The AirTAC GFR600C25AJF1T 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 GFR600 series combines water and particulate filtration with pressure regulation in a single body. This unit is configured with a 1 in NPT port for high-flow main lines, an automatic drain that expels collected condensate without manual attention, a 40 um standard filter element, and an embedded square pressure gauge scaled in MPa. The regulator is the standard type with a setting range of 0.15-0.9 MPa (20-130 psi), and the size 600 bowl is aluminium alloy. No mounting bracket is included with this code.
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, plus options for manual or differential-pressure drains, a 5 um element (code W), G (BSPP) or NPT thread, gauge scales in MPa, psi or bar, and a reverse/check valve. Max working pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Flow for this series is published as curves rather than a single figure, so ask us to confirm the datasheet 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.

Filtering and regulating plant compressed air at the distribution header that feeds assembly stations, keeping the downstream tool circuit on a stable set pressure with condensate removed automatically.
Conditioning the shop air entering a machining centre's pneumatic panel, so clamps, tool changers and air blasts receive filtered air at the pressure the machine builder specified.
Supplying clean, regulated air to the stopper and gate cylinders along a bottling conveyor, with the automatic drain handling condensate on a line that runs through multiple shifts.
Choose the size by port and flow demand: this is size 600 with a 1 in NPT port, the largest step in the GFR range, suited to main-line supply where a smaller 200-400 unit would restrict flow. Drain choice matters: the automatic drain here suits unattended duty, while manual and differential-pressure drains are available on other codes. The 40 um element is standard; specify code W for 5 um where finer particulate removal is needed. Thread on this code is NPT; PT is the standard and G (BSPP) is also a catalogue option. A bracket can be added on other codes if panel or wall fixing is required.
Flow for the GFR series is published as curves, not a single rated number, so we cannot quote a rated flow here. Send us your application details and we will confirm sizing and the full datasheet on request 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 GFR series as curves rather than a single rated figure, so there is no one rated flow number we can quote. Tell us your application and we will confirm the flow data from the datasheet on request.
The A in the code specifies an automatic drain, which expels collected condensate without operator attention - useful on unattended or multi-shift lines. AirTAC also offers manual drains and differential-pressure drains (the default) on GFR units, so you can choose the drain type that matches how the installation is serviced.
