The AirTAC GFR400C10MJC1T AirTAC Filter Regulator NPT3/8 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 GFR400C10MJC1T is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single compact body. This size 400 unit has a 3/8 in NPT port, a manual drain bowl in polycarbonate (PC), a standard 40 um filter element, and a round pressure gauge with an MPa scale fitted. The regulator is the standard type with an adjustment range of 0.05-0.9 MPa (7-130 psi), and maximum inlet pressure is 1.0 MPa (145 psi). Operating temperature is -5 to 70 C, non-freezing, on compressed air only.
This is a genuine AirTAC part. The GFR family is published in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and options include automatic or manual drains, a 5 um element (code W), square or round gauges with MPa, psi or bar scales, and G (BSPP) or NPT threads in place of the PT standard. Flow is published as curves rather than a single rated figure, so we confirm the datasheet and flow figures for your application 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, regulated air feeds clamping cylinders that hold workpieces during machining, with the gauge showing set pressure at a glance on the cell.
A conditioning point for the air driving diverters, pushers and stop gates on a packaging line, keeping moisture and debris out of the actuators.
Clean, pressure-controlled air supplied to spray equipment and air-assisted applicators, with the manual drain bled down during shift-change checks.
Size 400 with a 3/8 in NPT port suits lines where moderate-to-high air demand needs a larger port than the 300 size offers; step up or down in size as flow demand changes. The manual drain means an operator opens the bowl drain periodically, which suits attended installations; automatic or differential-pressure drains are available on other codes for unattended duty. The 40 um element is the standard grade; specify the 5 um (W) option where finer filtration is needed. This code carries a round MPa-scale gauge; square gauges and psi or bar scales are order options, as are G (BSPP) and NPT threads instead of the PT standard, and a mounting bracket.
Flow for this family is published as curves, not a single rated number, so we do not quote a rated flow figure. Ask us to confirm sizing against your application and the datasheet 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 family as curves rather than a single rated figure, so we do not state a rated flow number. Tell us your application and we will confirm the flow and datasheet figures for this exact model on request before you order.
The M in the code specifies a manual drain: an operator opens the bowl drain to expel collected water, which suits attended installations. AirTAC also offers automatic (code A) and differential-pressure (blank) drains on GFR units for duty where regular manual draining is not practical.
