The AirTAC GFR400C10MLJF2WT 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 GFR400C10MLJF2WT is an AirTAC GFR400 filter regulator: a single body that removes water and particulate from compressed air and regulates downstream pressure. This configuration is threaded 3/8 in NPT, carries a 5 um filter element (the finer of the two published grades), a manual drain for controlled bowl evacuation, a metal bowl, an embedded square gauge reading in psi, and the low-pressure regulator type. No mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part in the GFR series, which spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, a choice of manual, automatic or differential-pressure drains, 40 um standard or 5 um filtration, gauge scale options, and PT, G or NPT threads. Flow is published as curves rather than a single rating, 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.

Point-of-use air preparation for gripper and pusher cylinders on a bottling line: the 5 um element protects directional valves from particulate and the manual drain clears accumulated water at shift end.
Regulated air to pneumatic clamps on a CNC machining cell, with the embedded square psi gauge giving the operator a direct pressure reading right at the fixture.
Air preparation for diverter, stopper and reject cylinders along a packaging conveyor: one body handles filtration and regulation, and the 3/8 in NPT port drops straight into the line's drop legs.
Size 400 with a 3/8 in NPT port sits in the middle of the GFR range; step up or down (sizes 200/300/400/600, 1/8 in to 1 in) to match your piping and the flow your line needs. The 5 um element (code W) suits air feeding sensitive valves or instruments, while the 40 um standard element is the usual choice for general actuator supply. The manual drain lets you bleed the bowl on a schedule; automatic and differential-pressure drains are available where unattended water removal matters. The embedded square gauge on this unit reads in psi, with MPa and bar scales and an external round gauge as options. PT is the standard thread and G or NPT are order options; this unit is specified in NPT and is supplied without a mounting bracket.
This code specifies the low-pressure regulator type; its exact adjustment range is not published as a single figure, so confirm the setpoint you need with us before ordering. Flow for the GFR series is likewise published as curves rather than one rated number, so send us your flow requirement and we will confirm sizing from the datasheet.
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 GFR flow as curves rather than a single rated figure, so we do not quote a l/min or SCFM number here. Send us your flow requirement and port size and we will confirm sizing from the datasheet before you order.
This code specifies a manual drain: the bowl is emptied by operating the drain at intervals, which suits manned cells with a maintenance routine. The same size is available with automatic or differential-pressure drains where unattended water removal is needed. Other decode choices specific to this unit are the 5 um filter element (code W), the low-pressure regulator type, the square psi gauge, and the NPT thread with no mounting bracket.
