The AirTAC GFR300C10MC2WGK AirTAC Filter Regulator G3/8, 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 GFR300C10MC2WGK is a GFR-series filter regulator: one body that removes water and particulate from compressed air and then regulates downstream pressure. This 300-size unit is threaded G3/8 (BSPP), carries a 5 um filter element (code W), a manual drain and a metal bowl. The standard regulator covers 0.05-0.9 MPa (7-130 psi), maximum inlet pressure is 1.0 MPa (145 psi), and the operating temperature range is -5 to 70 C (non-freezing). It is fitted with an external round gauge reading in psi, a reverse (check) valve and a mounting bracket.
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 that include 40 um or 5 um filtration, differential-pressure, automatic or manual drains, embedded square or external round gauges (MPa, psi or bar scales), G or NPT threads in place of the PT standard, and a check valve. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet and sizing 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.

Feeding filtered, regulated air to the valves and actuators on a CNC machining centre: the 5 um element screens particles before the machine's directional valves, the regulator holds the set pressure to the actuators, and the manual drain is opened during scheduled maintenance to clear collected water.
Supplying regulated air to the cylinders and grippers that form, fill and seal cartons on a packaging line. The G3/8 ports suit the line's main drop, the check valve is fitted on the regulator, and the psi gauge lets the line technician read and lock the working pressure at the station.
Conditioning air at a spray booth or finishing bench: the 5 um element reduces particulate ahead of the spray gun, the regulator sets the gun supply pressure, and the round psi gauge gives the operator a direct reading at the point of use.
The real, decodable choices on a GFR unit are: size and port (200/300/400/600; 1/8 to 1 inch) matched to the air your line needs; drain type - differential-pressure as standard, automatic, or manual as on this model (manual also allows setting down to 0.05 MPa, while automatic and differential-pressure drains set from 0.15 MPa); filter grade, 40 um standard or 5 um with code W as fitted here; gauge - embedded square as standard, external round optional, in MPa, psi or bar (this model is a round psi gauge); thread, PT as the standard with G or NPT to order (this model is G); bracket; and the K check-valve option. Flow is published as curves, not a single rated figure, so send us your application details 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 GFR300 flow as curves rather than a single rated figure, so we do not quote a number here. Send us your application details - port size, downstream demand and working pressure - and we will confirm the flow and sizing from the datasheet on request.
Code M means a manual drain: you open it during scheduled checks to expel the water collected in the bowl. If the unit will sit where regular access is awkward, the same GFR300 size can be ordered with an automatic or differential-pressure drain instead; note that those versions regulate from 0.15 MPa, while this manual-drain model sets from 0.05 MPa (7-130 psi).
