The AirTAC GFR20008LJF2WT AirTAC Filter Regulator 1/4 NPT Low-Pressure 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 GFR20008LJF2WT is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one compact body. This 200-size unit is fitted with a 1/4 in NPT port, the fine 5 um filter element (code W), a differential-pressure drain that bleeds collected condensate automatically as flow passes through, and the low-pressure (L) regulator type for applications that run at reduced settings. The embedded square gauge reads in psi, and the polycarbonate bowl lets you see the condensate level at a glance. No mounting bracket is included with this configuration.
This is a genuine AirTAC part from the GFR series, which spans sizes 200 to 600 with port sizes from 1/8 to 1 in and options including manual or automatic drains, a 40 um standard element, alternative gauge scales, G (BSPP) or NPT threads, and a reverse/check valve. Flow is published as curves rather than a single rating, so contact us and we will confirm the 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. |
| T | NPT 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 and regulates the air to clamp cylinders on a machining or assembly fixture, with 5 um filtration protecting the valve stack and the low-pressure type holding reduced clamp settings.
Supplies cleaned, regulated air to the tape-head and box-hold cylinders of a carton sealer, where the differential-pressure drain keeps condensate moving out during continuous production runs.
Conditions the supply to a bench-top pneumatic test rig, where the fine 5 um element and the psi-reading square gauge give clean air and a clear local pressure reference for repeatable tests.
Start with the port size: this unit is 1/4 in NPT in the 200 frame; step up to 300, 400 or 600 if your line needs larger ports and more flow capacity. Choose the drain to suit access: differential-pressure (as fitted here) suits continuously flowing lines, automatic (code A) suits intermittent flow or unattended positions, and manual (code M) suits supervised points. Pick the element grade: 40 um standard for general protection, 5 um (W, as here) for finer downstream equipment. The square gauge is fitted in a psi scale; MPa and bar scales are available. PT is the standard thread, with G (BSPP) and NPT as catalogue options - order the suffix that matches your piping. A mounting bracket (code J omits it) is optional on this family.
Because flow is published as curves rather than a single rated figure, 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, not as a single rated number, so we do not quote a figure here. Tell us your line pressure and the air demand of your equipment, and we will confirm the datasheet flow curve and sizing for this 1/4 in NPT unit on request.
W is the filter grade: this unit carries the fine 5 um element instead of the 40 um standard. L is the low-pressure regulator type, intended for applications that run at reduced settings; the exact regulation range for the low-pressure type is not published, and we will confirm it from the datasheet on request. The trailing T is the NPT thread option (PT is the standard), and J means no mounting bracket is fitted.
