The AirTAC GFR400C10ALC2 AirTAC Filter Regulator 3/8 in PT 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 GFR400C10ALC2 is an AirTAC GFR400 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is size 400 with a 3/8 in PT port, an automatic drain that discharges collected condensate without operator attention, a 40 um standard filter element, and a round pressure gauge reading in psi. It is the low-pressure type, a mounting bracket is included, and the unit is rated for a maximum inlet pressure of 1.0 MPa (145 psi) at -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, plus drain, filter-grade, gauge, thread and bracket options to match the line; the 400-size bowl is polycarbonate. Flow is published as curves rather than a single rating, so we confirm the datasheet 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, low-pressure regulated air holds workpieces in a CNC fixture where over-pressure could mark or distort the part, while the automatic drain keeps condensate out of the clamp cylinders.
A carton or food packaging line uses regulated low-pressure air knives to clear dust and moisture from packs before labelling, with the 40 um element protecting the nozzles from debris.
Low-pressure actuation air for diaphragm or pinch valves on a water-treatment skid, regulated below main-line pressure, with the round psi gauge giving a local setpoint readout.
Size and port set the air capacity: GFR400 carries a 3/8 in PT port, one step up from 1/4 in, so move up a size when line demand grows. Drain choice matters: automatic (this unit) discharges condensate on its own, manual needs operator attention, and the differential-pressure default reacts to a set pressure drop. Filter grade is the 40 um standard element here; specify code W for the 5 um option where finer protection is needed. The round gauge reads psi, with MPa and bar scales as alternatives, and PT is the standard thread with G and NPT available to order. Because flow is published as curves rather than one rated figure, 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 GFR400 as curves, not as a single rated figure, so we do not quote a number here. Send us your line pressure and air demand and we will confirm the datasheet flow figures for this exact model on request.
The A in the code sets the automatic drain: condensate collected in the polycarbonate bowl is discharged without an operator having to open the drain. Manual and differential-pressure drains are the other catalogue options if your installation suits a different arrangement.
