The AirTAC GFR400C10JF2GK AirTAC Filter Regulator G3/8, 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 GFR400C10JF2GK is an AirTAC GFR400 filter regulator: a 3/8 in (G3/8, BSPP) unit that removes water and particulate from compressed air and holds downstream pressure at your set point in a single body. This configuration carries the standard 40 um filter element with a differential-pressure drain, a standard regulator adjustable from 0.15-0.9 MPa (20-130 psi), an embedded square gauge reading in psi, and a built-in reverse (check) valve; no mounting bracket is fitted (code J). Maximum inlet pressure is 1.0 MPa (145 psi), the working temperature range is -5 to 70 C (non-freezing), and the bowl on this size is polycarbonate (PC).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and options include a 5 um element (code W), automatic or manual drains, MPa/psi/bar gauge scales, an external round gauge, G or NPT threads in place of the standard PT, and bracket or panel mounting depending on the model. Rated flow is published as curves rather than a single 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.

Point-of-use air preparation ahead of a machining center's air-operated clamps and tool-change cylinders: the 40 um element strips water and pipe scale before they reach the valves, the regulator holds the clamp circuit at its set pressure, and the built-in check valve blocks backflow toward the supply line.
Filtered, regulated air for diverters, reject gates and stopper cylinders on a filling or cartoning conveyor. The G3/8 port suits branch drops off the main header, and the psi gauge lets line technicians verify set points at a glance during changeovers.
Supply conditioning for grippers, clamps and pick-and-place actuators in a robot cell. The filter-regulator keeps moisture and particles out of the cell's valve manifold, the check valve protects the set pressure from upstream disturbances, and the no-bracket configuration suits direct mounting at the cell's air inlet panel.
Choose the size by port and demand: this 400-size unit takes a G3/8 port, and the range steps through 200/300/400/600 as your line's air consumption grows - send us your figures and we will check them against the flow curves. Drain: differential-pressure is standard on this unit; order code A for fully automatic or M for manual discharge. Filter grade: 40 um standard, 5 um (code W) for finer protection of downstream valves and cylinders. Gauge: this unit reads psi on the embedded square gauge; MPa and bar scales and an external round gauge are available. Thread: PT is the AirTAC standard, with G (BSPP, as fitted here) and NPT as order options. Bracket: this code omits the mounting bracket. Flow is published as curves, not a single rating, so confirm sizing with us 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 G-series flow as curves rather than a single rated figure, so we do not quote one number. Send us your working pressure and air consumption and we will confirm from the datasheet whether this 400-size, G3/8 unit is correctly sized for your application.
Differential-pressure drain is the standard drain type on this filter regulator. AirTAC also offers automatic (code A) and manual (code M) drains on the same sizes, so you can order the variant that suits your maintenance routine - automatic for unattended installations, manual where an operator drains at shift checks. Ask us to confirm the right option for your installation.
