The AirTAC GFR400C10JF3TK AirTAC Filter Regulator NPT 3/8 in 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 GFR400C10JF3TK is a GFR-series filter regulator: one body that removes water and particulate from compressed air and holds the outlet pressure steady. This 400-size unit is threaded NPT 3/8 in, filters to the standard 40 um grade (5 um is available as code W), drains by differential pressure, and carries an embedded square gauge scaled in bar. A reverse/check valve (code K) is built in, and the J code means no mounting bracket is fitted. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. The bowl on the 400 size is polycarbonate; only the 600 size uses an aluminium alloy bowl.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, and each size can be ordered with a different drain type, filter grade, gauge scale, thread (PT is the series standard, with G and NPT as catalogue options), bracket and check-valve choices. AirTAC publishes flow for this series as curves rather than a single rated figure, so ask us to confirm sizing and datasheet 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, regulated air to the grippers and stopper cylinders on a bottling line, where water carry-over from the compressor would otherwise reach the directional valves.
Holding a steady outlet pressure to an air clamping or press fixture so the gripping force stays repeatable across a shift, with the 40 um element protecting the downstream valve.
Regulating air to conveyor diverter and gate cylinders in a distribution centre, with the K-code reverse/check valve fitted for circuits that call for one.
Size and port step up together: 200, 300, 400 and 600 cover 1/8 in to 1 in ports, so choose the size whose flow curve covers your air consumption. This code fixes several choices: 40 um filtration (choose W for 5 um), differential-pressure drain (A gives automatic drainage, M manual), a square gauge scaled in bar (MPa and psi scales are also catalogue options), the K reverse/check valve, and no bracket (J). Thread here is NPT; PT is the standard thread for the series and G is also available to order. The regulation range for the differential-pressure drain version is 0.15-0.9 MPa (20-130 psi). If you would rather buy the functions separately, the GF, GR and GL families cover filter, regulator and lubricator on their own, and GFC/GC combine them as sets.
Because flow is published as curves, not as a single rating, send us your pressure and consumption conditions and we will confirm the right size against the datasheet 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, not as a single rated number, so we do not quote a figure here. Send us your operating pressure and air consumption and we will confirm from the datasheet whether the 400 size at NPT 3/8 in suits your application.
A blank drain position means the differential-pressure drain: the bowl drains as the pressure differential across the filter builds. Code A gives an automatic drain and code M a manual drain, and all three are catalogue choices across the GFR400 series.
