The AirTAC GC40010ALF2W AirTAC F.R.L. Combination, 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 automatic drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC40010ALF2W is an AirTAC GC-series three-unit F.R.L. combination: a separate filter, regulator and lubricator assembled as one set, so compressed air is cleaned of water and particulate, held at a set working pressure, and carrying a fine oil mist to downstream equipment. This configuration is the 400 size with a 3/8 in PT port, fitted with the 5 um filter element (code W) for finer filtration than the standard 40 um, an automatic drain that expels collected condensate from the filter bowl without manual attention, and the low-pressure regulator type for circuits that operate below standard line pressures. The embedded square gauge reads in psi, and a mounting bracket is included.
This is a genuine AirTAC part. The GC family is offered in the 200, 300, 400 and 600 sizes with ports from 1/8 in to 1 in, and with choices of drain type, filter grade, gauge scale and thread (PT standard; G and NPT as order options). Flow is published as curves rather than a single rated figure, 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.

Feeding cleaned, regulated and lubricated air to the tool-changer, clamps and pneumatic actuators on a machining centre, where the 5 um element protects fine spools from particulate and the automatic drain keeps condensate out of the circuit.
Supplying the cylinders and diverters on a carton packing or palletising line, where the low-pressure regulator holds a gentle working pressure for delicate grip motions and the lubricator keeps cylinder seals running smoothly through long shifts.
Conditioning the air ahead of spray guns in a finishing booth: the 5 um filter removes water and dirt that would ruin a finish, the regulator sets the gun supply pressure, and the oil mist keeps downstream valves and hoses in good order.
Step up or down through the 200 / 300 / 400 / 600 sizes to match the port and the flow your line needs; this 400 size carries a 3/8 in PT port. The 5 um element (W) suits air tools, valves and instruments that need cleaner air than the standard 40 um element provides. The low-pressure regulator type is the right choice where the circuit works below standard line pressures - confirm the exact adjustment range with us before ordering, as it is not published in the standard table. The automatic drain keeps the bowl clear without daily attention; manual and differential-pressure drains are available on other codes if you prefer a different drainage style.
Thread is PT as standard, with G (BSPP) and NPT available as order options - pick the one that matches your existing pipework. The square gauge is fitted here reading psi; MPa and bar scales and an external round gauge are alternatives. Flow 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 this series as curves rather than a single rated figure, so we do not quote a rated flow number. Send us your application details and we will confirm the flow and sizing from the datasheet on request before you order.
The A in the code selects the automatic drain, which expels collected condensate from the filter bowl on its own instead of relying on manual draining or a differential-pressure trigger. The W selects the 5 um filter element instead of the standard 40 um, giving finer protection for downstream tools and valves.
