The AirTAC GC40015LC2G AirTAC F.R.L. Combination Unit, G1/2 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 PT1/2" ports, a 40 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC40015LC2G is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one supply unit. This configuration is built around a G1/2 (BSPP) port in the size-400 frame, with a 40 um filter element, a differential-pressure drain on the filter bowl, and a low-pressure type regulator for lines that run below standard working pressures. The fitted external round gauge reads in psi, the filter and regulator bowls are polycarbonate at this size, and the mounting bracket is included.
This is a genuine AirTAC part. The GC family spans sizes 200, 300, 400 and 600, with port options from 1/8 in to 1 in, automatic, manual or differential-pressure drains, a 5 um filter element as an option, gauge scales in MPa, psi or bar, and PT, G or NPT threads. Rated flow for this combination is published as curves rather than a single figure, so ask us and we will confirm the datasheet figures against 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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: GF400-15 filter, GR400-15 regulator and GL400-15 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.

Installed at the point where the compressor ring feeds a production hall, the GC40015LC2G filters water and particulate from the main line, holds a steady low working pressure for downstream tools, and carries oil mist to keep actuators lubricated.
On a machining cell with air-operated clamps and a pneumatic press, this combination conditions the supply in one unit: clean air for the valves, a stable regulated pressure for consistent clamping force, and lubrication for the cylinder seals.
Feeding the cylinders and air jets on a packaging or conveyor line, the unit removes line moisture before it reaches the diverters, regulates pressure for gentle product handling, and mists oil into the supply to extend actuator life.
Size and port set the capacity envelope: the 400 size with its 1/2 in G-thread port suits mid-to-large supply lines, but the right step depends on the flow your circuit actually draws, so size up or down against the published curves. Drain choice matters on the filter: differential-pressure (as coded here) drains only when the pressure drop calls for it, automatic drains continuously, and manual relies on an operator. The 40 um element is the standard grade; specify the W code for 5 um where finer particulate removal is needed. Gauge scale is selectable (MPa, psi or bar - this unit is psi), and the low-pressure type regulator is the correct pick when your working pressure sits below the standard regulator band. Thread is G (BSPP) on this code; PT is the catalogue standard with G and NPT as order options. Flow is published as curves, not 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 GR400-15 regulator with a GF400-15 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 flow your circuit needs, and we will confirm the datasheet curve figures for this exact configuration before you order.
The L code in GC40015LC2G means the regulator is the low-pressure type, intended for circuits that run below the standard regulator band. The exact adjustment range for the low-pressure type is not published in the standard table, so ask us to confirm it against your working pressure. If your line runs at conventional pressures, the standard type (no L code) is the usual choice.
