The AirTAC GFR600C25JF3WTK 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 GFR600C25JF3WTK is a size-600 filter regulator: it removes water and particulate from compressed air and holds downstream pressure at your setpoint in one body. This configuration is built for a 1 in NPT line, carries the 5 um filter element (code W) instead of the 40 um standard element, and drains condensate by differential pressure, so the bowl purges as the pressure drop across the element builds. The standard regulator covers a 0.15-0.9 MPa (20-130 psi) setting range, an embedded square gauge reading in bar is fitted, and a reverse/check valve (code K) holds the downstream setting if upstream pressure is lost. No mounting bracket is included (code J), and the size-600 bowl is aluminium alloy. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part from the GFR family, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in up to 1 in, a choice of differential-pressure, automatic or manual drain, 40 um or 5 um filtration, gauge or no gauge, and PT, G or NPT threads. Flow for this unit is published as curves rather than a single rating, so ask us and we will confirm the datasheet figures for your application before you order.

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.

At each spray-booth drop, the GFR600C25JF3WTK strips water and fine particles from the plant air supply and holds a steady regulator setting to the guns, with the check valve keeping the setting stable if feed pressure dips mid-shift.
Feeding the machine tool's pneumatic clamps, tool-change cylinders and air blast circuits, the unit filters the shop air to 5 um and regulates it to the pressure the cell was designed around, draining accumulated condensate automatically by differential pressure.
On a bottling or carton-packing conveyor, the unit conditions and regulates the air driving the diverter and pusher cylinders, so stroke speed stays consistent through the shift and the 1 in NPT connection matches the main header feeding the line.
Step through the decodable choices in order. Size and port: 600 is the largest G-series frame with a 1 in port, so match it to the pipe diameter and the flow your line needs - we can check the published flow curves against your demand before you commit. Drain: this unit uses differential-pressure drainage; choose automatic (code A) if the unit sits where nobody walks past it, or manual (code M) if you want a deliberate purge. Filter grade: this one carries the 5 um element (W); the 40 um standard element suits general plant air where only bulk water and coarse particles matter. Gauge: an embedded square gauge in bar is fitted here, with MPa or psi scales and an external round gauge available as options. Thread: PT is the standard; G (BSPP) and NPT are catalogue options ordered by suffix, and this unit is the NPT version. Bracket: code J means no bracket, so add one if the unit will be wall- or panel-mounted. Because flow is published as curves rather than a single rated figure, send us your application details and we will confirm sizing from 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 GFR600 series as curves, not as a single rated number, so there is no one figure we can honestly quote. Send us your line pressure, set pressure and expected air demand, and we will confirm the flow figures from the datasheet against your application before you order.
W is the filter grade: this unit carries the optional 5 um element instead of the 40 um standard element, for finer removal of particulate from the air stream. K means a reverse/check valve is fitted, so the regulator holds its downstream setting if the upstream supply pressure is lost. Both are standard decodable options on the GFR family, not modifications.
