The AirTAC GFR30010AJF2WGK 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 GFR30010AJF2WGK is an AirTAC GFR300 filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This configuration is threaded G3/8 (BSPP), carries the 5 um filter element (code W), drains condensate automatically (code A) and is fitted with the embedded square gauge scaled in psi. A reverse/check valve (code K) is built in, and no mounting bracket is supplied (code J). Maximum inlet pressure is 1.0 MPa (145 psi), the operating temperature range is -5 to 70 C (non-freezing), and the regulator adjusts from 0.15 to 0.9 MPa (20-130 psi). The polycarbonate bowl allows a clear view of the condensate level.
This is a genuine AirTAC part. GFR filter regulators are available in sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, with a choice of drain type, 40 um or 5 um filtration, gauge scale, PT/G/NPT thread and bracket options. Flow figures are published as curves rather than a single rating, so ask us to confirm the datasheet and sizing for your application before ordering.

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.
| GFR300 | G-series filter regulator, 300 body — sets the port range. |
|---|---|
| 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). |
| F | Gauge shape: Square. 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.

Feeds clean, regulated air to the tool-clamp and pallet-actuator circuits on a CNC machining centre; the 5 um element and automatic drain keep water and fine contamination out of the machine's valves.
Regulates the supply to diverters, stoppers and pusher cylinders on a packaging conveyor line, with the built-in check valve holding downstream pressure when the main supply dips.
Supplies regulated air to pick-and-place grippers and small actuators on a laboratory automation skid, where the square psi gauge gives operators a local setpoint readout.
Size the unit by the port step: this GFR300 is the 300 frame with a 3/8 inch port; step up to GFR400 or GFR600 when your line needs more flow capacity, or down to GFR200 for compact drops. Drain type is a real choice: differential-pressure (default), automatic (this model, code A) or manual (code M) - note the regulation range differs by drain: 0.15-0.9 MPa (20-130 psi) with automatic or differential-pressure drain, 0.05-0.9 MPa (7-130 psi) with manual. Filtration is 40 um standard or 5 um with code W, as fitted here. The embedded square gauge is standard with MPa/psi/bar scales (this unit: square, psi); an external round gauge is optional. Thread: PT is the standard, with G and NPT as order options (this model is G). Bracket: included by default, omitted with code J. Flow is published as curves, not a single rating, so 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 this series as curves, not as a single rated figure, so we do not quote a number on the page. Tell us your line pressure, downstream demand and port size, and we will confirm the flow figures from the datasheet for your application before you order.
Code A in the model number specifies the automatic drain, which expels collected condensate without operator attention. The GFR300 is also available with the differential-pressure drain (default) or a manual drain (code M). Note that the regulation range depends on the drain: 0.15-0.9 MPa (20-130 psi) with automatic or differential-pressure drain, and 0.05-0.9 MPa (7-130 psi) with manual drain.
