The AirTAC GFR300C10AF2WG 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 GFR300C10AF2WG is a GFR300 filter regulator: a single body that removes water and particulate from compressed air and then regulates downstream pressure. This configuration carries a G3/8 port, a 5 um filter element (the finer W grade, versus the 40 um standard), an automatic drain that clears condensate from the bowl without manual attention, and a standard regulator with an adjustment range of 0.15-0.9 MPa (20-130 psi). An embedded square gauge reading in psi is fitted, a mounting bracket is included, and no reverse/check valve is fitted. Maximum inlet pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR300 series is one of four sizes (200, 300, 400 and 600) with port options from 1/8 to 1 inch, a choice of differential-pressure, automatic or manual drain, 40 um or 5 um filtration, gauge scales in MPa, psi or bar, and PT, G or NPT threads. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm sizing and datasheet details 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 workshop pneumatic press with filtered, regulated air: the 5 um element protects the valve train from particulate and the regulator holds a steady working pressure at the press cylinder.
On a bottling or cartoning line, the automatic drain clears condensate between shifts and the psi square gauge lets operators verify the set pressure for gate and divert cylinders without shutting the line down.
Supplying pick-and-place modules and test fixtures in a laboratory rig, where the 5 um grade and stable regulated pressure keep small pilot valves and actuators behaving repeatably run after run.
Choose the size by port and flow demand: this unit is size 300 with a G3/8 port, and the smaller 200 and larger 400/600 frames step port and flow capacity up or down. Drain type is a real decision: automatic (fitted here) suits unattended duty, manual suits periodic checks, and the differential-pressure default drains only when the pressure drop justifies it. Filter grade is 40 um standard or 5 um (code W, fitted here) for finer protection. Gauge scale is selectable in MPa, psi or bar, and an external round gauge is available as an option. Thread is PT as standard with G and NPT as order options, and a mounting bracket is included. Because flow is published as curves rather than a single rating, send us your flow and pressure requirements 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 flow for the GFR300 series as curves rather than a single rated figure, so we do not quote a number here. Tell us your required flow and working pressure and we will confirm sizing from the datasheet on request.
The W-coded 5 um element filters finer than the 40 um standard, which suits downstream valves and actuators that need cleaner air. The automatic drain ejects collected condensate on its own, so the bowl does not need manual draining on regularly running equipment.
