The AirTAC GFR30015LF2WG AirTAC Filter Regulator G1/2, 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 PT1/2" 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 GFR30015LF2WG is a 300-size filter regulator that removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration has a G1/2 (BSPP) port, a 5 um filter element (the finer W grade, versus the 40 um standard), a differential-pressure drain that bleeds condensate automatically as flow passes through, a low-pressure regulator type, and an embedded square gauge reading in psi. The polycarbonate bowl lets you see the condensate level, and a mounting bracket is included.
This is a genuine AirTAC part. The GFR series is available in sizes 200, 300, 400 and 600 with a full range of port sizes, drain types, filter grades, gauge scales and thread options (PT standard, G and NPT to order). Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so ask us to confirm sizing and datasheet figures for your application.

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.

On a fixture line where clamp cylinders are set to a gentle holding pressure below the main supply, this low-pressure filter regulator cleans the air and holds the reduced setting, with the psi gauge giving the setter a direct readout at the cell.
Light-duty cylinders and air-jet functions on textile looms and carton-closing machines run best on cleaned, reduced-pressure air. The 5 um element protects the small valve seats downstream, and the differential-pressure drain keeps condensate moving out without a manual walk-round.
Blow-off nozzles and diverter cylinders along a conveyor line need filtered air at a stable reduced pressure. This unit mounts on the bracket at the station, its polycarbonate bowl shows condensate at a glance, and the square psi gauge lets line staff verify the setting without tools.
Size and port step up from 200 through 600, with larger sizes carrying larger ports and more flow - match the step to your line's air demand rather than oversizing on guesswork. This unit is already set to the 300 size with a G1/2 port. The 5 um element here suits points where finer particulate matters; the 40 um standard grade is the economical choice for general upstream protection. Drain choice is differential-pressure (fitted here, self-bleeding with flow), automatic, or manual. Gauge scale can be MPa, psi or bar - this one reads psi - and an external round gauge is available as an option. Thread is PT as standard with G and NPT as order options; this unit is specified in G. A bracket is included.
Because flow is published as curves and not a single rated figure, send us your application details and we will confirm sizing against the datasheet before you order. The exact regulation range of the low-pressure type is not published as a single figure either - we will confirm it on request.
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 number, so we do not quote a figure here. Send us your line pressure, downstream demand and port size, and we will confirm the sizing from the datasheet on request before you order.
W is the filter-grade code: this unit carries the 5 um element instead of the 40 um standard, so it strips finer particulate. The rest of the code decodes as a 300-size, G1/2 G-thread port, low-pressure regulator type, square gauge with psi scale, differential-pressure drain, bracket included, and no reverse/check valve.
