The AirTAC AirTAC GFR300C15JC2 Filter Regulator 1/2 in PT, 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 GFR300C15JC2 is an AirTAC GFR300 filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This configuration is the size 300 unit with PT1/2 (1/2 in) ports, a 40 um standard filter element, and the differential-pressure drain, which auto-drains the polycarbonate bowl as flow conditions change. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), and the code specifies an external round gauge reading in psi instead of the embedded square gauge. No mounting bracket is included with this version and no reverse/check valve is fitted. 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 GFR300 sits in a family offered in sizes 200, 300, 400 and 600, with options that include automatic or manual drains, a 5 um element (code W), gauge scales in MPa, psi or bar, G or NPT threads in place of the PT standard, and a mounting bracket. Flow is published as curves rather than a single rated figure, 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.

Filter and regulate the shop-air feed to a CNC machine tool's pneumatic circuits, keeping water and particulate out of directional valves while holding a steady set pressure to clamps and actuators.
Feed the pick-and-place, clamp and eject cylinders on a packaging conveyor with clean, regulated air so grippers and clamps cycle at the line's set pressure without moisture carryover.
Supply a bench-top spray or coating station with filtered, regulated air so the nozzle sees a stable pressure and the supply stays free of water and particulate that would spoil the finish.
Step up or down through the GFR sizes (200/300/400/600) to match the port and flow path your line needs; this unit is the size 300 with PT1/2 (1/2 in) PT-thread ports. Choose the drain to suit maintenance access: differential-pressure (as coded here), automatic (A), or manual (M). The 40 um element is standard; specify the W code if the application needs 5 um filtration. The C2 code in this model fits the external round gauge with a psi scale; the embedded square gauge with MPa, psi or bar scales is the alternative. PT is the standard thread, with G (BSPP) and NPT available as order options, and the J code means no mounting bracket is supplied - order the bracket version if you need panel or wall fixing.
Flow for this series is published as curves, not a single rated number, so we cannot quote one honestly here. Send us your application details and we will confirm the sizing against the datasheet curves 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 flow for the GFR300 series as curves, not as a single rated figure, so there is no honest one-number answer to quote. Tell us your application - inlet pressure, set pressure and the equipment downstream - and we will confirm the flow from the datasheet curves on request before you order.
The C means this unit carries the optional external round gauge instead of the embedded square gauge, and the 2 sets its scale to psi. If you prefer the embedded square gauge, it is the standard fitting and can be ordered with MPa, psi or bar scales - just ask for the matching code.
