The AirTAC GFR200-08 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 AirTAC GFR200-08 is a filter regulator: water and particulate removal plus downstream pressure regulation combined in one compact body. This size 200 unit is fitted with 1/4 in NPT ports, a 5 um filter element for finer filtration than the 40 um standard, a manual drain for controlled bowl emptying, and a round pressure gauge scaled in MPa. The standard regulator covers 0.05-0.9 MPa (7-130 psi), maximum inlet pressure is 1.0 MPa (145 psi), and the polycarbonate bowl suits non-freezing compressed air from -5 to 70 C. A mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and is available with 40 um or 5 um elements, differential-pressure, automatic or manual drains, square or round gauges scaled in MPa, psi or bar, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so contact 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. |
| (blank) | Mounting bracket included. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. C is round, F is square. |
| 1 | Gauge scale: MPa. 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.

Feeding filtered, regulated air to the tool-change and clamping circuits of a CNC machining centre, where the 5 um element protects sensitive valves from fine particulate and the MPa gauge gives operators a direct setpoint check.
Conditioning the air feeding the cylinders on a carton sealing machine, with the manual drain emptied at shift start as part of the line's daily maintenance routine.
Supplying clean, regulated air to pneumatic positioners and valve actuators on a process skid, where the compact single-body GFR layout saves panel space over separate filter and regulator units.
Size up by port and required flow: this 200-size unit carries 1/4 in NPT ports, and stepping to 300, 400 or 600 buys larger ports and more flow capacity. Choose the drain to match maintenance practice: manual (this model) for scheduled draining, automatic or differential-pressure where the bowl should clear itself. The 5 um element here suits finer air preparation; the 40 um standard grade remains available. Gauge scale (MPa, psi or bar), thread (PT standard, G or NPT to order) and bracket options are all decodable choices.
Because AirTAC publishes flow as curves rather than a single rated figure, we do not quote a flow number here. Ask us to confirm sizing against your application and we will supply the datasheet curve before you order.
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 rather than a single rated figure, so we do not state a flow number. Contact us with your application details and we will confirm the datasheet flow curve for this 1/4 in, 5 um configuration on request.
The M in the code GFR20008MC1WT specifies a manual drain: the bowl is emptied by hand on a schedule. The GFR family also offers automatic and differential-pressure drains that clear the bowl without operator action; those are separate model codes you can order if unattended draining suits your installation better.
