The AirTAC GFR20006MLF3WTK AirTAC Filter Regulator 1/8 NPT 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 PT1/8" 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 GFR20006MLF3WTK is an AirTAC GFR200 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one compact body. This configuration is the 200 size with a 1/8 in NPT port, the fine 5 um filtration grade (W), a manual drain, and the low-pressure regulator type. It comes with the embedded square gauge scaled in bar, a reverse/check valve fitted, and a mounting bracket included. The polycarbonate bowl lets you see accumulated condensate at a glance, and the manual drain is emptied by hand.
This is a genuine AirTAC part. The GFR filter-regulator 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 drains, 40 um standard or 5 um fine filtration, standard or low-pressure regulation, gauge and thread options, and an optional reverse/check valve. 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. |
|---|---|
| 06 | Port size PT1/8". 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. |
| 3 | Gauge scale: bar. 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.

On a bench-top assembly fixture that holds parts with low-pressure pneumatic clamps, this filter regulator cleans the shop air to 5 um, holds the reduced circuit pressure via the low-pressure type regulator, and the check valve keeps the clamp circuit from bleeding back if supply pressure dips.
A laboratory test bench running sensitive pneumatic instruments benefits from the 5 um element stripping fine particulate and water before the air reaches the instruments, while the regulator with its bar-scaled square gauge lets a technician set and read the reduced supply pressure directly.
Feeding the pilot-air circuit of a packaging machine's control panel, this compact 200-size unit fits tight panel space, the manual drain is emptied during scheduled changeovers, and the check valve prevents backflow from the panel circuit into the main line.
Start with size and port: the 200 series with its 1/8 in NPT port suits compact circuits and small lines; step up to 300/400/600 when the application needs larger ports. Choose the drain to match access: manual (this unit) needs someone to bleed the bowl, while automatic or differential-pressure drains discharge condensate without attention. This unit carries the 5 um (W) element for finer filtration; the 40 um standard element is the default choice where only coarse protection is needed. The square gauge is scaled in bar here; MPa and psi scales are available, and an external round gauge is optional. Thread is NPT on this code; PT (standard) and G are catalogue options. A bracket is included, and the reverse/check valve is already fitted. Flow for this family is published as curves, not a single rating, so 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, not as a single rated figure, so we do not quote a number here. Tell us your application and we will confirm the relevant flow and datasheet figures on request before you order.
The M in the code selects the manual drain: condensate collecting in the polycarbonate bowl is released by hand rather than automatically. It suits points that are checked on a schedule; where no one will attend the unit, choose the automatic (A) or differential-pressure (blank) drain version instead.
