The AirTAC GFR400C15MLJF2W AirTAC Filter Regulator PT1/2 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 GFR400C15MLJF2W is an AirTAC GFR-series filter regulator: water and particulate filtration plus downstream pressure regulation combined in a single body. This size 400 unit carries a PT1/2 (1/2 in) PT thread, a 5 um filter element (the finer of the two published grades), a manual-drain polycarbonate bowl, and the low-pressure regulator type. An embedded square gauge with a psi scale is fitted so the set pressure can be read at the unit, and no mounting bracket is included.
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, a choice of differential-pressure, automatic or manual drains, 40 um or 5 um elements, square or external round gauges with MPa, psi or bar scales, and PT, G or NPT threads. Max inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Flow is published only as curves, 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.

Feeding clean, regulated air to the grippers, stopper cylinders and capping heads on a bottling line. The 5 um element protects the directional valves from water and particulate carryover, and the manual-drain bowl suits a line that is attended each shift.
Supplying regulated air to the clamps and fixture cylinders of a machining cell. The embedded square psi gauge lets the setter read and verify the clamping pressure directly at the unit, and the 1/2 in port serves a cell-level supply drop.
Running the diverter, pusher and reject cylinders on a packaging conveyor. The low-pressure regulator type is intended for circuits held at reduced settings, and the manual drain keeps condensate out of the valves on a conveyor that is checked daily.
Size and port are the first decision: GFR sizes 200, 300, 400 and 600 step up in port and flow capacity, and this unit sits at size 400 with a 1/2 in PT1/2 port - match the step to the air demand of the circuit rather than to the pipe alone. Drain type matters: this configuration has a manual drain, which you empty by hand on a schedule; automatic and differential-pressure drains are available if the bowl cannot be reached regularly. The 5 um element (code W) is the finer option against the 40 um standard - choose it where downstream valves and cylinders need cleaner air. The fitted square gauge reads in psi; MPa and bar scales and an external round gauge are alternatives. Thread is PT as standard, with G (BSPP) and NPT as order options, and this unit comes without a bracket (brackets are optional). Flow for this family is published as curves rather than a single rating, so send us your application details and we will confirm sizing from 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 family as curves rather than a single rated figure, so we do not quote a number here. Send us your application - port size, downstream demand and set pressure - and we will confirm the relevant curve and datasheet figures on request before you order.
This configuration has a manual-drain bowl: condensate is drained by hand on a schedule you set. Choose manual where the bowl is easy to reach and the installation is checked routinely. If the unit will be mounted out of reach, the automatic drain (code A) or the differential-pressure drain (the family default) removes the need for regular manual emptying.
