The AirTAC GFR200-08 AirTAC Filter Regulator NPT1/4 5 um Low-Pressure 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 removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is built with a 1/4 in NPT port, a fine 5 um filter element, a manual drain on the polycarbonate bowl, and the low-pressure regulator type, so it suits circuits that run at reduced working pressure rather than full line pressure. A round pressure gauge scaled in psi is fitted for direct setpoint reading, and the unit is supplied without a mounting bracket.
This is a genuine AirTAC part from the G-series range, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and options including automatic, manual or differential-pressure drains, 40 um or 5 um filtration, square or round gauges with MPa, psi or bar scales, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so we confirm the datasheet and sizing figures 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. 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". |
| M | Drain: Manual drain — this also sets the regulating band (0.05 - 0.9 MPa (7 - 130 psi)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| J | Supplied without bracket. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. C is round, F is square. |
| 2 | Gauge scale: psi. 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.

On a fixture-clamping manifold that runs at reduced working pressure, the GFR200-08 filters the supply air to 5 um and holds the regulator setpoint, with the fitted psi gauge giving the operator a direct pressure readout at the clamp station.
At the air inlet of a carton-sealing or wrapping machine, this 1/4 in filter regulator strips water and fine particles before the machine's control valves, and the manual-drain bowl is emptied during scheduled changeover cleaning.
At a workbench drop feeding air tools and small cylinders, the GFR200-08 combines fine 5 um filtration with low-pressure regulation in one body, keeping the drop compact while the round psi gauge lets each operator set and verify their own pressure.
Choose the size by port and expected flow: this GFR200 unit steps up to GFR300, GFR400 and GFR600 with larger ports for higher demand. Drain type is a real choice: manual drain (as fitted here) needs periodic bowl draining, while automatic and differential-pressure drains discharge condensate without operator attention. Filter grade is 40 um standard or 5 um fine (this unit is 5 um, code W). Gauges can be embedded square or external round, scaled in MPa, psi or bar; thread can be PT (standard), G or NPT; and a bracket can be ordered where this no-bracket version does not fit. Flow is published as curves, not a single rating, so 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 rather than a single rated figure, so we do not quote one number here. Tell us your application and we will confirm the flow and sizing from the datasheet on request before you order.
This configuration is coded M for a manual drain, which means condensate collected in the polycarbonate bowl is released by hand at intervals. The GFR family is also available with automatic or differential-pressure drains, and we can quote that variant if you prefer unattended drainage.
