The AirTAC GFR300C15JC2WT AirTAC Filter Regulator NPT1/2, 5 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 AirTAC GFR300C15JC2WT is a GFR300 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration has NPT1/2 ports, the optional 5 um filter element (code W, against the 40 um standard), a differential-pressure drain, a round pressure gauge reading in psi, a standard regulator, and no mounting bracket or reverse/check valve. Maximum inlet pressure is 1.0 MPa (145 psi), the setting range is 0.15-0.9 MPa (20-130 psi), and the operating temperature is -5 to 70 C, non-freezing. The bowl on this size 300 unit is polycarbonate; only size 600 uses an aluminium alloy bowl.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, and options include automatic or manual drains, the 5 um element, square or round gauges with MPa, psi or bar scales, and G (BSPP) or NPT threads in place of the PT standard. Flow is published as curves rather than a single rating, so ask us to confirm sizing and datasheet figures 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.

Clean, regulated air to pneumatic clamps and vises on a machining centre, holding workpiece pressure steady through the cutting cycle.
Air preparation for carton sealers and form-fill-seal machines, where the 5 um element helps protect directional valves from water and debris.
A filtered, regulated drop at the bench for air ratchets, die grinders and blow guns in a plant maintenance shop.
Pick the size and port by the air your line uses: sizes 200, 300, 400 and 600 step up in port and capacity, and this unit is size 300 with 1/2 inch NPT threads (PT is the AirTAC standard; G and NPT are order options). Drain comes as differential-pressure (this unit), automatic (A) or manual (M). Filter grade is 40 um standard or 5 um with W - this one carries the finer 5 um element. Gauges are an embedded square gauge as standard or an external round gauge in MPa, psi or bar scales; this configuration has a round psi gauge, and it is ordered without a bracket (J code). Because AirTAC publishes flow as curves rather than a single rated figure, 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 we do not quote one number. Tell us your line pressure and the air your application consumes, and we will confirm sizing from the datasheet on request.
The W in the code selects the optional 5 um element instead of the 40 um standard. It is the finer choice where pilot valves, gauges or instruments need cleaner air; both grades are available across the GFR range.
