The AirTAC GC400-10 AirTAC F.R.L. Combination, PT3/8, 5 um Filter 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: a separate air filter, pressure regulator and oil-mist lubricator assembled as one air-preparation set. This size 400 unit carries a PT3/8 (3/8 in) PT thread, and the filter element in this configuration is the fine 5 um grade (W) with a manual drain, so water and particulate down to 5 um are removed and the bowl is emptied by hand rather than automatically. The regulator is the standard type with a fitted round gauge scaled in psi, and the lubricator meters oil mist into the downstream air. Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing). The bowls on the 400 size are polycarbonate (PC); only the 600 size uses aluminium alloy.
This is a genuine AirTAC part. The GC family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drains, 40 um standard or 5 um (W) filter elements, gauge scale options in MPa, psi or bar, and PT, G or NPT threads. Flow figures for this series are published as curves rather than a single rated number, so ask us to confirm the datasheet and sizing 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 0.05 - 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 spray guns and air-driven agitators on a paint line, where the 5 um element protects finish quality from water and fine particulate, the regulator holds a steady gun pressure, and the lubricator conditions downstream air tools.
Sits at the drop of a packaging conveyor, supplying filtered, regulated and lubricated air to the cylinders and grippers that clamp, fold and seal cartons through each shift.
Prepares the air supply for a bench-mounted pneumatic press and its clamping fixtures, keeping the regulator gauge in view at the cell so operators can verify line pressure in psi before a cycle.
Start with the port and size: the GC400 step covers 3/8 in ports, and the right size is the one whose flow curve covers your downstream demand with margin - we can check that against the datasheet before you order. This unit is specified with a manual drain, which suits positions where someone is already at the machine and can bleed the bowl on a routine; choose automatic or differential-pressure drain codes if the bowl cannot be attended regularly. The 5 um element here is the finer option; the standard grade is 40 um if your application does not need fine filtration. The round gauge fitted to this code is scaled in psi; square embedded gauges and MPa or bar scales are also available. Thread is PT as standard - G (BSPP) and NPT are order options, specified as a code, not a delivery promise. Flow for the G series is published as curves, not a single rating, so please 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 GR400-10 regulator with a GF400-10 filter on that branch.
AirTAC publishes flow for the G series as curves, not as a single rated figure, so there is no one rated flow number we can quote for the GC400-10. Tell us your application and operating pressure and we will confirm the flow figures from the datasheet on request before you order.
The code GC400-10MC2W specifies M for a manual drain - the bowl is emptied by hand, which suits attended positions - and W for the finer 5 um filter element instead of the 40 um standard grade. If you need automatic drainage or the coarser element, those are separate order codes in the same GC400 family.
