The AirTAC GFR400C10AC1TK AirTAC Filter Regulator NPT3/8 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 GFR400C10AC1TK 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 3/8 in NPT port, an automatic drain that expels collected condensate without manual attention, a standard 40 um filter element, an external round pressure gauge scaled in MPa, and a built-in reverse (check) valve. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulation range with automatic drain is 0.15-0.9 MPa (20-130 psi), and the operating temperature is -5 to 70 C (non-freezing). The polycarbonate bowl suits the 400 size frame, and a mounting bracket is included.
This is a genuine AirTAC part from the GFR filter-regulator line, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in. Related options across the range include a 5 um filter element (code W), manual or differential-pressure drains, square embedded gauges, psi or bar gauge scales, G (BSPP) or NPT threads in place of the PT standard, and low-pressure regulator variants. Flow is published as curves rather than a single rated figure, so ask us to confirm sizing and datasheet figures for your application before ordering.

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 actuators on a carton-forming or wrapping line, with the automatic drain handling condensate between shifts.
A single filter-regulator at the inlet of a control panel or manifold, giving the panel one adjustment point and one gauge instead of separate filter and regulator bodies.
Supplying the air cylinders that raise, lower and divert product on conveyor lines, where the check valve helps hold the downstream setting if upstream supply dips.
Choose the size and port step against the air demand of the circuit: this unit is size 400 with a 3/8 in NPT port, and the GFR range steps through sizes 200, 300, 400 and 600 as ports and capacity grow. Drain type is a real choice: automatic (this unit) suits points that run unattended, manual drain suits supervised stations, and differential-pressure drain is the catalogue default. Filter grade is 40 um standard or 5 um with code W if finer particulate control is needed. Gauge scale can be ordered as MPa, psi or bar, and the thread is PT as the catalogue standard with G (BSPP) and NPT as orderable options; a bracket is included here. Because flow is published as curves rather than a single rating, 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 GFR series as curves, not as a single rated number, so we do not quote a figure here. Tell us your application and we will confirm the flow and datasheet figures for this exact model on request before you order.
This configuration carries code A, the automatic drain, which discharges collected condensate from the bowl without anyone opening it. The catalogue also offers manual drain and a differential-pressure drain as the default, so pick automatic for installations that run unattended and manual where an operator is on site.
