The AirTAC GFR600C25ALF2WT AirTAC Filter Regulator NPT 1 in 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 GFR600C25ALF2WT is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure in a single body. This size-600 unit is built for 1 in NPT ports, carries a 5 um filter element (code W), drains collected condensate automatically, and its low-pressure regulator is fitted with an embedded square gauge scaled in psi. The bowl on the 600 frame is aluminium alloy, a mounting bracket is included, no reverse/check valve is fitted, and the unit handles a maximum inlet pressure of 1.0 MPa (145 psi) at -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and options across the range include 40 um standard or 5 um filtration, differential-pressure, automatic or manual drains, standard or low-pressure regulation, embedded square or optional external round gauges scaled in MPa, psi or bar, 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.

Filtered, low-pressure regulated air for the grip and lift cylinders on a beverage bottling line, with the automatic drain handling condensate from a humid compressor room.
A 5 um element protecting pneumatic valves and sample-handling actuators on a laboratory analyser skid, with the square psi gauge giving a local setpoint readout.
Regulated air for diverter and stopper cylinders on a parcel sorting conveyor, where the 1 in NPT port feeds a main distribution header.
Size and port set the air capacity: this unit is size 600 with a 1 in NPT port, the largest step in the GFR range, and you can step down through 400, 300 and 200 as your demand changes. Drain choice matters: differential-pressure drains use the pressure drop across the unit, automatic drains discharge condensate on their own (as fitted here), and manual drains need periodic bleeding. Filter grade is 40 um standard or 5 um (code W) for finer protection, as on this unit. Gauges come as an embedded square gauge or an optional external round gauge, scaled in MPa, psi or bar. Threads are PT as standard with G and NPT as order options, and a bracket is included unless code J deletes it. This unit carries the L low-pressure regulator type; we confirm its adjustment range on request. Flow is published as curves, not a single rating, 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 GFR flow as curves rather than a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the flow curve and sizing from the datasheet on request.
This unit is coded A for automatic drain, which discharges collected condensate without operator attention - useful on lines that run unattended. GFR units can also be ordered with a manual drain or with the differential-pressure default; tell us which suits your maintenance routine and we will confirm the part.
