The AirTAC GFR30010MC2WG AirTAC Filter Regulator 3/8 in, 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 manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The GFR30010MC2WG is an AirTAC GFR300 filter regulator: it removes water and particulate from compressed air and holds downstream pressure in one body. This configuration has a G3/8 (3/8 in) port with G (BSPP) thread, a 5 um filter element (W grade), a manual drain on the polycarbonate bowl, a round pressure gauge reading in psi, and the standard regulator with an adjustment range of 0.05-0.9 MPa (7-130 psi). No reverse/check valve is fitted, and a mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi); working temperature is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR range covers sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and options for thread (PT is the standard offering; G and NPT are order options), drain type (differential-pressure, automatic or manual), filter grade (40 um standard, 5 um optional) and gauge scale (MPa, psi or bar). 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 0.05 - 0.9 MPa (7 - 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". |
| M | Drain: Manual drain — this also sets the regulating band (0.05 - 0.9 MPa (7 - 130 psi)). |
| (blank) | Standard type. Blank is standard, L is the low-pressure type. |
| (blank) | Mounting bracket included. |
| (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 the directional control valves on a carton-sealing machine, with the 5 um element helping keep valve pilot passages clean and the psi gauge showing set pressure at a glance.
A filter regulator at the drop feeding air-assisted spray guns in a finishing booth: water and grit removed ahead of the gun while the regulator holds a steady atomising pressure for consistent finish quality.
Regulated supply to grippers and small cylinders on an assembly-cell robot, where stable pressure keeps part handling repeatable and the manual drain suits a shift-end maintenance routine.
Size and port set the flow path: this unit is size 300 with a G3/8 port, one step up from 1/4 in - match the port to your line size and required flow. Drain choice matters: a manual drain needs someone to open it during servicing, while automatic and differential-pressure drains discharge condensate without attention. The filter grade here is 5 um (W code) against the 40 um standard - the finer element suits downstream valves and instruments that tolerate less particulate. The round gauge reads psi; MPa and bar scales are available, and an embedded square gauge is the standard alternative. Thread is G (BSPP); PT is the standard offering and NPT is an order option. A mounting bracket is included. Flow for this family is published as curves, not a single rated number, so send us your flow requirement 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 GFR series as curves rather than a single rated figure, so we do not quote a number here. Send us your line size and flow requirement and we will confirm the datasheet curve for this 3/8 in unit before you order.
This unit's bowl has a manual drain: condensate is released by opening the drain during servicing. If you prefer unattended condensate removal, the same GFR300 size is available with automatic or differential-pressure drains - tell us and we will quote the alternative code.
