The AirTAC GC40015LF2WGK AirTAC F.R.L. Combination, 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 5 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC40015LF2WGK is an AirTAC GC400 three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one coordinated set. This configuration carries a G1/2 (BSPP) port, a 5 um filter element (the finer of the two published grades, code W), a differential-pressure drain on the filter bowl, a low-pressure type regulator, a built-in square gauge scaled in psi, a reverse/check valve, and a mounting bracket. In service it cleans water and particulate from the compressed air, holds the working pressure you set, and carries oil mist downstream to lubricate air tools and cylinders.
This is a genuine AirTAC part. The GC family is published in sizes 200, 300, 400 and 600, with port sizes from 1/8" up to 1", drain choices (differential-pressure, automatic or manual), 40 um standard or 5 um (W) filtration, gauge and thread options, and an optional reverse/check valve. 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 filtered, regulated and lubricated air to spray guns and air-assisted applicators on a paint line, where the 5 um element helps protect finish quality and the low-pressure regulator suits gun supply settings.
A single conditioning point for carton sealers, case packers and bagging lines, delivering clean, pressure-controlled, lubricated air to the cylinders and actuators that run the conveyor-linked packaging cycle.
Conditions the shop air feeding clamps, tool-changer cylinders and chip-clearing jets on a machining cell, with the check valve helping hold the downstream circuit if the main supply is interrupted.
Start with size and port: the GC400 sits in the middle of the range and this unit is fitted with a G1/2 port; step up to GC600 or down to GC300/GC200 as your line's flow demand dictates, and match the thread to your piping (PT is the standard; G and NPT are order options). This unit is specified with the 5 um (W) element - choose it where downstream valves and cylinders need finer air than the 40 um standard; the drain is the differential-pressure type (automatic and manual drains are the other catalogue choices). The regulator here is the low-pressure type, and the gauge is the embedded square type scaled in psi (MPa and bar scales, and an external round gauge, are the alternatives). The reverse/check valve (code K) holds downstream settings if the supply drops, and the bracket is included for panel or wall mounting.
Because AirTAC publishes flow only as curves and not as a single rated number, we do not quote a flow figure here. Send us your application details and we will confirm the datasheet and check the sizing against your required flow 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 GC400 as curves, not as a single rated number, so we do not state a flow figure. Send us your application details and we will confirm the datasheet and check this unit's sizing against your required flow before you order.
W is the filter-grade code: this unit carries the 5 um element instead of the 40 um standard element. Choose 5 um where downstream valves, cylinders or tools need finer removal of particulate; the 40 um element remains the standard choice for general air prep.
