The AirTAC GC30008AC2WGK AirTAC F.R.L. Combination, G1/4, 5 um Filter 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 GC30008AC2WGK is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one air-preparation set. This configuration is the 300 size with a G1/4 (1/4 in) port, G (BSPP) thread, a 5 um filter element (the finer of the two available grades), an automatic drain on the filter bowl, a fitted round gauge reading in psi, a reverse/check valve, and a mounting bracket. In use it filters water and particulate from the compressed air, holds the downstream pressure you set anywhere in the 0.15-0.9 MPa (20-130 psi) adjustment range, and adds a controlled oil mist for downstream pneumatic components.
This is a genuine AirTAC part. The GC family is offered in 200, 300, 400 and 600 sizes 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; G and NPT as order options) and check valve. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing for your application 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. 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 filtered, regulated and lubricated air to clamp cylinders on a machining fixture, with the 5 um element protecting the clamping valves and the psi gauge letting the setter verify holding pressure at the cell.
Supplies the air cylinders that push, lift and divert packs on a conveyor line, keeping water and fine particulate out of the valves while the lubricator mist reduces wear on seals and bores through long shifts.
Prepares the air at a paint booth take-off point: the 5 um grade strips water and fine dirt that would spoil the finish, the regulator holds a steady gun pressure, and the automatic drain copes with condensate without daily attention.
Start with the size and port: 300 is the mid step of the GC range (200/300/400/600), and the port here is G1/4 - step up a size if your line needs more flow, but match the published flow curves to your demand rather than guessing. This unit already carries the finer 5 um element (40 um is the standard alternative) and an automatic drain, which suits unattended installations; a manual or differential-pressure drain is available in the family if you prefer. The fitted round gauge reads in psi; embedded square gauges and MPa/bar scales are the other catalogue options. Thread is G (BSPP) here, while PT is the standard offering and NPT is also orderable. Flow is published as curves, not a single rating, so send us your application details and we will confirm sizing against the datasheet 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 rather than a single rated figure, so we do not quote a fixed number. Tell us your operating pressure and air demand and we will confirm the correct size against the datasheet on request - that way you size on real data instead of an estimate.
Both are decoded from the model code. The C2 position means the external round gauge is fitted with a psi scale (embedded square gauges and MPa or bar scales are the other catalogue options), and the A position means the filter bowl drains automatically instead of relying on a manual or differential-pressure drain - useful where the unit is not checked daily.
