The AirTAC AirTAC GC30008ALF2WG F.R.L. Combination G1/4 5 um is a genuine G-series three-unit F.R.L. combination: a separate filter, a separate regulator and a separate lubricator assembled as one air-preparation station. It has PT1/4" ports, a 5 µm element, a automatic drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The AirTAC GC series is a three-piece F.R.L. combination: a separate air filter, pressure regulator and lubricator assembled into one supply unit that cleans, regulates and lubricates compressed air. This GC30008ALF2WG is the 300 size with G1/4 (G/BSPP) ports, a 5 um filter element (code W), an automatic drain on the filter bowl, the L low-pressure regulator type, an embedded square gauge reading in psi, and no reverse/check valve. Maximum inlet pressure is 1.0 MPa (145 psi), the polycarbonate bowls suit the -5 to 70 C non-freezing operating range, and a mounting bracket is included.
This is a genuine AirTAC part. The GC range is published in 200, 300, 400 and 600 sizes with ports from 1/8 to 1 in, and with choices of drain type, filter grade, gauge scale, thread form and regulator type. Flow for this series is published as curves rather than a single rating, so ask us to confirm sizing and any datasheet figure against 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. The combination has no separate bracket code — the three units couple together with their own mounting hardware. 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, gauge, shape, scale, grade, thread, reflux — there is no bracket position on a combination. Constituent units, orderable separately as spares: GF300-08 filter, GR300-08 regulator and GL300-08 lubricator.
A GC is three separate units, so the filter and the regulator can each be serviced or replaced on their own. A GFC is the two-unit set, where filtering and regulating share one body — shorter, but the two functions come as one part. Both filter, regulate and lubricate.

Clean, regulated and lubricated air for pneumatic clamps, tool changers and chip-blow nozzles on a machining centre. The 5 um element protects precision valves, and the low-pressure regulator type suits circuits that run below standard line pressure.
A single supply point feeding the cylinders and actuators on a carton-forming and sealing conveyor. The automatic drain clears condensate without operator attention on lines that run across shifts, and the lubricator mists oil to the air cylinders downstream.
Filtered, regulated and lubricated air at an automotive or furniture assembly station running impact drivers, ratchets and air cylinders. The square psi gauge gives operators a clear setpoint readout, and the included bracket mounts the set at the bench.
Size drives port and flow capacity: this unit is size 300 with G1/4 ports - step up to 400 or 600 where air demand is larger. The filter carries the 5 um element (W) instead of the 40 um series standard; choose 5 um where downstream valves and cylinders need finer particulate removal. Drain is automatic, so condensate is discharged from the filter bowl without manual attention; manual and differential-pressure drains are alternatives in the series. The regulator is the L low-pressure type - its exact adjustment range is not published in our validated data, so confirm it with us for your circuit. The gauge is the embedded square type reading psi, with MPa and bar scales available as options. This model is specified with G (BSPP) thread; PT is the series standard thread and NPT is an orderable option. Flow is published as curves, not a single rating - ask us to confirm sizing against the application before ordering.
Quick checklist
The PC bowls must not be cleaned with solvents — wipe them with a dry cloth. The lubricator adds an oil mist downstream of the regulator. If any branch of the line must stay oil-free, take that branch off before the lubricator, or use a GR300-08 regulator with a GF300-08 filter on that branch.
AirTAC publishes flow for the GC series as curves rather than a single rated figure, so we do not quote a number here. Send us your line pressure, port size and air demand, and we will confirm the flow curve and correct sizing from the datasheet on request.
The A in the code fits the automatic drain: condensate collected in the filter bowl is discharged without anyone opening it, which suits unattended or multi-shift lines. The series also offers manual drain (code M) and the differential-pressure drain that is the series default - tell us which matches your maintenance routine and we will confirm the variant.
