The AirTAC GFR300C10JC2G AirTAC Filter Regulator G3/8 Round Psi Gauge 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 GFR300C10JC2G is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and holds downstream pressure at your setpoint in a single body. This size 300 unit comes with a G3/8 (BSPP) port, a 40 um filter element, a differential-pressure drain, and a round pressure gauge reading in psi. The regulator is the standard type with a 0.15-0.9 MPa (20-130 psi) adjustment range, maximum inlet pressure is 1.0 MPa (145 psi), and the polycarbonate bowl suits ambient temperatures from -5 to 70 C (non-freezing). No mounting bracket is included with this configuration.
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 options include manual or automatic drains, a 5 um element (code W), embedded square or external round gauges with MPa, psi or bar scales, G or NPT threads, a reverse/check valve, and a mounting bracket. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures for 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 0.15 - 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.

Point-of-use conditioning for a carton-sealer's directional valve manifold: the 40 um element strips water and pipe scale before it reaches the valves, while the regulator holds a steady setpoint so cylinder strokes stay consistent shift after shift.
Feeding pneumatic clamp cylinders on a machining cell: the G3/8 port suits a cell drop line, and the round psi gauge lets the operator verify clamp pressure at a glance without adding a separate gauge to the drop.
Conditioning air for diverter and stopper actuators along a bottling conveyor: the differential-pressure drain handles condensate during long continuous runs, and the regulator keeps diverter speed repeatable by holding a fixed supply pressure.
Step up or down by size and port: this unit is size 300 with a G3/8 port; larger sizes (400, 600) suit heavier demand and smaller sizes (200) lighter duty. Drain choice is real: differential-pressure (this unit, which bleeds condensate automatically under flow), automatic (code A) or manual (code M). The 40 um element is standard; specify code W for 5 um filtration. Gauges: the embedded square gauge is the standard fitting, with external round gauges in MPa, psi or bar scales as options - this unit carries the round gauge on a psi scale. Thread here is G (BSPP); PT is the standard thread and G/NPT are order options. No bracket is fitted (code J); choose the bracket variant if you need panel mounting. 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, not a single rated figure, so we do not quote a number here. Send us your line pressure, setpoint and expected air consumption, and we will confirm the datasheet curve against your application before you order.
The embedded square gauge is the standard fitting on GFR units. In this model code, C specifies the optional external round gauge and the 2 sets its scale to psi. Square-gauge variants and MPa or bar scales are available in the same family if you prefer them.
