The AirTAC GFR300C15AC1TK 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 AirTAC GFR300C15AC1TK is a size 300 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is built with a 1/2 in NPT port, an automatic drain that expels collected condensate without manual attention, a 40 um standard filter element, a round pressure gauge with an MPa scale, and a reverse (check) valve fitted. The maximum inlet pressure is 1.0 MPa (145 psi), the standard regulator adjustment range is 0.15-0.9 MPa (20-130 psi), and the operating temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR series is available in sizes 200, 300, 400 and 600 with a choice of ports, PT, G (BSPP) or NPT threads, differential-pressure, automatic or manual drains, a 40 um standard or 5 um (W) filter grade, embedded square or external round gauges with MPa, psi or bar scales, and an optional reverse valve. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

Feeding a pneumatic press station from a plant air main, this unit strips water and pipe scale from the supply and holds a steady regulated pressure so the press cylinder strokes consistently through each shift.
On a packaging line driving conveyor diverters and clamp cylinders, the filter regulator keeps moisture and debris out of the valves while giving the line setter one point to set and read the working pressure on the MPa gauge.
In an OEM machine's air preparation panel, the size 300 body with automatic drain and check valve provides filtered, regulated air to the machine's valve manifold, with the included bracket securing the unit to the panel plate.
Size 300 with a 1/2 in port suits lines whose required flow sits in the middle of the GFR range; step up to size 400 or 600 for higher demand or step down to size 200 for compact circuits, matching the published flow curve to your consumption rather than a single rating. The automatic drain on this unit suits unattended duty; choose manual drain where you prefer controlled blowdown, or the differential-pressure default where drain timing should follow loading. The 40 um element is the standard grade; specify the 5 um (W) option where downstream equipment needs finer filtration. The round MPa gauge is fitted here; square embedded gauges and psi or bar scales are alternatives, and PT is the standard thread with G (BSPP) and NPT as order options. A bracket is included for mounting. Because flow is published as curves, not a single rating, 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 GFR flow as curves rather than a single rated figure, so we do not quote one number. Send us your line pressure, working pressure and air consumption, and we will confirm the flow data from the datasheet and check the sizing for your application before you order.
The A in the code GFR300C15AC1TK means the bowl drain is automatic, so collected condensate is expelled without anyone opening the drain. GFR300 units can also be ordered with a manual drain or with the differential-pressure drain as the default, and the regulation range depends on that choice: 0.15-0.9 MPa (20-130 psi) with automatic or differential-pressure drain, or 0.05-0.9 MPa (7-130 psi) with manual drain.
