The AirTAC GFR300C15JF1TK AirTAC Filter Regulator NPT1/2 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 GFR300C15JF1TK is an AirTAC GFR300 filter regulator: filtration and pressure regulation combined in a single body. It removes water and particulate down to 40 um and holds your set downstream pressure anywhere in the 0.15-0.9 MPa (20-130 psi) adjustment range, with a maximum inlet pressure of 1.0 MPa (145 psi). This configuration is the size 300 unit with a 1/2 in NPT port, a differential-pressure drain that bleeds collected condensate automatically as flow passes through, the standard 40 um element, an embedded square gauge reading in MPa, and a reverse/check valve fitted to hold downstream pressure if the supply drops. The polycarbonate bowl suits the -5 to 70 C (non-freezing) operating range, and this code specifies no mounting bracket.
This is a genuine AirTAC part. The GFR series is available in sizes 200, 300, 400 and 600 with matching port sizes, a choice of differential-pressure, automatic or manual drain, an optional 5 um element (code W), gauge scales in MPa, psi or bar, and PT, G or NPT thread options. Flow figures are published as curves rather than a single rating, so ask us to confirm the datasheet 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.

Clean, regulated air for the stopper and pusher cylinders on a carton packaging line, with condensate knocked out before it reaches the valves at each drop.
Holding a consistent set pressure on clamp cylinders at a machining cell, with the check valve keeping clamps from venting if the main supply dips.
A point-of-use filter regulator at the header take-off feeding air tools and small actuators across a production floor, draining condensate as it flows.
Size and port step up together: 200, 300, 400 and 600 cover increasing port sizes and flow demand, so match the size to your line's air consumption - we can check the published flow curves against your requirement. Choose the drain to suit access: differential-pressure (this unit) drains itself in service, automatic drains on shut-down, and manual suits infrequently attended points; note the manual-drain variant widens the regulation range down to 0.05 MPa. The standard element is 40 um; specify W for 5 um where downstream equipment needs finer filtration. The embedded square gauge is MPa as coded here, with psi or bar scales and an external round gauge available. Thread is NPT on this code; PT (standard) and G are orderable options. Brackets are optional on GFR - this code omits one. 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.
AirTAC publishes flow for the GFR series as curves rather than a single rated figure, so there is no one l/min or SCFM number we can quote. Send us your air consumption and line pressure and we will confirm the sizing from the datasheet on request.
The differential-pressure drain bleeds collected condensate out automatically as air flows through, with no operator action. If your usage is intermittent, an automatic drain (code A) discharges on shut-down; a manual drain (code M) suits attended points and also widens the regulation range down to 0.05 MPa (7 psi).
