The AirTAC GC400C15ALF2WK AirTAC F.R.L. Combination, PT1/2, 5 um 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 See datasheet ports, a 40 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The AirTAC GC series is a three-piece F.R.L. combination: a separate air filter, a pressure regulator and an oil-mist lubricator, assembled as one air-treatment stack. This configuration is the size 400 unit with 1/2 in PT ports, so it sits in a 1/2 in compressed-air line and delivers all three treatments in one pass: water and particulate are removed by the 5 um filter element, downstream pressure is set on the low-pressure type regulator and read on the fitted square psi gauge, and the lubricator meters oil mist to downstream pneumatic equipment. The automatic drain handles condensate removal from the filter bowl without daily manual draining, a check valve (reverse valve) is fitted, and the mounting bracket is included.
This is a genuine AirTAC part. The GC family is available in sizes 200, 300, 400 and 600 with matching port sizes, and can be ordered with manual or differential-pressure drains, a 40 um standard or 5 um fine filter element, different gauge scales, G or NPT threads, and with or without gauge, bracket or check valve. Flow is published by AirTAC 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. Standard type, regulating 0.15 - 0.9 MPa (20 - 130 psi). 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-C1 filter, GR400-C1 regulator and GL400-C1 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.

Feeding spray guns and air-assisted applicators on a paint line, where the 5 um element, set regulator and oil misting together condition the air at each booth drop.
Supplying filtered, regulated and lubricated air to pneumatic clamps, vises and tool-changer actuators on a machining centre, with the check valve holding the circuit setup.
Conditioning air for cylinder-driven pushers, diverters and sealing heads along a packaging conveyor, where the automatic drain keeps condensate out of the valves.
Start with the port step: this size 400 unit carries 1/2 in ports, and the GC family steps through 200/300/400/600 with 1/8 in to 1 in ports, so match the size to your line and expected air demand. Drain type is a real choice: automatic (this unit) empties the bowl on its own, manual needs operator action, and differential-pressure draining is the catalogue default. Filter grade is 40 um standard or 5 um fine (this unit is 5 um) - choose the finer grade where downstream valves and cylinders need cleaner air. The regulator here is the low-pressure type; gauge scale options are MPa, psi or bar, and this unit carries the square psi gauge. Thread is PT as standard, with G (BSPP) and NPT as order options, and the bracket is included.
One honest note on sizing: AirTAC publishes flow for this family as curves, not as a single rated number, so we cannot quote a rated flow here. Send us your application details and we will confirm the flow figures from 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-C1 regulator with a GF400-C1 filter on that branch.
AirTAC publishes flow for the GC series as curves rather than a single rated figure, so we do not quote a rated flow, Cv or SCFM number for this unit. Tell us your line size and air demand and we will confirm the flow figures from the datasheet so you can size it against your application before ordering.
The L code in GC400C15ALF2WK marks the regulator as the low-pressure type rather than the standard type. The exact adjustment range for the low-pressure version is not published in our current data sheet, so please confirm it with us on request. If you need the standard range instead, order the GC400 configuration without the L code.
