The AirTAC GC400C15MLC2G AirTAC F.R.L. Combination, G1/2, Metal Bowl 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 unit. This GC400C15MLC2G is built for 1/2 in (G1/2) pipework threaded G (BSPP) - PT is the standard thread and NPT is also available to order. It carries the standard 40 um filter element with a manual drain, is set up as the low-pressure regulator type, and has a round psi gauge fitted. The filter bowl on this configuration is metal, and a mounting bracket is included. 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 range spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and can be ordered with automatic, manual or differential-pressure drains, a finer 5 um element (code W), different gauge scales, G or NPT threads and bracket options. Flow for the series is published as curves rather than a single rating, so ask us to confirm sizing and 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: 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.

Installed at the air drop feeding pallet clamps, tool-change cylinders and pneumatic fixtures on a machining centre, giving the whole cell filtered, regulated and lubricated air from one 1/2 in take-off point.
Mounted at the line drop serving conveyor cylinders, diverters and case-packing actuators on a bottling or packaging line, where a single F.R.L. station conditions air for many small actuators downstream.
Used as a branch take-off on a plant air ring main serving workstations, air tools or a paint-prep bay, adding filtration, regulation and oil-mist lubrication downstream of the compressor room.
Size 400 with a 1/2 in port sits in the upper-middle of the GC range; step up or down (200/300/400/600) to match your pipework and expected air demand - but note that flow is published as curves, not a single rating, so ask us to confirm the size against your application before ordering. The drain choice matters day to day: this unit is manual (drain by hand on a schedule), while automatic and differential-pressure drains are available on the same size. The 40 um element is standard; specify code W for the 5 um grade where finer filtration is needed. A round psi gauge is fitted here; the embedded square gauge is the standard style and MPa/psi/bar scales can be selected. Thread is PT as standard with G and NPT as orderable options, and a mounting bracket is included. The regulator on this unit is the low-pressure type; its exact adjustment range is not published, so we confirm it on request. Maximum inlet pressure is 1.0 MPa (145 psi); temperature range -5 to 70 C.
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 rather than a single rated figure, so we do not quote a number here. Send us your line pressure and expected air demand and we will confirm sizing against the datasheet on request before you order.
The M in the code specifies a manual drain: water collected in the filter bowl is released by hand, so draining needs to be part of a maintenance routine. If you would rather avoid that, the same size is available with an automatic or differential-pressure drain. This configuration also uses the standard 40 um element; code W gives the finer 5 um grade.
