The AirTAC GFR300C10F2G AirTAC Filter Regulator G3/8 (3/8 in) 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 GFR300C10F2G is an AirTAC GFR-series filter regulator: water and particulate filtration plus downstream pressure regulation combined in a single body. This size-300 unit has a G3/8 (3/8 in) port, the standard 40 um filter element, a differential-pressure drain and a built-in square gauge reading in psi. The regulator adjusts from 0.15 to 0.9 MPa (20-130 psi), maximum inlet pressure is 1.0 MPa (145 psi), and the polycarbonate bowl suits ambient temperatures from -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, manual or automatic drain options, a 5 um filter grade (code W), MPa/psi/bar gauge scales, and G or NPT threads as order options. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures 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.

Feeding filtered, regulated air to tool changers, clamps and pneumatic cylinders on a machining cell supplied through a 3/8 in line, with the psi gauge giving operators a direct setpoint readout.
Conditioning the air feeding carton-sealer and case-packer cylinders, where the 40 um element removes water and particles before they reach the valves and the regulator holds a stable working pressure.
Supplying regulated air to diverters, stop gates and pushers on a bottling or distribution conveyor, with the differential-pressure drain handling accumulated condensate automatically during operation.
Size and port set the capacity: the 300 size with a 3/8 in port sits mid-range in the GFR line, so step up to 400 or 600 for higher demand or down to 200 for compact points of use. Drain type is a real choice: this unit uses the differential-pressure drain (the default), while automatic (A) and manual (M) drains are order options. Filtration is the standard 40 um element; specify W for the 5 um grade where finer particle capture is needed. The fitted square gauge reads psi, with MPa and bar scales as alternatives and an external round gauge optional.
Flow is published as curves, not a single rated figure, so send us your demand and we will confirm sizing against the datasheet before you order. The thread here is G (BSPP); PT is the standard and NPT is an order option. A mounting bracket is included with this configuration.
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.
Flow for the GFR300 series is published as curves rather than a single rated figure, so we do not quote a number here. Send us your line pressure, downstream demand and port size, and we will confirm the flow and the full datasheet figures for this unit on request.
F2 decodes as the fitted square gauge with a psi scale; MPa (1) and bar (3) scales are catalogue alternatives, and an external round gauge is optional. The rest of this code is the default configuration: differential-pressure drain, standard 40 um filter element, no reverse/check valve, and the mounting bracket included.
