The AirTAC GFR20008MLJF3WT AirTAC 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 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 AirTAC GFR20008MLJF3WT is a GFR-series filter regulator: it removes water and particulate from compressed air and holds downstream pressure in one compact body. This 200-size configuration is built with a 1/4 in NPT port, a 5 um filter element for finer air than the standard grade, a manual drain on the PC (polycarbonate) bowl, a low-pressure regulator, an embedded square gauge scaled in bar, and no mounting bracket.
It is a genuine AirTAC part from the GFR filter-regulator line, made in sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 in and a choice of drain type, filter grade, gauge and thread. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. AirTAC publishes flow for this series as curves rather than a single rating, so ask us and we will confirm the datasheet figures for your application.

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. |
|---|---|
| 08 | Port size PT1/4". 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. |
| (blank) | No reverse-flow valve (the default). |
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.

Filtered, regulated air to the clamps and fixtures on a CNC machining cell, with the 5 um element helping keep water and particulate out of the clamp cylinders and the bar-scale gauge giving a local pressure readout.
Supplying spray guns on a paint line with cleaned air and a steady, lower set pressure from the low-pressure regulator, with the bowl drained by hand at the end of each shift.
Feeding bench-top test rigs and pneumatic lab instruments that run on clean, low-pressure air, where the 5 um grade and a stable set point matter more than high flow.
Match the size and port to the flow your line needs: 200 is the compact step of the GFR range and this unit carries a 1/4 in NPT port, with larger sizes moving up in port and flow. This is the low-pressure regulator type, so if your circuit sets pressure well below standard ranges, confirm the exact regulation range with us before ordering - it is not published as a single figure. The 5 um element suits applications needing finer air than the standard 40 um grade. The manual drain means collected water is bled from the bowl by hand; automatic and differential-pressure drain versions exist if you prefer not to. The square gauge reads in bar, with MPa, psi scales and an external round gauge available as options. Thread here is NPT; PT is the standard and G (BSPP) can be ordered. Flow is published as curves, not a single rated figure - send us your flow and pressure targets and we will confirm sizing against the datasheet before you order.
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 GFR flow as curves rather than a single rated figure, so we do not quote a l/min or SCFM number for this unit. Send us your flow and pressure targets and we will confirm the datasheet curve for the GFR200 at the 1/4 in port before you order.
It means you open the drain valve by hand to bleed collected water from the PC bowl. If you would rather not do that, automatic and differential-pressure drain versions are available in the same series - tell us and we will identify the equivalent code for your port and options.
