The AirTAC GFR300C10MJC2G AirTAC Filter Regulator G3/8 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 See datasheet ports, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The AirTAC GFR300C10MJC2G is a filter regulator: it removes water and particulate from compressed air and holds the downstream pressure at your setpoint, all in one body. This 300-size unit is threaded G3/8, uses a 40 um filter element, drains by hand through its manual drain, and carries a round pressure gauge reading in psi. The standard regulator covers 0.05-0.9 MPa (7-130 psi) and maximum inlet pressure is 1.0 MPa (145 psi). The metal bowl suits ambient temperatures from -5 to 70 C (non-freezing); no reverse (check) valve is fitted and no mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, and can be ordered with manual, automatic or differential-pressure drains, a 5 um element (code W), an embedded square gauge or an external round gauge in MPa, psi or bar scales, G or NPT threads, and bracket options. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing for your application.

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 0.15 - 0.9 MPa (20 - 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.

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.

Feeds clean, regulated air to pneumatic clamps and tool-change cylinders on a CNC machining centre, with the manual drain letting maintenance drain accumulated water at shift start.
Sits at the drop of a carton packaging conveyor to condition and regulate air for stoppers, pushers and reject cylinders, with the psi gauge giving operators a local setpoint check.
Conditions and regulates the supply to gripper and clamp actuators on a robotic palletising cell, where a stable setpoint keeps grip force consistent across the shift.
Choose the size by required flow: 200, 300, 400 and 600 step up in port and capacity, and this 300 unit sits at G3/8. Drain type is a real choice on GFR: manual (this unit, which widens the regulation range to 0.05-0.9 MPa), automatic, or the differential-pressure default. Filter grade is 40 um standard or 5 um with code W. On gauges, the embedded square gauge is standard and external round gauges are optional in MPa, psi or bar scales - this unit carries a round psi gauge. Thread: PT is the standard; G and NPT are catalogue options to order. Brackets can be included or omitted (this unit has none). Flow is published as curves, not a single rating, so send us your flow and pressure requirements and we will confirm sizing against the datasheet before you order.
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 GFR300 flow as performance curves rather than a single rated figure, so we do not quote a number here. Send us your flow, inlet pressure and setpoint and we will confirm the datasheet figures and check the sizing for your application before you order.
The M in the code selects a manual drain: the bowl is drained by hand, and on manual-drain units the regulation range is 0.05-0.9 MPa (7-130 psi). The C2 code selects the external round gauge with a psi scale; the embedded square gauge is the standard alternative, with MPa, psi or bar scales available.
