The AirTAC GFR30015ALF2WG 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 automatic 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 GFR30015ALF2WG is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single GFR300 body, so one unit does the job of a separate filter and regulator. This configuration is built around a G1/2 (BSPP) port, a 5 um filter element for finer particle capture than the standard 40 um grade, and an automatic drain that expels collected condensate from the polycarbonate bowl without anyone opening it. It is the low-pressure type, and the embedded square gauge reads in psi so operators can check and adjust the setting at a glance. A mounting bracket is included for panel or frame fixing.
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 to 1 inch, and options including manual or differential-pressure drains, a 40 um standard element, alternative gauge scales and PT or NPT threads. Full datasheet and flow figures are published as curves rather than a single rating, so ask us to confirm the numbers 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.

On a fixture line where clamp cylinders need clean, moisture-picked air and a steady, lower-than-line pressure setting, this filter regulator conditions the supply and lets operators dial in the clamp pressure while the psi gauge confirms it.
At a paint or coating booth running at reduced pressure, the low-pressure type regulator sets a gentle working pressure for the spray guns while the 5 um element keeps fine particles out of the finish air.
On a cartoning or wrapping line with air cylinders and actuators working unattended, the automatic drain clears condensate from the bowl on its own and the regulator holds the machine's working pressure without daily drain rounds.
Start with the port step: GFR300 carries 1/2 inch ports, and the G-series ladder runs from size 200 (1/8-1/4 inch) up to size 600 (1 inch), so step up a size if your line flow demands it. This unit pairs an automatic drain (best where the unit sits in an out-of-the-way spot or you want condensate handled without routine attention) with the 5 um W-grade element, the finer of the two published grades; choose 40 um where coarser protection is enough. The square gauge is fitted and reads psi; MPa and bar scales and an external round gauge are alternatives in the range. Thread is G (BSPP) here, with PT (standard) and NPT available as order options, and the included bracket simplifies mounting.
One honest note on sizing: AirTAC publishes flow as curves, not a single rated figure, 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 GFR300 as performance curves rather than a single rated figure, so there is no one number we can honestly quote. Send us your line pressure, working pressure and expected air demand, and we will confirm the flow figures from the datasheet for your application on request.
The W in the code specifies the 5 um filter grade, the finer of the two published options (40 um is the standard grade), so it captures smaller particles than the default element. The A specifies an automatic drain, which expels condensate from the polycarbonate bowl by itself instead of waiting for a manual drain round - useful where the unit is mounted in a spot that is awkward to reach.
