The AirTAC GFR20008LF2WG AirTAC Filter Regulator G1/4, 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 GFR20008LF2WG is a low-pressure filter regulator: it removes water and particulate from compressed air and holds a reduced working pressure downstream, in a single compact body. This 200-size unit is fitted with a G1/4 (BSPP) port, a fine 5 um filter element (code W, versus the standard 40 um), a differential-pressure drain that bleeds condensate automatically as flow passes through, and an embedded square gauge reading in psi so the setpoint can be seen and adjusted at the unit. The polycarbonate bowl suits the non-freezing -5 to 70 C operating range, and a mounting bracket is included.
This is a genuine AirTAC part from the GFR series, which spans four sizes (200, 300, 400 and 600) with port sizes from 1/8 to 1 inch, a choice of differential-pressure, automatic or manual drains, 40 um or 5 um filtration, square or external round gauges in MPa, psi or bar scales, and PT, G or NPT threads. Rated flow is published as curves rather than a single figure, so ask us to confirm sizing and datasheet 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.

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 atomising air to spray guns on a finishing line: the 5 um element keeps the atomising air free of water and grit that would spoil the finish, while the low-pressure regulator holds a gentle, repeatable gun pressure on the psi gauge.
Supplying filtered, regulated air to low-pressure swing clamps and hold-downs on an assembly fixture. The square psi gauge lets the setter verify clamp pressure at the unit, and the differential-pressure drain keeps condensate out of the valve bank.
Running air knives and cleaning nozzles that blow debris off containers on a bottling conveyor. The low-pressure regulator keeps jet pressure gentle enough for labels and filled containers, and the 5 um element stops water spots from carry-over moisture.
Choose the size by the air consumption of the circuit, not just the existing pipe thread: the 200 size here carries a 1/4 inch port, and stepping up to 300, 400 or 600 gives larger ports and more flow capacity. This unit is the low-pressure type, intended where the working pressure is held well below the standard regulator range - confirm the setpoint with us if you are near the top of the low-pressure band. The 5 um element (W) suits instruments, spray atomising and other air that must be finer than the standard 40 um grade; the differential-pressure drain needs no manual attention but relies on flow to purge, so pick the automatic or manual drain option if the unit sits on a lightly loaded line. The square gauge here reads psi; MPa and bar scales are available, and an external round gauge is optional. Thread is G (BSPP); PT is the catalogue standard and NPT is orderable. 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 there is no one l/min or SCFM number we can honestly quote for this unit. Tell us your application and air consumption and we will confirm the sizing against the datasheet curves on request before you order.
The W in the code GFR20008LF2WG selects the fine 5 um filter element instead of the standard 40 um grade, and the F2 selects the embedded square gauge with a psi scale. Both are normal catalogue options: 5 um suits air feeding instruments, sprays and sensitive components, and the psi scale matches gauges already used on the machine. MPa or bar scales and an external round gauge are available if you prefer.
