The AirTAC GFR20008MNWT 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 GFR20008MNWT is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is the 200 size with a 1/4 in NPT port, a 5 um filter element, a manual drain and a polycarbonate (PC) bowl, and it is supplied without a gauge. The standard regulator covers 0.05-0.9 MPa (7-130 psi), max inlet pressure is 1.0 MPa (145 psi), and the operating temperature range is -5 to 70 C (non-freezing). With the manual drain, accumulated condensate is vented by hand as part of routine checks.
This is a genuine AirTAC part. The GFR series spans sizes 200, 300, 400 and 600 with port options from 1/8 to 1 in, drain choices (differential-pressure, automatic or manual), 40 um standard or 5 um elements, gauge and thread options, and bracket choices. Flow figures are published as curves rather than a single rating, so ask us to confirm sizing or send the datasheet for this model.

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. Standard type, regulating 0.05 - 0.9 MPa (7 - 130 psi). 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)). |
| (blank) | Standard 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. |
| 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.

Air supply to workholding clamps and tool-change cylinders on a CNC machining center: the 5 um element protects downstream valves from water and debris while the regulator holds the set clamp pressure.
One filter regulator per zone on a packaging conveyor keeps condensate out of the divert and stopper cylinders and lets each zone run its own pressure; the manual drain suits a daily operator check.
Air to spray guns in a paint or coating booth: the 5 um element supports cleaner finishing air and the regulator sets the gun supply pressure, with the manual drain bled during end-of-shift checks.
The real choices on this family are the size and port step against your air demand, the drain type (manual here, with automatic and differential-pressure available), the filter grade (40 um standard or 5 um as on this unit), the gauge and its scale, and the thread (PT is the standard; G and NPT are order options). A mounting bracket is included on this model. Flow 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. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes GFR-series flow as curves rather than a single rated figure, so we do not quote a number here. Tell us your application and we will confirm the sizing from the datasheet on request.
M is the manual drain, so condensate is vented by hand as part of routine checks (automatic and differential-pressure drains are available in the series). W selects the 5 um element instead of the 40 um standard. Max inlet pressure is 1.0 MPa (145 psi), the regulator range with manual drain is 0.05-0.9 MPa (7-130 psi), and the temperature range is -5 to 70 C.
