The AirTAC GC400C15F2GK AirTAC F.R.L. Combination Unit, G1/2 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-unit F.R.L. combination: a separate air filter, a pressure regulator and an oil-mist lubricator, assembled as one set so a compressed-air supply can be cleaned, regulated and lubricated at a single take-off point. This configuration is the size 400 unit with a G1/2 (BSPP) port, the standard 40 um filter element and a differential-pressure drain that bleeds collected water automatically whenever the pressure differential across the element is high enough. The regulator is the standard type with a fitted square gauge scaled in psi, and a reverse/check valve is fitted so downstream pressure is held if the upstream supply is lost. The filter and lubricator bowls on this size are polycarbonate.
This is a genuine AirTAC part from the GC range, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, and options including automatic or manual drains, a 5 um filter element (code W), gauge scales in MPa, psi or bar, and PT, G or NPT threads. We do not publish a single rated-flow figure - flow appears in the catalogue as curves - so ask us to confirm sizing and datasheet figures for your application before ordering.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.

Feeding a machine tool's pneumatic clamps, tool-changer cylinders and air-blast nozzles from one take-off: the filter strips water and swarf-laden particulate, the regulator holds a steady setting at the fixture, and the lubricator mists oil to the actuated components.
A wall-mounted supply point at a spray booth or prep station, where the filter removes water that would fish-eye the finish, the regulator sets a consistent gun pressure, and the lubricator conditions air tools used at the same station.
Supplying the cylinders, grippers and vacuum generators along a packaging conveyor: clean, regulated air keeps sealing and case-packing motions repeatable through the shift, and the lubricator services the air cylinders running continuously on the line.
Start with the port and size: this unit is size 400 with a 1/2 inch port; step up or down through the 200/300/400/600 range to match the pipe size and duty of your line, and let us confirm the flow against your demand before you order. Drain choice matters: the differential-pressure drain fitted here needs no daily attention, while automatic (code A) drains continuously and manual (code M) drains only when operated - the manual-drain version also widens the regulator adjustment range down to 0.05 MPa. The standard element is 40 um; specify code W for 5 um where finer particulate removal matters. The square gauge here reads psi; MPa and bar scales and an external round gauge are alternatives. Thread is G (BSPP) on this model, with PT as the catalogue standard and NPT available to order. A mounting bracket is included.
Because flow is published as curves rather than a single rating, send us your application details and we will confirm the right size before you commit.
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, not as a single rated number, so we do not quote a figure here. Tell us your line pressure and the air demand of your equipment, and we will confirm the sizing against the datasheet curves on request before you order.
The K in the model code means a reverse/check valve is fitted, so air already downstream of the set is held if the upstream supply drops - useful where a cylinder or clamp must not release on a supply loss. The differential-pressure drain on the filter bowl ejects collected condensate automatically when the pressure differential across the element rises, with no manual draining needed in normal service.
