The AirTAC AirTAC GFR400C10MJC2 Filter Regulator 3/8 in PT 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 GFR400C10MJC2 is a filter regulator: one compact body that removes water and particulate from compressed air and holds downstream pressure at your setpoint. This size 400 unit is tapped PT3/8 (3/8 in, PT thread standard), carries a 40 um filter element, uses a manual drain for bowl condensate, and comes with a round pressure gauge reading in psi. The standard regulator covers a 0.05-0.9 MPa (7-130 psi) setting range, and the unit is rated to 1.0 MPa (145 psi) maximum inlet pressure at -5 to 70 C, non-freezing.
This is a genuine AirTAC part from the GFR400 series, one of four sizes (200/300/400/600) available with ports from 1/8 to 1 in, PT, G or NPT threads, automatic, manual or differential-pressure drains, 40 or 5 um filter elements, and MPa, psi or bar gauge scales. Flow is published as curves rather than a single rated figure, so ask us to confirm sizing and full 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.

Clean, regulated air to the clutch and cylinder circuit of a stamping press, holding the setpoint pressure while the 40 um element keeps pipe scale and rust out of the valve stack.
Stable downstream pressure for the sealing cylinders on a bagging or carton line, with the manual drain bled at shift start to clear overnight condensate from the bowl.
A filter regulator ahead of paint spray guns in a finishing booth, keeping water and grit out of the air line while the operator dials in gun pressure at the gauge.
Size and port set the air capacity: step up from size 200 to 600 as your flow demand grows, and this 400 unit takes a 3/8 in PT connection. Choose the drain to match the duty - manual (as here) needs periodic bleeding, automatic suits unattended lines, and differential-pressure drain suits steady flow. Filter grade is 40 um standard; specify the W code for a 5 um element when finer protection is needed. Gauges come embedded square or as an external round gauge, scaled in MPa, psi or bar - this unit is fitted with a round psi gauge. PT is the standard thread; G (BSPP) and NPT are order options, and a mounting bracket is optional. Flow is published as curves, not a single rating, so let us 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 GFR400 flow as curves rather than a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the flow and full datasheet figures for this unit on request.
The M in the code specifies a manual drain: condensate collects in the bowl until you bleed it off. Choose manual for attended equipment on a regular duty cycle; choose the automatic or differential-pressure drain codes for lines that run unattended.
