The AirTAC GFR40010MJF2WTK 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 GFR40010MJF2WTK is a size 400 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is fitted with a 3/8 in NPT port, a 5 um filter element (the finer of the two catalogue grades), a manual drain for the PC bowl, an embedded square gauge reading in psi, and a reverse/check valve that holds downstream pressure when the supply is lost. The body is supplied without a mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulation range with manual drain is 0.05-0.9 MPa (7-130 psi), and the operating temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part from the GFR400 series. The GFR line is available in sizes 200, 300, 400 and 600, with port sizes from 1/8 to 1 inch, PT / G / NPT thread options, differential-pressure, automatic or manual drains, 40 um or 5 um elements, and gauge scale choices. 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. Standard type, regulating 0.05 - 0.9 MPa (7 - 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.
| 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)). |
| (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. |
| 2 | Gauge scale: psi. 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. |
| K | Reverse-flow (reflux) valve fitted. |
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 and pressure setting for pneumatic clamps, tool-change cylinders and air-powered accessories on a machining centre, with the check valve holding set pressure through supply dips.
Filtered, regulated air to the pick-and-place cylinders and sealing jaws on a carton forming and sealing line, where the 5 um element protects close-fitting valve spools.
Conditioning the air feed to bench-top pneumatic apparatus and test rigs in a lab or pilot plant, where the psi gauge and fine element support repeatable, cleaner supply at each station.
Size 400 with a 3/8 in port sits in the middle of the GFR range; step up to size 600 or down to 300/200 depending on the flow your line needs. The 5 um element in this model suits applications where finer particulate matters; the 40 um grade is the standard choice where it does not. The manual drain means an operator opens the bowl drain at intervals, which suits attended installations; choose the automatic or differential-pressure drain codes for unattended duty. The square gauge here reads psi; MPa and bar scales are also available. PT is the standard thread and G (BSPP) or NPT are order options - this unit is the NPT version. A mounting bracket is available on other codes; this one ships without one. Flow is published as curves, not a single rating, so 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. The reflux valve permits reverse flow 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 number, so we do not quote a figure here. Tell us your line pressure, set pressure and required flow, and we will confirm the sizing from the datasheet on request before you order.
The M in the code selects the manual drain: an operator opens the bowl drain at intervals to remove collected condensate. It suits attended installations with regular checks. For unattended duty, the automatic (A) or differential-pressure (blank) drain codes are the alternatives on the same GFR400 body.
