The AirTAC GC40015MLF2G AirTAC F.R.L. Combination, 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 PT1/2" ports, a 40 µm element, a manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi).
The AirTAC GC40015MLF2G is a size 400 three-unit F.R.L. combination that conditions compressed air in one assembly: a filter removes water and particulate, a regulator sets downstream pressure, and a lubricator adds an oil mist for downstream air tools and cylinders. This configuration is built with a G1/2 (BSPP) port, a manual-drain filter bowl in polycarbonate, a standard 40 um filter element, a low-pressure regulator type, and an embedded square gauge scaled in psi. No reverse/check valve is fitted, and a mounting bracket is included.
This is a genuine AirTAC part. The GC series is offered in sizes 200, 300, 400 and 600, with port options from 1/8 to 1 inch, PT as the standard thread and G or NPT as order options, a choice of differential-pressure, automatic or manual draining, 40 um or 5 um (W) filtration, and gauge scale choices of MPa, psi or bar. 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. 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.

|---|---|
| 15 | Port size PT1/2". This body offers 10 = PT3/8", 15 = PT1/2". |

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.

At a paint-line drop, the combination filters water and particles from the supply, holds a steady low regulated pressure to the spray guns, and meters oil mist to keep gun air motors running smoothly through the shift.
Feeding a machining center's pneumatic circuits, the unit removes condensate and swarf-laden particles, regulates the supply pressure to the machine's specified low setting, and lubricates the air-driven tool-change and clamping actuators.
On a bottling hall conveyor system, the combination conditions the plant air before it reaches the stopper, pusher and diverting cylinders, protecting them from water carryover while supplying regulated pressure and oil mist for continuous cycling.
Start with the port step: this unit is size 400 with a G1/2 port, one step above the 3/8 size 300 and below the 3/4 size 600, so pick the size whose flow curve covers your demand rather than oversizing on port alone. The manual drain means an operator opens the bowl drain at intervals, which suits attended installations; choose automatic or differential-pressure draining where the unit is hard to reach. Filtration here is the standard 40 um element; specify the W option for 5 um where finer particle removal is needed. The fitted square gauge reads in psi, with MPa or bar scales available, and an external round gauge is optional. Thread is G (BSPP) on this code, with PT standard and NPT orderable. A mounting bracket is included. 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 GR400-15 regulator with a GF400-15 filter on that branch.
AirTAC publishes flow for this series as curves rather than a single rated figure, so we do not quote a rated number. Tell us your line pressure and air demand and we will confirm the flow curve and correct size from the datasheet on request.
The M in the code specifies a manual-drain filter bowl, so condensate is emptied by opening the drain at intervals. If the unit will be mounted where regular attention is impractical, the same size 400 combination can be ordered with automatic (A) or differential-pressure (blank) draining instead.
