The AirTAC GFR400C15JC3T AirTAC Filter Regulator NPT1/2 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 GFR400C15JC3T is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and holds downstream pressure at your setpoint in one compact body. This size 400 unit is threaded NPT1/2, carries the standard 40 um filter element and a differential-pressure drain, and is fitted with an external round gauge reading in bar. The regulator is the standard type with a 0.15-0.9 MPa (20-130 psi) setting range, rated for a maximum inlet pressure of 1.0 MPa (145 psi) at -5 to 70 C (non-freezing), and no mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, plus options for automatic or manual drains, a 5 um element (code W), embedded square or external round gauges in MPa, psi or bar scales, G or NPT threads, brackets and a reverse/check valve. Flow is published as curves rather than a single rating, so ask us to confirm 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 clean, moisture-reduced and pressure-regulated air to the directional valves, clamps and tool-change actuators of a CNC machining cell, with the gauge letting the setter verify the circuit pressure at a glance.
Conditioning the air feeding the pusher, clamp and sealing cylinders on a cartoning or palletizing conveyor line, where water and scale from the compressor ring must be stripped before they reach the valves.
Supplying filtered, regulated air to impact drivers, ratchets and air screwdrivers at an assembly bench, keeping grit and condensate out of the tools while the operator holds a consistent working pressure.
Pick the size by the port and flow step: 200, 300, 400 and 600 move up through 1/8 to 1 inch ports, so step up when your line needs more air. The real choices within the family are drain type (differential-pressure as fitted here, automatic with A, or manual with M), filter grade (40 um standard, 5 um with W), gauge (embedded square as standard, or external round in MPa, psi or bar scales) and thread (PT is the standard; G and NPT are order options, as on this NPT unit). Brackets are optional. Flow is published as curves, not a single rating, so send us your application details and we will confirm sizing against 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 flow for the GFR series as curves rather than a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the flow and the full datasheet figures for this size 400, NPT1/2 unit on request.
Yes. PT is the standard thread and G (BSPP) and NPT are catalogue options to order, as on this NPT unit. Gauges come as an embedded square gauge as standard or an external round gauge with MPa, psi or bar scales; this configuration carries the external round gauge with a bar scale.
