The AirTAC GFR60025AJC3WTK 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 automatic 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 GFR60025AJC3WTK is an AirTAC GFR600 filter regulator: filtration and pressure regulation combined in a single body. Compressed air passes a 5 um filter element (code W) that removes water and particulate, then the integral regulator sets downstream pressure anywhere in the 0.15-0.9 MPa (20-130 psi) range. The automatic drain (code A) expels collected condensate without manual attention, the 1 in NPT port suits high-flow main-line drops, and the fitted round gauge (code C3) reads outlet pressure in bar. A reverse/check valve (code K) is fitted, and this configuration ships without a mounting bracket (code J). The size 600 bowl is aluminium alloy, and the unit handles a maximum inlet pressure of 1.0 MPa (145 psi) at temperatures from -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and options for drain type, 40 um or 5 um filtration, gauge style and scale, G/NPT threads and brackets. Flow figures are published as curves rather than a single rating, so ask us and we will confirm the datasheet figures 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.

Drops feeding a machining cell need clean, dry air at a fixed setting for tool changers, clamps and pneumatic valves. This unit filters water and chips-scale particulate at 5 um, holds the set pressure, and its automatic drain keeps condensate off the floor of the main-line drop.
Packaging lines run cylinders and vacuum generators continuously; pressure drift shows up as mis-sealed cartons. A filter regulator at the line drop conditions the air and locks the working pressure, while the check valve helps hold the downstream circuit if supply pressure dips.
Test benches and lab automation need stable, finely filtered air for instruments and precision actuators. The 5 um element protects sensitive components, the bar-scale gauge gives a clear setpoint readout, and the 1 in port supports bench manifolds with high simultaneous demand.
Step up through the GFR sizes (200, 300, 400, 600) and their ports (1/8 in to 1 in) to match the air demand of the line; this 600-size unit with a 1 in NPT port is the large-port end of the range. Drain choice matters: automatic (this unit) suits unattended duty, manual suits periodic checks, and the differential-pressure default drains only when the pressure drop warrants it - note the regulation range differs by drain type (0.15-0.9 MPa for automatic and differential-pressure drains, 0.05-0.9 MPa for manual). Filtration is 5 um here versus the 40 um standard; choose 5 um where downstream valves and instruments need finer protection. The round gauge with bar scale is fitted; square embedded gauges and MPa/psi scales are alternatives. PT is the standard thread, with G (BSPP) and NPT as order options - this unit is ordered in NPT. A bracket can be added if panel or wall fixing is needed.
Because flow is published as curves rather than a single rated figure, 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. 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 number, so we do not quote a figure that could mislead your sizing. Tell us your application and required flow, and we will confirm the relevant datasheet curve values for this 600-size, 1 in NPT unit on request before you order.
This model carries drain code A: condensate collected in the aluminium alloy bowl is expelled automatically, which suits unattended or hard-to-reach installations. With the automatic drain, the regulator adjustment range is 0.15-0.9 MPa (20-130 psi); manual-drain variants open a wider 0.05-0.9 MPa (7-130 psi) range if you ever need very low setpoints.
