The AirTAC GFR400C15JC2WTK 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 GFR400C15JC2WTK is an AirTAC GFR400 filter regulator: one body that removes water and particulate from compressed air and then regulates downstream pressure. This size 400 unit is threaded NPT1/2 (1/2 in), carries the fine 5 um filter element (code W) instead of the 40 um standard element, and drains its bowl by differential pressure, so collected condensate is expelled automatically whenever the pressure differential across the element is high enough - no daily manual draining. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), and this configuration is fitted with an external round gauge scaled in psi plus a reverse (check) valve, so set pressure is held if the upstream supply is interrupted. No mounting bracket is included (code J).
This is a genuine AirTAC part. The GFR filter-regulator family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, a choice of PT (standard), G or NPT thread, manual, automatic or differential-pressure drains, 40 um or 5 um elements, gauge styles and scales, and optional check valves or brackets. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and flow 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.

Filter and regulate the 1/2 in air feed to a workshop pneumatic press or clamping fixture, with the 5 um element protecting directional valves and the check valve holding clamp pressure if the main supply dips.
Condition and regulate air for carton-forming and case-sealing machinery, where the differential-pressure drain keeps condensate out of the actuators during continuous shifts without daily bowl draining.
Fit at the 1/2 in drop point feeding an assembly cell's air tools and cylinders, using the psi round gauge for quick set-point checks and the 5 um element to guard downstream FRL-fed equipment.
Size 400 with a 1/2 in port sits in the upper half of the GFR range - step up to size 600 or down to 300/200 depending on the flow your line needs, and match the port to your piping (this unit is NPT; PT is the catalogue standard and G is also orderable). Choose the 5 um element (this unit) where downstream valves, cylinders or instruments need finer filtration than the 40 um standard element. The differential-pressure drain of this unit suits duty where the filter is under steady flow and you want condensate ejected without operator attention; pick a manual drain for intermittently used lines. The round psi gauge is readable at a glance for US-standard pressure settings, and the fitted check valve keeps the regulated set point intact during supply drops. 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 number here. Tell us your application and we will confirm the flow figures from the datasheet on request before you order.
The W in the code specifies the 5 um filter element instead of the 40 um standard, giving finer protection for downstream valves and cylinders, and the K specifies a reverse (check) valve that holds the regulated downstream pressure if the upstream supply is interrupted. Both are standard catalogue options on the GFR400.
