The AirTAC GFR400C10JC2 AirTAC Filter Regulator PT3/8 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 GFR400C10JC2 is a filter regulator: water and particulate removal plus downstream pressure regulation combined in one body. This size 400 unit is fitted with a PT3/8 (3/8 in) port, the standard 40 um filter element, and a differential-pressure drain that bleeds collected condensate automatically whenever the pressure differential across the bowl is high enough, so no manual draining routine is needed. The standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi) under a maximum inlet pressure of 1.0 MPa (145 psi), and an external round gauge with a psi scale is fitted so the set pressure can be read directly. The polycarbonate bowl suits non-freezing compressed air from -5 to 70 C, and this configuration ships without a mounting bracket and without a reverse/check valve.
This is a genuine AirTAC part from the GFR filter-regulator series, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in up to 1 in. Within the series you can order a finer 5 um element (code W), automatic or manual drains, alternative gauge scales in MPa or bar, G (BSPP) or NPT threads, and bracket options. Flow is published by the manufacturer as curves rather than a single rated figure, so ask us to 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.

Point-of-use supply for a machine tool's pneumatic clamps and tool-change cylinders: the 40 um element strips water and swarf-laden particulate from the shop main, while the regulator holds a steady set pressure at the drop so clamp force does not wander with header pressure swings.
Feeding the pick-and-place and carton-closing cylinders on a packaging conveyor: filtered, regulated air keeps actuator stroke timing consistent through a shift, and the psi round gauge lets a line technician verify the setting at a glance without tools.
Conditioning the air line to a finishing-booth spray gun: the bowl catches water that would otherwise cause fish-eyes in the finish, and the regulator sets the gun supply pressure the painter dials in for the coating being applied.
Choose the size and port step against the air consumption of the circuit served: this unit is size 400 with a PT3/8 port, one step up from the 300 series, and the manufacturer publishes flow as curves rather than a single rating, so have us confirm the curve against your demand before ordering. The drain choice matters in practice: this unit uses the differential-pressure drain (the default), while automatic (code A) and manual (code M) drains are available if your service interval or access conditions call for them. The fitted 40 um element is the standard grade; specify the 5 um W grade if downstream equipment needs finer filtration. The round gauge fitted here reads in psi; MPa and bar scales are alternatives, and the embedded square gauge is the series standard. Thread is PT as standard, with G (BSPP) and NPT as order options, and a mounting bracket can be added if the unit will not be carried by its own piping.
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 flow performance as curves, not as a single rated number, so there is no one flow figure we can honestly quote. Send us your line pressure and the air consumption of the equipment you intend to feed, and we will confirm the sizing against the datasheet curve on request before you order.
It is the default drain type on the GFR series: condensate collected in the bowl is discharged automatically when the pressure differential across the bowl rises high enough, with no drain fitting to plumb and no manual draining routine. If you would rather control draining yourself, the manual-drain version (code M) is available, and its regulator adjustment range starts lower at 0.05 MPa (7 psi) instead of 0.15 MPa (20 psi).
