The AirTAC GC400C10F2WGK 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 AirTAC GC400C10F2WGK is a three-piece F.R.L. combination that treats compressed air in one assembly: a filter removes water and particulate down to 5 um, a regulator holds a stable downstream pressure adjustable from 0.15 to 0.9 MPa (20-130 psi), and a lubricator meters oil mist into the air line. This size 400 unit is built with a G3/8 port, a differential-pressure drain on the filter bowl, an embedded square gauge reading in psi, and a reverse/check valve fitted to hold downstream pressure when the supply drops. A mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GC series is available in sizes 200, 300, 400 and 600 with a choice of port sizes, drain types, filter grades, gauge scales and thread options, so a configuration can be matched to most plant air lines. Because flow is published as curves rather than a single rated figure, we 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 a row of pneumatic assembly stations from a 3/8 in branch line: the 5 um element keeps grit out of directional valves, the regulator holds a steady working pressure, and the lubricator mists oil to the cylinders and air tools on the bench.
Supplying the air cylinders, grippers and stop gates on a packaging conveyor, where the check valve holds actuator position through brief supply dips and the differential-pressure drain keeps the bowl emptied without stopping the line.
Air supply for clamping fixtures and spindle-air seals on CNC machining centres: clean, regulated and lubricated air at a set psi protects the clamp cylinders and keeps swarf and condensate out of the spindle seal circuit.
Start with the port and size step: size 400 with a G3/8 port suits mid-range plant air lines, and stepping up a size gives more flow capacity at the same pressure drop - ask us to check the flow curve against your demand before ordering. Choose the filter grade: 40 um is the standard element and 5 um (this unit, code W) protects downstream valves, cylinders and air tools from finer contamination. Drain type matters: differential-pressure drain (this unit) bleeds the bowl automatically as flow passes, while automatic and manual drain variants are available. The gauge is an embedded square unit reading in psi here, with MPa or bar scales and an external round gauge as options. Thread is G on this unit; PT is the standard offering and G or NPT are catalogue options to order. A mounting bracket is included, and the fitted reverse/check valve holds downstream pressure on supply loss.
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 there is no one rated flow number we can quote. Tell us your line pressure, downstream demand and allowable pressure drop and we will confirm the sizing against the datasheet curve on request before you order.
The GC series ships with a 40 um element as standard, and code W selects the finer 5 um element. The 5 um grade is the right choice when the downstream valves, cylinders or tools need finer protection from water and particulate; if your application only needs coarse protection, a 40 um configuration is available in the same size.
