The AirTAC GC400-10 AirTAC Three-Unit F.R.L. Combo, PT3/8, 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 PT3/8" ports, a 5 µm element, a manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi).
The AirTAC GC400-10 is a three-piece F.R.L. combination that filters, regulates and lubricates compressed air in one assembly: a separate filter, a regulator and an oil-mist lubricator. This 400-size unit is fitted with a 3/8 inch PT port, a 5 um filter element (the finer of the two catalogue grades), a manual drain on the bowl, and a reverse/check valve. The regulator is the standard type with an adjustment range of 0.05-0.9 MPa (7-130 psi), and a round external gauge with a psi scale is fitted so the set pressure can be read directly. The polycarbonate bowl is drained by hand, which suits installations where an operator is already present.
This is a genuine AirTAC part from the GC series, which spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, a choice of differential-pressure, automatic or manual draining, 40 um or 5 um filtration, gauge style and scale options, and PT, G or NPT threads. Flow figures for this series are published as curves rather than a single rating, so ask us to confirm the 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 0.05 - 0.9 MPa (7 - 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: GF400-10 filter, GR400-10 regulator and GL400-10 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 clean, regulated and lubricated air to the tool-changer and clamping cylinders on a CNC machining centre, with the 5 um element protecting precision valves from particulate and the psi gauge letting setters verify clamp pressure at a glance.
Installed as the point-of-use treatment unit on a bottling conveyor's pneumatic actuator drop, conditioning the air that strokes the bottle-grip and stopper cylinders and keeping the line's air tools oiled through the lubricator.
Mounted at an automotive assembly bench to supply impact wrenches and nutrunners, where the regulator sets the tool torque band, the lubricator mists oil into the tool air stream, and the manual drain is emptied during shift changeover.
Step up or down through the GC sizes (200, 300, 400, 600) so the port and body match the flow your line needs; this 400 size carries a 3/8 inch PT port. Choose the drain type deliberately: manual draining (as fitted here) means an operator opens the bowl drain periodically, while automatic and differential-pressure drains handle condensate without that attention. The 5 um element fitted here is the finer option against the 40 um standard - pick it when downstream valves and cylinders need cleaner air. Gauge style (embedded square or external round) and scale (MPa, psi or bar) are decodable choices, as are the thread family (PT standard, G or NPT to order) and the reverse/check valve, which is fitted on this unit.
Because flow for the GC series is published as curves and not as a single rated figure, we cannot quote one number here - send us your application details and we will confirm the 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 GR400-10 regulator with a GF400-10 filter on that branch.
AirTAC publishes flow for the GC series as performance curves rather than a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the relevant datasheet figures for this 400-size, 3/8 inch unit before you order.
The bowl on the filter section collects water and is emptied by hand: an operator opens the drain periodically instead of relying on an automatic or differential-pressure drain. It is a straightforward choice for attended installations, and automatic-drain versions of the same unit are available if unattended draining is preferred.
