The AirTAC GFR400C15JC1WTK AirTAC Filter Regulator NPT1/2 5um 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 GFR400C15JC1WTK is a 400-size filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady in one body. This configuration takes a 1/2 in NPT port, carries the fine 5 um filter element (code W) instead of the standard 40 um, drains condensate by differential pressure, and is fitted with an external round pressure gauge reading in MPa. The built-in check valve (code K) holds downstream pressure if the upstream supply drops, and no mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulator adjusts from 0.15-0.9 MPa (20-130 psi), and the unit operates from -5 to 70 C in non-freezing conditions. The polycarbonate bowl suits the 400 size.
This is a genuine AirTAC part. The GFR filter-regulator family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drains, 40 um or 5 um elements, 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 and we will confirm the datasheet 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.

Feeding a pneumatic press or clamping fixture where the 5 um element protects directional valves from particles and the regulator holds a steady working pressure stroke after stroke.
Conditioning air for conveyor diverters, case packers and carton sealers, where the check valve keeps actuators from drifting if the main supply dips mid-cycle.
Supplying clean, regulated air to analytical instruments, test benches and calibration rigs that need fine 5 um filtration and a stable setpoint read on the MPa gauge.
Size and port step up together: 200, 300, 400 and 600 give progressively larger ports and flow capacity, so pick the size whose flow curve covers your demand at working pressure - this unit is the 400 size with a 1/2 in NPT port. Choose the drain to match duty: differential-pressure (as here, and it sets the 0.15-0.9 MPa / 20-130 psi adjustment range), automatic for unattended condensate removal, or manual for the widest 0.05-0.9 MPa range. Filter grade is 40 um standard or 5 um (W) for finer protection - this unit carries the 5 um element. Gauge options are the embedded square gauge or an external round gauge in MPa, psi or bar; this one is a round MPa gauge. Threads come as PT (standard), G or NPT - this unit is NPT. Brackets are optional; this configuration has none.
One honest note before you order: flow for the GFR series is published as curves, not a single rating, so send us your line conditions and we will confirm the sizing against the datasheet before you commit.
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 number here. Send us your line pressure and air demand and we will confirm the datasheet flow figures for this 400-size, 1/2 in NPT unit on request.
The W in the code selects the 5 um filter element instead of the 40 um standard, giving finer protection for sensitive downstream equipment, and the K code fits a reverse (check) valve that holds downstream pressure if the upstream supply is lost. Both are standard catalogue options on the GFR family, as are the drain type, gauge style and PT, G or NPT threads.
