The AirTAC GC300C08AC2WGK 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 See datasheet ports, a 40 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC300C08AC2WGK is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one complete air-treatment set. This 300-size configuration is threaded G1/4, carries the 5 um filter element (code W) for finer water and particulate removal than the standard 40 um grade, and uses an automatic drain so collected condensate is expelled without manual attention. The regulator is the standard type with a round external gauge reading in psi, and a reverse/check valve is fitted. A mounting bracket is included.
This is a genuine AirTAC part. The GC series is available in sizes 200, 300, 400 and 600 with matching port sizes, a choice of drain types, filter grades, gauge styles and scales, and PT, G or NPT threads. Flow figures for this series are published as curves rather than a single rating, so ask us to confirm the datasheet and sizing 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. 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-C0 filter, GR300-C0 regulator and GL300-C0 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 spray guns and air-assisted applicators on a paint line, where the 5 um element, regulated pressure and oil-mist lubrication keep finish quality consistent across shifts.
Supplies the cylinders and air actuator on a carton conveyor or case-packing station, with automatic drain protecting the circuit during unattended runs.
Treats the shop-air feed to pneumatic clamps, tool-changer actuators and workholding fixtures on a machining centre, where clean, regulated, lubricated air keeps repeatable clamping.
Start with the port and size step: the 300 size with its 1/4 in port suits lighter general-purpose circuits, while larger sizes serve higher-demand lines - match the step to the flow your circuit needs rather than to the port alone. Choose the drain type to suit access: automatic drain (as fitted here) suits unmanned or hard-to-reach installations, manual drain suits attended stations, and the differential-pressure default drains on a pressure drop. Select the filter grade for the duty: 40 um is the standard element and 5 um (this unit, code W) is the finer option for more sensitive downstream equipment. Pick the gauge style and scale - embedded square or external round, in MPa, psi or bar (this unit: round, psi) - and confirm the thread: PT is the standard, with G and NPT available as catalogue options. A bracket is included for panel or wall mounting.
Because flow for this series is published as curves rather than a single rated figure, ask us to confirm sizing against your application before ordering.
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-C0 regulator with a GF300-C0 filter on that branch.
AirTAC publishes flow for the GC series as curves rather than a single rated figure, so no single flow number can be quoted for this unit. Tell us your line pressure and the air demand of your circuit and we will confirm the sizing from the datasheet on request.
The A in the code sets the automatic drain, so condensate is expelled from the filter bowl without manual attention - useful for unmanned or hard-to-reach installations. The W sets the 5 um filter element, the finer alternative to the standard 40 um grade, for downstream equipment that needs cleaner air.
