The AirTAC GFR400C15JC2WT AirTAC Filter Regulator NPT1/2, 5 um 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 GFR400C15JC2WT is a size 400 GFR filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration is threaded NPT1/2 (1/2 in), carries the fine 5 um filter element (code W) instead of the standard 40 um, drains condensate automatically by differential pressure, and is fitted with a round pressure gauge reading in psi. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), maximum inlet pressure is 1.0 MPa (145 psi), and the operating temperature range is -5 to 70 C (non-freezing). The bowl on this size is polycarbonate, and no mounting bracket is included with this code (bracket available as an option); no reverse/check valve is fitted.
This is a genuine AirTAC part. The GFR family is offered in sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, a choice of differential-pressure, automatic or manual drain, 40 um or 5 um filtration, standard or low-pressure regulation, embedded square or external round gauges in MPa, psi or bar scales, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet and sizing figures for your application before ordering.

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.

Feeds clean, regulated air to the tool-clamp and pallet-change circuits of a CNC machining centre, with the 5 um element protecting tight-tolerance valves from fine particles and the psi gauge letting setters dial in clamp pressure at the machine.
Mounted ahead of the valve manifold on a cartoning or case-packing line, it strips condensate and fine debris before the directional valves and holds a steady set pressure so sealing cylinders and vacuum generators repeat stroke after stroke.
Placed at the drop of a final-assembly line where air tools and torque cylinders run continuously, it conditions the supply to 5 um cleanliness and gives supervisors a visible psi reading to keep tool pressure within the specified band.
Size 400 with a 1/2 in port sits in the upper-middle of the GFR range; step up to size 600 or down to size 300 depending on the flow your line needs - we will check the published flow curves against your demand if you send the application details. This unit already carries the fine 5 um element (W); choose 40 um where only coarse water and particle removal is needed. Drain is differential-pressure here, which passes condensate using the pressure drop across the element; specify automatic (A) or manual (M) drain if you prefer. The round gauge in this code reads psi; square embedded gauges and MPa or bar scales are alternatives. The thread is NPT; PT is the standard thread and G (BSPP) is also an order option. A mounting bracket can be added if the unit will not be piped-supported. Flow is published as curves, not a single rating, so ask us to confirm sizing against the 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 GFR series as curves, not as a single rated figure, so we do not quote a l/min or SCFM number. Send us your application details and we will confirm the relevant flow-curve and datasheet figures for this 1/2 in, size 400 unit on request.
The W code in GFR400C15JC2WT selects the optional 5 um filter grade; the catalogue default for GFR units is 40 um. Choose 5 um where downstream valves, cylinders or instruments need finer particle removal, and 40 um where coarse water and dirt stripping is enough. Both grades fit the same size 400 body, and the differential-pressure drain works with either.
