The AirTAC GC400C15LF2GK 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 AirTAC GC series is a three-unit F.R.L. combination: a separate filter, regulator and lubricator assembled as one set, so compressed air is cleaned of water and particulate, reduced to the working pressure, and carried with an oil mist to downstream equipment. This GC400C15LF2GK is the size 400 unit with a G1/2 (BSPP) port, a 40 um filter element, a differential-pressure drain on the filter bowl and a metal bowl. The regulator is the low-pressure type, and the set includes an embedded square gauge with a psi scale, a reverse (check) valve and a mounting bracket.
This is a genuine AirTAC part. The GC family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, and options that include automatic or manual drains, a 5 um filter element (code W), gauge scales in MPa, psi or bar, and G or NPT threads in place of the PT standard. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures 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.

Conditioning the branch off the plant ring main that feeds the cylinder and valve bank group on a carton forming, filling and sealing line, so the machine sees clean, regulated, lubricated air.
Supplying the clamp cylinders and swing clamps on a CNC fixture, with the set handling water and swarf carryover, pressure reduction and tool-way lubrication at one drop.
Feeding impact wrenches and pneumatic nutrunners at a commercial-vehicle assembly bay, where the lubricator section keeps tool motors oiled through the shift and the regulator sets the tool circuit pressure.
The real choices in this family are the size and port step (200/300/400/600, 1/8 in to 1 in) matched to the air demand of the line; the drain type on the filter bowl (differential-pressure as here, automatic, or manual); the filter grade (40 um standard, 5 um with code W); the gauge scale (MPa, psi or bar); the thread (PT standard, with G or NPT to order); and whether a bracket is fitted. This unit carries the L code for the low-pressure regulator type, whose adjustment range differs from the standard type and is not published - confirm the exact range with us before ordering. Flow is published as curves, not a single rating, so send us your air demand and we will confirm sizing against the datasheet before you order.
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 GC series as curves, not as a single rated figure, so we do not quote a number here. Tell us your line pressure and air demand and we will confirm the sizing from the datasheet on request.
The L in the code marks the low-pressure regulator type, whose adjustment range differs from the standard type and is not published - confirm the exact range with us. The F2 code sets the embedded square gauge to a psi scale; MPa or bar scales, and an external round gauge, are available as options.
