The AirTAC AirTAC GFR300C15AF2WGK Filter Regulator 1/2 in, 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 GFR300C15AF2WGK is an AirTAC GFR300 filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This configuration is built around a G1/2 (BSPP) port, a 5 um filter element (grade code W), an automatic drain that ejects collected condensate without manual attention, and an embedded square gauge reading in psi. A reverse/check valve is fitted, the mounting bracket is included, and the polycarbonate bowl suits the size-300 body. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulator adjusts from 0.15-0.9 MPa (20-130 psi), and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR filter-regulator family spans sizes 200, 300, 400 and 600 with a choice of ports, threads, drain types, filter grades and gauge scales, so a variant can be matched to most point-of-use air-preparation duties. Flow is published as curves rather than a single rating, so ask us and we will confirm the datasheet figures for your application on request.

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 for tool-clamp cylinders and pneumatic actuators on a CNC machining centre, with the 5 um element protecting directional valves from particles and the automatic drain handling condensate at an unattended point of use.
Point-of-use preparation ahead of the cylinders and air jets on a carton-sealing or wrapping line: the regulator holds a steady setting for consistent case handling while the psi gauge gives operators a local reading.
Filtered, regulated air for pick-and-place grippers and screwdriver feeders at an assembly station, where the check valve helps hold the downstream circuit and the automatic drain suits a cabinet-mounted installation.
Start with the size and port: the GFR300 steps up from the 200 series with a larger port, so pick the size whose flow curve covers your demand with margin - we will confirm the curve against your consumption before you order. This unit already carries the 5 um element; the family default is 40 um, so choose 5 um where downstream valves and cylinders need finer protection. Drain type is a real decision: automatic (as fitted here) suits unattended or hard-to-reach installations, while manual and differential-pressure drains are the alternatives. Gauge scale (MPa, psi or bar), thread (PT is the standard; G and NPT are order options) and the bracket are the remaining decodable choices.
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 GFR300 flow as curves, not as a single rated figure, so we do not quote a number here. Send us your working pressure and air consumption and we will confirm the flow from the datasheet curve on request before you order.
The W in the code specifies the 5 um element instead of the 40 um standard, giving finer protection for downstream valves and cylinders. The A specifies the automatic drain, which expels collected condensate on its own - useful where the unit is mounted out of reach or the line runs unattended.
