The AirTAC GC40015LF2G 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 differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC40015LF2G 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 package. This size-400 unit is built with a 1/2 inch G (BSPP) port. The filter section carries the standard 40 um element with a differential-pressure drain that bleeds collected condensate as pressure across the bowl builds. The regulator is the low-pressure type, fitted with an embedded square gauge scaled in psi. The lubricator meters oil mist into the downstream air for tools and cylinders that need lubrication. All bowls on this 400 size are polycarbonate (PC), 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, thread choices (PT standard, G and NPT as order options), 5 um filtration (code W), automatic or manual drains, gauge scale choices and reverse/check valve variants across the range. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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 spray-booth and paint-line air drops where the filter removes water and particulate, the low-pressure regulator holds a gentle setting for finishing work, and the lubricator is left valved off or used for air motors on the same header.
Supplies the cylinder and actuator circuits on carton-forming and case-sealing conveyors, cleaning the shop air, holding a stable low supply pressure and oil-misting the pneumatic cylinders that cycle all shift.
Conditions the supply to fixture-clamping circuits on CNC machining cells: filtered air protects the clamp cylinders, the regulator holds the clamping pressure set on the psi gauge, and the lubricator services the swing clamps.
Start with the size and port: this unit is size 400 with a 1/2 inch G thread, one step up from the 300 series, so step up or down if your line port or expected air demand differs. Because flow is published as curves rather than a single rating, ask us to confirm sizing against your application before ordering. Other decodable choices: the drain here is differential-pressure (automatic and manual drains are available in the series); filtration is the standard 40 um element, with 5 um (code W) as an option; the gauge is the embedded square type scaled in psi, with MPa or bar scales and an external round gauge available; the thread is G (BSPP) here, while PT is the standard and NPT is an order option; and a mounting bracket is included. If your circuit needs only filtration plus regulation, a GFR may suit better than this three-unit set.
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, not as a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the datasheet and check the sizing against your required flow before you order.
The L in the code marks the low-pressure regulator type, intended for circuits set below the standard range; its exact adjustment range is not published in the material we hold, so confirm it with us on request. The blank drain position means the differential-pressure drain is fitted, which discharges collected condensate automatically as the pressure difference across the bowl builds.
