The AirTAC GFR400C10MJC1TK 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 AirTAC GFR400C10MJC1TK 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 on the bowl, a round pressure gauge with MPa scale, and a built-in reverse (check) valve that holds the downstream setting when upstream pressure is lost. Maximum inlet pressure is 1.0 MPa (145 psi), the regulator adjusts from 0.05 to 0.9 MPa (7-130 psi), and the operating temperature range is -5 to 70 C (non-freezing). No mounting bracket is included in this version.
This is a genuine AirTAC part from the GFR filter-regulator family, which spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in. Across the family you can order automatic or differential-pressure drains instead of manual, a 5 um element (code W), gauge scales in psi or bar, G (BSPP) or NPT threads in place of the PT standard, and bracket options. Flow is published as curves rather than a single rating, so ask us to confirm sizing figures from the datasheet 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.

Point-of-use conditioning on the air feed to a CNC machining centre: the 40 um element stops scale and pipe debris reaching solenoid valves, the regulator holds a steady setting for clamps and tool-change cylinders, and the check valve keeps that setting through upstream dips.
Conditioning the air feeding grippers and sealing cylinders on a carton or blister packaging line, where the manual drain suits a machine attended at every shift and the round MPa gauge gives the operator a visible line-pressure reference.
Filtered, regulated air for the part-clamping grippers on a robotic welding cell, with the reverse/check valve holding clamp pressure if the main supply drops mid-cycle so the workpiece stays secured.
Start with the port step: this unit is size 400 with a 3/8 in NPT port, one step up from the 1/2 in and 1/4 in choices in smaller GFR sizes - match the size to the air consumption of the circuit rather than oversizing on pipe alone. Choose the drain to suit access: this version is manual drain, which suits attended installations; automatic or differential-pressure drains suit points that are hard to reach. The 40 um element is the standard grade; specify the 5 um W element where downstream equipment needs finer filtration. The fitted round gauge reads in MPa; psi and bar scales are orderable, and the embedded square gauge is the family standard if you prefer it. Thread is NPT here, while PT is the catalogue standard and G (BSPP) is also available - order the code that matches your piping. This version omits the mounting bracket; bracketed versions exist if you need panel fixing.
One honest note before ordering: AirTAC publishes flow for this family as curves, not as a single rated figure, so send us your flow and pressure requirements and we will confirm sizing against the datasheet before you commit.
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 the GFR family as capacity curves rather than a single rated number, so there is no one figure we can quote honestly. Tell us your working pressure and air demand and we will confirm the sizing from the datasheet curves on request before you order.
The M in the code specifies a manual drain: someone opens the bowl drain to expel collected water, which suits attended installations. The same GFR400-10 body is also orderable with an automatic drain (code A) or a differential-pressure drain (blank), which suit hard-to-reach points; the manual-drain version also carries the wider 0.05-0.9 MPa (7-130 psi) regulation range.
