The AirTAC GFR20008MLJF2WG AirTAC Filter Regulator G1/4, 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 GFR200 series combines water and particulate filtration with pressure regulation in a single body. This configuration carries a G1/4 (BSPP) port, a 5 um filter element, a manual drain and the low-pressure type regulator, with a square pressure gauge fitted that reads in psi. The polycarbonate bowl lets you see collected condensate at a glance, and you open the manual drain to expel it. No mounting bracket is included and no reverse-flow check valve is fitted on this code.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, plus drain, filter-grade, gauge, thread and bracket options, so a matching unit exists for most lines. AirTAC publishes flow 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. |
| G | G (BSPP) 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.

Feeding spray guns on a finishing line: the 5 um element strips water and particulate before the atomising air reaches the gun, and the low-pressure regulator holds the gun supply at the lower set pressure the finish calls for.
Supplying clamp cylinders on a machining fixture: filtered, regulated air keeps clamp force repeatable part after part, and the fitted psi gauge gives the setter a direct readout at the fixture.
Running the seal and fold cylinders on a carton-sealing or wrapping machine: one body cleans the air and sets the working pressure, with the manual drain emptied during scheduled line checks.
The real choices on this family are the size and port (200 series here, 1/4 in), the drain (manual on this unit, versus automatic or differential-pressure options), the filter grade (5 um here versus the 40 um standard), the gauge and its scale (square, psi fitted here; MPa and bar scales exist), the thread (G/BSPP here; PT is the standard and NPT is an order option) and the bracket (not included on this code). Step up or down through the 200/300/400/600 sizes to match the flow your line needs. AirTAC publishes flow as curves, not a single rating, so send us your demand 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 flow for the GFR200 as curves, not a single rated figure, so we do not quote a number here. Send us your flow and pressure demand and we will confirm the datasheet figures for this exact model on request.
The M in the code selects the manual drain: you open it to release the condensate collected in the polycarbonate bowl. Automatic and differential-pressure drains are decodable options on the GFR family, so if you would rather not rely on periodic draining, ask us and we will quote the right code.
