The AirTAC GFR400-10C2T 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 PT3/8" 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 GFR400-10C2T is a size 400 filter regulator that removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration has a 3/8 in NPT port, the standard 40 um filter element, a differential-pressure drain that bleeds collected condensate automatically whenever the pressure differential is high enough, and a round pressure gauge reading in psi. The standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi), and the polycarbonate bowl suits non-freezing installations from -5 to 70 C.
This is a genuine AirTAC part from the GFR400 series, one of four sizes (200/300/400/600) with port options from 1/8 to 1 inch, manual or automatic drain variants, a 5 um element option, and MPa, psi or bar gauge scales. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figure 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 filtered, regulated air to a bench or floor pneumatic press, where the 3/8 in port serves the larger cylinder demand and the psi gauge lets operators set and check working pressure at a glance.
Supplying pusher and diverter cylinders on a packaging or bottling conveyor line, with the differential-pressure drain keeping condensate out of the valves during continuous shifts.
Mounted at a drop leg off the plant air main to condition and regulate air for a production cell, with the included bracket fixing the unit to the frame and the 40 um element guarding downstream components.
Size 400 with a 3/8 in port sits in the upper-middle of the GFR range, so step up to size 600 or down to size 300 depending on the flow your line needs - we will confirm the curve against your demand. Drain choice is the main running decision: this unit's differential-pressure drain needs no daily attention, while a manual drain (code M) suits supervised stations and an automatic drain (code A) suits unattended duty. The standard 40 um element protects most actuators and valves; specify the 5 um W option only where finer protection is required. This version carries the round psi gauge; square embedded gauges and MPa or bar scales are alternatives, and G (BSPP) or PT threads can be ordered instead of NPT. A mounting bracket is included. 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 GFR400 series as curves, not as a single rated number, so we do not quote a figure that could mislead your sizing. Tell us your line pressure and air demand and we will confirm the datasheet curve for this 3/8 in unit on request before you order.
The C2 code orders the optional external round gauge with a psi scale; the embedded square gauge is the standard fitting and MPa or bar scales are also available. All versions regulate across the same 0.15-0.9 MPa (20-130 psi) range, so the choice is purely about the readout your operators prefer.
