The AirTAC GC400-10 AirTAC F.R.L. Combination, PT3/8, Low-Pressure 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 40 µm element, a automatic drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC400-10 is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one set. This configuration is size 400 with PT3/8 ports, fitted with an automatic drain on the filter bowl, a 40 um standard filter element, and a low-pressure type regulator. It conditions compressed air in one pass: water and particulate are drained off, downstream pressure is held at the set point, and a fine oil mist is carried into the air line to lubricate downstream pneumatic components. A round external gauge on a psi scale is fitted so the regulated pressure can be read directly.
This is a genuine AirTAC part. The GC series is available in sizes 200, 300, 400 and 600, with port sizes from 1/8 to 1 inch, PT as the standard thread and G or NPT as order options, plus choices of drain type, 40 um or 5 um filtration, gauge style and scale. Flow figures for this series are published as curves rather than a single rating, 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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.

Installed ahead of a pneumatic press or clamping station, the set removes condensed water and swarf, holds a stable regulated supply, and meters oil mist to extend cylinder and valve life.
Mounted at the line drop feeding conveyor diverters, case packers and filling heads, it keeps the air dry, filtered, lubricated and regulated so actuators cycle consistently through the shift.
Fitted on the air inlet of CNC machines and machining centres, it conditions the supply to tool changers, clamps and air bearings, with the psi gauge giving operators a direct pressure readout.
The GC400-10 sits at the size 400 step of the GC range with PT3/8 ports; step up or down (200/300/400/600) to match the port and flow path of the machine it feeds. Drain type is a real choice: automatic drain (fitted here) empties the bowl without operator attention, while manual and differential-pressure drains suit attended or duty-based setups. The filter element is 40 um standard; specify the W code for 5 um where finer filtration is needed. This unit is the low-pressure type, so confirm your working pressure band before ordering.
Gauge style and scale are decodable options: an embedded square gauge is standard, an external round gauge is optional, and scales are MPa, psi or bar (this unit carries a round psi gauge). Thread is PT as standard with G (BSPP) and NPT available to order. Flow for the 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 GR400-10 regulator with a GF400-10 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. Tell us your application and line conditions and we will confirm the flow and sizing from the datasheet on request before you order.
The L in the code GC40010ALC2 marks the low-pressure regulator type, intended for circuits working below the standard pressure band; the exact adjustment range for this type is not published, so confirm it with us. The A marks an automatic drain, which expels collected condensate from the filter bowl by itself instead of waiting for a manual drain.
