The AirTAC GC400C15AC2WGK AirTAC F.R.L. Combination 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 GC400C15AC2WGK is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and lubricator built as one conditioning stack. This size 400 unit is configured for a G1/2 (BSPP) port, 5 um filtration (code W, against the 40 um standard), an automatic drain, a round external gauge reading in psi, a reverse/check valve (code K), and the standard regulator with a 0.15-0.9 MPa (20-130 psi) adjustment range. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. The filter carries a polycarbonate (PC) bowl at this size; only size 600 uses aluminium alloy.
This is a genuine AirTAC part. The GC family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, and options across drain type, 5 um or 40 um filtration, embedded square or external round gauges scaled in MPa, psi or bar, a reverse/check valve, and G or NPT thread in place of the PT standard. Flow is published as curves rather than a single rated figure, so we confirm datasheet figures 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.

On a car-body assembly line, this F.R.L. conditions the air feeding pneumatic nutrunners, impact wrenches and clamping fixtures: the filter strips water and particulate, the regulator holds the set pressure at the tool, and the lubricator carries an oil mist into the tool air.
A packaging plant's case erectors and carton sealers run on cylinder air that must stay dry, steady and lubricated through a full shift; this unit filters, regulates and lubricates that supply at one point ahead of the machine's valve manifold.
Spinning frames and loom pneumatics in a textile mill draw compressed air around the clock; this three-unit set gives each machine group filtered, pressure-regulated, oil-misted air so cylinders and air jets keep working in a humid mill environment.
Choose the size step (200/300/400/600) against the port and the flow your line needs - here size 400 with a G1/2 port sits mid-range. Drain type is a real choice: automatic (this unit) drains without attention, manual suits supervised points, and the differential-pressure default needs a pressure drop to work; note the regulator range differs by drain (0.15-0.9 MPa with automatic or differential drain, 0.05-0.9 MPa with manual). Filter grade is 40 um standard or 5 um (W, this unit) where finer protection is wanted. The gauge can be the embedded square type or an external round gauge, scaled MPa, psi or bar - this unit carries a round psi gauge. Thread is PT as standard, with G (BSPP) and NPT as order options, and a mounting bracket is included. Because flow is published as curves rather than a single rating, ask us to confirm sizing against your application before ordering.
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 this family as curves, not as a single rated figure, so there is no one l/min or SCFM number we can quote. Tell us your port size and application and we will confirm the flow figures from the datasheet on request before you order.
The W in the code selects the 5 um element; the family standard is 40 um. Choose 5 um where downstream valves, cylinders or instruments need finer protection, and 40 um for general duty. Both grades are catalogue options across the GC range, and the drain can likewise be ordered automatic, manual or differential-pressure.
