The AirTAC GFR400C10MJF2WGK AirTAC Filter Regulator G3/8, 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 GFR400C10MJF2WGK is an AirTAC GFR400 filter regulator: a single body that removes water and particulate from compressed air and then regulates downstream pressure. This configuration has a G3/8 (BSPP) port, a 5 um filtration element (the finer W grade, versus the standard 40 um), a manual-drain bowl, an embedded square gauge reading in psi, and a built-in reverse (check) valve that holds downstream pressure when the supply dips. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulator adjusts from 0.05 to 0.9 MPa (7-130 psi), and the working temperature range is -5 to 70 C (non-freezing). The polycarbonate bowl is drained by hand, and this unit is supplied without a mounting bracket (code J).
This is a genuine AirTAC part from the G-series air-treatment line, which spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, drain options (differential-pressure, automatic or manual), 40 um or 5 um filtration, gauge choices, and PT, G or NPT threads. Flow for this family is published 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 spray guns and air-assisted pumps on a finishing line, where the 5 um element catches fine particulate and the regulator holds a steady gun pressure through a shift.
Supplying cylinders and grippers on a carton-packing conveyor: the built-in check valve holds downstream pressure during brief supply dips so the machine does not lose position.
Regulating clamp cylinders on a machining cell, with the square psi gauge letting the setter verify clamp pressure at the panel and the manual drain cleared at each shift check.
The real choices on this family are the size and port step (200/300/400/600, 1/8 to 1 inch), which you set against the flow your line needs; the drain type (manual here, with differential-pressure and automatic available); the filter grade (40 um standard, 5 um as on this unit); the gauge scale (MPa, psi or bar); the thread (PT standard, G or NPT to order); and whether a mounting bracket is included. Because AirTAC publishes flow as curves rather than a single rating, send us your flow and pressure requirements and we will confirm the right size 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 this family as curves rather than a single rated number, so we do not quote a figure here. Send us your required flow and working pressure and we will confirm sizing against the datasheet on request.
The M code on this unit means the bowl is drained by hand, which suits panels checked as part of a routine. The same GFR400 body is also available with a differential-pressure (default) or automatic drain, and the regulation range differs by drain type: manual-drain units adjust 0.05-0.9 MPa (7-130 psi), while automatic and differential-pressure units adjust 0.15-0.9 MPa (20-130 psi).
