The AirTAC GFR300C15LC2TK 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 GFR300C15LC2TK is an AirTAC GFR-series filter regulator: one body that first removes water and particulate from compressed air, then regulates the downstream pressure. This size 300 unit comes with a 1/2 in NPT port, the standard 40 um filter element, a differential-pressure drain, the low-pressure regulator type, an external round gauge reading in psi, a fitted reverse/check valve, a metal bowl and 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 is offered in sizes 200, 300, 400 and 600 with a choice of port, thread (PT standard; G and NPT are order options), drain type (differential-pressure, automatic or manual), filter grade (40 um standard, 5 um with code W), gauge style and scale, low-pressure type and reverse/check valve. Flow is published as curves rather than a single rating, so ask us to confirm sizing and any datasheet figure 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.

Point-of-use supply for the low-pressure air cylinders on a carton-sealing machine: the 40 um element strips water and pipe scale ahead of the valve bank, while the low-pressure regulator holds the light setting the sealing arms are set up for.
Filtered, regulated air for paint spray guns in a finishing booth. The low-pressure type suits atomising circuits that run below standard line settings, and the round psi gauge lets the operator read the working pressure directly in psi.
Supplies filtered, regulated pilot air to the pneumatic actuators on a water-treatment skid: the 40 um element protects the pilot valves, the differential-pressure drain clears collected condensate as air passes, and the round psi gauge gives operators a direct readout at the skid.
Choose the size by port and flow: sizes 200, 300, 400 and 600 step up in port and capacity, and this unit sits at size 300 with a 1/2 in NPT port. The decodable choices on this configuration are the low-pressure regulator type, the 40 um standard element (5 um is code W), the differential-pressure drain (automatic and manual are the alternatives), the external round psi gauge, the fitted reverse/check valve and the included bracket; PT is the standard thread with G and NPT available to order. Flow is published as curves, not as a single rating, so send us your application conditions and we will confirm sizing against the datasheet 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 GFR series as curves, not as a single rated figure, so we do not quote a number here. Send us your inlet pressure, set pressure and expected air demand, and we will confirm the flow from the datasheet for this exact model before you order.
It marks the low-pressure regulator type: this unit is built to regulate circuits that are set below the standard GFR range. The exact setting range for the low-pressure type is not published in our data, so we confirm it on request. Everything else in the decode is unchanged: 40 um element, differential-pressure drain, round psi gauge, fitted reverse/check valve, metal bowl, bracket, and the NPT1/2 port.
