The AirTAC GFR20008MLJF2W AirTAC Filter Regulator 1/4 in, 5 um 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 GFR20008MLJF2W is a size-200 filter regulator: water and particulate filtration plus pressure regulation combined in one body. This configuration takes a PT1/4 (1/4 in) port, carries a 5 um filter element (the finer of the two published grades), drains by hand through its manual drain, and is the low-pressure regulator type. It ships as coded with the embedded square gauge fitted, scaled in psi, and without a mounting bracket. The polycarbonate bowl lets you see collected condensate at a glance.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drain, 40 um or 5 um elements, gauge scale options, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so ask us and we will confirm the datasheet figures 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. |
|---|---|
| 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. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| (blank) | PT 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.

Bench-top test rigs and lab pneumatic circuits that run below standard line pressure get filtered, moisture-reduced air with fine 5 um particulate control, and the psi gauge lets technicians read the set point directly.
Spray guns and atomising heads are sensitive to both water and fine particles. This unit filters to 5 um ahead of the gun while the low-pressure regulator type holds the reduced pressure the finish demands.
Carton sealers, labellers and small wrapper stations on a packaging line take point-of-use air from this 1/4 in filter regulator, with the manual drain serviced during routine changeover.
Size and port set the ceiling on what this unit can handle: the 200 body with its 1/4 in PT port suits lighter-duty circuits, and stepping up to 300, 400 or 600 buys larger ports and more flow. Because flow is published as curves and not a single rated figure, ask us to check the curve against your air demand before ordering. On this code you have already chosen the 5 um element over the standard 40 um - the right call where finer particulate matters. The manual drain means an operator opens the bowl drain periodically; if nobody will do that reliably, consider the automatic or differential-pressure drain variants instead. The fitted square gauge reads in psi; MPa and bar scales exist if you prefer. PT is the standard thread here, with G (BSPP) and NPT available as order options, and a mounting bracket can be added on variants that carry one.
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 flow for the GFR series as performance curves, not as a single rated number, so there is no honest one-line figure to quote. Tell us your application and air demand and we will confirm the curve and sizing from the datasheet on request before you order.
The W at the end of the code selects the 5 um element instead of the standard 40 um, for finer particulate removal. The M selects the manual drain, so condensate is emptied by hand - the automatic and differential-pressure drain options are available on other variants if you would rather not rely on manual draining.
