The AirTAC GFR300C10JC2WK AirTAC Filter Regulator PT3/8, 5 um 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 GFR300C10JC2WK is an AirTAC GFR300 filter regulator: it removes water and particulate from compressed air and holds a regulated downstream pressure in a single body. This configuration is a 3/8 in PT port unit with a 5 um filter element (code W), a differential-pressure drain, an external round gauge reading psi, a built-in reverse (check) valve and no mounting bracket. Its regulation range is 0.15-0.9 MPa (20-130 psi), it accepts up to 1.0 MPa (145 psi) inlet, and it operates from -5 to 70 C (non-freezing). At size 300 the bowl is polycarbonate.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and offers drain, filter-grade, gauge-style and scale, thread (PT, G, NPT) and bracket options. Flow for this unit is published as curves rather than a single rating, so ask us to confirm sizing and 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.

Conditioning the air feeding pneumatic clamps and tool-change cylinders on a CNC lathe or machining centre, with the 5 um element protecting close-tolerance valves from water and particulate.
Supplying filtered, regulated air to diverter gates and stopper cylinders on a bottling or carton conveyor line, where the regulator holds a steady downstream setting through line start-stops.
Feeding pilot air to automated process valves on a filling or wash-down line, with the fitted check valve blocking reverse flow and the psi gauge giving operators a local pressure reading.
Size 300 with a PT3/8 port sits mid-range in the GFR line; step down to 200 or up to 400/600 depending on the air demand of your circuit - we can check the flow curves against your requirement. The 5 um element (code W) suits points of use that need cleaner air than the 40 um standard grade, and the differential-pressure drain bleeds the bowl automatically as air passes. The gauge on this version is an external round gauge reading psi; an embedded square gauge and MPa or bar scales are catalogue alternatives. Thread is PT as standard, with G (BSPP) and NPT available to order, and this unit is supplied without a mounting bracket. Ask us to confirm sizing against the flow 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 as curves rather than a single rated figure, so there is no one number we can quote. Tell us your working pressure and air demand and we will confirm the sizing from the datasheet on request.
The W in the code specifies the 5 um filter grade; the GFR300 standard grade is 40 um. Choose 5 um where downstream valves and cylinders need cleaner air, and 40 um for general plant air - both are catalogue options in this size.
