The AirTAC GFR400C15AJC1TK 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 GFR400C15AJC1TK is a size 400 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration is fitted with a 1/2 in NPT port, an automatic drain that expels collected condensate without manual attention, a 40 um standard filter element, a round pressure gauge with MPa scale, and a reverse/check valve. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulator adjusts from 0.15 to 0.9 MPa (20-130 psi), and the operating temperature range is -5 to 70 C (non-freezing). The polycarbonate bowl suits this size, and the unit is supplied without a mounting bracket.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch. Across the series you can order manual or differential-pressure drains, a 5 um element (code W), square or round gauges with MPa, psi or bar scales, G or NPT threads in place of the PT standard, and a mounting bracket. Flow is published as curves rather than a single rated figure, so ask us and we will 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.

Installed at the 1/2 in air drop feeding a CNC machining cell, the unit strips water and swarf-laden particulate from the shop main and holds a steady regulated pressure to the cell's valves and actuators, with the automatic drain clearing condensate through each shift.
Mounted ahead of the cylinder bank on a cartoning or case-packing conveyor, the filter regulator conditions the supply and keeps operating pressure constant so clamp and pusher cylinders cycle consistently, while the check valve holds the downstream circuit if upstream pressure dips.
Fitted upstream of a solenoid-valve manifold on an automated process skid, the unit delivers clean, moisture-reduced air at a set pressure to protect the valves and downstream components, with the MPa gauge giving operators a direct reading of the set point.
Size 400 with a 1/2 in port sits in the upper half of the GFR range; step up to size 600 or down to 300/200 depending on the flow your line needs - we can check the published flow curves against your demand before you order. The automatic drain on this unit suits unattended duty; choose a manual drain for supervised points or a differential-pressure drain where you want the bowl to dump only when the pressure drop warrants it. The 40 um element is the standard grade; specify 5 um (code W) for finer protection. The round MPa gauge is fitted here; square gauges and psi or bar scales are orderable, as are G (BSPP) and NPT threads against the PT standard. This unit comes without a bracket - add one if you panel- or wall-mount. Because flow is published as curves and not a single rating, ask us to confirm sizing against the 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, not as a single rated number, so we do not quote a figure here. Tell us your line pressure, set pressure and required air consumption, and we will confirm the flow from the datasheet curves on request before you order.
The A in the code specifies an automatic drain, which ejects collected condensate from the bowl without anyone opening it - useful on runs that operate unattended. The GFR series is also available with a manual drain or a differential-pressure drain; note that the drain type affects the regulator's adjustable range, with automatic and differential-pressure drains adjusting 0.15-0.9 MPa (20-130 psi) and manual-drain versions 0.05-0.9 MPa (7-130 psi).
