The AirTAC GFR400C10JC2GK AirTAC Filter Regulator G3/8 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 GFR400C10JC2GK is an AirTAC GFR400 filter regulator: it removes water and particulate from compressed air and holds downstream pressure in a single body. This configuration carries a G3/8 (3/8 in) port, the standard 40 um filter element, a differential-pressure drain, and a round pressure gauge scaled in psi. A reverse/check valve is fitted, and the regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi). Maximum inlet pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing). At size 400 the bowl is polycarbonate; this code is supplied without a mounting bracket.
This is a genuine AirTAC part. The GFR series spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, and options include 5 um filtration (code W), automatic or manual drains, square or round gauges with MPa, psi or bar scales, G or NPT threads, and bracket choices. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

Feeding clean, regulated air to tool-change clamps and pneumatic fixtures on a CNC machining cell, where a stable set pressure keeps clamping repeatable across shifts.
Conditioning the air feeding pick-and-place cylinders and product diverters on a packaging conveyor line, with the 40 um element helping keep debris away from valve spools.
Regulating air to actuators on a laboratory automation skid, where the fitted check valve helps hold downstream settings if the main supply dips.
Choose the size by the port and flow step: sizes 200, 300, 400 and 600 move up through 1/8 in to 1 in ports, so step up a size when your line needs more air. This code carries the standard 40 um element; select 5 um (W) when downstream valves or instruments need finer filtration. Drain choice is differential-pressure (the default, as here), automatic (A) or manual (M). The embedded square gauge is standard, with an optional external round gauge in MPa, psi or bar scales - this code carries the round psi gauge. Thread is G (BSPP) here; PT is the standard, with G and NPT as order options. Brackets are optional and this code is without one. Flow for the GFR series is published as curves, not a single rated figure, so send us your application details and we will confirm sizing from the datasheet before you order.
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 GFR-series flow as curves rather than a single rated figure, so we do not quote a rated flow number. Send us your application details and we will confirm the flow and sizing from the datasheet on request.
In the GFR code, C2 selects the optional external round gauge with a psi scale (the embedded square gauge remains standard), and K fits a reverse/check valve that helps hold downstream pressure if the upstream supply drops. Both are catalogue options you can order with or without.
