The AirTAC GC400C15AF2K 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, assembled as one air-preparation set. This GC400C15AF2K is the size 400 unit with a 1/2 in PT port. The filter element is the standard 40 um grade and carries an automatic drain, so collected condensate is discharged without manual attention. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), an embedded square gauge graduated in psi, and a reverse (check) valve fitted. A mounting bracket is included, and the max inlet pressure is 1.0 MPa (145 psi) with an operating temperature range of -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GC family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and with options such as manual or differential-pressure drains, a 5 um filter element (code W), alternative gauge scales in MPa or bar, G (BSPP) or NPT threads, and a low-pressure regulator type. Flow is published in the AirTAC catalogue as curves rather than a single rated figure, so we confirm the datasheet and sizing figures 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.

Feeding a cleaned, regulated and lubricated air supply to the impact wrenches, clamps and pneumatic tooling along a vehicle assembly line, with the automatic drain handling condensate from the shop-air main.
Conditioning the air feeding conveyor diverters, case packers and palletiser gripper cylinders, where the regulator holds a stable setpoint for repeatable stroke behaviour and the lubricator mists the actuator seals.
Preparing the shop air entering a CNC machining centre's pneumatic circuit - tool changer, clamping and chip-clearing actuators - with 40 um particulate removal, a regulated setpoint read on the psi gauge and check-valve protection against downstream backflow.
Start with the port and size step: the GC series steps through sizes 200, 300, 400 and 600, and this unit is size 400 with a 1/2 in PT port - pick the size whose flow curve covers your worst-case air demand, since larger sizes give larger ports and more flow. Then set the drain: automatic (this unit) discharges condensate by itself, manual drain needs operator attention, and the differential-pressure drain is the default choice. Filter grade is 40 um standard or 5 um with code W if downstream equipment needs finer filtration. The gauge scale here is psi; MPa and bar scales are also available, and an external round gauge is an option alongside the standard embedded square gauge. Thread is PT as standard, with G (BSPP) and NPT offered as orderable options, and a bracket is included.
One honest note before you order: AirTAC publishes filter-regulator-lubricator flow as curves, not as a single rated number, so we do not quote a rated flow figure here. Ask us to confirm the flow curve and datasheet against your application before you commit to a size.
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 in the catalogue, not as a single rated figure, so we do not state a rated flow number here. Tell us your line pressure, set pressure and worst-case air consumption, and we will confirm the flow curve and datasheet figures for this size 400, 1/2 in unit against your application before you order.
The A in the code GC400C15AF2K means the filter bowl carries an automatic drain, which discharges collected condensate without anyone opening the bowl - useful on lines that run unattended or in humid environments. The alternatives are a manual drain, where an operator drains the bowl periodically, and the differential-pressure drain (the default when no drain letter appears in the code). All three are catalogue options across the GC range.
