The AirTAC GFR600C25ALJC1WT AirTAC Filter Regulator NPT1 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 GFR600C25ALJC1WT is a size 600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration carries a 1 in NPT port, a 5 um filter element (the finer of the two published grades), an automatic drain that discharges collected condensate without manual attention, low-pressure regulation, a fitted round gauge scaled in MPa, and no mounting bracket. The metal bowl on this 600 size is aluminium alloy. Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family is published in sizes 200, 300, 400 and 600 with a choice of port, thread (PT standard, G and NPT as order options), drain type, filter grade, gauge style and scale, and bracket. Flow is published as curves rather than a single rated figure, so we confirm the datasheet and sizing 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.

Feeding clean, regulated air to case packers and carton sealers on a packaging line, with the automatic drain handling condensate so the unit can sit where nobody walks each shift.
Conditioning the air delivered to paint-spray guns and atomizing nozzles in a finishing booth, where the 5 um element helps keep water and particulate out of the finish.
Supplying filtered, regulated air to clamping cylinders and swing clamps on a machining or assembly fixture, with the fitted MPa gauge giving the operator a local pressure reference.
Size 600 with a 1 in port sits at the top of the GFR range, so step up or down through 200/300/400/600 against the flow your line needs - and ask us to confirm the flow curve before ordering, since AirTAC publishes flow as curves, not a single rating. This unit pairs an automatic drain with a 5 um element: choose automatic where the unit is hard to reach, manual or differential-pressure drain where preferred, and 5 um (code W) where finer filtration matters versus the 40 um standard. The fitted round gauge reads in MPa; square embedded gauges and psi or bar scales are the other published options. Thread is NPT here, with PT standard and G available to order; brackets are optional (this configuration is without one). The low-pressure regulator type suits circuits held at reduced controlled pressure - confirm the exact regulation range with us, as it is not published in the standard table.
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 number, so we do not quote a figure that is not in the datasheet. Tell us your application and we will confirm the flow curve and sizing for this 1 in NPT unit on request.
The automatic drain on this unit discharges collected condensate on its own, which suits installations that are not checked daily. AirTAC also publishes manual and differential-pressure drain options on GFR filter regulators, and the 5 um element here can be ordered as the 40 um standard grade instead - both are specification choices made at order time.
