The AirTAC GFR300C10MJC2TK AirTAC Filter Regulator NPT3/8 40 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 GFR300C10MJC2TK is an AirTAC GFR300 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration has a 3/8 in NPT port, a manual drain on the polycarbonate bowl, the standard 40 um filter element, a round pressure gauge reading in psi, and a built-in reverse (check) valve; it is supplied without a mounting bracket. 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 GFR family covers sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, a choice of drain (differential-pressure, automatic or manual), an optional 5 um element (code W), gauge and scale options, and G (BSPP) or NPT thread variants to order. Flow is published as curves rather than a single rating, so ask us to confirm the figures from the datasheet 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.

Feed clean, regulated air to the carton sealers and case erectors on a packaging line, with the built-in check valve holding downstream pressure through brief supply dips.
Regulate supply pressure to pneumatic clamps and tool-change cylinders on a CNC machining centre, with 40 um filtration protecting the directional valves.
Supply diverter gates and pusher cylinders on a sortation conveyor with regulated air; the manual drain suits a daily-check maintenance routine.
Size 300 with a 3/8 in NPT port sits mid-range in the GFR line; step between sizes 200, 300, 400 and 600 to match the port and flow path of your circuit. Drain: this unit is manual, so collected water is released by opening the drain valve - choose automatic or differential-pressure drain if the unit is hard to reach. The filter grade here is the standard 40 um element; specify code W for the 5 um option where finer filtration is needed. The round gauge on this unit reads in psi; the embedded square gauge and MPa or bar scales are the alternatives. Thread: PT is the AirTAC standard, with G (BSPP) and NPT as order options - this unit is ordered with NPT. Flow is published as curves, not a single rating, so 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 figure, so we do not quote a number here. Send us your application details and we will confirm the sizing from the AirTAC datasheet on request.
This unit carries code M, a manual drain: collected water is released by opening the drain valve by hand. If the regulator sits in a hard-to-reach position or the compressor runs unattended, order the automatic (A) or differential-pressure (blank) drain variant of the same model instead.
