The AirTAC GFR40010F3T 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 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 GFR40010F3T is an AirTAC GFR400 filter regulator: one body that removes water and particulate from compressed air and regulates downstream pressure. This configuration has a 3/8 in NPT port, a 40 um standard filter element, a differential-pressure drain, a standard regulator with a 0.15-0.9 MPa (20-130 psi) setting range, a square gauge scaled in bar, and a polycarbonate bowl; a mounting bracket is included.
It is a genuine AirTAC part, available in four sizes (200/300/400/600) with PT as the standard thread and G and NPT as order options, plus automatic or manual drain variants, a 5 um element option and MPa/psi/bar gauge scales. Maximum inlet pressure is 1.0 MPa (145 psi) and operating temperature is -5 to 70 C (non-freezing). Flow is published as curves rather than a single rating, so ask us to confirm datasheet figures for your application.

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.

| F | Gauge shape: Square. C is round, F is square. |
| 3 | Gauge scale: bar. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |

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.

Feeds filtered, pressure-set air to cylinders and clamping fixtures on an assembly-line press station, holding the setpoint steady through shift-long cycling while the 40 um element keeps scale and pipe debris out of the valves.
Supplies clean, regulated air to diverters, stoppers and lift gates on a packaging conveyor line, with the square bar gauge giving operators a direct local readout of the supply pressure at the machine.
Provides a stable, filtered air supply for bench test rigs and pilot-operated instruments in a workshop or laboratory, where the differential-pressure drain clears collected condensate without interrupting the test.
Step up through the G-series sizes (200/300/400/600) against the flow your line needs; the 400 size carries a 3/8 in port here. Choose the drain to suit maintenance practice: differential-pressure (this model), automatic (A) for hands-off condensate removal, or manual (M). Pick the 40 um standard element or the 5 um (W) grade for finer protection, set the gauge scale to MPa, psi or bar, and order PT, G or NPT thread to match your piping; a bracket is included on this unit.
Because AirTAC publishes flow as curves rather than a single rated figure, we do not quote a flow number here. Send us your line pressure and downstream demand 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 flow for the GFR400 series as curves, not as a single rated figure, so we do not quote a number here. Send us your line pressure, downstream demand and allowable pressure drop and we will confirm sizing from the datasheet on request.
A blank drain position in the code means the differential-pressure drain: condensate is discharged automatically when the pressure differential across the element rises, with no timer or operator action needed. The F3 in the code selects the embedded square gauge scaled in bar; MPa and psi scales, an external round gauge, an automatic (A) or manual (M) drain, and a finer 5 um (W) element are all orderable variants in the same series.
