The AirTAC GC400C15ALC2GK AirTAC F.R.L. Combination, G1/2 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 AirTAC GC series is a three-piece F.R.L. combination: a separate air filter, a pressure regulator and an oil-mist lubricator, assembled as one air-treatment set for compressed-air lines. This configuration is the GC400 size with a G1/2 (BSPP) port, an automatic drain on the filter bowl so collected condensate is expelled without manual attention, a 40 um standard filter element, a low-pressure type regulator, a round pressure gauge reading in psi, a fitted reverse/check valve, and a mounting bracket included. The maximum working (inlet) pressure is 1.0 MPa (145 psi) and the operating temperature range is -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 port options, drain types (differential-pressure, automatic or manual), a 5 um optional filter element (code W), gauge scale choices and thread options (PT standard; G and NPT orderable as specifications). Flow is published as curves rather than a single rated figure, so we confirm the datasheet and flow figures 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: GF400-C1 filter, GR400-C1 regulator and GL400-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 filtered, regulated and lubricated air to the tool-clamp and pallet-change circuits of a CNC machining center, with the automatic drain keeping condensate out of the valves during long unattended runs.
Conditioning shop air ahead of spray guns and air-assisted transfer pumps in an automotive paint booth, where the 40 um element removes water and particulate and the lubricator mists oil for downstream air motors.
Supplying treated air to the cylinders and grippers on a carton-forming and case-packing conveyor line, with the low-pressure regulator set for the actuator circuit and the psi gauge giving operators a local reading.
Start with the size and port: the GC series steps through sizes 200, 300, 400 and 600, each with its own port range, so pick the size whose flow curve covers your line demand - we can check the curve against your consumption before you order. Then set the drain: differential-pressure (default), automatic (this unit) or manual. Choose the filter grade - 40 um standard or 5 um (code W) for finer particulate. Select the gauge type and scale (MPa, psi or bar; this unit carries a round psi gauge). Pick the thread - PT is the standard, with G (BSPP) and NPT orderable as specifications - and whether a bracket is fitted (included here).
One honest note on sizing: AirTAC publishes flow as curves, not as a single rated number, so ask us to confirm the flow figures for this GC400 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 GR400-C1 regulator with a GF400-C1 filter on that branch.
AirTAC publishes flow for the GC400 as curves rather than a single rated figure, so we do not quote a rated flow number. Send us your line pressure and air consumption and we will confirm the flow figures from the datasheet for your application on request.
The L code marks the low-pressure type regulator, intended for circuits set below the standard range; the exact adjustment range is not published in the material we hold, so we confirm it on request. The A code means the filter bowl has an automatic drain, which expels collected condensate by itself instead of waiting for a manual or differential-pressure drain cycle.
