The AirTAC GFR30010MJC2T AirTAC Filter Regulator NPT3/8, 40 um 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 GFR30010MJC2T is an AirTAC GFR300 filter regulator: filtration and pressure regulation combined in a single body. It removes water and particulate from compressed air with a 40 um element and holds your set downstream pressure, with a regulation range of 0.05-0.9 MPa (7-130 psi). This configuration is a 300-size unit with a 3/8 in NPT port, a manual drain for the polycarbonate bowl, a fitted external round gauge reading in psi, and no mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family is available in 200, 300, 400 and 600 sizes with a choice of ports, threads (PT standard; G and NPT as order options), drain types, filter grades (40 um standard, 5 um with code W) and gauge styles and scales. Flow figures are published as curves rather than a single rating, so ask us to confirm the datasheet and sizing 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.

|---|---|
| 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. |

| C | Gauge shape: Round. 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. |

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.

Conditioning the air feeding tool-clamp and pallet-change cylinders on a CNC machining centre: the 40 um element strips water and swarf-laden particulate before it reaches the clamping valves, while the regulator holds a steady set pressure for repeatable clamping.
Supplying cleaned, regulated air to the stopper cylinders, diverters and lift gates on a packaging conveyor line, where the manual drain suits a line that is bled down at shift change and the psi gauge lets operators verify set pressure at a glance.
Feeding the air cylinders that index bottles through a rinse-and-fill station, where the filter-regulator in one body saves panel space and the polycarbonate bowl with manual drain keeps condensed water out of the filling heads.
Choose the GFR300 size step when your line runs around a 3/8 in port; smaller 200 or larger 400/600 sizes shift the port and the flow band, so match the size to the air demand of the circuit. Drain type is a real choice: this unit has a manual drain, which suits attended installations where an operator can bleed the bowl; automatic or differential-pressure drains suit unattended lines. The 40 um element fitted here is the standard grade; specify 5 um (code W) where finer particulate removal is needed. The round gauge on this unit reads in psi; embedded square gauges and MPa/psi/bar scales are the other options. Thread is NPT here; PT is the catalogue standard and G is also orderable. A mounting bracket is optional (this unit 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. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR300 as curves rather than a single rated figure, so we do not quote a rated flow number. Send us your application details and we will confirm the flow and sizing from the datasheet on request before you order.
This configuration is coded M for a manual drain: the polycarbonate bowl is bled by hand, which suits attended installations. AirTAC also offers automatic (code A) and differential-pressure (blank) drains on the GFR family if your line runs unattended.
