The AirTAC GC30008ALC2W AirTAC F.R.L. Combination 1/4 in, 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 GC30008ALC2W is a genuine AirTAC three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one GC300 set. This configuration is built for a 1/4 in PT port. The filter element is the fine 5 um grade (the W option, versus the standard 40 um), the bowls are PC (polycarbonate) at this size, and the drain is the automatic type, so condensate is expelled without manual attention. The regulator is the low-pressure type, and the unit carries a round gauge with a psi scale; the embedded square gauge is the standard fitting, with the external round gauge as the ordered option here. A mounting bracket is included.
This is a genuine AirTAC part from the GC series, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in up to 1 in, and options for thread type (PT standard, G and NPT to order), drain type, filter grade, gauge style and scale. Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing). Flow is published as curves rather than a single rated figure, so we confirm flow and datasheet figures 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. 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.

Feeds the cylinders and control valves of a bench or gantry press with filtered, regulated and lubricated air, with the 5 um element protecting tight-tolerance valve spools and the automatic drain handling condensate build-up through long shifts.
Conditions the supply air to a lab rig or test bench where fine particulate (5 um), stable low-pressure regulation and a psi-reading gauge are needed, and the lubricator meters oil mist to downstream air tools and actuators.
Sits at the drop of a packaging or conveyor line to clean, regulate and lubricate the air driving diverters, lifters and gripper cylinders, with the automatic drain keeping moisture out of the circuit during continuous production.
Start with the size and port: this is size 300 with a 1/4 in PT port; step up to 400 or 600, or down to 200, if your line's flow demand points elsewhere - flow is published as curves, not a single rating, so ask us to confirm sizing against your application before ordering. The 5 um element (code W) suits air that feeds sensitive valves and instruments; choose the standard 40 um where only coarser protection is needed. The automatic drain keeps condensate off your floor without daily attention; manual and differential-pressure drains are the other catalogue choices. The regulator here is the low-pressure type - confirm its exact adjustment range with us, as it is not published in the standard table. The round gauge reads in psi; square gauges and MPa or bar scales are alternatives. PT is the standard thread, with G (BSPP) and NPT available as order options, and a mounting bracket is included with 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 the GC series as curves rather than a single rated figure, so no single l/min or SCFM number can be quoted honestly. Tell us your line pressure and the flow your actuators need, and we will confirm the correct size against the datasheet curves on request before you order.
This GC30008ALC2W carries the L low-pressure regulator option, so it is set up for circuits running at reduced pressure rather than full line pressure; its exact adjustment range is not published in the standard table, so confirm it with us. The A in the code is the automatic drain: the filter bowl expels collected condensate on its own, with no manual draining, and the W gives the fine 5 um element instead of the standard 40 um.
