The AirTAC GC400C15LC2GK 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 See datasheet ports, a 40 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC series is AirTAC's three-piece F.R.L. combination: a separate air filter, pressure regulator and lubricator assembled into one conditioning set, so one connection delivers clean, regulated, lubricated compressed air. This GC400C15LC2GK is built in size 400 with G (BSPP) 1/2 in ports. It carries the standard 40 um filter element, a differential-pressure drain on the filter bowl, and the low-pressure type regulator. A round external gauge scaled in psi is fitted, a reverse/check valve is included, and the set comes with a mounting bracket.
This is a genuine AirTAC part. The GC range spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, and options including automatic or manual drains, a finer 5 um element, gauge scales in MPa, psi or bar, and PT or NPT threads in place of G. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures for your application.

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.

Fixture and chuck clamping cylinders on a machining centre need air that is dry enough to protect the valve stack, held at a stable set pressure, and lightly oiled to keep the clamp cylinder seals working over long production runs. A three-unit F.R.L. set at the machine inlet does all three jobs from one connection.
Pneumatic pushers, diverters and stopper cylinders along a packaging conveyor cycle thousands of times a shift. Conditioning the supply at the line drop keeps water and scale out of the directional valves, holds the regulator setting against demand swings, and carries a fine oil mist to the cylinders.
Bench and overhead air-tool drops in an assembly plant benefit from a full F.R.L. set: the filter stops rust and water reaching the tool, the regulator lets each station set its own pressure, and the lubricator feeds the tool's internal vanes and bearings. The low-pressure type regulator suits stations running below standard plant pressure.
Size 400 with 1/2 in ports is the mid-large step in the GC range; step up to size 600 or down to 300/200 depending on the pipe size and air demand of the line, and match the thread to your pipework (G here, with PT and NPT available as catalogue options). The 40 um element suits general plant air; choose the W code for 5 um where downstream valves and cylinders need finer protection. Drain choice matters: differential-pressure (this unit) drains only while air flows, automatic drains without attention, and manual drains only when someone opens it. This unit is the L-coded low-pressure regulator type, so confirm your set pressure against it before ordering; gauge scale (psi here, MPa or bar optional) and the fitted reverse/check valve round out the decode.
One honest note on sizing: AirTAC publishes flow for this series as curves, not as a single rated figure, so we do not quote a flow number here. Send us your application details and we will confirm the 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-C1 regulator with a GF400-C1 filter on that branch.
AirTAC publishes flow for the GC series as characteristic curves, not as a single rated figure, so we do not quote a flow number for this unit. Size 400 with 1/2 in ports is a substantial step in the range, but the right way to size it is against your actual demand. Send us your application details and we will confirm the flow figures from the datasheet on request before you order.
The L in the model code means the regulator in this GC set is the low-pressure type rather than the standard version, for applications where the working pressure sits below the standard adjustment band. The exact adjustment range for the low-pressure type is not published in the catalogue, so please ask us to confirm it against your required set pressure before ordering. Everything else about the decode is standard: 40 um filter, differential-pressure drain, round psi gauge, reverse/check valve fitted, and G 1/2 in ports.
