The AirTAC GFR300C10JC2T AirTAC Filter Regulator NPT 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 AirTAC GFR300C10JC2T is a filter regulator: it removes water and particulate from compressed air and sets downstream pressure in a single body. This size 300 unit is threaded NPT 3/8 in, carries the standard 40 um filter element, and drains condensate by differential pressure, so the bowl purges as the pressure differential across the element builds. The outlet pressure is set anywhere in the 0.15-0.9 MPa (20-130 psi) range, and this configuration is fitted with an external round gauge reading in psi. The polycarbonate bowl suits the -5 to 70 C (non-freezing) operating range, maximum inlet pressure is 1.0 MPa (145 psi), and this code specifies no mounting bracket and no reverse/check valve.
This is a genuine AirTAC part. The GFR filter-regulator line spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and options include automatic or manual drains, a 5 um element (code W), alternative gauge scales in MPa or bar, G (BSPP) or NPT threads, 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.

Filtered, regulated air feeding clamping cylinders on a machining centre fixture, where the 40 um element protects the clamp valve and the psi gauge lets the setter verify clamp pressure at the panel.
Point-of-use supply for carton sealing and case-erector cylinders on a packaging conveyor, with the differential-pressure drain clearing condensate through each shift without operator attention.
A wall-mounted drop feeding air tools and blow-off guns in a fabrication shop, where the regulator holds a steady working pressure and the 40 um element keeps rust and pipe scale out of the tools.
Size 300 with a 3/8 in NPT port sits in the middle of the GFR range; step up to size 400/600 or down to 200 depending on the flow your line needs, and confirm the choice against the published flow curves rather than a single rating. Drain choice matters: differential-pressure (this unit) purges automatically under load, automatic (code A) drains on a timer-free cycle, and manual (code M) needs an operator. The standard element is 40 um; specify W for 5 um where finer filtration is required. Gauge options are the embedded square gauge or an external round gauge, scaled in MPa, psi or bar - this code carries a round psi gauge. Threads are PT as standard with G (BSPP) and NPT as orderable options; a bracket can be added if the code omits it (J means no bracket). We confirm sizing against the published curves on request 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 number, so we do not quote a figure here. Tell us your application and we will confirm the datasheet flow curve and check the sizing against your required flow before you order.
C specifies an external round gauge and 2 sets its scale to psi. The embedded square gauge is the standard alternative, and scales in MPa (code 1) or bar (code 3) are available - just order the corresponding code in the same size and thread.
