1WTK 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 GFR600C25C1WTK is a size 600 filter regulator: water and particulate filtration plus pressure regulation combined in one body. This configuration is built with a 1 in NPT port, a 5 um filter element (the fine W grade), a differential-pressure drain that bleeds collected condensate automatically as flow passes through, a round pressure gauge with an MPa scale, and a reverse/check valve fitted on the regulated outlet. The size 600 bowl is aluminium alloy, and a mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600, with port options from 1/8 in to 1 in, PT as the standard thread and G or NPT as catalogue options, drain choices of differential-pressure, automatic or manual, 40 um standard or 5 um fine filtration, and gauge or no-gauge variants. 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.

On a CNC machining cell, this unit filters water and swarf-laden particulate out of the shop air and holds a steady regulated pressure to clamps, tool changers and pneumatic actuators, with the check valve holding the downstream setting if the main supply dips.
On a carton packaging conveyor, the 5 um element protects diverter and stopper cylinder valves from condensate and fine dirt, while the regulator sets the pressure the divert mechanism was designed for; the differential drain keeps condensate moving out without an operator visiting the bowl.
On a bottling line, this filter regulator sits ahead of the filler and capper valve banks, removing moisture and particles that would gum the valve spools and regulating the supply to the pressure the machine builder specified, with the MPa gauge giving the line technician a direct reading at the setpoint.
Step up through the GFR sizes (200, 300, 400, 600) until the port and flow capacity match your line; this 600 unit takes a 1 in connection for the largest supply runs in the family. Choose the drain to suit access: differential-pressure (this unit, no operator input), automatic, or manual where you want positive control. Pick the element grade: 40 um standard for general plant air, 5 um (W, as fitted here) for finer protection. Gauges are available with MPa, psi or bar scales, in embedded square or external round form, and threads come as PT standard or G/NPT to order; brackets are optional on request.
One honest note before you order: AirTAC publishes filter-regulator flow as curves, not as a single rated figure, so send us your flow and pressure requirements and we will confirm the correct size against the datasheet before you commit.
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 filter-regulator flow as performance curves rather than a single rated number, so there is no one l/min or SCFM figure we can honestly quote. Send us your operating pressure and required flow and we will confirm the sizing against the datasheet curves before you order.
The W in the code GFR600C25C1WTK selects the 5 um fine filtration grade; the catalogue standard for GFR units is 40 um. Choose 5 um where downstream valves, instruments or processes are sensitive to finer particles, and 40 um for general plant air. Both grades are available across the GFR size range, and the differential-pressure drain on this unit carries collected condensate out automatically.
