The AirTAC GFR400C10ALJC2GK 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 AirTAC GFR400C10ALJC2GK is a GFR400 filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This configuration carries a G3/8 port, an automatic drain, the standard 40 um filter element, a low-pressure regulator type, an external round gauge with psi scale, and a built-in reverse (check) valve, and it is supplied without a mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. The size-400 polycarbonate bowl gives a clear view of collected condensate.
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600, with a choice of port and thread (PT is the standard; G and NPT are order options), drain type (differential-pressure, automatic or manual), filter grade (40 um standard, 5 um optional) and gauge options. Flow is published as curves rather than a single rating, so we confirm datasheet and sizing 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.

Filtered, regulated air to the clamp cylinders that hold cartons during sealing, with the low-pressure regulator type intended for circuits that work at reduced pressure and the automatic drain keeping condensate out of the valves.
Supplying the divert and stopper cylinders along a conveyor line, with the 40 um element and automatic drain protecting downstream directional valves from water and debris.
Regulated air for small pneumatic actuators on laboratory automation and sample-handling equipment, with the round psi-scale gauge giving a familiar local pressure readout at the machine.
Within the GFR400 size the real, decodable choices are: port and thread (this unit is G3/8 with G thread; PT and NPT versions exist to order), drain type (automatic here, with manual and differential-pressure alternatives), filter grade (40 um standard, 5 um with code W), gauge (this unit has the external round gauge with psi scale; the embedded square gauge is the standard fitting), the low-pressure regulator type, and the bracket (this code is supplied without one). Match the port step to your line size and air demand. Because flow is published as curves rather than a single rated figure, 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 G-series flow as curves rather than a single rated figure, so no rated flow number is stated here. Send us your line pressure and air demand and we will confirm the sizing from the datasheet on request.
The A in the code selects the automatic drain: collected condensate is discharged from the bowl without manual intervention. Manual-drain and differential-pressure-drain versions are available in the same size if you prefer a different arrangement.
