The AirTAC GFR Filter Regulator GFR400C15JC1WK 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 GFR400C15JC1WK is an AirTAC G-series filter regulator: one body that strips water and particulate from compressed air and holds downstream pressure steady. This 400-size configuration carries a 1/2 in PT port, a 5 um element for finer filtration than the standard 40 um grade, a differential-pressure drain, an external round pressure gauge scaled in MPa, and a built-in reverse (check) valve that keeps the set pressure from bleeding back. No mounting bracket is included with this code.
This is a genuine AirTAC part. The GFR filter-regulator family is offered in sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in and thread options PT (standard), G (BSPP) or NPT; drain choices are differential-pressure, automatic or manual and the element is 40 um standard or 5 um (W). Flow for this series is published as curves rather than one rating, so we confirm datasheet 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.

Conditioning the shop-air feed to a CNC machining center's pneumatic tool-changer and clamping circuits: clean, dry air at a set pressure before the machine's solenoid valves.
Feeding the pneumatic control valve bank on a bottling line, where the 5 um element helps keep fine particulate out of the valve spools and the regulator holds a steady setting.
Supplying filtered, regulated air to diverter and stopper cylinders on a packaging conveyor, with the check valve holding the set pressure against backfeed from the manifold.
Size 400 with a 1/2 in PT port suits lines whose air demand sits above what a 300-size, 3/8 in unit can pass; step up to 600 or down to 300 according to the port of your downstream equipment. The differential-pressure drain bleeds condensate as the pressure across the bowl changes, while automatic (A) and manual (M) variants are orderable on the same body. The 5 um (W) element is the right pick where finer dirt holding matters; 40 um remains the standard grade. Gauge options are the embedded square gauge or this external round gauge, with MPa (1), psi (2) or bar (3) scales; PT is the standard thread with G and NPT as orderable options, and the J code here means you should order a bracket separately.
Flow is published as curves, not a single rating, so 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, not as a single rated figure, so we do not quote one number here. Send us your line pressure, downstream demand and allowable pressure drop and we will confirm the sizing from the GFR400C15 datasheet on request.
K indicates a reverse (check) valve is fitted, so air cannot flow back through the unit and the regulated setting is held. Codes without K have no check valve. The J in this code also means no mounting bracket is included - order one separately if you need panel or wall mounting.
