The AirTAC GFR30010MJF2WTK 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 GFR30010MJF2WTK is an AirTAC GFR300 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration has a 3/8 in NPT port, a 5 um filter element (finer than the 40 um standard), a manual drain bowl in polycarbonate, an embedded square pressure gauge reading in psi, a built-in reverse/check valve, and no mounting bracket. The standard regulator covers 0.05-0.9 MPa (7-130 psi) with this manual-drain version, and maximum inlet pressure is 1.0 MPa (145 psi). Operating temperature is -5 to 70 C, non-freezing.
This is a genuine AirTAC part from the G-series air-treatment line, which spans 200, 300, 400 and 600 sizes with a choice of ports, threads (PT standard, G and NPT as order options), drain types, filter grades and gauge scales. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing figures 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 0.05 - 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.

| 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.

Feeding clean, regulated air to the cylinders of a small stamping or clinching press, where the 5 um element protects valve spools and the check valve holds downstream pressure between strokes.
Conditioning the air feeding carton-sealing and wrapping machinery, where the manual-drain bowl is bled at shift start and the psi gauge lets operators set the working pressure at the machine.
Supplying a filtered, regulated branch to pneumatic sensors and control panels on a process line, with the 5 um grade guarding fine orifices and the check valve preventing backflow into the drop.
The 300 size with a 3/8 in port sits mid-range in the GFR family; step up to 400 or 600 or down to 200 depending on the flow your line needs, and match the thread to your piping (PT is the standard; G and NPT are order options). The 5 um element here suits downstream equipment that is sensitive to fine particulate; choose the 40 um standard grade where general protection is enough. Drain choice matters: manual drain (this unit) needs periodic bleeding, while automatic and differential-pressure drains discharge condensate without operator action. The embedded square gauge reads in psi; MPa and bar scales and an external round gauge are alternatives. This unit ships without a bracket, so plan your mounting accordingly. Because flow is published as curves rather than 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. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR300 series as curves rather than a single rated figure, so we do not quote one number. Tell us your inlet pressure and the flow your application needs, and we will confirm the sizing from the datasheet on request before you order.
The M in the code sets a manual drain: condensate collects in the polycarbonate bowl and must be bled off periodically, unlike the automatic or differential-pressure drain options. The W sets the 5 um filter element, one grade finer than the 40 um standard, for downstream equipment that needs cleaner air.
