The AirTAC GFR30010AJC2WG AirTAC Filter Regulator G3/8, 5 um 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 GFR30010AJC2WG is an AirTAC GFR300 filter regulator: water and particulate filtration plus pressure regulation combined in a single body. It filters compressed air down to 5 um (the fine W grade) and regulates downstream pressure across 0.15-0.9 MPa (20-130 psi). This configuration carries a G3/8 (BSPP) port, an automatic drain that expels collected condensate without manual attention, an external round gauge reading in psi, and no mounting bracket. The polycarbonate bowl is standard at this size; maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR300 series is the 300 size of the GFR filter-regulator family, which spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, PT, G or NPT threads, 40 um standard or 5 um optional filtration, differential-pressure, automatic or manual drains, and embedded square or external round gauges in MPa, psi or bar scales. Flow is published as curves rather than a single rated figure, so ask us to confirm the 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.

|---|---|
| 10 | Port size PT3/8". This body offers 08 = PT1/4", 10 = PT3/8", 15 = PT1/2". |
| A | Drain: Automatic drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |
| (blank) | Standard type. Blank is standard, L is the low-pressure type. |
| J | Supplied without bracket. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| G | G (BSPP) thread. PT is the default; G is BSPP and T is NPT. |
| (blank) | No reverse-flow valve (the default). |
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.

Filtered, regulated air feeding pneumatic clamps and tool-change cylinders on a machining centre, where the 5 um grade protects fine control valves from particulate carryover.
Supplying steady regulated pressure to actuated diverters and seal jaws on a filling or cartoning line, with the automatic drain handling condensate on a line that runs unattended.
Conditioning the air supply to sample-handling actuators and analytical instrument panels, where fine 5 um filtration and a local psi gauge keep instrument air clean and set correctly.
Size the unit against the air consumption of the downstream circuit: the GFR300 with its G3/8 port sits in the middle of the 200/300/400/600 range, and stepping up a size gives more flow capacity at the same pressure setting. The 5 um W grade suits circuits needing finer particulate removal than the 40 um standard element, such as instrument air or precision valves. The automatic drain keeps the bowl clear without intervention, which suits unmanned or hard-to-reach installations; manual and differential-pressure drains are available on other codes in the series. The round psi gauge on this code is the optional external type; embedded square gauges in MPa, psi or bar scales are the alternatives. Thread here is G (BSPP); PT is the standard thread and NPT is an order option, so match the thread to your pipework. Flow is published as curves, not a single rating - ask us to confirm sizing against your application before ordering.
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 we do not quote one number. Send us your application's air consumption and working pressure and we will confirm the flow from the datasheet before you order.
The A in the code GFR30010AJC2WG specifies an automatic drain, which expels collected condensate from the bowl without manual attention. If you prefer to drain by hand or by differential pressure, the M (manual) and blank (differential-pressure) versions are available as separate codes in the GFR300 series.
