The AirTAC GC400C10ALF2GK AirTAC 3/8" F.R.L. Combination Unit 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 GC400C10ALF2GK is an AirTAC GC-series three-unit F.R.L. combination: a separate filter, regulator and lubricator assembled as one air-preparation set. This configuration is the size 400 unit with a 3/8 inch port in G (BSPP) thread, fitted with an automatic drain on the filter bowl, the standard 40 um filter element, a low-pressure type regulator, an embedded square gauge scaled in psi, a reverse/check valve, and the mounting bracket. In use it conditions a compressed-air line in one station: water and particulate are drained off automatically, downstream pressure is held at the set point, and oil mist is delivered to the air tools and actuators that follow.
This is a genuine AirTAC part. The GC family is offered in sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, and with choices of thread (PT standard; G and NPT as order options), drain type, filter grade (40 um standard, 5 um with code W), gauge scale and reverse valve. 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. 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.

Feeding a production hall's 3/8 inch branch line, the combination filters condensate out with automatic draining, holds a stable low-pressure supply to the drop, and lubricates the air tools hung along it.
On a carton-forming and conveying line, the set prepares the air for pneumatic cylinders and grippers: clean, drained, pressure-regulated and oil-misted so the actuators run consistently through the shift.
Supplying clamps and vise cylinders on a CNC cell, the unit removes water and chips-laden particulate at 40 um, regulates the clamping pressure at a low set point, and mists the air to keep the mechanism lubricated.
Size and port step up with required flow: this unit is size 400 with a 3/8 inch G-thread port; if your line needs more or less air, the neighbouring 300 and 600 sizes step the port and capacity accordingly. The automatic drain on this model handles condensate without daily manual attention - choose the manual-drain variant where you prefer operator-controlled draining. The 40 um element is the standard grade; specify code W for the 5 um element where finer particulate removal matters. The square gauge on this unit reads in psi; MPa and bar scales are available, and an external round gauge is optional. PT is the standard thread, with G and NPT as orderable options, and the bracket is included. Note that the regulator on this unit is the low-pressure type - its exact adjustment range is not published, so confirm it with us against your set point. Because flow is published as curves rather than a single rating, 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 the GC series as curves rather than a single rated figure, so we do not quote one number. Tell us your line pressure and the air demand of your equipment and we will confirm the sizing from the datasheet on request.
In the code GC400C10ALF2GK, the A sets the automatic drain (the alternatives are manual, or the differential-pressure default), and F2 sets the embedded square gauge with a psi scale - MPa and bar scales are also available, and an external round gauge is optional. The L marks the low-pressure regulator type and K the fitted reverse/check valve.
