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 differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 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: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This unit is the 200 size with a 1/4 in NPT port, built as the low-pressure type (code L); the exact setting range for this type is confirmed on request. It carries a 5 um filter element (code W), a differential-pressure drain on the polycarbonate bowl, and a reverse/check valve (code K) is fitted. No gauge is fitted (code N) and a mounting bracket is included. 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. GFR filter regulators are available in 200, 300, 400 and 600 sizes with ports from 1/8 to 1 in, and with choices of drain type, 40 um or 5 um filtration, gauge and scale, thread (PT standard; G and NPT to order) and bracket. Flow is published as curves rather than a single rating, so ask us to confirm the figures for your application before ordering.

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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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". |
| (blank) | Drain: Differential-pressure drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |
| L | Low-pressure 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. |
| K | Reverse-flow (reflux) valve fitted. |
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.

Set a gentle, steady supply pressure for glue heads or coating nozzles on a packaging line, with the 5 um element protecting small orifices from particles and water.
Feed a fixture-clamping circuit on a machining cell that runs at a low set pressure, with clean, regulated air keeping the clamping valves working reliably.
Filter and regulate a bench supply feeding analytical instruments or pneumatic test rigs that operate at modest pressures and need particle-free air.
Choose the size by the port and flow your line needs: 200 is the compact step with a 1/4 in port here, while 300, 400 and 600 step up in port and capacity. This code fixes the low-pressure regulator type and a 5 um element; the standard element is 40 um if finer filtration is not required. The differential-pressure drain is the default and works automatically; automatic and manual drains are alternatives on other codes. No gauge is fitted on this code - gauges with MPa, psi or bar scales are order options. Thread is NPT here; PT is the standard and G (BSPP) is also available to order. A bracket is included. Because flow is published as curves, not a single rating, send us your application and we will confirm sizing before you order.
Quick checklist
The PC bowl must not be cleaned with solvents — wipe it with a dry cloth. The reflux valve permits reverse flow 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 number here. Tell us your line pressure and the air your application needs and we will confirm the sizing from the datasheet on request.
No. The N in the code means no gauge is fitted. Gauges are order options on GFR units - an embedded square gauge or an external round gauge with MPa, psi or bar scales - so tell us which you need and we will confirm the variant.
