The AirTAC GFR600-25T 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 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 GFR600-25T is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and sets downstream pressure in a single body. This configuration is the size 600 unit with a 1 in NPT port, an automatic drain that discharges collected condensate without manual attention, standard 40 um filtration, an aluminium alloy bowl, a fitted embedded square gauge scaled in bar, and a standard regulator with a 0.15-0.9 MPa (20-130 psi) setting range. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -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 is available with manual or differential-pressure drains, a 5 um filter element, different gauge scales, PT or G threads, and with or without a mounting bracket. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures for your application.

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.

Feeds clean, pressure-set air to the filler and capper actuators on a beverage bottling line, with the automatic drain clearing condensate through long production shifts.
Conditions the shop-air feed to a CNC cell's pneumatic clamps and tool-change cylinders, holding a stable regulated pressure while the 40 um element stops pipe scale and water.
Supplies the diverter and stopper cylinders on a carton-packaging conveyor, where the 1 in NPT port serves a high-consumption header and the gauge lets operators verify set pressure at a glance.
Size 600 with a 1 in NPT port is the largest step in the GFR range; step down to 200/300/400 if your line is smaller, since port size tracks the flow the unit can pass. Drain choice matters: automatic (this model) empties the bowl on its own, manual requires operator attention, and differential-pressure drain discharges on pressure drop. The standard element is 40 um; specify the W option for 5 um where finer filtration is needed. The embedded square gauge here reads in bar; MPa and psi scales are available, and an external round gauge is optional. Thread is NPT on this unit; PT is the catalogue standard and G is also an order option. A mounting bracket is included.
Flow for this family is published as curves, not a single rated number, so send us your application details 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. 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 we do not quote a rated flow number. Tell us your application and we will confirm the relevant flow figures from the datasheet on request before you order.
The A in the code GFR60025AF3T means the bowl drains collected condensate automatically, which suits unattended or high-humidity installations. The GFR family is also available with manual drain or differential-pressure drain; the drain type also affects the regulator setting range, so confirm the option you need with us.
