The AirTAC GC300C15AC2WK AirTAC F.R.L. Combination, PT1/2 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 GC series is AirTAC's three-piece F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one air-preparation set. This configuration is size 300 with a PT1/2 (1/2 in) port. The filter element is the fine 5 um grade (W) with an automatic drain, so collected water is expelled without manual attention. The regulator is the standard type with a 0.15-0.9 MPa (20-130 psi) adjustment range, fitted with an external round gauge scaled in psi, and a reverse/check valve (K) is included. A mounting bracket is supplied, and the filter bowl on this size is polycarbonate.
This is a genuine AirTAC part. The GC family spans sizes 200, 300, 400 and 600, with port sizes from 1/8 in to 1 in, PT (standard), G or NPT threads, differential-pressure, automatic or manual drains, 40 um standard or 5 um fine filtration, and gauge scale choices of MPa, psi or bar. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures 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-C1 filter, GR300-C1 regulator and GL300-C1 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 a mixed valve-and-cylinder circuit on an assembly line: the 5 um filter cleans the supply, the regulator holds a stable set pressure, and the lubricator mists oil to the actuated tooling, all from one 1/2 in PT connection.
A packaging conveyor line with air-driven pushers and divertors: the regulator keeps cylinder speed consistent, the automatic drain protects the valves from accumulated water, and the lubricator extends cylinder seal life.
A pneumatic test bench or laboratory fixture where clean, set-pressure air is needed at the panel: the fine 5 um element and psi-scaled gauge give readable, filtered supply, with the check valve holding the set-up between cycles.
Start with the size and port: 200, 300, 400 and 600 step up in port and flow capacity, so match the step to the air demand of the downstream circuit - here size 300 with a 1/2 in PT port. Choose the drain: automatic (this unit) suits points where bowls are not checked routinely; manual suits attended installations; differential-pressure drain is the catalogue default. Choose the filter grade: 40 um is standard for general protection, 5 um (this unit, code W) for finer downstream cleanliness. Select the gauge scale - MPa, psi (this unit) or bar - and the thread: PT is the standard, with G (BSPP) and NPT available as order options. A bracket is included here. Because flow is published as curves and not as a single rated number, 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-C1 regulator with a GF300-C1 filter on that branch.
AirTAC publishes flow for the GC series as curves rather than a single rated figure, so we do not quote one number. Tell us your application and we will confirm the relevant datasheet flow figures on request before you order.
The A in the code sets the automatic drain, which expels collected water without manual attention, and the W sets the fine 5 um filter grade instead of the 40 um standard. Both are order-time choices on the GC series, along with gauge scale (MPa, psi or bar) and thread (PT standard, G or NPT to order).
