The AirTAC GFR20006LJC3WTK AirTAC Filter Regulator NPT1/8 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 PT1/8" 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 AirTAC GFR20006LJC3WTK is a low-pressure filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady in one compact body. This 200-size unit is fitted with a 1/8 in NPT port, the fine 5 um filter element (code W), a differential-pressure drain that bleeds collected condensate automatically as flow passes through, a round external gauge reading in bar, and a built-in reverse/check valve that holds the downstream setting if upstream supply is interrupted. It ships without a mounting bracket.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in and PT, G or NPT threads. The low-pressure regulator type is intended for applications that work below the standard adjust range; the exact range for this configuration is not published, so we confirm the datasheet and flow curves 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.
| 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. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. 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. |
| 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.

Fine 5 um air feeding small gripper cylinders and low-pressure actuation circuits, with the check valve holding the set pressure if the main supply dips mid-cycle.
Clean, moisture-reduced air at a gentle, stable pressure for pneumatic sample handling, purge air and delicate actuation inside benchtop analysers and test rigs.
The 5 um element catches water and particles that would ruin a finish, while the regulator lets the operator set the gun supply pressure and read it on the bar gauge.
Start with the port step: this unit is 200 size with a 1/8 in NPT port, so match it to the line size and the air your machine actually consumes - flow is published as curves rather than a single rating, so ask us to confirm sizing against the application before ordering. The 5 um element (code W) suits instruments, paint and sensing circuits; the standard 40 um element is the coarser general-purpose choice. The differential-pressure drain here is maintenance-light but relies on flow to purge; an automatic drain (A) or manual drain (M) can be ordered instead. The round gauge is scaled in bar; MPa and psi scales and an embedded square gauge are the other catalogue options. NPT is the thread on this unit; PT and G (BSPP) are the alternatives. A mounting bracket (J = none) can be added if you need panel fixing.
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, not as a single rated figure, so we do not quote a number here. Tell us your line pressure and the air consumption of your equipment and we will confirm the right size from the datasheet curves before you order.
The L code marks the low-pressure regulator type, intended for circuits that run below the standard adjust range; the exact range for this configuration is not published, so we confirm it on request. The K code means a reverse/check valve is fitted, which holds the downstream setting if the upstream supply is interrupted. Other decodable choices on this unit: 5 um filter element, differential-pressure drain, round bar gauge, no bracket, NPT1/8 port.
