The AirTAC GFR400C10ALC2T 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 GFR400C10ALC2T is an AirTAC GFR400 filter regulator: one body that removes water and particulate from compressed air and then regulates the downstream pressure. This 400-size unit is fitted with a 3/8 in NPT port, an automatic drain that expels collected condensate without manual attention, a 40 um standard filter element, a low-pressure regulator type, and a round pressure gauge reading in psi. A mounting bracket is included and the unit carries a metal bowl. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, and with choices of drain type, filter grade (40 um standard, 5 um optional), gauge style and scale, thread (PT standard, G and NPT as options) and bracket. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

Drops feeding clamp and hold-down cylinders on a press line get filtered, moisture-managed air held at the low, stable pressure the fixtures were set up for, with the psi gauge letting setters verify the setting at the station.
On a packaging conveyor, diverters, stops and pusher cylinders run from a regulated drop: the 40 um element keeps wear particles out of the valves while the automatic drain clears condensate on a line that runs unattended between shifts.
A lab or QC test bench that needs gentle, regulated air to actuate sample holders or purge fixtures uses this unit to filter the shop supply and hold a low setpoint, with the round psi gauge giving a clear local reading for test records.
Start with the port and size: this unit is size 400 with a 3/8 in NPT port, one step up from 1/4 in, so choose it when your line needs the larger 400-size body and 3/8 in connections. The automatic drain suits points where condensate collects and nobody passes by to bleed the bowl; manual and differential-pressure drains remain available in the family if you prefer. The 40 um element is the standard grade; specify the W option for 5 um where finer filtration is wanted. The gauge here is the external round type on a psi scale; embedded square gauges and MPa or bar scales are the other catalogue choices. PT is the standard thread and G or NPT are ordered as options - this unit is the NPT variant. A bracket is included. 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 this family as curves, not as a single rated number, so there is no one l/min, m3/h or SCFM figure we can honestly quote. Tell us your application and we will confirm the flow and sizing from the datasheet on request before you order.
The A in the code selects the automatic drain, which expels collected condensate from the bowl by itself - useful at unattended drops. The family also offers a manual drain (code M) where an operator bleeds the bowl, and a differential-pressure drain as the default. This unit is the automatic-drain version.
