The AirTAC GC30008ALF2WK AirTAC F.R.L. Combination, PT1/4, 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 GC30008ALF2WK is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one set. This configuration is built around a PT1/4 (1/4 in) port in the 300 size. The filter element is the fine 5 um grade (the standard grade is 40 um) and the bowl drains automatically, so collected water is expelled without manual attention. The regulator is the low-pressure type, and a square gauge scaled in psi is fitted so the set-point can be read directly. A reverse/check valve is fitted, and a mounting bracket is included. The filter and lubricator bowls are polycarbonate (PC); only the 600 size uses aluminium alloy bowls.
This is a genuine AirTAC part. The GC family is offered in sizes 200, 300, 400 and 600 with matching port sizes, and options include thread type (PT standard, with G and NPT as order options), drain type, filter grade, gauge scale and reverse/check valve. Flow is published as curves rather than a single rated figure, so ask us to confirm the 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. 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.

Feeding a bank of pneumatic screwdrivers and clamps on an assembly line: the filter removes water and fine particulate, the low-pressure regulator holds the circuit set-point, and the lubricator mists oil to the tools.
Supplying the air cylinders that index and divert product on a packaging conveyor, where clean, lubricated air at a stable low pressure keeps the actuators cycling through the shift.
Mounted on the bracket at a CNC machine tool's pneumatic panel: 5 um filtration ahead of the regulator and lubricator protects valves and cylinders fed from the same PT1/4 supply.
Size and port step up together: 200/300/400/600, with this unit at 300 and PT1/4. Choose the size whose flow curve covers your demand - we can check the curve against your application on request. Drain choice matters: automatic drain (this unit) suits unattended duty, while manual and differential-pressure drains are also available in the family. Filter grade is 5 um here (code W) versus the 40 um standard - pick 5 um where downstream equipment needs finer water and particulate removal. The regulator is the low-pressure type; gauge scale options are MPa, psi (fitted here) or bar. Thread is PT as standard, with G (BSPP) and NPT as order options. A mounting bracket is included, and the reverse/check valve (code K) is fitted on this unit.
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 this family as curves, not as a single rated figure, so we do not quote a number here. Tell us your application and we will confirm the datasheet flow figures for the GC300 size and PT1/4 port on request, so you can size the unit correctly before ordering.
The W code in GC30008ALF2WK selects the 5 um element instead of the 40 um standard, for finer removal of water and particulate ahead of the regulator and lubricator. The A code selects the automatic drain, which expels collected condensate on its own instead of waiting for a manual drain. Both are standard catalogue options across the GC family.
