The AirTAC GFR20008LJF3WT AirTAC Low-Pressure Filter Regulator NPT1/4 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 GFR20008LJF3WT is a filter regulator: in one body it removes water and particulate from compressed air and reduces pressure to the working set point. This configuration is built on the GFR200 size with a 1/4 in NPT port, the finer 5 um filtration element, a differential-pressure drain that discharges condensate as the pressure differential across the element builds, and the low-pressure regulator type for applications fed at reduced set points. The embedded square gauge scaled in bar gives a direct reading at the unit, the polycarbonate bowl shows condensate level at a glance, and the bracket is omitted on this code. Maximum 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 from the G series, which spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in and thread options in PT (standard), G (BSPP) and NPT. Filter grade, drain type, gauge style and scale, bracket and reverse valve can all be specified per code. AirTAC publishes flow as curves rather than a single rated figure, so we confirm flow and full datasheet details 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. |
| 3 | Gauge scale: bar. 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.

At the drop feeding spray guns in a finishing booth, this unit filters the shop air to 5 um and holds a low, steady set point so the gun sees consistent pressure and the finish stays free of water spotting and grit.
On a lab test bench running instruments and small actuators at reduced pressure, the low-pressure regulator type sets gentle supply levels while the bar-scaled square gauge gives a direct local reading.
Mounted at the air drop to a cartoning or wrapping machine, it filters and regulates the supply in one body, and the differential-pressure drain keeps accumulated condensate out of the machine's valves and cylinders.
Pick the size and port against the air demand of the machine: GFR200 with a 1/4 in port suits compact supply points, while GFR300, 400 and 600 step up in port and flow capacity. This code carries the 5 um element (W), the finer of the two grades; the 40 um standard grade is the choice where coarse protection is enough. Drain is differential-pressure here, with automatic (A) and manual (M) variants also available. The square gauge is fitted and scaled in bar, with psi and MPa scales and an external round gauge as alternatives. Thread is NPT on this code, with PT (the standard) and G as catalogue options, and the mounting bracket is omitted (J). Because AirTAC publishes flow 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. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes G-series flow as curves, not as a single rated figure, so we do not quote a number here. Send us your inlet pressure, set pressure and air demand and we will confirm from the datasheet whether the GFR200 size at 1/4 in NPT is correctly sized for your application before you order.
The W in the code GFR20008LJF3WT selects the 5 um element, the finer of the two filter grades AirTAC offers on this family; 40 um is the standard grade where coarse protection is sufficient. Both grades share the same body, drain, gauge and port options, so you can move between them without changing the rest of the specification.
