The AirTAC GFR600C25ALF1T 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 GFR600C25ALF1T is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure at your setting, in a single body. This size 600 unit is built with a 1 in NPT port, an automatic drain that ejects collected condensate without manual attention, a 40 um standard filter element, and an embedded square gauge scaled in MPa. The regulator is the low-pressure type, intended where the working pressure sits below the standard regulator band; ask us to confirm the exact adjustment range for your setpoint. The size 600 bowl is aluminium alloy, and a mounting bracket is included.
This is a genuine AirTAC part. GFR filter regulators are made in sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, and options that include manual or differential-pressure drains, a 5 um element (code W), psi or bar gauge scales, an external round gauge, G (BSPP) or NPT threads in place of the PT standard, and a no-bracket variant. AirTAC publishes flow for this family as curves rather than a single rated figure, so send us your application and we will confirm the 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 clean, regulated air to the gripper cylinders and vacuum ejectors on a palletiser, where the automatic drain keeps condensate out of the valves during long unattended runs.
Setting a stable, below-standard working pressure on a small pneumatic press or clamping fixture, with the square MPa gauge giving the operator a clear setpoint readout.
Conditioning air at a paint spray booth manifold: the 40 um element strips water and pipe scale before the regulator feeds the guns, with no oil mist added to the finish.
Size and port step up together: 200 through 600, with this unit at the top of the range on a 1 in NPT port - choose the size whose flow curve covers your demand with margin, and confirm it with us before ordering since AirTAC publishes flow as curves, not a single rating. Drain choice on a GFR is differential-pressure (default), automatic (this unit) or manual; automatic suits points that are hard to reach or run long shifts. The filter element is 40 um as standard or 5 um with code W - pick 5 um only where downstream equipment demands finer air. Gauge scales can be ordered in MPa, psi or bar, and the square gauge is embedded while an external round gauge is optional. Thread is PT as the AirTAC standard with G (BSPP) and NPT as order options; a no-bracket variant (code J) is also available. For setpoints below the standard regulator band, this low-pressure type is the right pick - confirm the range with us.
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 curves, not as a single rated figure, so we do not quote a number here. Send us your operating pressure and demand and we will confirm the flow curve and sizing from the datasheet on request.
This unit carries code A, the automatic drain, which ejects collected condensate without anyone opening the bowl - useful for unattended or hard-to-reach installations. The same size 600 filter regulator can be ordered with a manual drain (M) or the differential-pressure default instead, and the element can be swapped to the 5 um grade with code W.
