The AirTAC GFR400C15JC3WTK 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 GFR400C15JC3WTK is an AirTAC GFR400 filter regulator: water and particulate filtration plus pressure regulation in a single body, sized for 1/2 in NPT ports. This configuration carries the 5 um filter element (code W) instead of the standard 40 um, a differential-pressure drain, a round gauge with bar scale, and a built-in reverse/check valve (K); no mounting bracket is included (J). Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulator covers 0.15-0.9 MPa (20-130 psi) with this drain type, and the operating temperature range is -5 to 70 C, non-freezing. The 400-size bowl is PC (polycarbonate).
This is a genuine AirTAC part. The GFR family is offered in sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 in, and with choices of drain type, filter grade, gauge style and scale, thread (PT standard; G and NPT to order), bracket and check valve. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing for your application.

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 conditioning for a stamping or assembly press: the 5 um element helps protect directional valves from particulate and water carryover, the regulator holds steady cylinder pressure, and the check valve holds downstream pressure if upstream air is lost.
Filtered, regulated air for stopper and diverter cylinders on a packaging or bottling conveyor, with the 1/2 in NPT ports feeding a manifold that serves several actuators from one conditioning point.
Conditioned air for pick-and-place modules and sample-handling cylinders on lab automation, where the 5 um grade and the bar-scale round gauge support repeatable, monitored setups.
Size steps from 200 through 600, so match the 1/2 in NPT port and the 400 body to the air demand of your line - we can check the published flow curves against your application before you order. The remaining choices are decodable from the code: drain type (differential-pressure here, with automatic and manual available), filter grade (40 um standard, 5 um with W, fitted here), gauge style and scale (an embedded square gauge is standard; this unit carries a round bar-scale gauge), thread (PT standard, G and NPT as order options), bracket, and the reverse/check valve fitted with code K. Because flow is published as curves, not a single rating, confirm sizing with us 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 GFR400 flow as curves, not as a single rated figure, so we do not quote a number here. Send us your line pressure and air demand and we will confirm the flow and sizing from the datasheet on request.
K indicates a reverse (check) valve is fitted, so downstream pressure is held if upstream supply is lost. Other decodable choices on this unit are the 5 um element (W), the round bar-scale gauge (C3), NPT thread (T) and no mounting bracket (J).
