The AirTAC GFR20008LJC1WTK AirTAC Filter Regulator NPT1/4 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 GFR20008LJC1WTK is a GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single compact body. This 200-size unit is specified with 1/4 in NPT ports, a fine 5 um filter element (code W), a differential-pressure drain that bleeds collected condensate automatically whenever the pressure differential is sufficient, the low-pressure regulator type for circuits that run at reduced set pressures, a round external pressure gauge scaled in MPa, and a built-in reverse/check valve that holds downstream pressure when the supply is lost. It carries no mounting bracket (code J). Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. The polycarbonate bowl keeps the bowl and drain visible for inspection.
This is a genuine AirTAC part from the GFR filter-regulator family, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in and thread options in PT (standard), G (BSPP) and NPT. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm the datasheet and flow-curve 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). |
| C | Gauge shape: Round. C is round, F is square. |
| 1 | Gauge scale: MPa. 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.

A bench or C-frame press with air-actuated clamps that must close at a reduced set pressure: the low-pressure regulator type sets the holding pressure while the 5 um element keeps fine spool and valve surfaces clean.
Feeding positioners and pilot-operated control valves on a process line, where the check valve holds the pilot circuit pressurised during supply dips and the differential-pressure drain keeps condensate out of the pilot stage.
Supplying gauges, transducers and test fixtures that need clean, finely filtered air at a stable reduced pressure, with the round MPa gauge giving a clear local reading of the set point.
Choose the size and port step against the air demand of the circuit: this unit is size 200 with 1/4 in NPT ports, and larger GFR sizes step up in port and flow capacity. This configuration fixes several real choices for you: the 5 um element (W) instead of the standard 40 um, the differential-pressure drain instead of automatic (A) or manual (M), the low-pressure regulator type instead of standard, the round MPa gauge instead of the embedded square gauge, NPT instead of PT or G, no bracket, and a fitted reverse/check valve. If you need a different combination, the same series can be ordered with those options. One honest note on sizing: flow for this series is published as curves, not a single rating, so send us your application details and we will confirm the figures from the datasheet before you order.
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 rather than a single rated figure, so we do not quote a rated flow number. Tell us your application and we will confirm the flow-curve and datasheet figures for this 200-size, 1/4 in NPT unit on request before you order.
The W code fits the fine 5 um element instead of the standard 40 um element, which suits downstream components sensitive to finer particles. The blank drain code is the differential-pressure type: condensate is discharged automatically when the pressure differential across the drain is sufficient, with no manual draining required in normal operation.
