The AirTAC GC400C10AF2K AirTAC F.R.L. Combination, PT3/8 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 See datasheet ports, a 40 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC400C10AF2K 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 for 3/8 in (PT3/8) compressed-air lines. In this configuration the filter carries the standard 40 um element with an automatic drain, so collected condensate is expelled without manual attention; the regulator is the standard type with a 0.15-0.9 MPa (20-130 psi) adjustment range, an embedded square gauge scaled in psi, and a reverse/check valve fitted; the lubricator delivers oil mist downstream to air tools and cylinders. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). The filter and lubricator bowls on this size 400 unit are polycarbonate (PC), and a mounting bracket is included.
This is a genuine AirTAC part. The GC family is offered in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, in PT (standard), G (BSPP) or NPT thread, with a choice of drain type, filter grade (40 um standard, 5 um optional), gauge style and scale, and reverse/check valve. Flow is published as curves rather than a single rated figure, so ask us and we will confirm the datasheet 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-C1 filter, GR400-C1 regulator and GL400-C1 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.

Supplies filtered, regulated and lubricated air to the clamping cylinders and air vices on a CNC machining cell, with the psi gauge giving the operator a direct setpoint readout at the machine.
Feeds clean, regulated, oil-misted air to the cylinders and air-operated sealers on a carton packing conveyor, where the automatic drain keeps condensate out of the valves during continuous shifts.
Installed at a plant maintenance-shop air drop to condition the supply for impact wrenches, grinders and blow guns, with the reverse/check valve holding the downstream setting if upstream pressure dips.
Start with the port step: this unit is size 400 with a 3/8 in PT port; larger sizes carry larger ports and more flow capacity, so match the size to the air demand of the line. Choose the drain type where a filter is involved: differential-pressure drain (default), automatic drain (as here, code A) for unattended condensate removal, or manual drain. Choose the filter grade: 40 um standard or 5 um (code W) where finer particulate removal is needed. Select the gauge style and scale (square embedded or external round; MPa, psi or bar), whether a reverse/check valve is required, and the thread: PT is the standard, with G (BSPP) and NPT available as order options. A mounting bracket is included on this unit. Because flow is published as curves and not as a single rated number, 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-C1 regulator with a GF400-C1 filter on that branch.
AirTAC publishes flow for this series as curves rather than a single rated figure, so no single rated flow number is stated here. Tell us your line pressure and air demand and we will confirm the datasheet flow figures for the GC400 on request before you order.
Code A in GC400C10AF2K specifies an automatic drain on the filter bowl, so condensate is expelled without operator attention. The alternatives are the differential-pressure drain (the default when no drain code is given) and the manual drain (code M). The choice affects the regulator adjustment range: with automatic or differential-pressure drain the range is 0.15-0.9 MPa (20-130 psi), while with manual drain it is 0.05-0.9 MPa (7-130 psi).
