The AirTAC GC400C10LF2WGK AirTAC F.R.L. Combination, G3/8, 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 GC400C10LF2WGK is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one supply package. This configuration is built on the size 400 body with a G3/8 (3/8 inch) G-thread port, a 5 um filter element (the fine grade, code W, versus the 40 um standard), a differential-pressure drain on the filter bowl, a low-pressure type regulator, an embedded square gauge scaled in psi, a reverse/check valve fitted, and a mounting bracket included. In service it dries and cleans the compressed air, holds the downstream pressure you set, and carries a fine oil mist to the air tools and cylinders on the line.
This is a genuine AirTAC part. The GC series is offered in sizes 200, 300, 400 and 600 with a choice of port sizes, PT (standard), G or NPT threads, drain types, 40 um or 5 um filtration, gauge scales in MPa, psi or bar, and optional reverse/check valves. Max working (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 and we will 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.

Feeding spray guns and air-assisted applicators on a paint line, where the 5 um element and oil mist help deliver clean, lubricated air at the steady, moderate pressure the booth controls expect.
Supplying the cylinders and grippers on a packaging line, with the regulator holding a consistent set pressure so case clamping and sealing strokes stay repeatable through the shift.
Feeding a benchtop pneumatic press or clamping fixture, where the check valve helps hold the set downstream pressure if the shop air supply dips mid-cycle.
Start with the port and size: this unit is size 400 with a G3/8 port; step up to size 600 or down to 300/200 depending on the flow your line needs, and we will confirm sizing against the published curves before you order. The 5 um element (code W) suits air that feeds sensitive valves, cylinders or finishing equipment; choose the 40 um standard grade where coarser protection is enough. Drain here is differential-pressure (the default), which bleeds the bowl automatically as the pressure drop across the element builds; automatic and manual drains are available in the series if you prefer. The fitted square gauge reads in psi; MPa and bar scales, and an external round gauge, are orderable options. The reverse/check valve (code K) holds downstream pressure if the supply drops. Thread is G on this unit; PT is the standard thread and NPT is also a catalogue option, all specified as ordering choices. A mounting bracket is included.
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 performance curves rather than a single rated figure, so there is no one rated flow number we can quote. Tell us your line pressure and the air demand of the equipment you are feeding, and we will confirm the sizing from the datasheet curves before you order.
The L marks the low-pressure type of regulator in this combination, intended for applications set below the standard regulator's range. The exact adjustment range for the low-pressure type is not published in the catalogue sheet we work from, so confirm your set pressure with us and we will verify it against the datasheet. The unit carries an embedded square gauge scaled in psi so you can read and adjust the setting directly.
