The AirTAC GFR600C25MLJC1WTK 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 GFR600C25MLJC1WTK is an AirTAC GFR600 filter regulator: one body that removes water and particulate from compressed air and then regulates the downstream pressure. This size 600 unit has 1 in NPT ports, a 5 um filter element (code W), a manual drain on the aluminium alloy bowl, and the low-pressure regulator type (code L); its exact adjustment range is not published, so we confirm it on request. A round pressure gauge scaled in MPa (code C1) is fitted, a reverse/check valve (code K) is built in, and the unit is ordered without a mounting bracket (code J). It is for compressed air only, at up to 1.0 MPa (145 psi) inlet and -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 in to 1 in, in PT (the standard), G and NPT threads, with a choice of drain type, 40 um or 5 um filtration, gauge style and scale, and bracket options. Flow is published 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.

A size 600 filter regulator at the main drop feeding big-bore clamp and press cylinders: water and scale are stripped out at 5 um and the station pressure is set locally, with the MPa gauge giving maintenance a direct reading at the header.
Where a cell runs large actuators below standard line pressure, the low-pressure regulator type is the selected variant; the manual drain lets an operator bleed accumulated water from the aluminium bowl at shift start.
Part-cleaning nozzles and blow-off manifolds need dry, particulate-free air at a set, reduced pressure: this unit filters to 5 um and holds the setting, with the fitted reverse/check valve as part of the configuration.
The real choices in this family are the size and port step against the flow your line needs (200/300/400/600 across 1/8 in to 1 in ports), the drain type (manual here; automatic and differential-pressure are available), the filter grade (5 um on this unit versus the 40 um standard), the gauge (embedded square is standard, external round optional, with MPa, psi or bar scales), the thread (PT is the standard; G and NPT are order options), and the bracket. On this model the low-pressure regulator type is selected and its exact adjustment range is not published, so ask us to confirm it. Flow is published as curves, not a single rating: tell us your application 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 flow for the GFR series as curves, not as a single rated figure, so we do not quote one number here. Tell us your line pressure and the flow your application needs, and we will confirm the sizing against the datasheet on request.
This unit carries code M, a manual drain: an operator opens it to empty accumulated water from the aluminium alloy bowl. If you prefer the bowl to discharge itself, the same size is available with an automatic drain (code A) or the differential-pressure drain that is the default - ask and we will quote the variant.
