The AirTAC GFR200-08 AirTAC Filter Regulator NPT1/4 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 GFR200-08 is a filter regulator that removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is the size 200 unit with a 1/4 in NPT port, a 40 um standard filter element, and a manual drain you operate by hand to empty collected condensate from the polycarbonate bowl. It is the standard regulator type with no gauge fitted, so pair it with your own gauge if you need a visible setpoint.
This is a genuine AirTAC part from the GFR series, which spans sizes 200 to 600 with port options from 1/8 in to 1 in and PT, G or NPT threads, plus automatic, manual or differential-pressure drains and an optional 5 um element. 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. 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. |
| J | Supplied without bracket. |
| 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. |
| (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.

Feeding clean, regulated air to a machining centre's pneumatic tool clamps and tool-change cylinders, with the manual drain emptied during shift checks.
Conditioning and regulating the air feeding conveyor stopper cylinders and carton-forming actuators on a packaging line drop.
A point-of-use filter regulator on a factory air drop, protecting downstream valves and cylinders from water and scale while holding a set working pressure.
Start with the port step: the GFR200-08 gives you a 1/4 in NPT connection in the size 200 frame, and stepping up to GFR300, GFR400 or GFR600 buys larger ports and more flow capacity. Choose the drain to suit access: this unit is manual drain, which suits points where an operator passes regularly; automatic or differential-pressure drains suit unattended lines. The standard 40 um element covers general air preparation, while the W-suffix 5 um element is the choice where finer filtration matters. Thread is NPT here, with PT and G available to order, and the J code means no mounting bracket is supplied.
Because flow is published as curves rather than a single rated figure, 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 flow for the GFR series as curves, not as a single rated number, so we do not quote a figure here. Tell us your application and we will confirm the datasheet flow curve and sizing for the GFR200-08 on request.
The M in the code GFR20008MJNT specifies a manual drain: condensate collected in the polycarbonate bowl is emptied by operating the drain by hand. It suits positions an operator passes regularly; if the unit will sit unattended, ask about automatic or differential-pressure drain variants.
