The AirTAC GFR300C15AJC1TK 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 GFR300C15AJC1TK is an AirTAC GFR300 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is the 300 size with a 1/2 in NPT thread, a 40 um standard filter element, an automatic drain that discharges collected condensate without manual attention, a standard regulator with a 0.15-0.9 MPa (20-130 psi) adjustment range, an external round gauge on the MPa scale, a built-in reverse (check) valve, and no mounting bracket.
This is a genuine AirTAC part. The GFR series is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and with choices of drain type, filter grade (40 um standard or 5 um with code W), gauge style and scale, thread type (PT standard, G or NPT to order) and bracket. Flow is published as curves rather than a single rating, so we confirm datasheet figures on request.

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.

Installed at the point of use on a factory air drop, it cleans water and debris out of the supply and holds a steady regulated pressure to the cell's pneumatic tools and actuators.
Feeding cylinders and grippers on a packaging or conveyor line, it keeps condensed water out of the valves while the regulator holds consistent cylinder pressure for repeatable indexing.
Mounted in a machine's pneumatic supply panel ahead of directional valves and air cylinders, it combines filtration and regulation in one body, with the check valve holding the downstream setting if upstream pressure dips.
Choose the GFR300 size when your line runs at roughly 1/2 in porting and your required flow sits in the 300-size band; step up to 400 or 600 for higher demand, or down to 200 for smaller circuits. This unit already carries the automatic drain (code A), the 40 um standard element, the round MPa gauge (C1) and the reverse valve (K); if you need 5 um filtration, a different gauge scale (psi or bar), a square embedded gauge, or a G or PT thread instead of NPT, those are decodable options in the series. Note that code J means no mounting bracket is supplied, so plan your panel or manifold fixing accordingly. Flow for this series is published as curves, not a single rated figure, 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 no single flow number is quoted here. Tell us your line pressure and demand and we will confirm the sizing from the datasheet on request.
C means an external round gauge is fitted and 1 sets its scale to MPa (psi and bar are alternative scale codes). K means a reverse (check) valve is built in, which holds the regulated downstream pressure if upstream supply pressure drops.
