The AirTAC GFR300C15AJC2 AirTAC Filter Regulator PT1/2, 40 um 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 GFR300C15AJC2 is an AirTAC GFR300 filter regulator: it removes water and particulate from compressed air and holds downstream pressure in one body. This configuration is built around a PT1/2 (1/2 in) PT-thread port, a 40 um standard filter element, an automatic drain that ejects collected condensate without operator attention, and a round pressure gauge reading in psi. The regulator is the standard type with a 0.15-0.9 MPa (20-130 psi) adjustment range, maximum inlet pressure is 1.0 MPa (145 psi), and the operating temperature window is -5 to 70 C (non-freezing). The bowl on this 300 size is polycarbonate, and no mounting bracket is included.
This is a genuine AirTAC part. The GFR series spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, drain choices (differential-pressure, automatic or manual), a 5 um optional element (code W), embedded square or external round gauges with MPa, psi or bar scales, and G or NPT thread options. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures 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.

Feeding filtered, regulated air to the cylinder circuit of a stamping press, where the 1/2 in port matches the plant air drop and the psi gauge lets setters verify working pressure at the machine.
Conditioning air for conveyor stoppers, pushers and diverters on a packaging line, with the automatic drain keeping condensate out of directional valves during continuous shifts.
Supplying clean, regulated air to pneumatic test benches and laboratory rigs, where the 40 um element protects sensitive instruments and the psi gauge supports repeatable test settings.
Choose the size by port and demand: this 300-size unit carries a PT1/2 port, so step up or down a size when your piping or air consumption differs. Drain type matters: the automatic drain here suits unattended duty, while manual and differential-pressure drains put discharge under operator or pressure-drop control. The filter grade is the 40 um standard; specify code W for the 5 um element when finer particulate control is needed. The fitted round gauge reads psi, with MPa and bar scales available as alternatives. Thread is PT as standard - G (BSPP) and NPT are order options - and this code omits the mounting bracket. 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 flow for the GFR300 as curves rather than a single rated figure, so there is no one flow number we can quote. Tell us your application and we will confirm the datasheet flow figures for this PT1/2 unit on request before you order.
The A in the code sets the automatic drain, which discharges collected condensate without operator attention - useful on unattended or continuous-duty lines. The same 300-size filter regulator is also available with a manual drain or the differential-pressure default; ask us for those codes.
