The AirTAC GFR400C10F2TK 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 GFR400C10F2TK is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure at your setpoint in a single body. This 400-size unit is tapped NPT3/8, keeps the standard 40 um filtration grade, and uses the differential-pressure drain, which discharges condensate based on the pressure drop across the filter element. A square pressure gauge with a psi scale is fitted, a reverse (check) valve is installed on the regulated side, and the mounting bracket is included. The bowl on this size is polycarbonate, and maximum inlet pressure is 1.0 MPa (145 psi) with a working temperature of -5 to 70 C, non-freezing.
This is a genuine AirTAC part from the GFR range, which spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, PT as the standard thread and G or NPT to order, plus a 5 um (W) filtration option, automatic or manual drains, gauge scale choices and a low-pressure variant. Flow is published as characteristic curves rather than a single rating, so ask us to confirm the 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.

Conditioning the shop-air drop that feeds pneumatic clamps and tool-change cylinders on a CNC machining centre, with the fitted psi gauge letting operators verify the setpoint at a glance and the check valve holding the circuit if upstream pressure dips.
Filtered, regulated air for the diverters and pusher cylinders on a carton packaging conveyor, where the 40 um element takes out water and pipe scale before they reach the directional valves.
Feeding a spray gun in an automotive refinish booth: the regulator holds a steady gun pressure while the filter and bowl strip water and compressor carryover that would otherwise fish-eye the finish.
Size the GFR400 by port and expected air demand: this unit sits mid-range with 3/8 in NPT ports, and you can step through sizes 200, 300, 400 and 600 as your line needs less or more air. The decodable choices on this family are drain type (differential-pressure as here, automatic with A, or manual with M, which also widens the setting range to 0.05-0.9 MPa / 7-130 psi), filter grade (40 um standard, 5 um with W), gauge scale (MPa, psi or bar, embedded square as here or external round), thread (PT standard, G or NPT to order), and bracket inclusion. Flow is published as curves, not a single rating, so send us your required flow and working pressure and we will confirm sizing against 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 GFR400 flow as characteristic curves rather than a single rated figure, so we do not quote one number. Send us your required flow and working pressure and we will confirm the datasheet curve for this exact configuration before you order.
With no drain letter in the code, this unit uses the differential-pressure drain: condensate is discharged according to the pressure drop across the filter element, with no manual attention day to day. If you prefer a fully automatic drain, or a manual drain (which also widens the setting range to 0.05-0.9 MPa / 7-130 psi), the A or M variant of the same size covers it.
