The AirTAC GFR400C10AJF3T AirTAC Filter Regulator NPT 3/8 in 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 GFR400C10AJF3T is a size 400 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration carries a 3/8 in NPT port, an automatic drain that expels collected condensate without manual attention, a 40 um standard filter element, and an embedded square gauge scaled in bar so the set pressure is visible at a glance. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulator adjustment range with automatic drain is 0.15-0.9 MPa (20-130 psi), and the operating temperature range is -5 to 70 C (non-freezing). The polycarbonate bowl suits the 400 size frame.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with a choice of ports and threads, drain types, 40 um or 5 um (W) filtration, gauge styles and scales, and bracket options. Flow for this series 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.

Feeding clean, regulated air to the cylinders and grippers on a cartoning or wrapping line, with the automatic drain keeping condensate out of the valves during continuous shifts.
Supplying filtered air at a stable set pressure to conveyor stopper, pusher and clamp actuators, where the bar-scaled square gauge lets operators verify the setting without extra instruments.
Serving as the filter-regulator stage on a 3/8 in NPT branch feeding a machine's valve manifold, combining water and particulate removal with pressure adjustment in one body.
Size 400 with a 3/8 in NPT port sits in the upper-middle of the GFR range; step up to 600 or down to 300 depending on the flow your line needs, and confirm the fit against the published flow curves before ordering. The automatic drain on this unit keeps condensate off your downstream equipment without daily attention; manual and differential-pressure drains are available if your duty cycle or mounting position suits them better. The 40 um element is the standard grade - choose the W option (5 um) only where finer particulate protection is required. The square gauge here reads in bar; psi and MPa scales and an external round gauge are alternatives. NPT is specified on this code; G (BSPP) is the other orderable thread option. The J suffix means no mounting bracket is fitted - add the bracket variant if the unit will be panel- or wall-mounted. AirTAC publishes flow as curves, not a single rating, so send us your application conditions and we will confirm sizing from the datasheet before you order.
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 number, so we do not quote a fixed figure. Tell us your application conditions and we will confirm the relevant flow and datasheet figures for this size 400, 3/8 in NPT unit on request.
The A in the code specifies an automatic drain, which discharges collected condensate from the bowl without manual intervention. GFR400 units can also be ordered with a manual drain or the differential-pressure (blank) default, and the bowl on this 400 size is polycarbonate. Note the standard adjustment range with automatic drain is 0.15-0.9 MPa (20-130 psi).
