The AirTAC GFR300C10AC2WGK 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 GFR300C10AC2WGK is an AirTAC GFR300 filter regulator: it removes water and particulate from compressed air and holds downstream pressure at your setpoint in a single body. This configuration is built on a 3/8 in port with G (BSPP) thread, carries the finer 5 um filter element, an automatic drain that discharges collected condensate without manual bleeding, a round pressure gauge reading in psi, a fitted reverse (check) valve, and the mounting bracket included. The bowl on this 300 size is polycarbonate; only the 600 size uses an aluminium alloy bowl.
It is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, filter grades of 40 um standard and 5 um optional (code W), differential-pressure, automatic or manual drains, embedded square or external round gauges in MPa, psi or bar scales, and PT, G or NPT threads (PT is the standard; G and NPT are order 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 figures from the datasheet 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.

Point-of-use filter regulator ahead of the tool-clamp and tool-changer cylinders on a machining center, holding a steady working pressure while the 5 um element keeps fines and condensate out of the clamp circuit.
Regulating the air feeding stopper, reject and pusher cylinders along a bottling conveyor, with the automatic drain clearing collected condensate through humid summer shifts without manual bleeding.
Supplying regulated air to pneumatic grippers and slides on a bench-top pick-and-place rig, where the round psi gauge makes setpoint checks quick during changeovers.
Size and port step up from 200 to 600 as air demand grows; this unit sits at size 300 with a 3/8 in G-thread port. The regulation range for this automatic-drain configuration is 0.15-0.9 MPa (20-130 psi); manual-drain variants open a lower 0.05 MPa floor. Choose the 40 um element for general protection or the 5 um element fitted here (code W) where downstream valves and cylinders need finer air. Gauge options are the embedded square gauge or an external round gauge in MPa, psi or bar - this unit carries the round psi gauge. Threads come as PT (standard) with G or NPT to order, and the bracket is included here (code J omits it); code K adds the reverse (check) valve fitted on this unit. Because flow is published as curves rather than a single rated figure, send us your application and we will confirm sizing from 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 flow for the GFR series as curves, not as a single rated figure, so there is no honest one-number answer to quote. Tell us your application and required conditions and we will confirm the sizing from the datasheet on request before you order.
This unit carries code A, the automatic drain, which discharges collected condensate without anyone bleeding the bowl by hand - useful on lines that run unattended. The family also offers manual drain and the differential-pressure default. Note the regulation floor differs by drain type: 0.15-0.9 MPa (20-130 psi) with automatic or differential-pressure drains, and 0.05-0.9 MPa (7-130 psi) with manual drain.
