The AirTAC GC400C10MLF2G AirTAC F.R.L. Combination G3/8 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 GC400C10MLF2G is a three-unit F.R.L. combination that conditions compressed air in three separate stages: a filter that removes water and particulate, a pressure regulator, and an oil-mist lubricator for downstream air tools and cylinders. This size 400 set is built with G3/8 ports (G/BSPP thread), a manual drain on the filter bowl, a 40 um standard filter element, a low-pressure regulator type, and an embedded square gauge reading in psi. No reverse/check valve is fitted. 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 series is available in sizes 200, 300, 400 and 600, with a choice of port sizes and thread types (PT standard; G and NPT as order options), drain types, filter grades (40 um standard, 5 um optional), gauge scales and low-pressure or standard regulator types. Flow figures for this series are published as curves rather than a single rating, so ask us to confirm the datasheet and sizing 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.

Installed at the drop from a compressed-air ring main to condition the supply feeding a production bay: water and dirt removed, pressure set for the cells downstream, and oil mist carried to the air tools on the line.
Mounted on the air supply of packaging machinery where cylinders, grippers and blow-off nozzles run continuously - clean, regulated and lubricated air keeps the actuators moving through long shifts.
Fitted ahead of clamps, tool-changers and air-powered fixtures on a machining centre, where the low-pressure regulator type lets the circuit be set below the normal range and the psi gauge gives a direct local reading.
Start with the size and port: the 400 frame with G3/8 ports sits in the middle of the GC range (200/300/400/600), so step up or down according to the air demand of the line - larger sizes carry larger ports and more flow. This unit has a manual drain, which suits points of use that are attended regularly; choose automatic or differential-pressure drain codes where the bowl cannot be drained by hand. The 40 um element is the standard grade; specify the W code for a 5 um element where finer filtration is needed. The fitted square gauge reads in psi; MPa and bar scales and an external round gauge are alternatives. Thread is G (BSPP) here, with PT as the standard and NPT available to order.
Because flow for this series is published as curves and not as a single rated figure, we do not quote a flow number here - send us your application details 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 rather than a single rated figure, so we do not state a flow number, Cv or SCFM value here. Send us your line pressure and air demand and we will confirm the sizing from the datasheet on request before you order.
The M code in GC400C10MLF2G specifies a manual drain on the filter bowl: collected water is emptied by hand, which suits attended points of use. If the installation is unattended or access is difficult, the same size is available with automatic (A) or differential-pressure (blank) drain codes - ask us for those variants.
