The AirTAC GFR40010JF3WT AirTAC Filter Regulator 3/8 NPT 5 um is a genuine G-series filter regulator: water separation, 5 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 GFR40010JF3WT is an AirTAC GFR400 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body, with a drain bowl but no lubricator. This configuration has a 3/8 in NPT port, the 5 um filtration element (the finer of the two grades), a differential-pressure drain and an embedded square gauge scaled in bar. Maximum inlet pressure is 1.0 MPa (145 psi), the regulator adjusts from 0.15 to 0.9 MPa (20-130 psi), and the operating temperature is -5 to 70 C (non-freezing). The bowl is polycarbonate (PC); only size 600 uses aluminium alloy.
This is a genuine AirTAC part. The GFR series is offered in sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, PT as the standard thread and G or NPT as order options, plus choices of drain type, filter grade, gauge scale and bracket. Flow is published as curves rather than a single rating, so we confirm flow and other datasheet figures 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.

| 10 | Port size PT3/8". This body offers 10 = PT3/8", 15 = PT1/2". |
| (blank) | Drain: Differential-pressure drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |
| (blank) | Standard type. Blank is standard, L is the low-pressure type. |
| J | Supplied without bracket. |
| (blank) | Pressure gauge fitted (blank). |
| F | Gauge shape: Square. C is round, F is square. |
| 3 | Gauge scale: bar. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| T | NPT thread. PT is the default; G is BSPP and T is NPT. |
| (blank) | No reverse-flow valve (the default). |
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 conditioning for a pneumatic press or clamping station: the 5 um element keeps water and swarf out of valves and cylinders while the regulator holds the working pressure the tooling was set up for.
Filtered, regulated supply for packaging and conveyor diverters, where a steady set pressure keeps stopper, pusher and pick-and-place cylinders repeating without over-pressure wear.
Feed lab automation and test-rig manifolds with clean, regulated air; the 5 um grade and bar-scaled square gauge suit instruments and fittings that prefer a stable, low-contamination supply.
Size 400 with a 3/8 in NPT port is a mid-range step in the GFR series; step up to size 600 (1/2 to 1 in ports) or down to size 300/200 according to the flow your line needs. Drain type is a real choice: this model uses the differential-pressure drain, which bleeds condensate as air passes, while automatic (A) and manual (M) drains are order options. Filter grade is 5 um here (code W) against the 40 um standard. The gauge is the embedded square type scaled in bar, with MPa or psi scales and an external round gauge available. Thread is NPT on this code; PT is the standard and G (BSPP) is also offered. This code carries no mounting bracket (J).
Because flow is published as curves and not 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 GFR series as curves rather than a single rated figure, so we do not quote a number here. Tell us your application and we will confirm the flow and other datasheet figures for this exact model on request before you order.
This code carries the W option, a 5 um element; the standard grade for the GFR series is 40 um. Choose 5 um for instruments, valves and sensitive actuators, and 40 um for general plant air. Both grades are order options across the series, along with your choice of drain type, gauge scale and thread.
