The AirTAC GC30008AC2WG AirTAC F.R.L. Combination, G1/4 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 GC30008AC2WG is an AirTAC GC300 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 G1/4 port, carries the 5 um (W) filter element instead of the 40 um standard, and uses an automatic drain so collected condensate is expelled without manual attention. The regulator is the standard type with a 0.15-0.9 MPa (20-130 psi) adjustment range, and the round gauge fitted here reads in psi. The polycarbonate bowl on the filter section suits this size, a mounting bracket is included, and the maximum inlet pressure is 1.0 MPa (145 psi) with a working temperature of -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GC family is available in sizes 200, 300, 400 and 600 with a step of port sizes, and each unit can be ordered with a different drain type, filter grade, gauge scale (MPa, psi or bar), thread option (PT standard, G or NPT) and reverse/check valve where the family supports it. Published flow data appears as curves rather than a single rated figure, so ask us to confirm flow or 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. Standard type, regulating 0.15 - 0.9 MPa (20 - 130 psi). 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 tool-clamp and chuck-actuation circuits on a CNC machining centre: the 5 um element protects the clamping valves from particulate and water, the regulator holds a steady setting for repeatable clamping, and the lubricator mists oil to the actuated components.
Prepares air for the pick-and-place and case-sealing cylinders on a packaging conveyor line: filtered and regulated air keeps stroke timing consistent across shifts, and the automatic drain clears condensate on a line that runs unattended.
Conditions the air feeding grippers and small actuators on a laboratory automation skid: the fine 5 um grade suits sensitive downstream components, the psi gauge matches the panel instrumentation, and the lubricator keeps moving parts coated over long duty cycles.
Start with the size and port: the GC300 with its 1/4 in port sits in the middle of the 200/300/400/600 range, and the right step depends on the air demand of the downstream circuit - if your consumption sits near the top of what a 300 can pass, step up to the 400 rather than oversizing the regulator. This unit already carries the 5 um element (code W); the 40 um standard grade is the usual choice for general cylinder supply, while 5 um suits finer downstream equipment. Drain type is a real choice: automatic (as fitted here) suits unattended installations, manual drain suits stations someone checks routinely, and differential-pressure drain is the catalogue default. Gauge scale (MPa, psi or bar) should match the gauges already on your line, and thread can be PT (standard), G or NPT to suit your fittings.
Flow for this family is published as curves, not a single rated number, so we cannot quote a rated flow figure here. Send us your application's air demand and we will confirm sizing against the datasheet curves before you order.
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, not as a single rated figure, so we do not quote a rated flow, Cv or SCFM number for this unit. Tell us the air demand of your application and we will confirm the sizing against the datasheet curves on request before you order.
The code GC30008AC2WG decodes A as an automatic drain, which expels collected condensate on its own instead of relying on someone opening a manual drain, and W as the 5 um filter element instead of the 40 um standard. Both are order-time choices: the same GC300 body is available with manual or differential-pressure drain and with the 40 um grade if your application does not need the finer filtration.
