The AirTAC GFR20008MLJC2WGK 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 GFR20008MLJC2WGK is a filter regulator: water and particulate removal plus pressure regulation in a single body. This configuration is the size 200 unit with a G1/4 (1/4 in) port, a 5 um filter element (code W, versus the standard 40 um), a manual drain, and the low-pressure regulator type. It is fitted with an external round gauge reading in psi, and a reverse/check valve (code K) is built in; no mounting bracket is supplied with this code. 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 from the GFR series, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of 40 um or 5 um filtration, manual, automatic or differential-pressure drains, standard or low-pressure regulation, gauge scale options, and PT, G or NPT threads. Flow is published by AirTAC as curves rather than a single rated figure, so we confirm the datasheet and sizing 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.

|---|---|
| 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). |
| C | Gauge shape: Round. 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. |
| 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.

Feeding filtered, regulated air to gripper and cylinder circuits on an electronics assembly line. The 5 um element protects fine pneumatic components, and the low-pressure regulator suits circuits that must not see full line pressure.
Conditioning shop air for bench-mounted test rigs and pilot rigs. The psi round gauge gives direct readings in familiar units, and the manual drain lets technicians remove accumulated water as part of each setup routine.
Supplying directional control valve stacks on packaging lines from a single conditioning point. The reverse/check valve helps hold the downstream circuit, and the combined filter-regulator body saves panel space over separate units.
Start with the size and port: this is the smallest GFR size (200) with a 1/4 in port, so match it against the air consumption of the circuit it feeds - if your demand is higher, the 300, 400 or 600 sizes step up in port and capacity. This code carries the 5 um element; choose it when downstream components need finer filtration than the standard 40 um, and note the manual drain means the bowl is emptied by hand during routine checks rather than automatically. The low-pressure regulator type (code L) is the right choice where the circuit must be held well below full line pressure; the exact adjustment range for the low-pressure type is not published, so ask us to confirm it. The round gauge reads in psi; square embedded gauges and MPa or bar scales are the alternatives. Thread here is G (BSPP); PT is the standard and NPT is also an order option, and brackets can be added where this no-bracket code needs panel fixing. Because AirTAC publishes flow only as curves, not a single rating, ask us to confirm sizing against your application before ordering.
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 the GFR series as curves rather than a single rated figure, so there is no one rated flow number we can honestly quote. Tell us your application and air demand and we will confirm the flow and sizing figures from the datasheet on request.
The M in this model code means a manual drain: accumulated water is released from the bowl by hand as part of routine maintenance. The GFR family also offers automatic and differential-pressure drains, and the low-pressure regulator type in this code is likewise a selectable option - ask us to decode or quote the alternative configuration you need.
