The AirTAC GC400C15LC2WG 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 GC400C15LC2WG is an AirTAC GC-series three-unit F.R.L. combination: a separate filter, regulator and lubricator that remove water and particulate from compressed air, hold a set downstream pressure and add oil mist for pneumatic equipment. This size 400 unit is threaded G1/2, carries the 5 um filter element (code W, against the 40 um standard), a differential-pressure drain on the filter bowl, a low-pressure regulator and a round external gauge reading in psi. The filter and lubricator bowls are polycarbonate, a mounting bracket is included, and no reverse/check valve is fitted.
It is a genuine AirTAC part. The GC line spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, and each unit can be ordered with a different drain type, filter grade, gauge style and scale, thread (PT is the standard; G and NPT are order options) and bracket choice. This configuration is rated to 1.0 MPa (145 psi) maximum inlet pressure and -5 to 70 C (non-freezing). The low-pressure regulator's exact adjustment range is not published, and flow for the series is published as curves rather than a single rating, so ask us to confirm the figures from the datasheet for your application.

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 spray guns and air motors on a paint line, where the 5 um element keeps water and particulate out of the finish, the regulator holds a steady set pressure and the lubricator oils the gun seals.
Conditioning the air feeding a machining centre's pneumatic clamps, tool changes and coolant sprays: a filtered, regulated supply with oil mist for the cylinders and valves.
Supplying the pneumatic cylinders and grippers on a carton packing conveyor, where clean, pressure-stabilised and lubricated air keeps seals and directional valves working over long shifts.
Size and port step up together across 200, 300, 400 and 600, with this 400 size carrying a 1/2 inch port - choose the size whose flow curve covers your demand rather than port size alone, and ask us to confirm the curve against your application before ordering. The real choices on this family are: drain type on the filter (differential-pressure as fitted here, automatic, or manual), filter grade (40 um standard or 5 um with code W, fitted here), gauge (embedded square as standard, external round optional, in MPa, psi or bar scales - this unit has the round psi gauge), thread (PT is the standard; G and NPT are order options) and bracket. This is the low-pressure regulator type, whose adjustment range is not published, so confirm it with us if your set pressure sits below the standard range.
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 series as curves, not as a single rated figure, so we do not quote a number here. Tell us your working pressure and air demand and we will confirm the sizing from the datasheet before you order.
The W in the code selects the 5 um element instead of the 40 um standard - the right choice where finer particulate removal matters, such as coating or instrumentation air. The same size 400 GC combination can be ordered with the 40 um grade if your line does not need the finer element.
