The AirTAC GFR400C15JC3WT 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 GFR400C15JC3WT is a size-400 filter regulator: it removes water and particulate from compressed air and sets downstream pressure in one body. This configuration has 1/2 in NPT ports, a fine 5 um filter element, a differential-pressure drain that bleeds collected condensate automatically as flow passes through, and a round pressure gauge reading in bar. The standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi), the maximum inlet pressure is 1.0 MPa (145 psi), and the operating temperature range is -5 to 70 C (non-freezing). The polycarbonate bowl suits the 400 size, and this unit is ordered without a mounting bracket.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with port options from 1/8 to 1 in. Across the series you can choose thread style (PT standard, with G and NPT as order options), drain type (differential-pressure, automatic or manual), filter grade (40 um standard or 5 um), gauge style and scale, bracket and reverse-valve options. Flow figures for this series are published as curves rather than a single rating, so ask us and we will confirm the datasheet numbers 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 filtered, pressure-set air to a pneumatic press or clamping fixture, where the 5 um element protects valve spools and the regulator holds a consistent working pressure stroke after stroke.
Conditioning the air supply to conveyor diverters, case packers and bagging machinery, with the differential-pressure drain clearing condensate during normal production flow.
Serving as the point-of-use filter regulator at a 1/2 in drop from a factory air main, giving an assembly cell clean air and an adjustable, gauge-monitored supply pressure.
Start with the size and port: the 400 frame with 1/2 in NPT ports suits lines with substantial air demand, but sizing against required flow matters - flow for the G-series is published as curves, not a single rating, so send us your application details and we will confirm the right size before you order. For the element, 40 um is the standard grade for general plant air; this unit carries the 5 um (W) element for finer protection of downstream valves, cylinders and instruments. The differential-pressure drain is the default and needs no timer or operator; automatic or manual drains are available in the series if your duty suits them better.
Also decide the gauge (this unit has a round gauge with a bar scale; square embedded gauges and MPa/psi scales are options), the thread (PT is the AirTAC standard, G and NPT are order options - this unit is NPT), and whether you need the mounting bracket, which is not included under the J code. If you need lubrication as well as filtration and regulation, step up to a GFC two-unit or GC three-unit combination instead.
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 G-series as performance curves rather than a single rated figure, so no rated flow number is stated here. Tell us your application and required flow, and we will confirm the datasheet curve figures for this 1/2 in unit on request before you order.
The W code in the model number selects the optional 5 um filter grade; the GFR400 standard element is 40 um. Choose 5 um when feeding sensitive components such as precision valves, instruments or pneumatic tools, and remember the fine element loads faster, so check that the differential-pressure drain and your maintenance routine suit the duty.
