The AirTAC GFR30010AJC2WGK 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 GFR30010AJC2WGK is an AirTAC GFR300 filter regulator, a single-body unit that removes water and particulate from compressed air and regulates downstream pressure in one pass. This configuration is a 300-size unit with a G3/8 (BSPP) port, a fine 5 um filter element, an automatic drain that ejects collected condensate without manual attention, a fitted reverse/check valve that holds downstream pressure when the supply is lost, and an external round gauge reading in psi. The standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi), with a maximum inlet pressure of 1.0 MPa (145 psi) and an operating temperature of -5 to 70 C (non-freezing). The polycarbonate bowl suits the 300 size, and the unit is ordered without a mounting bracket.
This is a genuine AirTAC part. The GFR family is available in 200, 300, 400 and 600 sizes with port sizes from 1/8 to 1 inch, and with choices of drain type, filter grade (40 um standard, 5 um optional), gauge style and scale, thread (PT standard; G and NPT as order options) and bracket. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm the datasheet and flow figures 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.

| 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. |
| K | Reverse-flow (reflux) valve fitted. |
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-change clamps and pneumatic actuators on a machining centre, where the 5 um element protects fine spool valves and the check valve holds clamp pressure through a supply dip.
Conditioning the air feeding diverters, pushers and sealing jaws on a packaging conveyor, with the automatic drain keeping condensate out of the line during continuous shifts without operator attention.
A point-of-use filter regulator on a drop line at an automotive assembly cell, giving each torque tool and clamping fixture its own 5 um filtered, psi-gauged supply isolated by the check valve.
Start with the size and port: the 300 size steps up from the 200 series for higher air demand, and the G3/8 port must match your piping or be adapted without narrowing the flow path. Choose the 5 um element (code W) over the 40 um standard when downstream valves, cylinders or instruments need finer filtration. The automatic drain on this unit suits unattended or hard-to-reach installations; manual and differential-pressure drains are the alternatives in the family. The fitted reverse/check valve holds set pressure through supply dips. Gauge choices are the embedded square gauge or the external round gauge fitted here, with MPa, psi or bar scales; this unit reads psi. Thread is G (BSPP) here, with PT standard and NPT available to order, and the bracket option is omitted on this code. Because flow is published as curves rather than 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. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR300 series as curves, not as a single rated figure, so we do not quote a number that could mislead your sizing. Tell us your application and required flow, and we will confirm the figures from the datasheet on request before you order.
Both are read straight from the code. The A position selects the automatic drain, which ejects collected condensate on its own instead of waiting for a manual twist of the bowl drain, and the W position selects the 5 um element instead of the 40 um standard grade. The 40 um grade with manual or differential-pressure drain is available in the same GFR300 family if your line does not need the finer filtration.
