The AirTAC GFR60025F3T 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 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 AirTAC GFR60025F3T is a filter regulator: it removes water and particulate from compressed air and holds a regulated downstream pressure in a single body. This size 600 unit is built for 1 in NPT ports, filters to the standard 40 um grade, and drains condensate by differential pressure. The regulator is the standard type with a 0.15-0.9 MPa (20-130 psi) setting range, a square pressure gauge scaled in bar is fitted, and maximum inlet pressure is 1.0 MPa (145 psi). At size 600 the bowl is aluminium alloy, operating temperature is -5 to 70 C (non-freezing), and a mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and can be ordered with a 5 um element (code W), automatic or manual drain, MPa or psi gauge scales, and G or NPT threads instead of the PT standard. Flow for this model is published as a curve rather than a single rated figure, so ask us to confirm sizing against 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.

| F | Gauge shape: Square. C is round, F is square. |

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.

Clean, regulated air for a machining centre's clamps, tool changer and air blast - the 1 in NPT port suits a main drop feeding the whole cell.
Feeding filler, capper and reject-gate cylinders on a beverage line, where water carry-over and pressure drift both need control at one point.
Supplying tape heads and pusher cylinders on a packaging conveyor, with the bar-scaled gauge giving operators a local setpoint check.
Choose GFR when one body must both clean the air and set pressure. Step through sizes 200, 300, 400 and 600 - with ports from 1/8 to 1 in - until the port matches your line; because flow is published as curves rather than a single rating, ask us to confirm the curve against your required flow before ordering. Drain type is a real choice: this model uses differential-pressure drain (0.15-0.9 MPa setting range), while manual drain widens the range to 0.05-0.9 MPa and automatic drain suits unmanned installations. The 40 um element is standard; specify W for 5 um where finer filtration is needed. The fitted square gauge reads in bar, with MPa and psi scales as order options. Thread here is NPT; PT is the standard and G is also available. A bracket is included.
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 curves, not a single rated figure, so we do not quote a number here. Tell us your inlet pressure, downstream setpoint and required flow, and we will confirm from the datasheet whether this size 600, 1 in NPT unit suits your application before you order.
This configuration carries the embedded square gauge with a bar scale (code F3). MPa and psi scales are catalogue options on the same gauge, and an external round gauge is also available - just specify the scale you want when ordering.
