The AirTAC GFR400C10LJC2WG AirTAC Filter Regulator G3/8 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 GFR400C10LJC2WG is an AirTAC GFR400 filter regulator: it removes water and particulate from compressed air and holds a set downstream pressure in a single body, with a drain bowl and a regulator but no lubricator. This configuration is sized for a G3/8 (3/8 in) port with G (BSPP) thread, carries a 5 um filter element, drains by differential pressure, and is the low-pressure regulator type fitted with an external round gauge scaled in psi. A mounting bracket is not included. Maximum inlet pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing).
It is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, and can be ordered with manual or automatic drain instead of the differential-pressure drain, a 40 um standard element instead of 5 um, an embedded square gauge or an external round gauge scaled in MPa, psi or bar, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures for your application.

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.

Conditioning the air feeding spray guns in a finishing booth: the 5 um element keeps particulate out of the gun supply while the regulator holds the set line pressure steady, all in one body.
Supplying cylinder-driven diverters and pushers on a packaging conveyor, where one combined unit handles both water and particulate removal and the downstream pressure setting.
Feeding low-pressure pneumatic circuits on a laboratory or test bench, where the low-pressure regulator type and a psi-scaled round gauge suit instruments set and read in psi.
Choose the size by port and flow: this unit is size 400 with a G3/8 port, and the family steps from size 200 to 600 if your circuit needs a different port. Drain comes as differential-pressure (this unit), automatic (code A) or manual (code M). Filter grade is 5 um here (code W); the standard element is 40 um if coarser filtration suits the line. The gauge is an external round type scaled in psi; an embedded square gauge and MPa or bar scales are the alternatives. Thread is G (BSPP); PT is the standard thread and NPT is also an order option. This unit is the low-pressure regulator type and is supplied without a mounting bracket (code J). Flow is published as curves, not a single rating - ask us to confirm sizing against your application before ordering.
Quick checklist
The PC bowl must not be cleaned with solvents — wipe it with a dry cloth. 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 GFR400 as curves rather than a single rated figure, so we do not quote a number here. Tell us your application and we will confirm the flow and datasheet figures for this 3/8 in filter regulator on request.
The W code in the model sets the 5 um filter element instead of the 40 um standard, and the C2 code fits an external round gauge scaled in psi; MPa and bar scales are alternatives. The regulator is the low-pressure type - ask us to confirm its set range on request.
