The AirTAC GC400C15LF2WGK 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 See datasheet ports, a 40 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The AirTAC GC400C15LF2WGK is a three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one supply package for compressed air only. This size 400 configuration is built for 1/2 inch ports with G (BSPP) thread, carries a 5 um filter element (code W) with a differential-pressure drain on the filter bowl, and fits a low-pressure type regulator. A square pressure gauge reading in psi is embedded as standard, a reverse/check valve is fitted (code K), and the mounting bracket is included. Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C, non-freezing. The bowls on the wetted filter and lubricator sections are metal.
This is a genuine AirTAC part. The GC family is available in sizes 200, 300, 400 and 600 with a choice of ports, drain types, filter grades (40 um standard, 5 um optional), gauge scales (MPa, psi or bar) and thread options, so a configuration can be matched to the line it supplies. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing figures for your application on request.

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 clamps, tool-change cylinders and chip-clearing jets on a machining centre, where the 5 um element protects directional valves and the lubricator mists the actuator seals.
Supplying spray guns and air-assisted applicators that need water and particulate stripped out, a steady low-pressure setting at the gun, and a light oil mist for air motors.
Running the cylinders on case packers, cappers and diverters along a bottling line, with the check valve holding the circuit and the gauge giving operators a psi reference at the drop.
Start with the port step: this unit is the size 400, 1/2 inch version, one step up from the 300 series - pick the size whose flow curve covers your demand rather than upsizing blindly, and ask us to check the curve against your consumption. The 5 um element in this code is the finer of the two published grades (40 um is the standard); choose 5 um where downstream valves and instruments need cleaner air. The differential-pressure drain bleeds the filter bowl automatically as pressure differential builds, with no operator intervention. The embedded square gauge here reads in psi; MPa and bar scales and an external round gauge are alternatives. Thread is G (BSPP) on this code - PT is the standard thread and G or NPT are catalogue options to order as specification. The bracket is included with this configuration.
One honest note before ordering: the regulator in this code is the low-pressure type and its exact adjustment range is not published in the material we hold, and flow is published as curves, not a single rating. Confirm both with us against your application before you commit.
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 will not quote you a number that is not in the datasheet. Tell us your working pressure and air consumption and we will confirm the sizing from the datasheet curve on request before you order.
G is the thread: G1/2, i.e. BSPP on the 1/2 inch ports (PT is the standard thread, with G and NPT available as order options). W is the 5 um filter grade instead of the 40 um standard. F2 is the embedded square gauge with a psi scale. K means a reverse/check valve is fitted. The regulator is the low-pressure type; its exact adjustment range is not published, so confirm it with us on request.
