The AirTAC GFR600C25AC3TK 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 GFR600C25AC3TK is a size-600 filter regulator that removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is built for a 1 in NPT port, carries the standard 40 um filter grade, and drains condensate automatically, so the bowl empties itself during operation without a manual bleed. The regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi), a round pressure gauge scaled in bar is fitted, and a reverse (check) valve is included. The maximum working (inlet) pressure is 1.0 MPa (145 psi) and the operating 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, a choice of differential-pressure, automatic or manual drains, 40 um standard or 5 um (W) filter grades, embedded square or external round gauges with MPa, psi or bar scales, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

Dropping in at the 1 in header that feeds a packaging hall's ring main: the 40 um element strips pipe-scale and condensed water before the air reaches the distribution lines, the regulator sets a stable working pressure for the whole hall, and the automatic drain keeps the large aluminium bowl empty without daily attention.
Mounted ahead of the valve manifold that drives conveyor diverters and stopper cylinders on a bottling line: the filter stage protects the valves from water and debris, the regulator holds the cylinder pressure the line was tuned to, and the check valve keeps the circuit pressurised through brief supply dips.
Installed at the compressor room outlet feeding utility air around a truck-body fabrication plant: the 1 in NPT connection matches the plant's main drop, the 40 um grade suits general actuation and blow-off duty, and the bar-scaled round gauge lets maintenance read line pressure at a glance during rounds.
Size 600 is the largest step in the GFR range, pairing the 1 in port with the highest flow capacity of the family, so it suits main air lines rather than drop legs. Because flow is published as curves and not a single rating, ask us to confirm sizing against your required flow before ordering. On this unit the choices are already set: automatic drain (no daily manual bleeding), 40 um filtration (step down to the W-coded 5 um grade only if your downstream components demand finer filtration), a round gauge scaled in bar, and a reverse/check valve to hold downstream pressure if the supply dips. The thread here is NPT; PT is the catalogue standard and G (BSPP) is also available to order. A mounting bracket is included. If you need a different drain, grade, gauge scale or thread, we can identify the matching GFR600 variant.
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 as a single rated figure, so we do not quote a rated flow, Cv or SCFM number. Send us your line size and required flow and we will confirm the sizing from the datasheet on request before you order.
The A in the code fits the automatic drain, which expels collected condensate by itself during operation - the right choice for large size-600 bowls on main lines that are not checked daily. The family also offers manual drain (M) and the differential-pressure drain, which is the default when no drain letter appears in the code; note the manual-drain variant has a wider 0.05-0.9 MPa (7-130 psi) regulation range, while automatic and differential-pressure units adjust from 0.15-0.9 MPa (20-130 psi).
