The AirTAC GFR400C10C2TK AirTAC Filter Regulator NPT3/8, 40 um 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 GFR series is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure at your setpoint in a single body. This unit is size 400 with a 3/8 in NPT port, a 40 um filtration element and a differential-pressure drain, the default drain type for the family. With the standard regulator the adjustment range is 0.15-0.9 MPa (20-130 psi), maximum inlet pressure is 1.0 MPa (145 psi), and the operating temperature range is -5 to 70 C (non-freezing). The K code adds a reverse (check) valve, and the C2 code fits the optional external round gauge reading in psi; the polycarbonate bowl suits the size 400 body.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port options from 1/8 to 1 inch, G (BSPP) and NPT threads to order against the PT standard, 5 um filtration with code W, automatic or manual drain variants, and gauge scales in MPa, psi or bar. Flow is published as curves rather than a single rating, so ask us to confirm 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 a CNC machining centre's clamping and tool-change circuits: the 40 um element and bowl strip water and swarf-laden condensate before it reaches the valves, while the regulator holds a steady setpoint at the machine drop.
Supplying carton sealers, case erectors and pick-and-place cylinders on a packaging line, where the filter section protects directional valves from moisture and the regulator keeps cylinder speed consistent as plant pressure wanders.
Conditioning the air at individual workbench drops in an assembly plant: each unit filters and regulates one station independently, so operators get stable tool pressure and the check valve helps hold the downstream setting.
Pick the size and port by the flow your line needs: sizes step 200, 300, 400 and 600, ports run from 1/8 to 1 inch, and larger sizes carry more flow. Drain type is a real choice on this family - differential-pressure (this unit), automatic with code A, or manual with code M. Filtration is 40 um standard or 5 um with code W. Gauges come as an embedded square gauge with an optional external round gauge in MPa, psi or bar scales; thread is PT as standard with G (BSPP) and NPT as order options; a mounting bracket is included unless code J is specified. Flow is published as curves, not a single rating, so send us your application and we will confirm sizing 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 figure, so we do not quote a number here. Send us your line size and air demand and we will confirm the flow and the full datasheet figures for this 3/8 in unit on request.
Yes. Gauge scale is a decode choice on this family: scale 2 is psi (as fitted here), scale 1 is MPa and scale 3 is bar. The embedded square gauge is the standard style and the external round gauge on this unit is the optional version - just tell us the scale you want when ordering.
