The AirTAC GFR600C25ALC1T 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 GFR600C25ALC1T is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This size 600 unit has a 1 in NPT port, an automatic drain that expels collected condensate without manual attention, the standard 40 um filter element, and a round pressure gauge reading in MPa. The metal bowl on this 600 size is aluminium alloy, the regulator is the low-pressure type selected for circuits working below the standard range (ask us to confirm the exact adjustment range), and the maximum inlet pressure is 1.0 MPa (145 psi) with an operating temperature of -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR series spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, drain choices (differential-pressure, automatic or manual), an optional 5 um element (code W), embedded square or external round gauges in MPa, psi or bar scales, and G/NPT thread variants to order. Flow is published as curves rather than a single rating, so we confirm sizing and datasheet figures 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.

Feeding spray-gun drops in a paint shop, where the unit strips water and particulate from the supply and holds the gun circuit at the low pressure the booth setup calls for.
Conditioning the air feeding gripper and pusher cylinders on a bottling line, keeping condensate out of the valves while the automatic drain handles collected water.
Supplying filtered, regulated air to the clamping circuit of a CNC machining centre, with the round MPa gauge giving the operator a clear setpoint reading.
Step up or down through the GFR sizes (200, 300, 400, 600) and ports (1/8 to 1 in) to match the pipe run and the air demand of the circuit; this unit is the largest size with a 1 in NPT connection. Choose the drain to suit access: automatic (fitted here) where the unit is hard to reach, manual where an operator checks the point of use, or the differential-pressure default. Filter grade is 40 um standard (fitted here) with a 5 um element available as code W where finer particulate control is needed. The gauge fitted here is the external round type reading in MPa; an embedded square gauge is the standard alternative, with psi and bar scales selectable. Thread is NPT on this code; PT is the standard and G (BSPP) is also an order option. A mounting bracket is included.
One honest routing note: flow is published as curves, not a single rated figure, so ask us to confirm sizing against your application before ordering.
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 this series as curves rather than a single rated figure, so we do not quote a number that is not in our validated data. Send us your line pressure and air demand and we will confirm the sizing from the datasheet on request.
The automatic drain expels collected condensate from the aluminium alloy bowl without anyone opening it, which suits units mounted high or in awkward spots. The regulator is the low-pressure (L) type, selected for circuits working below the standard range; the exact adjustment range for this variant is not published in the material we hold, so we confirm it on request.
