The AirTAC GC400C15ALC2 AirTAC F.R.L. Combination, PT1/2 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-piece F.R.L. combination: a separate air filter, a pressure regulator and an oil-mist lubricator, giving downstream equipment clean, regulated, lubricated compressed air from one assembly. This GC400C15ALC2 is the size 400 unit with 1/2 in PT ports, an automatic drain on the filter bowl, the standard 40 um filter element and a polycarbonate bowl, a low-pressure type regulator, and an external round gauge reading in psi. The mounting bracket is included, no reverse/check valve is fitted, maximum inlet pressure is 1.0 MPa (145 psi), and the unit is rated for -5 to 70 C in non-freezing conditions.
This is a genuine AirTAC part. The GC family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and can be ordered with manual or differential-pressure draining, a 5 um element (code W), square or round gauges in MPa, psi or bar scales, and G (BSPP) or NPT threads in place of the PT standard. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and check sizing 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 clean, regulated, lubricated air to clamps, tool changers and actuation on a machining centre. The filter strips water and particulate before they reach spool valves, the regulator holds the circuit setpoint, and the lubricator carries oil mist to the cylinders.
Point-of-use preparation for carton-forming, filling and sealing heads on a packaging conveyor. The automatic drain keeps condensate out of the bowl without operator attention, and the round psi gauge lets line staff verify the regulated pressure at a glance.
Bench-mounted FRL stations serving impact wrenches, air ratchets and pneumatic presses across an assembly hall. The lubricator mists oil into the tool air supply, the 40 um element protects the regulators and valves downstream, and the bracket gives a fixed mounting point.
Every meaningful choice on this family is decodable from the code. Size 400 with 1/2 in PT ports suits lines running larger cylinders and valves; step down to 300 or up to 600 if your air demand differs. The A in this code specifies an automatic drain, which handles condensate without attention - manual (M) or differential-pressure (blank) draining can be ordered instead. The standard 40 um element covers most actuation duty; the W code gives a 5 um element where finer filtration is needed. The regulator here is the low-pressure type, and its exact adjustment range is not published in the catalogue, so confirm it with us if your setpoint is critical. The gauge on this unit is the external round type reading in psi; MPa and bar scales are alternatives. PT is the standard thread, with G and NPT as order options, and the mounting bracket is included.
Flow for the GC series is published as curves, not a single rating, so we cannot quote one number here. Send us your application details and we will confirm the datasheet figures and check the sizing against your demand 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 there is no one number we can honestly quote. Tell us your application and air demand, and we will confirm the datasheet flow curves for this size 400, 1/2 in unit and check the sizing with you before you order.
The A in the code specifies an automatic drain, which expels collected condensate from the filter bowl without manual attention - useful where the unit is mounted in an awkward or rarely visited position. The same size 400 unit can be ordered with a manual drain (code M) or the default differential-pressure drain (no code) if you prefer drain behaviour tied to pressure drop.
