The AirTAC GFR300C15AF2TK 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 GFR300C15AF2TK 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 built around a 1/2 in NPT port, an automatic drain that expels collected condensate without a manual drain round, a 40 um standard filter element, and an embedded square gauge reading in psi. A reverse/check valve is fitted (code K), the regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), maximum inlet pressure is 1.0 MPa (145 psi), and the operating temperature range is -5 to 70 C (non-freezing). The bowl on this size 300 unit is polycarbonate (PC).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and options across the range include manual or differential-pressure drains, a 5 um (W) filter element, gauge scale choices, G (BSPP) or NPT threads, and bracket variations. Flow for G-series units is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

Supplying clean, regulated air to the cylinder valves of a stamping or forming press, with the psi gauge giving operators a setpoint they can read at the machine.
Feeding gripper and clamp cylinders on a carton-sealing or filling line, where the automatic drain clears collected condensate without a manual drain round.
A point-of-use filter regulator at an assembly cell air drop, combining water and particulate removal with a locally adjustable downstream pressure.
Size 300 with a 1/2 in NPT port sits mid-range in the GFR family, which steps from size 200 (1/8 and 1/4 in ports) through 400 up to size 600 (3/4 and 1 in); choose the size whose flow curve covers your demand rather than the port alone. Drain choices in the family are automatic (this unit), manual (M) and differential-pressure (blank); the filter element is 40 um as standard with a 5 um (W) option where finer filtration is needed. The embedded square gauge on this unit reads in psi, with MPa and bar scales selectable, and G (BSPP) or NPT threads can be ordered where PT is the standard. 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 G-series flow as curves, not as a single rated number, so we do not quote a figure. Send us your application details and we will confirm the flow curve and sizing from the datasheet on request.
The A code specifies an automatic drain, which expels condensate collected in the bowl without a manual drain routine. Manual (M) and differential-pressure (blank) drain versions are available in the same GFR family if you prefer a different arrangement.
