The AirTAC GC400C15ALC2G AirTAC F.R.L. Combination G1/2 Low-Pressure 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 GC400C15ALC2G is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one set, giving your compressed-air line filtration, regulation and lubrication in a single installation. This size 400 unit is configured with a G1/2 (BSPP) port, the standard 40 um filter element, an automatic drain on the filter bowl, and the low-pressure regulator type. A round gauge with a psi scale is fitted so the set outlet pressure can be read directly, and the mounting bracket is included for panel or wall fixing.
This is a genuine AirTAC part from the GC three-unit F.R.L. family, which is offered in sizes 200, 300, 400 and 600 with port sizes from 1/8 in up to 1 in, a choice of drain types, a 5 um optional filter element (code W), gauge style and scale options, and PT, G or NPT threads. Flow is published by AirTAC as curves rather than a single rated figure, so we confirm the datasheet and sizing 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.

Feeds spray-gun and air-balance circuits at a body or paint shop: the filter stage strips water and 40 um particulate before the regulator sets a stable low supply pressure, and the lubricator mists oil to the air tools on the line.
Serves the cylinder and actuator banks on a bottling or filling conveyor, where one point of filtration, low-pressure regulation and oil-mist lubrication keeps a whole machine section supplied from a single 1/2 in take-off.
Supplies the clamp and fixture-actuation circuit on a machining cell, holding the regulated low pressure the clamps were designed around while the lubricator carries oil mist to the valves and cylinders downstream.
Start with the port and size: this unit is size 400 with a G1/2 (BSPP) port; smaller or larger sizes in the GC family step the port and the air delivery up or down, so match the size step to the air demand of the circuit rather than to the pipe alone. Because AirTAC publishes flow as curves and not as a single rated number, ask us to confirm sizing against your application before ordering. Other decodable choices: drain type on the filter bowl (automatic as fitted here, or manual, or the differential-pressure default), filter grade (40 um standard as fitted, or 5 um with code W), gauge style and scale (this unit carries the round gauge with a psi scale; an embedded square gauge is the standard option with MPa/psi/bar scales), thread family (PT is the catalogue standard, with G and NPT as order options - this unit is ordered in G), and the mounting bracket (included on this configuration). The regulator on this unit is the low-pressure type; its exact adjustment range is not published on the sheet we transcribe from, so confirm it with us for your set pressure.
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 this family as curves, not as a single rated figure, so there is no one rated-flow number we can honestly quote. Send us your application details and we will confirm the sizing from the datasheet flow curves on request before you order.
The A in the code fits the automatic drain, which expels collected condensate from the filter bowl without anyone opening it - useful on lines that are not checked daily. The catalogue alternatives are the manual drain (code M) and the differential-pressure drain (blank, the default). This is a size 400 unit, so its bowl is polycarbonate; only size 600 uses an aluminium alloy bowl.
