The AirTAC GFR300C15JC2G AirTAC Filter Regulator G1/2, 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 AirTAC GFR300C15JC2G is a 300-size filter regulator that cleans compressed air and holds downstream pressure in one body. Filtration removes water and particulate down to 40 um through the standard element, while the regulator holds your set pressure anywhere in the 0.15-0.9 MPa (20-130 psi) range. This configuration is threaded G1/2 (1/2 in), uses the differential-pressure drain that bleeds accumulated condensate automatically as flow passes through, and is fitted with an external round gauge reading in psi so operators can check and adjust the setting at a glance. No mounting bracket is included and no reverse/check valve is fitted.
This is a genuine AirTAC part. The GFR line runs from size 200 to 600 with port options from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drain, a 5 um element (code W) where finer filtration is needed, square or round gauges in MPa, psi or bar scales, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

Feeding a workshop pneumatic press or clamping station: the 40 um element strips water and pipe scale before the air reaches valves and cylinders, while the regulator holds a steady working pressure so cycle force stays consistent from stroke to stroke.
Supplying gated conveyors, case sealers and carton-closing cylinders on a packaging line: the G1/2 port suits a main drop leg, the differential-pressure drain keeps condensate moving out during production, and the psi gauge lets line staff verify the set point without tools.
Mounted ahead of a bank of directional valves or a pneumatic actuator panel: the regulator holds the pressure the valve manufacturer specifies, the 40 um grade protects spool clearances from particulate, and the round psi gauge gives a visible reference during commissioning.
Start with the port step: this unit is G1/2 (1/2 in) on the 300-size body, so match it to your line size and confirm the flow curve covers your demand - we can check the curve against your consumption on request. Choose the drain to suit access: differential-pressure (this unit) drains itself in service, automatic drains on a cycle, and manual suits infrequently attended points. Filtration is 40 um standard; specify the 5 um W grade only where downstream equipment needs finer air. Gauge options are the embedded square type or an external round gauge in MPa, psi or bar scales - this unit carries a round psi gauge. Thread is G here, with PT (standard) and NPT available to order, and a bracket can be added where the J no-bracket option does not suit the mounting. Because flow is published as curves rather than 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 publishes GFR flow as curves, not as a single rated figure, so we do not quote a l/min or SCFM number here. Send us your line pressure, set pressure and air consumption, and we will confirm the flow curve and sizing from the datasheet for your application before you order.
The differential-pressure drain on this GFR300 uses the airflow itself to discharge collected condensate, so it works continuously in service without attention. If the unit sits on a line with intermittent or very low flow, an automatic drain (code A) or a manual drain (code M) that you operate on a schedule may suit better - both are orderable options on the same series.
