The AirTAC AirTAC GFR300C15AC2WGK Filter Regulator G1/2 1/2 in 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 GFR300C15AC2WGK is a size-300 filter regulator: water and particulate filtration plus downstream pressure regulation combined in one body, so a single 1/2 in (G1/2, BSPP) connection does both jobs. This configuration carries the 5 um element (code W) for finer particle removal than the standard 40 um grade, an automatic drain that bleeds collected condensate without manual attention, a round external gauge reading in psi, a built-in reverse/check valve that holds the downstream setting if upstream supply is interrupted, and a mounting bracket. 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 is -5 to 70 C, non-freezing.
This is a genuine AirTAC part from the G-series filter-regulator line, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of automatic, manual or differential-pressure drain, 40 um or 5 um filtration, gauge scale options, and PT, G or NPT threads. We confirm flow and full datasheet figures on request - flow is published as curves rather than a single rating - so ask us before ordering if you need sizing data.

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 fixture clamps and tool-change cylinders on a machining centre, with the 5 um element keeping fine particles out of the clamp circuit and the check valve holding clamp pressure if shop supply dips.
Point-of-use conditioning ahead of spray booths and air-driven paint equipment, where the 5 um grade and automatic drain protect finish quality without an operator draining bowls each shift.
Filtered, regulated air for carton-forming and case-packing cylinders on a packaging conveyor, with the psi gauge letting line technicians set and verify the actuator pressure at a glance.
Choose the size step (200/300/400/600) against the flow your line needs, then match the port - this unit is the 300 size with G1/2 (1/2 in) thread; PT is the catalogue standard and G/NPT are order options. Pick the drain to suit access: automatic (as here) where the unit is mounted where nobody passes, manual where you want positive control, or the differential-pressure default. Pick 40 um for general protection or 5 um (code W, as fitted here) for finer filtration ahead of sensitive components. Select the gauge scale (MPa, psi or bar) and round vs embedded square style, and add a bracket if the unit will be wall- or panel-mounted rather than screwed directly into the manifold. Flow for this family is published as curves, not a single rated figure, so send us your application conditions and we will confirm the 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 filter-regulator flow as performance curves rather than a single rated figure, so we do not quote a l/min, m3/h or SCFM number. Tell us your line pressure and the flow your equipment needs and we will confirm the sizing against the datasheet on request.
Both are decodable from the code: A in the drain position selects the automatic drain, which expels collected condensate on its own instead of relying on the differential-pressure default or manual draining, and W selects the 5 um filter grade instead of the 40 um standard. Choose 5 um where downstream components are sensitive to finer particles; choose 40 um for general-purpose protection.
