The AirTAC GFR600C25AC2T 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 GFR600C25AC2T is a size 600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is built around a 1 in NPT port, an automatic drain that expels collected condensate without manual attention, a 40 um standard filter element, and a round pressure gauge reading in psi. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), and the unit includes a mounting bracket. At size 600 the drain bowl is aluminium alloy, and the maximum working (inlet) pressure is 1.0 MPa (145 psi).
This is a genuine AirTAC part. The GFR filter-regulator line 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 as well as automatic, a 5 um (W) filter element as an alternative to the 40 um standard, square or round gauges in MPa, psi or bar scales, 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 and sizing 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 on a 1 in compressed air distribution main serving a production hall, the GFR600C25AC2T filters incoming air and holds a steady regulated pressure to the plant's drop lines, with the automatic drain clearing condensate from the aluminium bowl without daily operator rounds.
On a bottling or packaging line where pneumatic cylinders, actuators and air jets share one supply, this filter regulator cleans the air and sets a consistent working pressure so downstream components behave predictably through each shift.
Feeding clamping circuits on CNC fixtures or welding fixtures, the unit removes water and particles that would foul valves and cylinders, while the psi gauge gives the setter a direct reading of the regulated clamp pressure.
Choose the size and port step against the air demand of the circuit: this unit is size 600 with a 1 in NPT port, the largest step in the GFR line, suited to lines served by 1 in piping. Drain type is a real operating choice: the automatic drain fitted here handles condensate removal unattended, while manual and differential-pressure drain versions are available where you prefer operator-controlled or pressure-differential draining. The 40 um element fitted here is the standard grade; specify the W code for a 5 um element if finer filtration is needed. Gauge options are the embedded square gauge or an external round gauge, in MPa, psi or bar scales - this unit carries a round psi gauge. Thread is NPT on this model; PT is the catalogue standard and G (BSPP) is an orderable option. A mounting bracket is included.
One honest note before ordering: AirTAC publishes flow for this family as curves, not as a single rated number, so we cannot quote a rated flow figure here. Send us your application details and we will confirm sizing against the datasheet on request.
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 family as performance curves rather than a single rated figure, so we do not quote a rated flow number for this unit. Tell us your line size, working pressure and air demand, and we will confirm the flow and sizing against the datasheet on request.
This configuration carries the A code, meaning an automatic drain that discharges collected condensate from the bowl without manual intervention. The GFR line is also available with a manual drain (M) or the differential-pressure drain that is the catalogue default, so you can choose the drain style that matches how the unit is maintained.
