The AirTAC GFR300C15LC2WG AirTAC Filter Regulator, G1/2, 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.
GFR300C15LC2WG is an AirTAC GFR300 filter regulator: one body that removes water and particulate from compressed air and regulates the downstream pressure. This configuration carries a G1/2 (BSPP) port, the finer 5 um filter element (W grade, against the 40 um standard), a differential-pressure drain, the low-pressure regulator type, a round gauge scaled in psi, and a mounting bracket; no reverse/check valve is fitted. The bowl on this unit is metal.
It is a genuine AirTAC part, one of the GFR filter-regulator line in sizes 200, 300, 400 and 600, with port, thread (PT standard; G and NPT orderable), drain, filter grade, gauge and scale options. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. 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.

Feeding clean, regulated low-pressure air to spray guns in an automotive refinish booth, where the 5 um element keeps moisture and grit out of the finish.
Regulating clamping pressure on pneumatic fixtures at a machining centre, with the low-pressure type matched to the lower set pressures a clamping line runs at.
Supplying filtered, regulated air to the cylinder-driven flaps and pushers on a packaging conveyor, with the psi gauge letting line staff check set pressure at a glance.
Choose the size and port against the air your line actually uses: 300 sits mid-range in the GFR line, and this unit already carries the 1/2 in G-thread port. If your demand sits near the top of a size, step up to 400 or 600 rather than guessing. This code specifies the 5 um element - keep it where downstream valves, cylinders or instruments need cleaner air, and use the 40 um standard where general plant air is enough. Drain is differential-pressure here; automatic (A) and manual (M) versions exist if you prefer hands-off or scheduled draining. The round gauge is scaled in psi; the embedded square gauge and MPa or bar scales are the other catalogue choices. Thread is G (BSPP) on this code, with PT standard and NPT orderable. Flow is published as curves, not a single rating, so send us your application 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 GFR flow as curves rather than a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the flow and the full datasheet figures on request before you order.
The W in this model code selects the finer 5 um grade, which suits downstream valves, cylinders and instruments that need cleaner air than general plant service. If your application only needs standard filtration, the 40 um version of the same GFR300 unit is the usual choice - we can confirm either on request.
