The AirTAC GC400C10MLC2K AirTAC F.R.L. Combination, PT3/8 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 GC400C10MLC2K is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator supplied as one set. This size-400 configuration is ported PT3/8 (3/8 in) with PT thread as standard. The filter section carries a 40 um element and a manual-drain polycarbonate bowl, so condensate is drained by hand on a schedule. The regulator is the low-pressure type, and this unit is specified with an external round gauge scaled in psi; a reverse (check) valve is fitted, and the mounting bracket is included.
This is a genuine AirTAC part. The GC series spans sizes 200, 300, 400 and 600, with port sizes from 1/8 in to 1 in, automatic or differential-pressure drain options, a 5 um filter element (code W), gauge scales in MPa, psi or bar, and G (BSPP) or NPT thread options to order. Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the operating 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.

Feeding a distribution manifold that serves hand tools and air cylinders across a production hall, where one set has to remove water and particles, hold a set pressure and carry oil mist downstream to the points of use.
Supplying the air-actuated clamps and blow-off points on a machining centre, keeping the regulated circuit separate from the lubricated circuit while drawing from a single compressed-air drop.
Powering the pusher and clamp cylinders on a carton packaging conveyor, where the lubricator keeps the actuator seals moving smoothly through long shifts and the manual-drain bowl is emptied at scheduled checks.
Size 400 with PT3/8 ports sits in the middle of the GC range; step to size 200, 300 or 600 when the application calls for a smaller or larger port and flow path. Drain type is a real decision: this unit uses a manual drain, while automatic and differential-pressure drains are available in the series if you cannot rely on scheduled draining. The 40 um element is the standard grade; specify code W for 5 um where finer particulate removal matters. The round gauge here reads in psi; MPa and bar scales are alternatives. Thread is PT as standard - G (BSPP) and NPT are order options, and the mounting bracket is included. Flow is published as curves, not a single rating, so ask us to confirm sizing against your application before ordering.
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 there is no one number we can quote honestly. Send us your application details and we will confirm the flow figures from the datasheet for this size-400, PT3/8 combination before you order.
The L code marks the low-pressure regulator variant of the GC combination. A separate adjustment-range figure for this variant is not published in the material we hold, so we confirm the exact setting range from the datasheet on request. The unit otherwise keeps the standard three-unit layout - filter, regulator and lubricator - with the round psi gauge and reverse (check) valve fitted.
