The AirTAC GFR30010LC2WG 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 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 GFR30010LC2WG is a GFR300 filter regulator: one body that removes water and particulate from compressed air and reduces pressure downstream. This configuration carries a G3/8 (3/8 inch) G-thread port, the fine 5 um filter element (code W, versus the 40 um standard), a differential-pressure drain, and the low-pressure type regulator for circuits whose working pressure sits below what the standard type covers - the exact adjustment range is not published, so confirm it with us. A round external gauge scaled in psi is fitted, the mounting bracket is included, and no reverse/check valve is fitted. The polycarbonate bowl suits this 300 size (only size 600 uses an aluminium alloy bowl). 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 GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, drain choices (differential-pressure, automatic or manual), 40 um or 5 um filtration, embedded square or external round gauges in MPa, psi or bar scales, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so ask us to confirm sizing or any datasheet figure for your application before you order.

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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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.

| C | Gauge shape: Round. C is round, F is square. |

| 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. |

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 reduced-pressure air to clamping cylinders on an assembly-line fixture, where the 5 um element helps protect cylinder seals and the psi gauge lets operators read the set point directly.
Supplying filtered, reduced-pressure air to analytical instruments and test benches that call for fine 5 um air and a stable low supply pressure rather than full line pressure.
Regulating supply to pick-and-place and conveying actuators on a packaging line, with the differential-pressure drain keeping condensate off the element without manual attention.
Size and port step up together with air demand: this 300 unit carries a G3/8 port, and if your consumption sits near the top of what a size serves, move up a size rather than oversizing the regulator. Filtration here is the 5 um W grade - choose it when downstream valves, cylinders or instruments need finer air than the 40 um standard; otherwise the standard element is the more economical choice. The drain is differential-pressure (bleeds automatically as the element loads up); automatic and manual drains are orderable alternatives. The fitted round gauge reads in psi; an embedded square gauge with MPa, psi or bar scale is the alternative. Thread is G (BSPP); PT is the standard offering and NPT is orderable - these are specifications, not delivery promises. Because flow is published as curves, not a single rating, send us your application conditions 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 this series as curves, not a single rated figure, so we do not quote a number here. Send us your operating pressure and air demand and we will confirm sizing against the datasheet on request.
L marks the low-pressure type regulator; its exact adjustment range is not published, so confirm it with us if your set point is critical. The rest of the code decodes as: 300 size with G3/8 port, G thread, differential-pressure drain, 5 um element (W), round psi gauge (C2), no reverse valve, bracket included.
