The AirTAC GC400C15AC2WG 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 AirTAC GC series is a three-piece F.R.L. combination: a separate air filter, pressure regulator and lubricator assembled to deliver cleaned, regulated and oil-misted compressed air from one supply point. This GC400C15AC2WG is set up for 1/2 inch lines with G (BSPP) threads, carries the W code 5 um filter element instead of the standard 40 um, and has the A code automatic drain. The standard-type regulator adjusts from 0.15 to 0.9 MPa (20-130 psi), a round gauge with a psi scale is fitted, and a mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi), the operating temperature range is -5 to 70 C (non-freezing), and the filter bowl on this size is polycarbonate.
This is a genuine AirTAC part. The GC family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, and can be ordered with manual or differential-pressure drains, a 40 um or 5 um element, embedded square or external round gauges in MPa, psi or bar scales, a reverse/check valve, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

A 1/2 inch drop feeding a pneumatic press gets one conditioning point: the filter strips water and particulate before the air cylinders and control valves, the regulator holds a steady working pressure, and the lubricator meters oil mist into the supply.
Carton formers and case sealers run on air cylinders and valves that suffer from condensate and scale. This F.R.L. set on the line's 1/2 inch supply cleans the air, pins the pressure for consistent cylinder action and feeds oil mist to the actuators.
Bench drops serving impact wrenches, ratchets and other air tools at an assembly station use this unit to remove water and dirt, hold the tool pressure set on the psi gauge and deliver lubricated air to the tools.
Size and port step up together: this size 400 unit carries a 1/2 inch G (BSPP) port, one step above the 3/8 inch of size 300, so pick the size whose flow curve covers your air demand. The remaining choices are all in the code: A gives the automatic drain instead of manual or differential-pressure, W gives the 5 um element where downstream equipment needs finer filtration than the standard 40 um, and C2 fits the round gauge with a psi scale in place of the embedded square gauge. Thread is G here; PT is the standard and NPT is an order option.
Because flow is published as curves rather than a single rating, send us your line pressure and expected air demand and we will confirm sizing against the datasheet 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 we do not quote a number here. Send us your line pressure and expected air demand and we will confirm the flow curve and the datasheet figures for the GC400C15AC2WG on request.
W is the filter-grade code: this unit carries the 5 um element instead of the standard 40 um. Choose 5 um where the downstream valves and cylinders need finer particulate removal; the 40 um element remains the default on other GC models.
