The AirTAC GFR200-08MLNTK AirTAC Filter Regulator NPT1/4 Low-Pressure is a genuine G-series filter regulator: water separation, 40 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 GFR200-08MLNTK is a size-200 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is 1/4 in NPT thread, carries a 40 um standard filter element, and uses a manual drain, so condensate is released by opening the bowl drain at a chosen interval. It is the low-pressure regulator type and is supplied with a built-in reverse (check) valve and a mounting bracket; no gauge is fitted in this code.
This is a genuine AirTAC part. The GFR range spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and options for automatic or differential-pressure drains, a 5 um element, gauges and G/NPT threads. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures 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.
| 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. |
| (blank) | Mounting bracket included. |
| N | No pressure gauge (N). |
| (blank) | Gauge shape: Factory standard. C is round, F is square. |
| (blank) | Gauge scale: Factory standard. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 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.

Feeds filtered, regulated air to clamp actuators on a carton-sealing station, holding a gentle low-pressure setting so delicate packs are gripped without damage; the manual drain lets operators clear condensate at shift end.
Conditions air for diverter and stopper cylinders on a sorting conveyor: the 40 um element keeps water and debris out of valves, and the built-in check valve holds the downstream setting when upstream supply dips.
Suits laboratory and pilot test rigs that need lightly regulated compressed air for instruments and small actuators, with filtration upstream of sensitive components and a bracket for tidy panel mounting.
Size and port step up with required flow: this is size 200 with a 1/4 in NPT port, the compact end of the GFR range. Drain type is a real choice: manual (this code) needs a routine drain action, while automatic and differential-pressure drains clear the bowl without operator input. Filter grade is 40 um standard here; specify code W for the 5 um element where finer protection matters. This is the low-pressure regulator type, and no gauge is fitted - an external round gauge with MPa, psi or bar scale can be ordered. Thread is NPT here; PT is standard and G (BSPP) is also a catalogue option, and a bracket is included.
Because flow is published as curves rather than a single rating, and the exact regulation range of the low-pressure type is not stated in the catalogue, ask us to confirm sizing and figures 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. Tell us your application and we will confirm the flow and datasheet figures for this exact model on request before you order.
Manual drain means condensate collected in the PC bowl is released by opening the drain when you choose, rather than automatically. Code N means no gauge is fitted, so you read the setting on your own downstream gauge or order an external round gauge with an MPa, psi or bar scale as an option.
