The AirTAC GFR600C25LJC2WT AirTAC Filter Regulator NPT1 Low-Pressure 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 GFR600C25LJC2WT is an AirTAC GFR-series filter regulator: one body that removes water and particulate from compressed air and regulates downstream pressure. This size 600 unit is fitted with a 1 in NPT port, a 5 um filter element (the finer W grade, versus the standard 40 um), a differential-pressure drain in the metal bowl, and a round external gauge reading in psi. It is the low-pressure (L) type, intended for circuits that work below the standard regulator band.
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, thread options PT (standard), G and NPT, drain choices, 40 um or 5 um elements, and gauge or no-gauge variants. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures for 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. 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.

Fixture clamps and swing cylinders that hold workpieces at reduced supply pressure get filtered air and a stable set pressure from one inline unit, with the psi gauge giving the operator a direct reading at the cell.
Bagging and tray-sealing machines that run their actuation circuits at low pressure use this filter regulator to strip water and fine particulate before the valves, protecting seals and keeping the set pressure steady across shifts.
Pilot regulators, positioners and low-pressure actuators on a bottling or process line need clean air at a modest, stable pressure; a 5 um element ahead of them keeps contamination out of small orifices.
Step up through the GFR sizes (200 to 600) as your port and air demand grow; this unit sits at the top of the range with a 1 in NPT connection. Choose the 5 um element (code W) when downstream equipment needs finer filtration than the standard 40 um. Pick the drain type for the bowl: differential-pressure (as fitted here), automatic, or manual. Gauges are available embedded square or external round, scaled in MPa, psi or bar - this unit carries a round psi gauge. Thread is PT as standard with G and NPT as order options; brackets are optional (this configuration has none).
Because flow is published as curves and not a single rated figure, send us your application details and we will confirm sizing and the low-pressure regulation range from 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 number, so we do not quote a figure here. Tell us your line pressure, set pressure and air demand, and we will confirm the sizing from the datasheet curves on request.
The W code in the model specifies the finer 5 um filter element instead of the standard 40 um, and C2 specifies the optional external round gauge scaled in psi. Both are catalogue options you can order with or without on other GFR600 variants.
