The AirTAC GFR200-08 AirTAC Filter Regulator, 1/4 in NPT, 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 GFR200-08 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 (code W), a manual-drain polycarbonate bowl, an embedded square gauge scaled in MPa, and a standard regulator with a 0.05-0.9 MPa (7-130 psi) adjustment range. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family spans 200, 300, 400 and 600 sizes with ports from 1/8 to 1 in, PT as the standard thread and G or NPT as order options, plus drain, filter-grade, gauge-scale and bracket choices across the range. Flow is published as curves rather than a single rated figure, so ask us to confirm datasheet and sizing 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). |
| F | Gauge shape: Square. 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.

Filtering and regulating the compressed air feeding solenoid valves and workholding cylinders on a machining centre, where the 5 um element and a set downstream pressure protect the valve train from water and particulate carryover.
Conditioning the air supply to pick-and-place and sealing cylinders on a packaging machine, with the gauge giving operators a visible setpoint and the manual drain allowing the bowl to be emptied during scheduled line stops.
Regulating and cleaning the air feeding pneumatic control valves and positioners on a process skid, where a stable, filtered supply downstream of the compressor is part of the instrument-air conditioning stage.
The real, decodable choices on this family are the size and port step (200/300/400/600, 1/8 to 1 in), the drain type (manual, automatic, or differential-pressure), the filter grade (40 um standard or 5 um with code W), the gauge (embedded square as standard, external round optional, MPa/psi/bar scales) and the thread (PT standard; G and NPT ordered as options). A mounting bracket is included with this unit, and the manual-drain version carries the wider 0.05-0.9 MPa (7-130 psi) adjustment range.
Flow for this series is published as curves, not a single rating, so please 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 this series as curves rather than a single rated figure, so we do not quote one number. Tell us your application and required conditions and we will confirm the datasheet and flow-curve figures on request.
M specifies a manual drain: the polycarbonate bowl is emptied by hand rather than automatically or by differential pressure. W selects the 5 um filter element instead of the 40 um standard, a finer grade chosen where downstream equipment needs cleaner air. Both are decodable choices on this family.
