The AirTAC GFR400C15JC2WGK AirTAC Filter Regulator G1/2, 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 GFR400C15JC2WGK is a size-400 filter regulator that removes water and particulate from compressed air and sets downstream pressure in a single body. This configuration carries a G1/2 (BSPP) port, a fine 5 um filter element (the W grade, against the 40 um standard), a differential-pressure drain that bleeds condensate automatically whenever the pressure drop across the element is high enough, a fitted external round gauge reading in psi, and a built-in reverse/check valve that holds the downstream setting when upstream supply is lost. It is ordered without a mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulator adjustment range for this drain type is 0.15-0.9 MPa (20-130 psi), and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, a choice of differential-pressure, automatic or manual drains, 40 um or 5 um filtration, embedded square or external round gauges in MPa, psi or bar scales, and PT, G or NPT threads. Flow for this series is published as curves rather than a single rated figure, 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.

Feeding filtered, pressure-set air to a pneumatic press or clamping fixture on a machining cell, where the 5 um element protects the cylinder seals and the check valve holds the set pressure if the main supply dips.
Conditioning the air feed to conveyor diverters, case packers and bagging machinery, where the differential-pressure drain keeps condensate out of the valves and the psi gauge gives operators a visible line setting.
A filtered, regulated drop point off a factory air main serving multiple tools and actuators at a work station, with the 1/2 inch port and G thread matching standard BSPP drop piping and fittings.
Size 400 with a 1/2 inch port suits lines whose air demand sits in the upper mid-range of the G-series ladder; step up to size 600 or down to 300/200 depending on the flow curve your consumption requires - we can check the curve against your figures on request. The 5 um element in this unit is the finer of the two published grades (40 um standard, 5 um with code W); choose 5 um where downstream valves, cylinders or instruments need cleaner air. Drain is differential-pressure here; automatic (code A) and manual (code M) drains are alternatives if you want continuous bleeding or a hands-on bowl drain instead. The fitted round gauge reads psi; square embedded gauges and MPa or bar scales are the other gauge choices. Thread is G (BSPP) on this unit; PT is the catalogue standard and NPT is also an order option. Brackets are optional - this code omits one. Because flow is published as curves and not a single rating, ask us to confirm sizing against your application before you order.
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 rather than a single rated figure, so we do not quote one number. Send us your required flow and working pressure and we will confirm the sizing from the datasheet curves before you order.
The W in the code specifies the finer 5 um filter grade (40 um is the standard element), suited to protecting sensitive downstream equipment. The K code means a reverse/check valve is fitted, so the regulated downstream pressure is held if the upstream supply is interrupted. Both are decodable order options within the same GFR400 family.
