The AirTAC GFR400C10MJC2WT AirTAC Filter Regulator 3/8 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 AirTAC GFR400 series combines water and particulate filtration with pressure regulation in a single filter-regulator body. This GFR400C10MJC2WT unit is built with a 3/8 in NPT port, a 5 um filter element for finer cleaning than the standard 40 um grade, a manual drain for controlled bowl blow-down, and a round pressure gauge reading in psi. The regulator is the standard type with an adjustment range of 0.05-0.9 MPa (7-130 psi), maximum inlet pressure is 1.0 MPa (145 psi), operating temperature is -5 to 70 C (non-freezing), and the size 400 bowl is polycarbonate. The unit is supplied without a mounting bracket.
This is a genuine AirTAC part. The G-series filter-regulator line spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, and options include automatic, manual or differential-pressure drains, 40 um or 5 um elements, gauge style and scale, G (BSPP) or NPT threads in place of the PT standard, a reverse/check valve, and a mounting bracket. Flow is published as curves rather than a single rating, so ask us to confirm the 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.

Feeds cleaned, pressure-regulated air to the tool changer, clamps and air-blast circuits of a machining cell, with the 5 um element helping keep fine particles out of the valves downstream.
Supplies regulated air to the cylinders on carton sealers and case erectors, where a stable set pressure keeps sealing and flap-tucking strokes consistent through the shift.
Conditions the air feeding spray guns at a booth station: the regulator holds the gun supply pressure the painter sets, and the 5 um grade supports cleaner air at the point of use.
Choose the size and port step against the air demand of the circuit: this unit is size 400 with a 3/8 in NPT port, one step in the 200/300/400/600 range that runs from 1/8 in to 1 in. Drain choice matters: a manual drain means an operator opens the bowl drain periodically, while automatic and differential-pressure drains discharge condensate without attention; this unit is manual. The 5 um element (code W) suits points where finer filtration than the standard 40 um is wanted, and the round psi gauge gives a local pressure readout. Thread is NPT here; PT is the AirTAC standard and G (BSPP) is also available to order. Because flow is published as curves rather than a single rating, send us your application details and we will confirm sizing against 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.
Flow for the GFR400 series is published 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 datasheet flow data and sizing for this unit before you order.
Manual drain means you open the drain at the bowl to expel collected condensate on a schedule you set. If the unit will be mounted where regular access is difficult, the same GFR400 series can be ordered with an automatic or differential-pressure drain instead.
