The AirTAC GC40010AF2G AirTAC F.R.L. Unit 3/8" G Thread 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 GC40010AF2G is an AirTAC GC-series three-unit F.R.L. combination that conditions compressed air in one assembly: a filter removes water and particulate, a regulator holds downstream pressure steady, and a lubricator adds an oil mist for downstream air tools and cylinders. This size 400 unit is built with a G3/8 (3/8 inch) G-thread port, an automatic drain on the filter bowl, a 40 um standard filter element, and a square pressure gauge scaled in psi. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulator adjustment range is 0.15-0.9 MPa (20-130 psi), and the operating temperature range is -5 to 70 C (non-freezing). The bowls on the 400 size are polycarbonate (PC), and a mounting bracket is included.
This is a genuine AirTAC part. The GC series is available in sizes 200, 300, 400 and 600 with port options from 1/8 to 1 inch, a choice of differential-pressure, automatic or manual drain, a 5 um optional filter element (code W), gauge scales in MPa, psi or bar, and PT, G or NPT threads. Flow is published in the AirTAC catalogue as curves rather than a single rated figure, so contact us and we will confirm the datasheet and flow figures 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 0.15 - 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.

Feeding a CNC machining cell's main air drop, where the filter strips water and swarf-laden condensate from the header supply, the regulator holds a steady tool pressure, and the lubricator mists the air serving pneumatic clamps and tool changers.
Conditioning the air feeding the cylinders and actuators on a carton-forming and sealing conveyor line: clean, regulated and lubricated air keeps the pick-and-place and box-eject strokes working consistently through the shift.
Supplying the service-bay air ring main in a truck or bus workshop, where impact wrenches, tyre chucks and lifting gear all draw from the same line and need filtered, pressure-controlled, oil-misted air to perform reliably.
Choose the GC series when a line needs filtration, regulation and lubrication together as one three-piece F.R.L. combination. Size 400 with a G3/8 port is the mid-large step of the range; match the size and port to the pipe diameter and required flow, stepping up if the circuit demands more air. The automatic drain on this unit keeps the filter bowl emptied without manual attention, which suits unmanned or hard-to-reach installations; manual and differential-pressure drain versions are available if you prefer. The 40 um element is the standard grade for general plant air, with a 5 um element (code W) offered where finer filtration is needed. The fitted square gauge here reads in psi, and MPa or bar scales plus an external round gauge are alternatives. Threads come as PT (standard), G or NPT - this unit is the G-thread variant - and a mounting bracket is included.
Because AirTAC publishes flow as curves rather than a single rated number, we do not quote a rated flow figure here. Ask us to confirm the datasheet and check the sizing of the GC40010AF2G 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 GC series as curves in the catalogue rather than as a single rated figure, so we do not quote a rated flow number. Contact us and we will confirm the datasheet and check the flow curve for the GC400 at G3/8 against your application's air demand before you order.
The A in the code means the filter bowl carries an automatic drain, which expels collected condensate on its own - useful where the unit is mounted in a hard-to-reach spot or on a line that runs unattended. The GC series is also available with a differential-pressure drain (the default) or a manual drain if you would rather control draining yourself; just ask for the equivalent code.
