The AirTAC GFR400C10JC1WT AirTAC Filter Regulator NPT3/8 5um 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 GFR400C10JC1WT is a filter regulator: water and particulate removal plus downstream pressure regulation in a single body. This size 400 unit carries a 3/8 in NPT port, a 5 um filter element (code W, finer than the 40 um standard), a differential-pressure drain that bleeds collected condensate automatically whenever the pressure differential across the element is high enough, and a round external pressure gauge scaled in MPa. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi) with this drain, and no reverse/check valve is fitted. The bowl on size 400 units is polycarbonate, and this configuration is ordered without a mounting bracket.
This is a genuine AirTAC part from the GFR filter-regulator family, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in and thread options PT (standard), G and NPT. Drain, filter grade, gauge style and scale, low-pressure type, check valve and bracket options can be selected per code. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing for your application on request.

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.

On a CNC machining cell, this unit cleans and dries the shop-air feed and holds a set pressure to the tool-changer and clamping circuits, with the 5 um element guarding fine spool valves from particulate carryover.
On a carton-forming and sealing packaging line, the unit conditions the air feeding pick-and-place cylinders and sets a stable working pressure so sealing and transfer motions repeat consistently shift after shift.
At a point-of-use drop on an automated assembly station, the unit filters the branch line, regulates pressure to the screwdriver and press actuators, and its differential-pressure drain keeps condensate moving out of the bowl without operator attention.
Step up or down through the GFR sizes (200, 300, 400, 600) and their ports (1/8 in to 1 in) against the flow your line needs - the larger the size, the larger the port and the flow capacity. Choose the drain to suit access: differential-pressure (this unit, self-acting), automatic, or manual where you want a deliberate drain action. Pick the element grade: 40 um standard or 5 um (W) for finer protection of downstream valves and cylinders - this code carries the 5 um element. Select the gauge: embedded square or external round, scaled in MPa, psi or bar (this unit: round, MPa). Thread is PT as standard with G and NPT as orderable options (this unit: NPT), and a bracket can be added if this unit is ordered without one (code J).
Flow for GFR units is published as curves, not a single rated number, so we cannot quote a rated flow here. Send us your application details and we will confirm the datasheet figures and correct size 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 GFR filter regulators as curves, not as a single rated figure, so we do not quote a rated flow, Cv or SCFM number here. Send us your line pressure, downstream demand and port requirements and we will confirm the datasheet flow curves and check the sizing against your application on request.
The W in the code GFR400C10JC1WT selects the optional 5 um filter element, one grade finer than the 40 um standard, for tighter protection of downstream components. Drain is differential-pressure (the default): collected condensate is discharged automatically whenever the pressure differential across the element is sufficient, with no manual intervention needed. If you prefer a manual-drain version, the adjustment range changes to 0.05-0.9 MPa (7-130 psi) versus 0.15-0.9 MPa (20-130 psi) on this unit.
