The AirTAC GFR400C10MJC2T AirTAC Filter Regulator, NPT3/8, psi Gauge 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 GFR400C10MJC2T is a size 400 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration carries a 3/8 in NPT port, a 40 um standard filter element, a manual drain bowl, and a round pressure gauge reading in psi. The standard regulator covers 0.05-0.9 MPa (7-130 psi) with this manual-drain setup, and the unit is rated to 1.0 MPa (145 psi) maximum inlet pressure and -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR400 series is one of four sizes (200/300/400/600) with port options from 1/8 to 1 inch, a choice of 40 um or 5 um (W) filtration, differential-pressure, automatic or manual drains, gauge style and scale choices, and G/NPT thread options. Flow is published as curves rather than a single rating, so we confirm datasheet and flow figures on request before you order.

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 conditioning on a CNC machining centre: clean, regulated air to tool-changer and clamping cylinders, with the psi gauge letting operators set and verify working pressure at the machine.
Feeding sealers, diverters and pusher cylinders on a packaging conveyor line, where the 3/8 in port matches the main drop and the manual drain is serviced during scheduled changeovers.
Conditioning and regulating air to grippers and weld-gun clamps in a robotic welding cell, with the 40 um element protecting valve spools from water and particulate carryover.
Size 400 with a 3/8 in NPT port suits lines where moderate-to-high air demand rules out the smaller 200/300 frames; step up to size 600 or down to 300 based on the flow your circuit needs. This unit has a manual drain, so someone must bleed the bowl periodically - choose an automatic or differential-pressure drain variant if the installation is unattended. The 40 um element is the standard grade; specify W for 5 um where finer particulate removal matters. The fitted round gauge reads in psi; square gauges and MPa/bar scales are alternatives, and G (BSPP) thread is available instead of NPT. No mounting bracket is included with this code (J). Flow for this series is published as curves, not a single rating, so ask us to confirm sizing against your application before ordering.
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 here. Tell us your working pressure and air demand and we will confirm the sizing from the datasheet on request before you order.
The M in the code specifies a manual drain bowl: collected condensate must be bled off by hand at intervals. It suits attended installations on a maintenance schedule. If the unit will sit unattended, ask about the automatic (A) or differential-pressure (blank) drain variants of the same GFR400 size.
