The AirTAC GFR400C10JC3TK AirTAC Filter Regulator NPT3/8 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 GFR400C10JC3TK is a size 400 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration carries a 3/8 in NPT port, a 40 um filter element, a differential-pressure drain, and a round pressure gauge reading in bar. It is the standard regulator type with an adjustment range of 0.15-0.9 MPa (20-130 psi), a maximum inlet pressure of 1.0 MPa (145 psi), and a working temperature of -5 to 70 C (non-freezing). A reverse/check valve is fitted, and the size 400 bowl is polycarbonate (PC). No mounting bracket is included with the J suffix.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, optional 5 um (W) filtration, automatic or manual drains, square or round gauges with MPa, psi or bar scales, and G, NPT or PT threads. Flow is published only as curves, so contact us and we will confirm the datasheet 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.

Feeding filtered, regulated air to the clamp cylinders on a machine-tool press fixture, where the check valve holds the set downstream pressure and the 40 um element keeps valve seats clean.
Supplying the air cylinders that raise, lower and divert cartons on a bottling or cartoning conveyor, with the bar-scale round gauge letting line staff verify set pressure at a glance.
Conditioning the air at a workshop drop for air tools and blow-off guns, where the differential-pressure drain continuously sheds accumulated condensate without interrupting production.
Start with the port and size: this unit is the 400 frame with a 3/8 in NPT port, one step up from the 300 series - choose the next size up if your line may need more flow later, since larger frames carry larger ports. The 40 um element is the standard grade; specify the W suffix if your actuators or valves need the finer 5 um option. Drain is differential-pressure here (it bleeds automatically as pressure differentials build); automatic (A) and manual (M) drains are available if your duty cycle or access needs differ. The gauge on this code is a round external gauge scaled in bar; square embedded gauges and MPa or psi scales are alternatives. PT is the standard thread, with G (BSPP) and NPT as catalogue options to order - this code is the NPT version. The J suffix means no mounting bracket is supplied; omit J if you need one. Because flow is published as curves rather than 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, not as a single rated figure, so we do not quote a l/min, SCFM or Cv number. Send us your application details and we will confirm the relevant datasheet flow curve and sizing on request before you order.
K means a reverse/check valve is fitted, so air will not back-flow through the unit. This code has no A or M in the drain position, so it uses the differential-pressure drain as standard; automatic (A) and manual (M) drain versions are available if you prefer a different drainage method.
