The AirTAC GC30008ALC2WK AirTAC F.R.L. 3-Unit, 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 GC30008ALC2WK is an AirTAC GC-series three-unit F.R.L. combination: a separate filter, regulator and lubricator assembled as one complete air-treatment set. This configuration is built on the GC300 size with a PT1/4 (1/4 in) PT-threaded port. The filter element is the fine 5 um grade (code W) for cleaner air than the standard 40 um element, and the drain is automatic (code A), so condensate is expelled without manual attention. The regulator is the low-pressure type (code L), and a round gauge with a psi scale (code C2) is fitted so the set-point can be read directly. A reverse/check valve (code K) is also fitted, and the mounting bracket is included.
This is a genuine AirTAC part. The GC family is offered in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and with choices of drain type, filter grade, gauge style and scale, thread (PT standard, with G and NPT as order options), and reverse valve. Flow figures are published as curves rather than a single rating, so we confirm the datasheet and sizing 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.

Feeding filtered, regulated and lubricated air to the tool-clamp and pallet-change circuits of a machining centre, where the 5 um element protects fine valves and the psi gauge lets setters verify the set-point.
Conditioning the air feeding cylinders and grippers on a carton-forming and sealing conveyor, with automatic drain keeping condensate out of the line during multi-shift running.
Supplying treated air to spray guns and air-assisted applicators, where the 5 um grade, low-pressure regulation and oil-mist lubrication support consistent finish work at the booth.
Sizing starts with the size/port step: GC300 with a PT1/4 port sits in the middle of the range (200/300/400/600), so step up to GC400 or GC600 if the line demands more flow, or down to GC200 for compact points of use. Because flow is published as curves and not a single rated figure, ask us to confirm sizing against your application before ordering. This unit already carries the fine 5 um element (W), automatic drain (A), low-pressure regulator (L), round psi gauge (C2) and reverse valve (K); the standard alternatives are a 40 um element, differential-pressure or manual drain, an embedded square gauge with MPa/psi/bar scales, and a standard regulator. Thread is PT as standard; G (BSPP) and NPT are catalogue options to order. A mounting bracket is included with this set.
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 number, so we do not quote a rated flow, Cv or SCFM figure. Tell us your line pressure and the flow your application needs, and we will confirm the sizing against the datasheet curves on request before you order.
A = automatic drain (condensate expelled without manual attention, instead of the default differential-pressure drain); L = low-pressure regulator type; C2 = round gauge fitted with a psi scale (the embedded square gauge with MPa/psi/bar scales is the standard alternative); W = 5 um filter element instead of the standard 40 um; K = reverse/check valve fitted. Thread is PT1/4 (PT standard, with G and NPT as order options), and the mounting bracket is included.
