The AirTAC GFR20008MLJF2WT AirTAC Filter Regulator, NPT1/4, 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, so one compact unit cleans the air and sets a stable downstream pressure. This configuration, GFR20008MLJF2WT, is the size 200 unit with a 1/4 in NPT port, a manual drain bowl in polycarbonate, a 5 um filter element (the finer of the two published grades), the low-pressure regulator type, an embedded square gauge scaled in psi, and no mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, a choice of drain types, 40 um standard or 5 um (W) filtration, gauge scales in MPa, psi or bar, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so ask us to confirm the figures for your application and we will check them against the datasheet 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. |
| 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.

Feeds cleaned, regulated air to the pneumatic clamps and grippers on a packaging line, with the 5 um element and manual-drain bowl keeping water and debris out of the downstream valves.
Supplies low-pressure regulated air to small pneumatic actuators on laboratory automation equipment, where the low-pressure regulator type and psi-scaled square gauge suit sensitive, instrument-grade circuits.
Provides filtered, regulated air to the stopper gates and diverter cylinders along a conveyor line, with the 1/4 in port matching the compact control valves typically fitted at each station.
Size and port: the four published sizes (200/300/400/600) step up in both port size and flow capacity, so match the size to the air demand of the circuit rather than to the pipe alone; this unit is size 200 with a 1/4 in NPT port. Drain: manual drain means someone opens the bowl drain periodically, which suits installations that are checked routinely; automatic and differential-pressure drains are the alternatives where unattended water removal matters. Filtration: 40 um is the standard element and 5 um (code W, fitted here) is the finer option for protecting sensitive downstream components. Gauge: the embedded square gauge is standard and this unit is scaled in psi; MPa and bar scales and an external round gauge are options. Thread: PT is the standard, with G (BSPP) and NPT as order options - this unit is ordered in NPT. Bracket: included by default, omitted on this code (J).
One honest note on sizing: flow for this family is published as curves, not as a single rated figure, so send us your flow and pressure requirements and we will confirm the correct size 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 GFR series as curves rather than a single rated figure, so we do not quote a l/min or SCFM number. Send us your required flow and working pressure and we will confirm the sizing for this unit against the datasheet on request.
The M in the code specifies a manual drain: condensate collected in the polycarbonate bowl is released by opening the drain by hand during routine checks. If the unit will be installed where it cannot be attended regularly, the same series is available with an automatic drain (code A) or the default differential-pressure drain instead.
