The AirTAC GFR40010MLJC3WT AirTAC Filter Regulator NPT3/8 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 manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The AirTAC GFR40010MLJC3WT is a GFR400-series filter regulator: filtration and pressure regulation combined in one body, with no lubricator. This configuration is built for a 3/8 in NPT port, filters to 5 um for finer protection of downstream components, and uses a manual drain, so an operator opens the bowl drain during checks rather than relying on an automatic or differential-pressure mechanism. It is the low-pressure regulator type, suited to circuits that run below standard working pressures, and it carries an external round gauge scaled in bar. No mounting bracket is included with this code.
This is a genuine AirTAC part in the GFR400 size class, one of four sizes (200/300/400/600) that step up in port size and flow capacity. Options across the series include drain type, 40 um or 5 um filtration, gauge style and scale, PT, G or NPT threads, and bracket choice. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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.
| GFR400 | G-series filter regulator, 400 body — sets the port range. |
|---|---|
| 10 | Port size PT3/8". This body offers 10 = PT3/8", 15 = PT1/2". |
| M | Drain: Manual drain — this also sets the regulating band (0.05 - 0.9 MPa (7 - 130 psi)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| J | Supplied without bracket. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. 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.

Supplies filtered, low-pressure air to clamp cylinders on a CNC fixture line, with the 5 um element protecting directional valves from particles and the manual drain cleared during shift checks.
Feeds clean, regulated air to the stopper and pusher cylinders along a packaging conveyor, where the low-pressure regulator type matches circuits that run below standard working pressures.
Conditions the air supply to textile machinery where fine particulate must be removed before air jets and guide actuators, with the bar-scaled gauge giving operators a local pressure readout.
Choose the size step (200/300/400/600) against the port and flow your line needs; this unit is the 400 size on a 3/8 in NPT port. Drain type is a real decision: manual (this code) suits periodic supervised draining, while automatic or differential-pressure drains suit unattended installations. Filtration is 5 um here (code W) for finer particle removal; 40 um is the standard grade if your circuit tolerates it. The gauge on this code is an external round type scaled in bar; embedded square gauges and MPa/psi scales are alternatives. Thread is NPT on this unit; PT is the catalogue standard and G is also orderable. This code omits the mounting bracket, so plan your own fixing. 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 this series as curves, not as a single rated figure, so we do not quote a number here. Tell us your application and required flow, and we will confirm the figures from the datasheet and check the sizing for you before you order.
The M in the code specifies a manual drain: condensate collected in the PC bowl is released by hand during routine checks. If your installation runs unattended, the same GFR400 size is available with an automatic or differential-pressure drain - ask us for the matching code.
