The AirTAC GFR30010AF2WG AirTAC Filter Regulator G3/8, 5 um, Auto Drain is a genuine G-series filter regulator: water separation, 5 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has PT3/8" ports, a automatic 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 GFR30010AF2WG is a size-300 GFR filter regulator: filtration and pressure regulation combined in a single body. It removes water and particulate from compressed air through a 5 um element (the fine W grade, versus the 40 um standard), then regulates downstream pressure over 0.15-0.9 MPa (20-130 psi). This configuration has a G3/8 (BSPP) port, an automatic drain that expels collected condensate without manual attention, an embedded square gauge reading in psi, a mounting bracket, and a PC (polycarbonate) bowl. Maximum inlet pressure is 1.0 MPa (145 psi); operating temperature is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, drain choices (differential-pressure, automatic, manual), 40 um or 5 um filtration, square or square-external gauge options in MPa, psi or bar scales, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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 clean, regulated air to the tool-changer and clamping circuits of a CNC machining centre, where the 5 um element protects fine pilot valves from particulate and the regulator holds a steady setting for consistent clamp force.
Point-of-use conditioning on a cartoning or wrapping machine: the filter stage strips water carried over from the compressor, the regulator sets the pressure the sealing and pusher cylinders were designed for, and the automatic drain keeps the bowl clear through multi-shift running.
Conditioning the air feeding diverter gates and stopper cylinders on a distribution-centre conveyor line, where the automatic drain suits a unit mounted high on the frame and the psi gauge lets maintenance verify set pressure at a glance.
Size and port drive the choice: the 300 series with a 3/8 port suits lines whose air demand sits above what a 1/4-in unit comfortably passes, while 200 and 400 sizes step down or up from there. Because flow is published as curves and not a single rating, confirm your required flow against the GFR300 curve with us before ordering. For the element, choose 5 um (this unit, code W) when downstream equipment - valves, cylinders, gauges - needs finer protection than the 40 um standard; note the finer grade loads faster and the bowl should be checked accordingly. The automatic drain on this model suits unattended or hard-to-reach installations; choose manual drain where you prefer controlled, scheduled blowdown, or differential-pressure drain as the default. The embedded square gauge here reads psi; MPa and bar scales are available, and an external round gauge is an option. Thread is G (BSPP); PT is the standard thread and G or NPT are order options - specify to match your piping. A mounting bracket is included.
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 GFR flow as performance curves rather than a single rated figure, so we do not quote a l/min, m3/h or SCFM number. Tell us your operating pressure and required flow and we will confirm against the GFR300 datasheet curve whether this size is right, before you order.
The automatic drain (code A) discharges collected condensate by itself, which suits units mounted in awkward spots or on equipment that runs unattended; the alternatives are manual drain and the differential-pressure default. The 5 um element (code W) is the finer filtration option versus the 40 um standard, giving better protection for downstream valves and cylinders at the cost of a faster-loading element.
