The AirTAC GC400-10-G AirTAC F.R.L. Combination, G3/8 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 AirTAC GC400-10-G is a three-piece F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one unit, giving a G3/8 (3/8 in) supply line complete treatment in a single mounting. The filter element is the standard 40 um grade and the bowl has an automatic drain, so collected water is expelled without manual attention. The standard regulator adjusts over 0.15-0.9 MPa (20-130 psi) and carries a fitted square gauge reading in psi, while the reverse/check valve holds downstream settings if the upstream supply is interrupted. The bowls are polycarbonate on this size and a mounting bracket is included.
This is a genuine AirTAC part from the GC series, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in. Across the range you can order the 5 um (W) filter grade, manual or differential-pressure drains, gauge scales in MPa, psi or bar, and PT, G or NPT threads. We confirm flow and other datasheet figures on request, as flow is published as curves rather than a single rating.

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: GF400-10 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 at the drop feeding pneumatic impact wrenches and nutrunners on an assembly line: the filter removes water and swarf, the regulator holds a steady tool pressure and the lubricator mists oil into the tool air supply.
Mounted on the supply to cylinder-driven diverters and pushers on a bottling or carton packaging conveyor, where the automatic drain copes with condensate from a long compressed-air run and the check valve holds the set pressure during supply dips.
Fitted at a plant maintenance workshop's wall-mounted air station, giving technicians one conditioned outlet for air tools, blow guns and small clamping fixtures, with the psi gauge making regulator set-points easy to read and repeat.
Start with the port and size step: this unit is the 400 size with a G3/8 thread; larger sizes carry larger ports and more flow capacity, so match the step to the demand of the line it feeds. Choose the drain to suit access: automatic (as here) for unattended duty, manual where you prefer controlled draining, or the differential-pressure default. Pick the filter grade - 40 um standard or 5 um (code W) for finer protection - and the gauge scale (MPa, psi or bar). Thread is PT as standard, with G (BSPP) and NPT as order options; a bracket is included.
One honest note on sizing: AirTAC publishes flow as curves, not a single rated figure, so please ask us to confirm flow 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 this series as curves rather than a single rated figure, so there is no one l/min or SCFM number we can quote. Send us your line pressure and air demand and we will confirm the sizing from the datasheet curves on request before you order.
The automatic drain on this GC400 expels collected condensate without operator attention, which suits unattended or hard-to-reach installations. The same series can be ordered with a manual drain for controlled draining, or with the differential-pressure drain as the default; the regulation range differs by drain type, with automatic and differential-pressure types adjusting from 0.15-0.9 MPa (20-130 psi).
