The AirTAC GC400-10 AirTAC F.R.L. Combination, 3/8 in PT 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 GC400-10 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. This configuration is size 400 with a 3/8 in PT port. The filter carries the standard 40 um element with an automatic drain, so collected condensate is discharged without manual attention. The regulator is the standard type with a 0.15-0.9 MPa (20-130 psi) adjustment range, a round gauge reading in psi, and a reverse/check valve fitted. PC (polycarbonate) bowls are used at this size, and a mounting bracket is included.
This is a genuine AirTAC part. The GC family is available in sizes 200, 300, 400 and 600, with 1/8 in to 1 in ports, PT (standard), G or NPT threads, differential-pressure, automatic or manual drains, 40 um or 5 um (W) filter grades, and gauge scale options. Flow is published as curves rather than a single rated figure, so ask us to 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: GF400-10 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.

Feeds cleaned, regulated and lubricated air to the tool-changer and clamping circuits of a CNC machining centre, with the automatic drain handling condensate between shifts.
Conditions the air feeding pneumatic cylinders and grippers on a carton-forming and sealing conveyor, keeping seals lubricated and pressure steady through the cycle.
Installed at the wall drop feeding a row of assembly-station air tools, giving each bench its own filtration, pressure setting and oil-mist lubrication point.
Start with the port step: this unit is size 400 with a 3/8 in PT port, and the GC family steps through 200/300/400/600 with ports from 1/8 in to 1 in, so pick the size whose flow curve covers your demand. Choose the drain to suit access: automatic (this unit) for unattended condensate discharge, manual for supervised draining, or differential-pressure as the default. Filter grade is 40 um standard on this unit; specify 5 um (code W) where finer particulate removal is needed. The gauge here is a round external gauge reading in psi; embedded square gauges and MPa or bar scales are the other options. Thread is PT as standard, with G (BSPP) and NPT available as order options.
Flow is published as curves, not a single rating, so please 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 GR400-10 regulator with a GF400-10 filter on that branch.
AirTAC publishes flow for this family as curves rather than a single rated figure, so we do not quote a number. Tell us your application and we will confirm the flow and datasheet figures for the GC400-10 on request before you order.
The A in the code GC40010AC2K selects the automatic drain, which discharges collected condensate from the filter bowl without manual attention. The GC family is also available with manual or differential-pressure drains, so you can order the drain type that suits how the unit is accessed.
