The AirTAC GFR600C25ALJC3WTK 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 GFR600C25ALJC3WTK is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This size 600 unit is specified with a 1 in NPT port, a 5 um filter element (the finer of the two published grades), an automatic drain that expels collected condensate without manual attention, and a reverse/check valve fitted. It is the low-pressure regulator type and carries an external round gauge with a bar scale; the maximum working (inlet) pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing). The metal bowl on this 600-size unit is aluminium alloy.
This is a genuine AirTAC part. The GFR series is published in sizes 200, 300, 400 and 600 with port options from 1/8 in to 1 in, a choice of 40 um standard or 5 um fine filtration, differential-pressure, automatic or manual drains, standard or low-pressure regulator types, gauge and scale options, and PT, G or NPT threads. Because flow is published as curves rather than a single rated figure, we confirm flow and datasheet figures 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.

Installed ahead of a 1 in valve manifold on a process skid, it filters incoming air to 5 um and holds a steady low-pressure setting to the pilot circuit, with the automatic drain clearing condensate between shifts.
Mounted at the main air drop feeding a carton-forming and sealing line, it conditions the plant supply and lets maintenance read line pressure at a glance on the bar-scale gauge without shutting the line down.
Placed on the supply to pneumatic positioners and transmitters in a process area, the fine 5 um element and low-pressure regulation protect sensitive instrument components from particles and pressure drift.
Size 600 with a 1 in NPT port is the largest step in the GFR range, so start here when the line size or the air demand at the point of use points to a 1 in connection, and step down to 300 or 400 if the circuit is smaller. The 5 um element (code W) suits downstream equipment that needs finer particulate capture than the 40 um standard element; the automatic drain is the right choice where the unit is installed in a position that is awkward to reach for manual draining. The low-pressure regulator type is intended for circuits controlled below the standard type's range - ask us to confirm the exact setting band for your setpoint. The round gauge on this configuration reads in bar; MPa and psi scales are also published options, and PT or G threads can be ordered in place of NPT. No mounting bracket is fitted on this code. Flow for this series is published as curves, not a single rating, 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 the GFR series as characteristic curves, not as a single rated figure, so we do not quote a rated flow, Cv or SCFM number. Send us your line pressure and required air demand and we will confirm the sizing from the datasheet curves on request before you order.
The A in the code sets the automatic drain, which ejects collected condensate on its own - useful where the unit is mounted out of easy reach and a manual or differential-pressure drain would depend on someone attending it. The W sets the 5 um element, the finer of the two published grades (40 um is the standard alternative), for downstream equipment that needs cleaner air.
