The AirTAC GC400C10ALC2K AirTAC F.R.L. Unit PT3/8 Low-Pressure Type 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 GC400C10ALC2K is an AirTAC GC three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator supplied as one set. This size 400 unit is threaded PT3/8 (3/8 in). The filter bowl drains automatically, so collected condensate is expelled without manual intervention, and the standard 40 um element removes water and particulate from the compressed air. The regulator is the low-pressure type, and a round external gauge with a psi scale is fitted so the set pressure can be read directly. A reverse/check valve (code K) is fitted, and the mounting bracket is included.
This is a genuine AirTAC part. The GC series is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and with manual, automatic or differential-pressure drains, an optional 5 um filter element (code W), gauge scales of MPa, psi or bar, and G (BSPP) or NPT threads as order options. Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rated figure, so ask us to confirm sizing and datasheet figures for your application.

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.

Feeds filtered, regulated and lubricated air to the pneumatic drivers and clamps at a car-body trim station, with the automatic drain clearing condensate through shift changes.
Supplies the gripper and clamp actuators on a palletizing cell with clean, pressure-regulated, oil-misted air so cylinders and seals run consistently across long production runs.
Conditions the air driving case-erector and sealing cylinders on a packaging conveyor, where the 40 um element protects directional valves and the lubricator keeps cylinder seals working.
Size 400 with a 3/8 in PT port sits mid-range in the GC series; step up to 600 or down to 300 or 200 according to the flow your line needs - ask us to confirm sizing against the published curves before ordering. The filter bowl on this code drains automatically; manual (M) and differential-pressure (blank) drains are the alternatives on other codes. The 40 um element is standard; specify W for the 5 um grade where finer particulate removal is required. This code carries the low-pressure regulator type - the exact adjustment range is not published, so confirm it with us if your set pressure is critical. The fitted round gauge reads in psi; the embedded square gauge and MPa or bar scales are the other catalogue choices. Thread is PT as standard, with G (BSPP) and NPT available as order options, and the bracket is included.
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 a number here. Tell us your line's flow and pressure requirements and we will confirm sizing against the datasheet on request before you order.
On this code the filter bowl expels collected condensate automatically, so no manual draining is needed. The GC series is also catalogued with a manual drain (code M) or the differential-pressure drain (blank) if a different arrangement suits your installation.
