The AirTAC GFR300C10AC2WG AirTAC Filter Regulator G3/8 5 um Auto Drain 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 GFR300C10AC2WG is a GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration carries a G3/8 (BSPP) port, a 5 um filtration element, an automatic drain and a round gauge scaled in psi, with a metal bowl and a mounting bracket included. The standard regulator type covers an adjustment range of 0.15-0.9 MPa (20-130 psi), and maximum inlet pressure is 1.0 MPa (145 psi).
This is a genuine AirTAC part from the GFR300 size class, one of four GFR sizes (200/300/400/600) spanning 1/8 to 1 inch ports. Across the series you can order manual, automatic or differential-pressure drains, 40 um or 5 um elements, MPa, psi or bar gauge scales, and PT, G or NPT threads. Working temperature is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so ask us to confirm 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 a machine tool's pneumatic valves, clamps and tool-change actuators: the 5 um element strips water and fine particulate before they reach the control valves, the regulator holds a steady setpoint, and the automatic drain clears condensate without a daily walk-round.
Supplying the cylinders that push, divert and stop cartons on a packaging conveyor: filtered and regulated air keeps stroke behaviour consistent through the shift, and the round psi gauge lets a line technician verify the setting at a glance.
Mounted at the air drop feeding a robotic weld cell's grippers and clamps: the unit conditions the supply locally so cell-side components see clean, regulated air, while the automatic drain handles moisture collected in the drop leg.
Start with the port step: the GFR300 in 3/8 inch sits in the middle of the GFR range, so step up to GFR400 or GFR600 or down to GFR200 depending on the flow your line needs - we will confirm sizing against the published flow curves before you order. This unit already carries the 5 um (W) element rather than the 40 um standard, an automatic drain rather than manual or differential-pressure, and a round psi gauge; other gauge scales (MPa, bar) and drain types are orderable in the same size. The G thread is the BSPP option - PT is the standard thread and NPT is also available to order. A mounting bracket is included with this code.
Because AirTAC publishes flow only as curves and not as a single rated figure, send us your application details and we will confirm the right size and settings from the datasheet before you commit.
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 GFR300 as curves rather than a single rated figure, so there is no honest one-number answer we can quote. Send us your application - required flow, working pressure and downstream equipment - and we will confirm the sizing against the datasheet curves before you order.
The automatic drain expels collected condensate from the bowl on its own, so the unit suits panels and cells that are not checked daily. The same GFR300 size is also available with a manual drain (you drain it by hand) or a differential-pressure drain; note that the regulator adjustment range differs by drain type - 0.15-0.9 MPa (20-130 psi) for automatic and differential-pressure drains, 0.05-0.9 MPa (7-130 psi) for manual.
