The AirTAC GFR20006MLJF3WTK 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 manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The GFR20006MLJF3WTK is an AirTAC GFR200 filter regulator: one body that removes water and particulate from compressed air and regulates downstream pressure. This configuration is the 200 size with a 1/8 in NPT port, a 5 um filter element (code W) for finer filtration than the standard 40 um grade, a manual drain you operate by hand to empty the PC bowl, and the low-pressure regulator type for circuits set below standard ranges. It also carries a built-in reverse (check) valve, which holds downstream pressure if the upstream supply drops, and an embedded square gauge reading in bar.
This is a genuine AirTAC part from the G-series range, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in and thread options in PT, G (BSPP) and NPT. Flow is published in the catalogue as curves rather than a single rated figure, so ask us to confirm the flow or datasheet figures against 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". |
| M | Drain: Manual drain — this also sets the regulating band (0.05 - 0.9 MPa (7 - 130 psi)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| J | Supplied without bracket. |
| (blank) | Pressure gauge fitted (blank). |
| 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. |
| 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.

On a small assembly cell with grippers and vacuum ejectors, this unit filters the supply to 5 um, regulates it at low pressure for delicate handling, and the check valve holds the downstream circuit if the plant air dips.
Bench rigs running instruments and pneumatic test fixtures get clean, finely filtered air and a low, stable set pressure read locally on the square bar gauge, with manual draining between sessions.
Feeding positioners and valve-actuator pilot circuits on a process skid, the unit strips water and particles ahead of sensitive components and regulates the pilot pressure, with the check valve guarding against supply loss.
Start with the port step: this unit is the 200 size with a 1/8 in NPT port, so match it to the line size and the air demand of the circuit - larger sizes (300/400/600) carry larger ports and more flow. Because flow is published as curves rather than a single rating, ask us to confirm sizing against your application before ordering. The 5 um element (W) suits circuits that need finer filtration than the standard 40 um grade; the manual drain suits positions where an operator can bleed the bowl on a routine, and automatic or differential-pressure drains are available on other variants. The square gauge reads in bar; MPa and psi scales and an external round gauge are options. NPT is the thread on this code - PT and G (BSPP) are orderable alternatives - and this J-coded unit comes without a mounting bracket, so plan your fixing accordingly.
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 this series as curves, not as a single rated figure, so we do not quote a number. Tell us your line size and air demand and we will confirm the flow from the datasheet against your application before you order.
The M in the code selects the manual drain: the PC bowl is emptied by hand, which suits positions an operator visits routinely; automatic and differential-pressure drains are available on other variants. The K in the code fits a reverse (check) valve, which holds downstream pressure if the upstream supply is lost.
