The AirTAC GFR60025JF1WTK AirTAC Filter Regulator 1 in NPT is a genuine G-series filter regulator: water separation, 5 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has PT1" 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 GFR60025JF1WTK is an AirTAC GFR600 filter regulator: one body that removes water and particulate from compressed air and holds downstream pressure steady. This size 600 unit is supplied with a 1 in NPT port, a 5 um filter element (the finer W grade, versus the standard 40 um), a differential-pressure drain that bleeds condensate automatically as flow passes through, an embedded square pressure gauge scaled in MPa, and a built-in reverse/check valve that holds downstream pressure when the upstream supply is lost. The aluminium alloy bowl suits this large frame, and the standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi). Maximum 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 ports from 1/8 in to 1 in, and can be ordered with manual or automatic drains, a 40 um or 5 um element, square or round gauges scaled in MPa, psi or bar, a reverse/check valve, 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 sizing and 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.

Installed at the 1 in distribution drop feeding a factory floor, it cleans the compressed air and holds a stable header pressure for every downstream branch circuit.
Mounted ahead of the valve manifold on a bottling or cartoning conveyor line, it delivers filtered, regulated air to the cylinders and grippers running the packaging cycle.
Fitted at the air inlet of a CNC or automated machining cell, its 5 um element and check valve protect clamps and tool-change actuators from water, chips of contamination and supply loss.
Size 600 with a 1 in NPT port is the largest GFR frame, so step up to it when your line's air demand calls for the biggest port in the family, and step down to 300/400 when it does not. This unit carries the 5 um W-grade element: choose it where downstream valves and instruments want finer filtration than the standard 40 um, noting that a finer element loads faster and needs earlier drain attention. The differential-pressure drain is the fit-and-forget choice; specify automatic (A) or manual (M) codes where you want a different drain behaviour. The square gauge is fitted and scaled in MPa; round gauges and psi or bar scales are orderable alternatives. The K code adds a reverse/check valve, useful where a cylinder or process must not lose pressure on supply failure. Note this J-code unit ships without a mounting bracket, and the thread here is NPT - PT is the catalogue standard, with G and NPT as orderable options.
Because flow is published as curves rather than a single rated number, we cannot quote you one figure here. Send us your application's flow and pressure requirements 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. The reflux valve permits reverse flow 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. Tell us your required flow and working pressure and we will confirm sizing against the datasheet on request before you order.
The W in the code specifies the optional 5 um filter element instead of the standard 40 um grade, for finer water and particulate removal ahead of sensitive equipment. The K code adds a reverse/check valve that holds downstream pressure if the upstream supply drops. Both are decodable order options, as are the drain type, gauge scale and NPT thread.
