The AirTAC GFR600C25AF3T 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 GFR600C25AF3T is a size-600 filter regulator that removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration has a 1 in NPT port, an automatic drain that expels collected condensate without manual attention, a 40 um standard filter element, an embedded square gauge scaled in bar, and the standard regulator with an adjustment range of 0.15-0.9 MPa (20-130 psi). Maximum inlet pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing). The size-600 bowl is aluminium alloy, and a mounting bracket is included.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, PT as the standard thread and G or NPT as order options, plus a choice of differential-pressure, automatic or manual drain and a 5 um (code W) filter element where finer filtration is needed. Flow for this series is published as curves rather than a single rated figure, so ask us and we will confirm the datasheet flow 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.

Installed at the take-off point of a 1 in compressed-air ring main serving assembly cells, cleaning water and scale from the air while holding a steady regulated pressure to the cell drops, with the automatic drain handling condensate between shifts.
Feeding the pneumatic cylinders and stopper gates on a bottling hall conveyor, where the filter section keeps moisture and debris out of the valves and the regulator holds consistent pressure so indexing and gating stay repeatable.
Supplying filtered, regulated air to a workshop test bench for commercial-vehicle air brake and door systems, with the 1 in NPT port matching the bench supply line and the bar-scaled gauge giving the technician a direct pressure readout.
Size 600 with a 1 in port is the largest step in the GFR range, so size the unit against the flow your line actually draws - the catalogue publishes flow as curves, not a single rating, so ask us to confirm sizing against your application before ordering. This unit carries the automatic drain, which suits unattended duty; manual and differential-pressure drains are the alternatives on other configurations. The 40 um element is the standard grade, with a 5 um element (code W) available where finer filtration is required. The fitted square gauge is scaled in bar, and MPa or psi scales plus an external round gauge are the other gauge choices. Thread is NPT on this code; PT is the catalogue standard and G (BSPP) is also an order option. A mounting 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 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 datasheet flow figures for this unit on request before you order.
The A in the code GFR600C25AF3T means the bowl drains condensate automatically, which suits installations that are not checked daily. The catalogue also offers manual drain (code M) and differential-pressure drain (the default) on GFR units, so you can choose the drain type that matches how the unit is maintained.
