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 AirTAC GFR200-08 is a size-200 filter regulator that cleans compressed air and holds downstream pressure in one compact body. This configuration carries a 1/4 in NPT port, a 5 um filter element for finer particle removal than the standard 40 um grade, and a manual drain you operate by hand to clear collected water from the PC bowl. The regulator adjusts from 0.05 to 0.9 MPa (7-130 psi) and no gauge is fitted, so add a separate gauge if you need a visible setpoint.
This is a genuine AirTAC part. The GFR series runs from size 200 to 600 with port options from 1/8 to 1 in in PT, G or NPT thread, with drain, filter grade, gauge and mounting choices to match. 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. |
| 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.

Cleaning and regulating the supply at individual workstations on an assembly floor, where the 5 um element protects hand tools and cylinders from finer particles and the regulator holds a steady working pressure.
Feeding cleaned, regulated air to the pneumatic cylinders and grippers on a packaging or cartoning line, with the manual drain cleared during scheduled line checks.
Conditioning shop air for laboratory benches and test rigs where a compact 1/4 in unit filters water and particulate and lets the operator dial in a repeatable supply pressure.
Size 200 with a 1/4 in NPT port suits compact supply drops and point-of-use setups; step up to sizes 300, 400 or 600 when the circuit demands larger ports. The 5 um element (code W) is the right pick when downstream valves or instruments need finer filtration than the standard 40 um grade. Manual drain means an operator opens the bowl drain during checks - choose automatic or differential-pressure drain types if the unit sits where routine draining is impractical. No gauge is fitted in this code, and no mounting bracket is included. PT is the standard thread; G and NPT are catalogue options ordered by suffix. Flow for this series is published as curves, not a single rated figure, so send us your air demand and we will confirm sizing against the datasheet 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, not as a single rated figure, so we do not quote a l/min or SCFM number. Tell us your application and air demand and we will confirm the relevant datasheet figures on request before you order.
In the code GFR20008MJNWT, M selects the manual drain - you open it by hand to expel collected water - and N means no gauge is fitted. If the unit will be hard to reach, ask about automatic or differential-pressure drain versions, and add a gauge where a visible setpoint is needed.
