The AirTAC GFR20008LJF2WG 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 GFR20008LJF2WG is an AirTAC GFR200 filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady in one body. This configuration has a G1/4 (BSPP) port, a 5 um filter element, a differential-pressure drain and the low-pressure (Type L) regulator, with an embedded square gauge scaled in psi and no mounting bracket. The polycarbonate bowl shows condensate at a glance, max inlet pressure is 1.0 MPa (145 psi), and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR series is available in sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, and with choices of drain type, 40 um or 5 um filtration, gauge scale and PT, G or NPT thread. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures 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. 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.

|---|---|
| 08 | Port size PT1/4". This body offers 06 = PT1/8", 08 = PT1/4". |
| (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. |
| (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. |
| (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, pressure-stabilised air for spray guns in a finishing booth: the 5 um element strips water and particulate before the mist, and the low-pressure regulator holds a steady setting at the gun.
A compact filter regulator for bench-top test rigs and laboratory pneumatic fixtures that run at reduced pressure, where the psi-scaled square gauge gives a direct local readout.
Conditioning the air feed to clamp and hold cylinders on a packaging conveyor, keeping contaminant-laden shop air out of the actuators while holding a fixed low-pressure setting.
Size the GFR by port and expected flow: this unit is the 200 size with a G1/4 port, while the larger 300, 400 and 600 sizes carry bigger ports and more flow. The 5 um element (code W) suits air that needs finer cleaning than the 40 um standard. The drain is differential-pressure, which bleeds the bowl as the pressure differential rises; automatic and manual drains are available on other codes. The square gauge is scaled in psi, with MPa or bar scales and an external round gauge available on other codes. The Type L code marks the low-pressure regulator version - its exact adjustment range is not published, so confirm it with us. Thread is G (BSPP); PT is the standard thread and NPT is an order option, and a mounting bracket can be specified on other codes. 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. 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. Tell us your application and we will confirm the relevant datasheet figures for this G1/4, 5 um unit on request.
The L code marks the low-pressure regulator version of the GFR200. Its exact adjustment range is not published in the catalogue data we hold, so contact us and we will confirm the range from the datasheet before you order.
