The AirTAC GFR20008MLF2WTK AirTAC Filter Regulator NPT1/4 Low-Pressure 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 GFR20008MLF2WTK is an AirTAC GFR200 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single compact body. This configuration is sized 200 with a 1/4 in NPT thread, carries the fine 5 um filter element (code W) for applications that need cleaner air than the standard 40 um grade, and uses a manual drain, so the bowl must be drained by hand as part of routine maintenance. It is the low-pressure regulator type, the drain bowl is polycarbonate (PC), a square pressure gauge with a psi scale is fitted, a reverse/check valve is installed, and a mounting bracket is included.
This is a genuine AirTAC part from the G-series air-treatment line, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in and PT, G and NPT thread options. Flow figures for this series are published as curves rather than a single rated number, so ask us to confirm the datasheet and sizing for your application before ordering.

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. |
| (blank) | Mounting bracket included. |
| (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. |
| 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 clean, regulated low-pressure air to the pneumatic clamps and tool-change actuators on a machining centre, where the 5 um element protects spool valves from fine swarf-laden condensate.
Supplying filtered, pressure-controlled air to the divert gates, pushers and bag-sealing cylinders on a packaging conveyor, with the psi gauge letting operators set and verify line pressure at a glance.
Conditioning shop air for a test bench or lab rig that needs particulate-free air at a stable, lower-than-standard pressure, with the check valve holding the setting if supply pressure dips.
Size 200 with a 1/4 in NPT port suits lines whose air consumption sits within the GFR200 flow curve; if your demand is higher, step up to the 300, 400 or 600 size rather than oversizing the element. The 5 um grade (W) is the right choice when downstream valves, cylinders or instruments need finer filtration than the standard 40 um element; note that the finer element loads faster, which matters more with this unit's manual drain, since the bowl is drained by hand rather than automatically. The low-pressure regulator type is intended for circuits that work below the standard regulator's range - the exact adjustment range for this type is not published, so confirm it with us. The fitted square gauge reads in psi; MPa or bar scales and an external round gauge are alternatives. PT is the standard thread and G or NPT are catalogue options to order, and a bracket is included for panel or surface mounting.
Because flow is published only as curves and not as a single rated figure, ask us to confirm sizing against your application before you order.
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 only as performance curves, not as a single rated figure, so we do not quote a l/min or SCFM number. Send us your application's air consumption and working pressure and we will confirm the datasheet curve and confirm this 200-size, 1/4 in unit is the right step before you order.
The M in the code specifies a manual drain: condensate collected in the polycarbonate bowl is released by hand rather than automatically. That keeps the unit simple, but the bowl should be checked and drained as part of routine maintenance, especially on lines with heavy moisture load. If you would rather not drain by hand, the GFR series is also available with automatic or differential-pressure drains.
