The AirTAC GFR400C10ALJC2TK AirTAC Filter Regulator NPT 3/8 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 GFR400C10ALJC2TK is an AirTAC GFR-series filter regulator: water and particulate filtration plus pressure regulation in a single body. This size 400 unit has a 3/8 in NPT port, an automatic drain that expels collected condensate on its own, and the standard 40 um filter element. It is the low-pressure regulator type; the exact setting range for that variant is not published in our data, so we confirm it on request. A round external gauge with a psi scale is fitted, a reverse/check valve is included, and the unit is supplied without a mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. On size 400 units the bowl is polycarbonate (PC).
This is a genuine AirTAC part. The GFR family is offered in sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 in, a choice of differential-pressure, automatic or manual drains, a 5 um element option (code W), embedded square or external round gauges with MPa, psi or bar scales, and PT (standard), G or NPT threads. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing figures for your application before ordering.

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 filtered, regulated air to the low-pressure actuation circuits on a packaging line. The 40 um element removes water and particulate ahead of the regulator, the automatic drain handles condensate without daily attention, and the round psi gauge gives operators a local reading in the scale used on US plant floors.
Sits at the drop feeding a machining cell's pneumatic valves and clamps: water and particles are stripped out before regulation, the fitted reverse/check valve is in line for circuits that call for one, and the 3/8 in NPT port matches common US drop plumbing.
Conditions the air for conveyor diverters, stoppers and gate cylinders on a bottling or carton line. The low-pressure regulator type is the variant chosen where circuits run at reduced settings - we confirm the exact range against the datasheet - and the automatic drain suits positions where nobody opens a drain each shift.
Within GFR400 the real, decodable choices are: the size and port step (200/300/400/600 with 1/8 to 1 in ports) matched to the air your line needs; drain type - this unit has the automatic drain, while differential-pressure (the default) and manual variants exist in the family; filter grade - 40 um standard here, 5 um with code W; gauge - this configuration carries an external round gauge on the psi scale, with embedded square gauges and MPa or bar scales available; thread - PT is the standard, G and NPT are order options, and this unit is NPT; and bracket - this unit is supplied without one, bracket-included variants exist. Because flow is published as curves and not as a single rated figure, 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.
AirTAC publishes GFR400 flow as curves, not as a single rated figure, so we do not quote a number. Send us your application details and we will confirm the flow and sizing figures from the datasheet before you order.
Code A fits the automatic drain, which expels collected condensate without anyone opening it - useful at inaccessible or unattended points. The same GFR400 family is also available with the differential-pressure drain (the default) or a manual drain; tell us which you want when ordering.
