The AirTAC GC400C15C2WG AirTAC F.R.L. Combination, G1/2, 5 um 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 GC400C15C2WG is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one supply package. This configuration is built around a G1/2 (BSPP) port in the size-400 frame, with the 5 um filter element (code W) for finer water-and-particulate removal than the 40 um standard element. The filter bowl uses a differential-pressure drain, the regulator is the standard type with a 0.15-0.9 MPa (20-130 psi) adjustment range, and an external round gauge with a psi scale is fitted for setpoint reading. Mounting brackets are included.
This is a genuine AirTAC part. The GC series is offered in sizes 200, 300, 400 and 600 with matching port sizes, a choice of 40 um or 5 um filtration, differential-pressure, automatic or manual drains, gauge style and scale, and PT, G or NPT threads as order options. Flow is published as curves rather than a single rated figure, so we confirm the datasheet 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.

Feeds 1/2 in tool-air drops on an assembly line, cleaning and regulating the supply while the lubricator carries a fine oil mist to keep air impact wrenches and nutrunners running through a full shift.
Conditions the air feeding conveyor stopper and clamp cylinders on a carton packaging line: 5 um filtration protects valve spools, the regulator holds the actuator pressure, and the lubricator services the cylinder seals.
Mounted at the cell inlet of a CNC machining centre, it removes water and fine particulate before the machine's air valves, keeps clamping circuit pressure steady on the psi gauge, and mists oil for pneumatic chip-blowing and tool-change circuits.
Start with the port and size: this unit steps up to 1/2 in on the size-400 frame, so check it against the pipe size and the air demand of the circuit it feeds - flow is published as curves, not a single rating, so ask us to confirm sizing before ordering. Drain type is a real choice: differential-pressure (as coded here) drains automatically as flow passes, while automatic and manual variants are available in the series. Filtration is 5 um with this code versus the 40 um standard element - choose 5 um where downstream equipment needs finer air. The fitted gauge here is the external round type with a psi scale; square embedded gauges and MPa or bar scales are the other options. Thread is G (BSPP) on this code, with PT standard and NPT available to order. Brackets are included; a reverse/check valve is not fitted but is available in the family.
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 performance curves rather than a single rated figure, so there is no one rated flow number we can honestly quote. Send us your line pressure and air demand and we will confirm the sizing against the datasheet curves on request before you order.
The W in the code GC400C15C2WG selects the 5 um element, which removes finer particulate than the 40 um standard element. It is the right choice where downstream valves, cylinders or instruments are sensitive to fine contamination; the 40 um element remains the series default if coarser pre-filtration is all that is needed.
