The AirTAC GFR30010MJF2WT AirTAC Filter Regulator 3/8 in NPT 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 GFR30010MJF2WT is a 300-size GFR filter regulator: water and particulate filtration plus downstream pressure regulation in a single body. This configuration is built with 3/8 in NPT ports, a fine 5 um filter element (the W grade, against the 40 um standard), a manual drain on the PC bowl, an embedded square gauge reading in psi, and no mounting bracket. The standard regulator covers an adjustment range of 0.05-0.9 MPa (7-130 psi), and the unit handles a maximum inlet pressure of 1.0 MPa (145 psi) at temperatures from -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family is offered in sizes 200, 300, 400 and 600 with a choice of port sizes, PT/G/NPT threads, drain types, filter grades, gauge styles and scales, so a variant can be matched to most compressed-air drop points. Flow is published as curves rather than a single rated figure, so ask us to confirm sizing or any datasheet figure against 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.
| GFR300 | G-series filter regulator, 300 body — sets the port range. |
|---|---|
| 10 | Port size PT3/8". This body offers 08 = PT1/4", 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. |
| (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.

Filtered, regulated air for pneumatic cylinders on an assembly line: the 5 um element protects valve and cylinder seals from particulate and condensed water while the regulator holds a steady working pressure at the drop.
Supplying diverter and stopper actuators on a packaging conveyor, where a stable set pressure keeps indexing repeatable and the manual drain lets an operator clear condensate at shift checks.
A compact filter-regulator stage at the inlet of a machine's pneumatic panel, giving the OEM one body instead of two, with a square psi gauge the operator can read at the cabinet face.
Choose the size and port step against the air demand of the drop: this 300-size unit carries 3/8 in NPT ports, and larger sizes give larger ports and more flow. Pick the drain to suit attendance: manual (as here) needs someone to open the drain, automatic drains on their own schedule, and the differential-pressure default drains when the pressure drop calls for it. Pick the filter grade by cleanliness need: 40 um standard, 5 um (W) where finer protection matters. The embedded square gauge is standard (this one reads psi; MPa and bar scales exist) and an external round gauge is optional. PT is the standard thread; G and NPT are order options. A bracket can be added or omitted (this unit has none). Flow is published as curves, not a single rating, so ask us to confirm sizing against the 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 family as curves rather than a single rated figure, so we do not quote a l/min or SCFM number. Tell us your application and we will confirm the flow data from the datasheet so you can size the 300-size unit against your demand before ordering.
This unit's manual drain means condensate is released when an operator opens the drain, which suits attended lines with regular maintenance rounds. If the drop is unattended, the automatic drain option (code A) or the differential-pressure default drains without hands-on attention - just order the corresponding code.
