The AirTAC GFR30010LJF2W AirTAC Filter Regulator 3/8 in PT, 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 GFR30010LJF2W is an AirTAC GFR300 filter regulator: filtration and pressure regulation combined in a single body. It removes water and particulate from compressed air through a 5 um element and regulates downstream pressure as a low-pressure type. This configuration has PT3/8 (3/8 in) ports with PT thread as standard, a differential-pressure drain that bleeds condensate automatically as flow passes through, an embedded square gauge scaled in psi, and no mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing). The bowl on this 300 size is polycarbonate (PC).
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with a choice of ports, thread options (PT standard, G and NPT to order), drain types, filter grades and gauge scales. Because flow is published as curves rather than a single rating, we confirm flow and other datasheet 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. 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.

| (blank) | Drain: Differential-pressure drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| J | Supplied without bracket. |

| 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. |
| (blank) | PT 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.

On a machining fixture that clamps with air at reduced pressure, this unit filters the supply to 5 um and holds the regulated low-pressure setting, with the psi gauge giving the operator a direct reading at the fixture.
On a packaging conveyor fitted with air-jet nozzles that sweep debris off containers, the unit conditions the supply in one body: water and fine particulate removed at 5 um and nozzle pressure regulated to the level the jetting needs.
For benchtop lab equipment fed from a shop-air header, the 5 um element protects sensitive internal valves from condensate and particles while the low-pressure regulator and psi gauge hold a gentle, visible supply pressure.
Choose the size and port step against the air demand of the circuit: this unit is size 300 with PT3/8 (3/8 in) ports; larger sizes carry larger ports and more flow. The 5 um element (code W) suits points where finer filtration is wanted; the 40 um standard element remains available in the family. Drain options are differential-pressure (fitted here, which discharges condensate on a pressure differential), automatic, or manual. The embedded square gauge is fitted here with a psi scale; MPa or bar scales and an external round gauge are alternatives. PT thread is standard on this model, with G (BSPP) and NPT available as order options; a mounting bracket can be added where the family offers it.
One honest note before ordering: flow is published as curves, not a single rated figure, and the exact regulation range of the low-pressure type is not published in the material we hold. Ask us to confirm sizing and the regulation range against your application 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 rather than a single rated figure, so we do not quote a number here. Contact us with your application and we will confirm the flow from the datasheet so you can size the unit correctly.
The W in the code GFR30010LJF2W selects the 5 um filter element instead of the 40 um standard, and F2 selects the embedded square gauge with a psi scale. Both are standard decodable options on the GFR family; the 40 um element and MPa or bar gauge scales can be ordered in other configurations.
