The AirTAC GFR400C10MLJC2WGK 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.
GFR400C10MLJC2WGK is an AirTAC GFR400 filter regulator: water and particulate filtration plus pressure regulation in a single body. This configuration carries a G3/8 (BSPP) port on the size-400 body, a 5 um filter element (code W), a manual drain, the low-pressure regulator type, an external round gauge with psi scale, and a built-in check valve (code K); it is supplied without a mounting bracket. The bowl is metal. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family runs from size 200 to 600 with ports from 1/8 to 1 inch, and options across the family include differential-pressure, automatic or manual drains, 40 um or 5 um elements, embedded square or external round gauges with MPa, psi or bar scales, PT, G or NPT threads, and mounting brackets. Flow is published as curves rather than a single rated figure, so ask us to confirm sizing and the low-pressure adjustment range against your application - we confirm datasheet figures on request.

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.

Filtered, low-pressure-regulated air for clamp and hold-down cylinders on a bottling line; the 5 um element helps protect cylinder seals and the manual drain suits supervised production shifts.
Pilot supply for sorting gates and diverters on conveyor lines, where the built-in check valve blocks backflow if upstream pressure dips and the round psi gauge gives operators a familiar readout.
Point-of-use filtration and low-pressure regulation on a laboratory test rig or instrument panel, where 5 um air and a low regulated setpoint are needed and the metal bowl suits the panel layout.
Size and port set the air capacity: this unit is size 400 with a 3/8 in G-thread port, and the family steps through sizes 200, 300, 400 and 600 as flow demand changes - we check the flow curves with you before ordering. Drain choice matters: manual means an operator opens the drain periodically, while automatic and differential-pressure drains discharge condensate on their own; this unit is manual. Filter grade is 5 um here (40 um is the standard grade elsewhere in the family). The gauge on this unit is the external round type reading psi; embedded square gauges with MPa, psi or bar scales are the alternatives. Threads come as PT (the standard), G or NPT as order options, and this configuration omits the mounting bracket. Because flow is published as curves rather than one rating, send us your application conditions 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 this series as curves, not as a single rated figure, so we do not quote a number. Send us your required flow and operating pressure and we will confirm from the datasheet whether this size 400, G3/8 unit is correctly sized for your application.
Manual drain means an operator opens the drain at the bottom of the metal bowl to discharge collected condensate; automatic and differential-pressure drains that do this on their own are available on other GFR variants. The L in the code marks the low-pressure regulator type - its exact adjustment range is not published in our sheet, so ask us to confirm it before ordering.
