The AirTAC GC400C15AF2GK AirTAC F.R.L. Combination, G1/2 Port 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, pressure regulator and lubricator built up as one unit, so the compressed air supply is cleaned of water and particulate, regulated to the set pressure, and carried downstream with a fine oil mist. This GC400C15AF2GK is the size 400 unit with a G1/2 (BSPP) port, automatic drain on the filter bowl, the standard 40 um filter element, a standard regulator adjustable from 0.15 to 0.9 MPa (20-130 psi), a square gauge reading in psi, a fitted reverse/check valve and an included mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi), the working temperature range is -5 to 70 C (non-freezing), and the bowls on this size are polycarbonate (PC).
This is a genuine AirTAC part. The GC combination is available in sizes 200, 300, 400 and 600 with matching port sizes, and with manual or automatic drain, a 5 um (code W) or standard 40 um element, gauge scale in MPa, psi or bar, and PT (the series standard), G or NPT threads. Flow figures for this series are published as curves rather than a single rating, 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.

Supplying cleaned, regulated and lubricated air to pneumatic clamps, tool-changers and part-ejector cylinders on a machining centre, with the fitted check valve for circuits that must not back-feed.
Feeding air drops that run impact wrenches, nutrunners and pneumatic press tools, where the regulator sets tool working pressure and the lubricator carries an oil mist to the tools downstream.
Filter-regulated, lubricated air for conveyor diverters, gripper arrays and carton-closing cylinders, with the automatic drain handling water removal from the filter bowl.
Step up through the sizes 200, 300, 400 and 600 - each step brings a larger port and more flow capacity - and match the port to your piping; this unit is size 400 with a 1/2 in G-threaded port. Drain type is a real choice: this code has A for automatic drain, while differential-pressure (no letter) and manual (M) are the other catalogue options. Filtration is the standard 40 um element; specify code W if your circuit needs the finer 5 um grade. The fitted square gauge reads in psi, with MPa and bar scales and an external round gauge available as options. On thread, PT is the series standard and this unit carries the G (BSPP) option; NPT is also available to order. A mounting bracket is included. Because flow for this series is published as curves and not as 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-C1 regulator with a GF400-C1 filter on that branch.
AirTAC publishes flow for this series as curves rather than a single rated figure, so we do not quote one number. Send us your line pressure and air demand and we will confirm the sizing from the datasheet on request before you order.
It selects the automatic drain on the filter bowl, so collected water is discharged without anyone having to open a manual drain. The series also offers a manual drain (code M) and, when no drain letter is shown, the differential-pressure drain as the default.
