The AirTAC GFR300C10JF2G AirTAC Filter Regulator G3/8, 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 GFR300C10JF2G is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This size 300 unit has a G3/8 (BSPP) port, a 40 um filter element, a differential-pressure drain and an embedded square gauge scaled in psi. The regulator is the standard type with a 0.15-0.9 MPa (20-130 psi) setting range, maximum inlet pressure is 1.0 MPa (145 psi), and the operating temperature range is -5 to 70 C (non-freezing). The size 300 bowl is polycarbonate (PC), and no mounting bracket is fitted on this code.
This is a genuine AirTAC part. The GFR family is published in sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, and with choices of drain type, 40 um or 5 um (code W) filtration, gauge scale, thread (PT standard; G and NPT as order options) and bracket. 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.

Fitted at the air inlet of a CNC machining cell, this unit removes water and particulate ahead of the machine's solenoid valves and pneumatic actuators while holding a steady regulated supply pressure for clamping and tool-change functions.
Mounted on the drop feeding a packaging conveyor's pneumatic cylinders and grippers, it keeps contaminants out of the valves and gives the line operator a local, gauge-readable setting for consistent pick-and-place motion.
Installed ahead of the spray guns in an automotive paint booth, it strips water and particles from the air line and lets the painter dial in a stable atomizing pressure, read directly off the psi gauge.
Size and port step up together: 200, 300, 400 and 600 cover 1/8 to 1 inch, so choose the size whose flow curve covers your demand at your working pressure. On this code the drain is differential-pressure (the default), filtration is the 40 um standard element (5 um is code W), and the embedded square gauge is scaled in psi, with MPa and bar scales available as alternatives. The thread here is G (BSPP); PT is the standard thread and NPT is an order option, and no mounting bracket is fitted. Because flow is published as curves rather than a single rated figure, 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.
Flow for the GFR300 series is published as curves, not as a single rated number, so we do not quote a figure here. Tell us your working pressure and air demand and we will confirm the sizing from the AirTAC datasheet on request.
This code carries the differential-pressure drain, the default for GFR: it bleeds accumulated condensate from the bowl automatically whenever the pressure differential across the filter element is high enough. Automatic (code A) and manual (code M) drains are available as order options.
