The AirTAC GFR20006LJNWTK AirTAC Filter Regulator NPT1/8 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 PT1/8" 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 GFR20006LJNWTK is an AirTAC GFR200 low-pressure filter regulator: a single body that first removes water and particulate from compressed air, then regulates the downstream pressure. This configuration takes a 1/8 in NPT port and carries the W filter grade, a 5 um element, for finer filtration than the 40 um standard. Condensate is discharged by the differential-pressure drain, and a reverse/check valve is fitted to block backflow. No pressure gauge is supplied and no mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi); operating temperature is -5 to 70 C (non-freezing). As a low-pressure type, its exact regulation range is not published in our data - we confirm it on request.
This is a genuine AirTAC part from the GFR series, which spans sizes 200 to 600 with ports from 1/8 to 1 in, a choice of PT, G (BSPP) or NPT threads, drain types and filter grades, and polycarbonate bowls at this size. Flow for the series is published as curves rather than a single rating, so ask us to confirm sizing and 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.
| GFR200 | G-series filter regulator, 200 body — sets the port range. |
|---|---|
| 06 | Port size PT1/8". 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. |
| N | No pressure gauge (N). |
| (blank) | Gauge shape: Factory standard. C is round, F is square. |
| (blank) | Gauge scale: Factory standard. 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. |
| K | Reverse-flow (reflux) valve fitted. |
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.

Supplies filtered, regulated air to the clamping cylinders of a carton-sealing line, where the low-pressure regulator holds a gentle, repeatable clamp force and the 5 um element keeps contaminants out of the valve seats.
Conditions the atomizing air on a furniture finishing line: the 5 um element strips water and pipe scale before the spray gun, while regulation keeps the supply steady for a consistent finish.
Feeds the guide-rail and stopper cylinders on a bottling conveyor, where filtered and regulated air at reduced pressure drives the positioning moves and the check valve blocks backflow if the supply dips.
The real choices in this code are: size 200 with a 1/8 in NPT port (step up through sizes 300, 400 and 600 when your air demand outgrows the port); the 5 um W filter grade, where finer filtration than the 40 um standard is required; the differential-pressure drain, which discharges condensate automatically as flow drops, against the automatic or manual drain variants; and the NPT thread, with G (BSPP) and PT available to order. No gauge is fitted (code N) and no bracket is included (code J) on this variant. Because AirTAC publishes flow 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. 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 number. Send us your line pressure and air demand and we will confirm sizing against the datasheet on request.
No. The N in the code means no gauge is fitted on this configuration. Gauge options with MPa, psi or bar scales are available on other GFR variants - tell us which scale you need when ordering and we will point you to the right code.
