The AirTAC GFR20008LJF2WGK AirTAC Filter Regulator G1/4, 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 PT1/4" 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 GFR20008LJF2WGK is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This 200-size unit is specified with a G1/4 (BSPP) port, a 5 um filter element (the finer W grade, versus the 40 um standard), a differential-pressure drain, and a low-pressure regulator type. It comes fitted with an embedded square gauge scaled in psi and a reverse/check valve, and is supplied without a mounting bracket.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with port options from 1/8 to 1 inch and PT, G or NPT threads. The polycarbonate bowl on this size carries a maximum inlet pressure of 1.0 MPa (145 psi), and the unit operates from -5 to 70 C in non-freezing conditions. Flow is published as curves rather than a single rating, 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. 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.

| 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. |

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 clamp cylinders on a CNC fixture line, where the 5 um element protects the clamping valves from water and fine debris while the regulator holds the clamp pressure steady during the cut.
Mounted at the air inlet of a carton-sealing or wrapping machine, providing cleaned, regulated air to the fold-and-seal cylinders, with the psi gauge letting operators verify set pressure at a glance.
Prepares air for bench-top test rigs and small laboratory actuators, where the finer 5 um grade and the reverse/check valve help keep downstream devices stable when supply pressure fluctuates.
Start with the port: this unit is G1/4, so match it to your line size or step up or down a GFR size (200/300/400/600) if your flow path differs. The 5 um element here suits air that feeds sensitive components; choose the 40 um standard grade where only coarse water and particle removal is needed. The low-pressure regulator type is intended for lower set-pressure work - the exact range is not published, so confirm it with us. Drain is differential-pressure (standard); automatic or manual drains are available in the series. The square gauge is scaled in psi; MPa or bar scales and an external round gauge are options. G thread is as coded here; PT (standard) and NPT variants exist, and a bracket can be added if you did not order the J (no-bracket) version.
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 GFR series as curves, not as a single rated figure, so we do not quote a number here. Tell us your application and line conditions and we will confirm the relevant flow figures from the datasheet on request before you order.
The W in the code specifies the finer 5 um filter element instead of the 40 um standard, and the K specifies a reverse/check valve. The 5 um grade suits air feeding sensitive components, and the check valve holds the downstream setting if upstream supply drops. Both are catalogue options; the 40 um grade and no-valve versions are also available in the series.
