The AirTAC GFR30010MJF2T AirTAC Filter Regulator 3/8 in NPT is a genuine G-series filter regulator: water separation, 40 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 GFR30010MJF2T is a size-300 filter regulator: water and particulate filtration plus downstream pressure regulation combined in a single body. This configuration has a 3/8 in NPT port, the standard 40 um filter element, a manual-drain polycarbonate bowl, and a standard regulator adjustable from 0.05 to 0.9 MPa (7-130 psi). The embedded square gauge is fitted with a psi scale, no mounting bracket is included, and no reverse/check valve is fitted. 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 GFR series, which spans sizes 200, 300, 400 and 600 with a choice of port sizes, PT/G/NPT threads, drain types, 40 um or 5 um filtration, gauge scales and bracket options. Flow is published by AirTAC as curves rather than a single rated figure, so we 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.
| 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. |
| (blank) | Filtering grade 40 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.

Feeding filtered, regulated air to a bench-mounted pneumatic press or clamping fixture, where the operator sets working pressure once at the gauge and drains the bowl manually at shift checks.
Conditioning the air supply to conveyor diverters, baggers and carton-sealing cylinders, removing water and pipe scale before it reaches valves and actuators downstream.
Point-of-use air treatment on a CNC or assembly-machine drop from the plant ring main, protecting the machine's directional valves from condensate and debris at a set pressure.
Choose the size by the port and flow step you need: this unit is size 300 with a 3/8 in NPT port; step up to 400 or 600 for larger ports and flow, or down to 200 for smaller lines. Drain type is a real choice: manual drain (this unit, which also widens the regulation range to 0.05-0.9 MPa) versus automatic or differential-pressure drain. Filtration is 40 um standard; add code W for 5 um where finer particle capture is needed. Gauge scale can be MPa, psi or bar (this unit is psi), and the thread can be ordered as PT (standard), G (BSPP) or NPT. Because AirTAC publishes flow only as curves, 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 does not publish a single rated flow figure for this unit; flow is given only as performance curves. Tell us your line 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 means condensate collected in the polycarbonate bowl is released by hand rather than automatically, so the bowl needs periodic draining as part of maintenance. On this manual-drain configuration the regulation range is 0.05-0.9 MPa (7-130 psi), the wider range AirTAC specifies for manual-drain filter regulators.
