The AirTAC GFR400C10ALC1T AirTAC Filter Regulator NPT3/8 Low-Pressure 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 GFR400C10ALC1T is an AirTAC GFR-series filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This size 400 unit has a 3/8 in NPT thread, a 40 um filter element, and an automatic drain that ejects collected condensate without anyone bleeding the bowl. The regulator is the low-pressure type and is fitted with a round MPa pressure gauge. 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 (PC). A mounting bracket is included.
It is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and options including manual or differential-pressure drains, a 5 um element (code W), square or round gauges with MPa, psi or bar scales, G (BSPP) or NPT threads, and bracket choices. Flow is published as curves rather than a single rating, so ask us to confirm sizing and datasheet 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.

Mounted at the air drop of a carton-sealing or wrapping line, it filters the shop air and holds a low regulated supply to the machine's cylinders and air jets, while the automatic drain clears condensate without daily attention.
At a paint or coating station it removes water and pipe scale ahead of the gun and lets the operator set the low working pressure the finish requires; the 40 um element protects the gun's air passages.
On a conveyor line with air-operated gates, stoppers and diverters, it provides one filtered, regulated take-off point so the actuators see clean air at a stable low setting through the shift.
Choose the size by the port and flow step: size 400 with its 3/8 in NPT port sits mid-range in the family (200/300/400/600), so step up or down if your line needs a different port. This unit pairs an automatic drain - the right choice where condensate arrives steadily and nobody wants to drain the bowl by hand - with the standard 40 um element; specify the 5 um W variant only where downstream equipment needs finer filtration. The low-pressure regulator type and round MPa gauge are built into this code; square-gauge versions and psi or bar scales can be ordered. PT is the standard thread, with G (BSPP) and NPT as catalogue options - this code specifies NPT. Flow is published as curves, not a single rating, so ask us to 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 flow for the GFR series 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 A in the code means the bowl discharges collected condensate automatically, with no manual bleeding. The family is also available with a manual drain or with the differential-pressure drain that is the default, so you can order the variant that suits your maintenance routine.
