The AirTAC GFR60025ALC1WT AirTAC Filter Regulator NPT1 Low-Pressure is a genuine G-series filter regulator: water separation, 5 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has PT1" ports, a automatic 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 GFR60025ALC1WT is a size-600 GFR filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is built with a 1 in NPT port, an automatic drain that evacuates collected condensate from the bowl without manual attention, a fine 5 um filter element (code W, versus the standard 40 um), and the low-pressure regulator type for applications that call for reduced setpoints. It ships with a fitted round pressure gauge scaled in MPa and a mounting bracket. The size-600 bowl is aluminium alloy, and the unit carries a maximum inlet pressure of 1.0 MPa (145 psi) with an operating temperature of -5 to 70 C, non-freezing.
This is a genuine AirTAC part from the G-series air-treatment line, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, drain choices (differential-pressure, automatic or manual), filter grades (40 um standard, 5 um optional), gauge styles and scales, and PT, G or NPT threads. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm flow and datasheet figures against your application before ordering.

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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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.

Conditioned, regulated air holds workpiece clamps at a steady setpoint through a machining cycle. The 1 in NPT port feeds a manifold serving multiple clamp cylinders, the 5 um element protects the clamp valves from particulate, and the automatic drain keeps condensate out of an unmanned cell.
Test benches need clean air at a stable, often reduced pressure to keep results repeatable. The low-pressure regulator type covers reduced setpoints, the round MPa gauge gives a clear reference reading, and the automatic drain handles moisture collected during long unattended runs.
Conveyor lines use air for bottle positioning, diverters and periodic blow-off. This filter regulator sits at the line drop feeding those devices: the 5 um element keeps nozzles and cylinders from clogging, and the automatic drain clears condensate from the aluminium bowl without a daily walk-round.
Start with the size and port: the 600 frame with a 1 in port suits lines where larger piping and higher air demand are expected, and stepping down a size reduces cost where flow is modest. Choose the drain to match access: automatic drain (this unit) suits installations that are not checked daily; manual drain suits attended stations; differential-pressure is the catalogue default. The 5 um element (this unit) is the finer choice over the standard 40 um where downstream equipment is more sensitive to particulate. Gauge scale is selectable (MPa, psi or bar) and the thread is PT as standard with G and NPT as orderable options - this unit is NPT. A bracket is included on this configuration.
One honest note on sizing: AirTAC publishes flow for this series as curves, not as a single rated number, so we cannot quote a rated flow here. Send us your application's flow and pressure requirements and we will confirm the correct size against the datasheet curves 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 flow for the GFR series as performance curves rather than a single rated figure, so we do not quote a rated flow number for this unit. Tell us your required flow and working pressure and we will confirm the sizing from the datasheet curves on request before you order.
The code decodes it that way: W selects the 5 um filter element instead of the 40 um standard, and A selects the automatic drain instead of the differential-pressure default. The 5 um element suits lines with more sensitive downstream equipment, and the automatic drain suits installations that are not checked daily. If you would rather have the 40 um element or a manual drain, the corresponding catalogue code can be supplied - ask us.
