The AirTAC GFR600C25F3T AirTAC Filter Regulator NPT 1 in 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 GFR600C25F3T is a filter regulator: water and particulate removal plus downstream pressure regulation combined in a single 600-size body. This configuration carries a 1 in NPT port, a 40 um standard filter element, a differential-pressure drain on the bowl, and an embedded square gauge reading in bar. The standard regulator covers a setting range of 0.15-0.9 MPa (20-130 psi), the maximum inlet pressure is 1.0 MPa (145 psi), and the operating temperature is -5 to 70 C (non-freezing). At size 600 the bowl is aluminium alloy, and a mounting bracket is included.
This is a genuine AirTAC part. The GFR family is also available in sizes 200, 300 and 400 (with PC bowls) and in the 600 size shown here, with options including a 5 um element (code W), automatic or manual drain, gauge scales in MPa, psi or bar, an external round gauge, a reverse/check valve, and G (BSPP) or NPT threads in place of the PT standard. Flow is published as curves rather than a single rated figure, so ask us to confirm the 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.

Point-of-use conditioning at spray booths: the 40 um element strips water and pipe scale from the shop-air drop, and the regulator holds a steady downstream setting so the booth feed stays consistent through the shift.
Feeding cylinders and grippers on a packaging conveyor: filtered, regulated air at the machine inlet keeps actuator strokes repeatable, while the differential-pressure drain carries accumulated condensate away during normal running.
Conditioning the air feeding tool-clamp and chip-clearing circuits on machining centres: the combined filter regulator protects downstream valves from particulate and water and lets the setter read and hold the required line pressure in bar.
Step up or down through the GFR sizes 200, 300, 400 and 600 to match the port and the flow your line needs; this unit is the 600 size with a 1 in NPT port, the largest step in the family. Choose the drain to suit maintenance routines: the differential-pressure drain fitted here bleeds automatically with flow, while automatic (code A) and manual (code M) versions are orderable. The 40 um element is standard; specify 5 um (code W) where finer particulate protection matters. Gauge scale is selectable as MPa, psi or bar - this unit reads bar on the embedded square gauge, with an external round gauge available. Thread is PT as standard, with G (BSPP) and NPT as orderable options; a bracket is included.
Because flow is published as curves and not as a single rated number, we do not quote a rated flow here. Send us your application details and we will confirm the sizing against the datasheet curves 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 GFR flow as performance curves rather than a single rated figure, so no rated flow number is quoted here. Tell us your application - inlet pressure, downstream setting and the equipment being fed - and we will confirm the relevant figures from the datasheet on request before you order.
This GFR600C25F3T uses the differential-pressure drain, and with that drain the regulator setting range is 0.15-0.9 MPa (20-130 psi). If your application needs settings down to 0.05 MPa (7-130 psi), the manual-drain version of the same family covers that range - ask us and we will decode the correct variant for you.
