The AirTAC GC400C15AC2 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 GC series is AirTAC's three-piece F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one conditioning set. This GC400C15AC2 is built for a PT1/2 (1/2 in) PT-threaded port and carries the 40 um standard filter element with an automatic drain, so collected water is expelled from the polycarbonate filter bowl without manual attention. The standard regulator adjusts outlet pressure across 0.15-0.9 MPa (20-130 psi) and a round gauge reading in psi is fitted; a mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GC range spans sizes 200, 300, 400 and 600, with manual or differential-pressure drains, a 5 um filter element (code W), gauge scales in MPa, psi or bar, and G or NPT threads as order options. Flow for this series is published as curves rather than a single 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.

Conditioning the compressed air feeding clamp and weld-gun actuation cylinders on an automotive body line: water and particles removed, pressure held steady for consistent clamping force, and oil mist carried to the cylinder seals.
Supplying treated air to the stopper and gate cylinders that index bottles along a filling line, where steady regulated pressure keeps indexing repeatable and lubrication helps the actuators run cleanly.
A conditioned drop at a plant maintenance bay feeding impact wrenches, air ratchets and blow guns: filtered and regulated supply with oil mist for the tools, at a 1/2 in PT connection.
Choose the size by port and flow: this size 400 unit takes a 1/2 in PT port, and stepping up or down a size changes both. Drain type is a real choice: automatic (this model) empties the filter bowl on its own, manual needs a periodic press, and differential-pressure drains only as the element loads up. Filter grade is 40 um standard or 5 um with code W if finer filtration is needed. Gauge scale (MPa, psi or bar) and thread (PT standard, G or NPT to order) are set at ordering. Flow for the GC series is published as curves, not a single rating, so ask us to confirm sizing against your application 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 there is no one number we can quote honestly. Send us your inlet pressure, downstream demand and allowable pressure drop, and we will confirm the datasheet curve and sizing for your application on request.
This model has an automatic drain, so condensate collected in the filter bowl is expelled without anyone attending it, which suits lines that run unattended. Manual and differential-pressure drains are order options across the GC range if you prefer a different arrangement.
