The AirTAC GC40015LF2 AirTAC F.R.L. Combination, PT1/2, 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 differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC40015LF2 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 the size 400 unit with a 1/2 in PT port, a 40 um filter element and a differential-pressure drain on the filter bowl, so collected condensate bleeds off automatically as the pressure differential across the element rises. The regulator is the low-pressure type and carries a fitted square gauge scaled in psi, so downstream pressure is visible at the setpoint. PC (polycarbonate) bowls let you see fluid level and condensate at a glance, and the set includes a mounting bracket for panel or wall fixing.
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, G (BSPP) and NPT thread options, automatic, manual or differential-pressure drains, a 5 um (code W) filter element option, gauge scale choices and low-pressure or standard regulator types. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures for your application before ordering.

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.

Feeds a cartoning or wrapping machine's cylinder and valve bank from a 1/2 in plant air drop: dirt and water stripped at 40 um, line pressure held by the low-pressure regulator, and oil mist carried to the actuators for running lubrication.
Supplies a bench-mounted air press or clamping fixture where the tooling runs at reduced pressure. The psi-scaled square gauge lets the setter read and lock the working pressure, while the differential-pressure drain keeps the bowl clear through the shift.
Prepares air for a conveyor line's diverters, gates and pop-up rollers fed from a 1/2 in header. The three-unit set keeps grit out of the directional valves, stabilises supply pressure and mists oil into the cylinders that cycle all day.
Start with size and port: the 400 size with a 1/2 in PT port suits lines that need more flow than the 200/300 step; match the size step to your required air consumption. Choose the drain type where it matters - the differential-pressure drain on this unit needs no daily attention, while a manual drain (code M) suits points where an auto drain is not wanted and an automatic drain (code A) suits unmanned installations. The 40 um element is standard; specify the 5 um W grade if downstream valves or cylinders need finer filtration. The fitted square gauge here reads in psi; MPa and bar scales are also available, and an external round gauge is optional. PT is the standard thread; G (BSPP) and NPT are order options. This is the low-pressure regulator type, chosen where the working range sits below the standard band. Flow is published as curves, not a single rating, so send us your application details and we will confirm sizing against the datasheet 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 GR400-15 regulator with a GF400-15 filter on that branch.
AirTAC publishes flow for the GC series as curves, not as a single rated number, so we do not quote a figure here. Tell us your line pressure and the air consumption of the equipment you are feeding, and we will confirm the flow from the datasheet curves and check that the 400 size at 1/2 in is the right step before you order.
The L in GC40015LF2 marks the low-pressure regulator type, selected where the downstream working pressure sits below the standard regulator band; the exact adjustment range for this type is not published, so we confirm it on request. The drain is the differential-pressure type: condensate collected in the filter bowl bleeds off automatically when the pressure drop across the 40 um element rises, with no manual blowing down needed.
