The AirTAC AirTAC GFR200-08 Filter Regulator, PT1/4, 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 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 sets downstream pressure in one body. This 200-size unit carries a 1/4 in PT port, a 5 um filter element (the finer of the two grades), a differential-pressure drain on the polycarbonate bowl, and a fitted round gauge reading in psi. It is the low-pressure type, set up for circuits whose working pressure sits lower than a standard regulator covers; the exact setting range is confirmed on request. Maximum inlet pressure is 1.0 MPa (145 psi) and the operating temperature is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, PT as the standard thread and G or NPT as orderable options, plus choices of drain type, filter grade, gauge style and scale, and a bracket (included here). Flow is published as curves rather than a single rating, so we 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. 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.

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 clamp cylinders on a milling or turning fixture: the 5 um element keeps swarf-laden shop air clean at the clamp valves, and the low-pressure regulator holds the clamping circuit at the set pressure the fixture was designed around.
Supplying the seal-bar and jaw actuators on a bagging or wrapping machine, where the differential-pressure drain clears condensate as the line runs and the psi gauge lets operators check and reset the seal-air setting during changeover.
Conditioning the air feeding bench-top instruments, air bearings and test rigs, where the 5 um grade protects fine orifices and the low-pressure type matches circuits that run at modest settings rather than full line pressure.
Size and port step up with air demand: this 200 unit carries a 1/4 in PT port, and the 300, 400 and 600 sizes serve applications that need more flow. The 5 um W element suits air feeding finer components; the 40 um standard grade remains available if the downstream equipment tolerates it. Drain on this unit is differential-pressure, which ejects condensate while air flows; automatic and manual drains are the other catalogue choices. The fitted round gauge reads in psi, with square-gauge housings and MPa or bar scales available as options. PT is the standard thread, with G and NPT orderable, and the mounting bracket is included (J deletes it). Because flow is published as curves and not a single rating, 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.
Flow for this unit is published as curves, not as a single rated figure, so we do not quote a number here. Send us your application details - port size, downstream equipment and expected air demand - and we will confirm the datasheet flow curve and check the sizing with you before you order.
It is the low-pressure regulator variant of the GFR200: the same filter-regulator function, 1/4 in PT port and 5 um element, but set up for circuits whose working pressure sits lower than the standard type covers. The exact setting range is not published in the material we hold, so we confirm it on request.
