The AirTAC GFR400C15ALC3T AirTAC Filter Regulator NPT1/2 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 GFR400C15ALC3T is a size 400 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration has a 1/2 in NPT port, an automatic drain that discharges collected condensate from the polycarbonate bowl without manual attention, a 40 um standard filter element, the low-pressure regulator type, and an external round gauge reading in bar. A mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi), and the operating temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part from the GFR400 series. The GFR line is available in sizes 200, 300, 400 and 600 with a choice of ports, threads (PT standard, G and NPT as order options), drain types, 40 um or 5 um (W) filter grades, standard or low-pressure regulator types, gauge styles and scales, and reverse/check valve options. Flow is published as curves rather than a single rating, so ask us to confirm sizing and 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.

Filtering and regulating the air feeding clamp, seal and eject cylinders on a carton packaging line, with the automatic drain keeping condensate out of the bowl during multi-shift running.
Conditioning compressed air for paint spray guns in a finishing booth, where the low-pressure regulator type holds a reduced, stable setting at the gun and the 40 um element screens particulate.
Supplying filtered, regulated air to pneumatic diverters and stopper actuators along a conveyor line, with the included bracket mounting the unit at the line's air drop.
Size 400 with a 1/2 in NPT port suits lines where moderate-to-high air demand calls for a larger port; step up or down in the 200/300/400/600 range to match the flow your circuit needs - we can confirm the curve against your consumption before you order. The automatic drain on this unit suits unattended or hard-to-reach installations; choose manual drain where you prefer controlled discharge, or the differential-pressure default where that fits. The 40 um element is the standard grade; specify 5 um (code W) where finer particulate removal is needed. The external round gauge here reads in bar; embedded square gauges and MPa/psi scales are alternatives. PT is the standard thread, with G and NPT as order options. The low-pressure regulator type is intended for reduced downstream pressure settings; its exact adjustment range is not published, so confirm it with us on request.
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 series as curves, not as a single rated figure, so we do not quote a number here. Tell us your port size and air consumption and we will confirm the flow from the datasheet on request before you order.
The A in the code specifies an automatic drain: condensate collected in the polycarbonate bowl is discharged without manual intervention, which suits unattended installations. Manual drain and the differential-pressure drain are the other catalogue options if you prefer a different arrangement.
