The AirTAC GC400C15ALF2GK AirTAC F.R.L. Unit, G1/2, Low-Pressure 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 GC400C15ALF2GK is a three-piece AirTAC F.R.L. combination that filters, regulates and lubricates compressed air in one assembled set: a separate filter with an automatic drain, a low-pressure regulator with an embedded square gauge scaled in psi, and an oil-mist lubricator. This size 400 unit is built for a G1/2 (BSPP) port, carries the standard 40 um filter element, and includes a reverse/check valve and a mounting bracket, so it can be fitted straight onto an air-preparation drop and put to work.
This is a genuine AirTAC part from the GC series, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in up to 1 in, plus choices of drain type, filter grade, gauge scale and thread form. Rated inlet pressure is 1.0 MPa (145 psi) with a working temperature of -5 to 70 C (non-freezing). Flow is published as curves rather than a single rating, 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-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 spray booths and air-driven agitators on a body-shop line, with the automatic drain handling condensate so the set keeps working between shifts.
Supplies conditioned air to carton sealers, vacuum generators and pneumatic pushers along a conveyor line, where the low-pressure regulator holds a stable setting for the actuators.
Prepares the air feeding clamps, tool-changer cylinders and air-blast nozzles on a machining centre, with the reverse/check valve helping hold the circuit if the supply dips.
Size 400 with a 1/2 in port suits lines with substantial air demand; step down to 300 or up to 600 if your consumption differs - the port and flow capacity grow together. The automatic drain on the filter bowl discharges collected water without manual attention, which suits unattended or hard-to-reach installations; manual and differential-pressure drains are available elsewhere in the series if you prefer. The standard 40 um element covers general plant air; specify a 5 um element (code W) where downstream equipment needs finer filtration. The fitted square gauge reads in psi, with MPa or bar scales and an external round gauge available as options. This is the low-pressure type, so confirm your working band suits it before ordering. Thread here is G (BSPP); PT is the standard form and NPT can be ordered. Flow is published as curves, not a single rating, so ask us to confirm sizing against your application before you order.
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, not as 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 at 1/2 in on request before you order.
The L in the code marks the low-pressure regulator variant, intended for circuits that run below the standard band; the exact range is not published, so confirm it with us. The A marks an automatic drain on the filter bowl, which expels collected water by itself instead of relying on manual draining.
