The AirTAC GFR400C10JF1WT AirTAC Filter Regulator 3/8 in NPT 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 GFR400C10JF1WT is an AirTAC GFR400 filter regulator: one body that removes water and particulate from compressed air and regulates downstream pressure. This configuration is built for 3/8 in NPT ports, filters to 5 um (the finer of the two catalogue grades), drains condensate by differential pressure, and carries a square pressure gauge scaled in MPa. The standard-type regulator adjusts from 0.15 to 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. No mounting bracket or reverse/check valve is fitted.
This is a genuine AirTAC part. The GFR family spans sizes 200 to 600 with ports from 1/8 to 1 in, a choice of differential-pressure, automatic or manual drains, 40 um or 5 um filtration, square or round gauges with 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 figures for your application.

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.

Point-of-use conditioning ahead of machine-tool actuators and tool-changer cylinders: the 5 um element catches fine particulate, the regulator holds a steady set pressure, and the square gauge gives the operator a local reading.
Feeding test rigs and lab pneumatic circuits where clean, set air matters: the fine 5 um grade and the MPa gauge suit benches that log supply conditions, while the differential-pressure drain keeps condensate away from instruments.
Conditioning air for carton-forming and case-packing cylinders on a packaging line: one body filters and regulates, simplifying the drop, and the square gauge lets line staff verify set pressure at a glance.
Size 400 with a 3/8 in port sits in the middle of the GFR range (200/300/400/600, ports 1/8 to 1 in); step up or down a size when your flow demand changes - and because flow is published as curves rather than a single rating, ask us to confirm sizing against your application before ordering. The choices locked into this code are a 5 um filter element (instead of the 40 um standard), a differential-pressure drain, a square gauge scaled in MPa and an NPT thread (PT is the AirTAC standard; G and NPT are order options). A mounting bracket and a reverse/check valve are not fitted, and a round external gauge in psi or bar scale can be ordered as an alternative.
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 rather than a single rated figure, so we do not quote a number here. Tell us your line pressure, set pressure and expected air demand, and we will confirm the datasheet curves against your application before you order.
The W in the code selects the optional 5 um element; the catalogue standard is 40 um. Choose 5 um where downstream valves, cylinders or instruments need finer particulate removal. If your application is fine with 40 um, the same body is available in the standard grade.
