The AirTAC GFR600C25ANWTK 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 AirTAC GFR600C25ANWTK is a 600-size filter regulator that removes water and particulate from compressed air and holds downstream pressure in one body. This configuration is threaded NPT1 (1 in), carries the 5 um filter element (code W) instead of the 40 um standard element, and drains condensate automatically, so the bowl does not need manual bleeding during a shift. The bowl on the 600 size is aluminium alloy. The regulator is the standard type with a setting range of 0.15-0.9 MPa (20-130 psi) under automatic or differential-pressure draining, against a maximum inlet pressure of 1.0 MPa (145 psi), and the operating temperature range is -5 to 70 C (non-freezing). A reverse/check valve is fitted (code K), a mounting bracket is included, and no gauge is supplied with this code.
This is a genuine AirTAC part from the GFR filter-regulator family, which spans the 200, 300, 400 and 600 sizes with port options from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drain, 40 um or 5 um filtration, gauge and thread options, and an optional low-pressure regulator type. Flow figures for this family are published as curves rather than a single rated number, so ask us to confirm the datasheet and sizing for your application on request.

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.

Mounted at the drop from a plant air header, the unit cleans water and debris out of the supply and holds a steady set pressure to the line's pneumatic cylinders and sealers, with automatic drain keeping the bowl clear through unattended shifts.
On a machining centre's pneumatic clamps and tool-change actuators, the 5 um element protects directional valves and cylinders from fine particulate while the regulator holds the consistent pressure the clamping sequence depends on.
Feeding the pushers, stoppers and lift gates on a bottling conveyor, the filter regulator keeps moisture and scale out of the actuators and pins the operating pressure so product handling stays repeatable from start-up to washdown.
Step up or down through the 200/300/400/600 sizes and their matching ports (1/8 in to 1 in) to suit the pipe run and the flow your line needs; the 600 size with a 1 in NPT port is the large-flow end of the range. Choose the drain to match the site: automatic drain (this code) for unattended duty, manual drain where someone walks the line, or the differential-pressure default. Pick 40 um for general upstream protection or 5 um (this code) where downstream valves and actuators need finer filtration. A gauge is optional on GFR units and is not fitted on this code, so add one if the setpoint must be visible at the unit; gauge scales are available in MPa, psi or bar. Thread is PT as the AirTAC standard, with G (BSPP) and NPT (this code) as order options; a bracket is included, and a reverse/check valve can be specified to hold downstream pressure. Flow for this family is published as curves, not a single rating, so 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 family as curves rather than a single rated figure, so we do not quote a l/min, m3/h or SCFM number. Send us your application details and we will confirm the flow curve and datasheet figures for this 600-size, 1 in NPT unit on request, so you can size it against your demand before ordering.
The W in the code selects the 5 um element in place of the 40 um standard, which suits downstream valves and actuators that need finer filtration. The A selects the automatic drain, so condensate is discharged without manual bleeding; the alternative is a manual drain or the differential-pressure default. Both choices are order options across the GFR range, so you can match them to your site.
