The AirTAC GC400C10LC2G AirTAC F.R.L. Combination G3/8 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 GC400C10LC2G is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and lubricator assembled as one set, giving filtration (water and particulate removal), pressure regulation and oil-mist lubrication in a single order. This size 400 unit is threaded G3/8 (PT is the standard thread, with G and NPT available as order options). The regulator is the low-pressure (L) type; its exact adjustment range is not published in the catalogue, so we confirm it on request. The filter carries the standard 40 um element with a differential-pressure drain, and this configuration is fitted with an external round gauge scaled in psi. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. The filter and lubricator bowls on this size are polycarbonate, and a mounting bracket is included.
This is a genuine AirTAC part. The GC series spans sizes 200, 300, 400 and 600, with port sizes from 1/8 to 1 inch, a choice of differential-pressure, automatic or manual drains, a 40 um standard or 5 um (W) fine filter element, gauge scales in MPa, psi or bar, and PT, G or NPT threads. Flow for this series is published as curves rather than a single rated figure, 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.

Feeding filtered, regulated and lubricated air to weld-gun clamp cylinders on a robotic spot-welding cell, where moisture and scale in the supply would foul the clamp valve and shorten cylinder seal life.
Conditioning the air supply to pusher and stopper cylinders on a bottling or canning conveyor, where the low-pressure regulator suits circuits that run below standard plant pressure and the lubricator keeps the actuators moving smoothly through long shifts.
Supplying treated air to the pneumatic cylinders and air-jet aids on a spinning-frame line, where the 40 um filter removes water and particulate from a humid mill air supply and the oil mist protects the machine's valves.
Start with the port and the demand: this unit is size 400 with a 3/8 in port; step up or down a size when your port or air demand changes, and let us confirm the flow from the published curves before you order. The drain fitted here is the differential-pressure type (the series default); automatic (A) and manual (M) drain versions can be ordered instead. The filter element is the standard 40 um grade; specify W for the 5 um fine grade where downstream equipment needs cleaner air. This configuration carries a round gauge scaled in psi; the embedded square gauge is the series standard, with MPa, psi or bar scales available. Thread is G on this unit, ordered as a catalogue option - PT is the standard thread and NPT is also available. 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 curves rather than a single rated figure, so quoting one number would not be honest. Send us your line pressure and air demand and we will confirm the flow from the datasheet against your application on request, before you order.
The drain fitted here is the differential-pressure type, the series default: it discharges condensate from the filter bowl based on the pressure differential across the filter element, so there is no manual drain valve to operate each shift. Automatic (A) and manual (M) drain versions can be ordered instead if your installation prefers them.
