The AirTAC GC400C15MLC2 AirTAC F.R.L. Combination 1/2 in Low-Press 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 GC400C15MLC2 is a genuine AirTAC GC-series three-unit F.R.L. combination: a filter, a regulator and a lubricator supplied as separate units that together remove water and particulate, regulate pressure and add oil-mist lubrication to compressed air. This size 400 configuration is threaded PT1/2, carries a 40 um filter element with a manual drain, and is built as the low-pressure regulator type. A round gauge scaled in psi is fitted, the mounting bracket is included, the bowls are metal, and maximum inlet pressure is 1.0 MPa (145 psi). Operating temperature is -5 to 70 C (non-freezing).
Across the GC range AirTAC offers sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, a choice of differential-pressure, automatic or manual drains, 40 um standard or 5 um (W) filtration, embedded square or external round gauges with MPa, psi or bar scales, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so ask us to confirm the 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.

Filtered, regulated and lubricated air at the paint-line drop keeps spray guns fed with clean, moisture-reduced air at the set pressure, with the manual drain emptied during shift changeovers.
On a carton-forming and sealing line, the combination conditions the air feeding pick-and-place cylinders and actuators, holding a stable low set pressure while the lubricator mists oil to the valves and cylinders.
At the inlet of a machining centre's pneumatic circuit, the unit removes water and particles, regulates supply to the tool-change clamps and oils the air cylinders and valve components.
Choose the size and port step (200 through 600, 1/8 to 1 inch) against the air demand of the line - larger sizes suit higher demand. Pick the drain: manual (as here) is emptied by hand on a schedule, automatic drains on its own, and differential-pressure drains as the element loads up. Filter grade is 40 um standard or 5 um with the W code. Gauge style is embedded square or external round, scaled in MPa, psi or bar (this unit: round, psi). Thread is PT as standard, with G and NPT as orderable options. The low-pressure (L) regulator type suits circuits set below standard line pressure; its exact adjustment range is not published, so confirm it with us. Because flow is published as curves rather than one rated number, send us your application 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 quote one number. Tell us your line pressure, set pressure and air demand and we will confirm the datasheet curve figures for this exact configuration on request.
The L marks the low-pressure regulator type, intended for circuits set below standard line pressure; its exact adjustment range is not published, so confirm it with us before ordering. The M marks a manual drain: open it periodically to empty accumulated water from the filter bowl rather than relying on an automatic or differential-pressure drain.
