The AirTAC GC40010LF2G AirTAC F.R.L. Unit, Low-Pressure, G3/8 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 PT3/8" ports, a 40 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC40010LF2G is an AirTAC GC-series three-piece F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one unit. This configuration is the 400 size with a G3/8 (3/8 in) G-thread port, a 40 um standard filter element, a differential-pressure drain on the filter bowl, and a low-pressure type regulator. A square pressure gauge with a psi scale is fitted, the polycarbonate bowls suit the 400 size, the mounting bracket is included, and no reverse/check valve is fitted. It treats compressed air in one pass: water and particulate are drained off, downstream pressure is set on the regulator, and a fine oil mist is carried into the air line to lubricate downstream pneumatic components.
This is a genuine AirTAC part. The GC family is published in 200, 300, 400 and 600 sizes with port sizes from 1/8 in to 1 in, and options across thread type (PT standard, G and NPT to order), drain type, filter grade (40 um standard, 5 um with code W), gauge style and scale, and reverse/check valve. Flow figures for this series are published as curves rather than a single rated number, so ask us and we will confirm the datasheet 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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: GF400-10 filter, GR400-10 regulator and GL400-10 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.

Feeds filtered, regulated and lubricated air to spray-booth actuation and mask-lifting cylinders on a finishing line, where the low-pressure regulator type suits circuits set well below full line pressure and the lubricator keeps air cylinders running smoothly shift after shift.
Serves as the single air-preparation point for a carton erector and case packer: the 40 um element strips water and debris before the valves, the regulator holds a steady setting for the sealing cylinders, and the oil mist lubricates the diverters and pushers.
Prepares the air feeding power clamps and tool-change actuators on a machining cell, with the square psi gauge giving the operator a visible setpoint, the differential-pressure drain clearing condensate as the element loads, and the lubricator conditioning the clamp cylinders.
Start with the port step: the 400 size carries a 3/8 in port, and the GC range steps through 200, 300, 400 and 600 as port size and flow capacity rise - match the size to the air demand of the line rather than the pipe alone. For the drain, the differential-pressure type on this unit discharges condensate automatically whenever the pressure drop across the element is high enough; a fully automatic (A) or manual (M) drain can be ordered instead if your duty or access suits it better. The 40 um element is the standard grade; specify W for the 5 um element where finer filtration is needed. The fitted square gauge reads in psi; external round gauges and MPa or bar scales are alternatives. Thread is G here, with PT as the catalogue standard and NPT orderable. Note the L code: this is the low-pressure regulator type, so its adjustment range differs from the standard type - confirm the exact range with us before ordering. Finally, flow for this series is published as curves, not a single rating, so send us your application details and we will confirm 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 GR400-10 regulator with a GF400-10 filter on that branch.
AirTAC publishes flow for the GC series as characteristic curves rather than a single rated figure, so we do not quote a rated flow number for this unit. Send us your application details - the machines or cylinders served, working pressure and duty - and we will confirm the datasheet flow figures against your requirement on request before you order.
L marks the low-pressure type of regulator in this combination, rather than the standard type. It is chosen for circuits that operate at lower set pressures. The exact adjustment range for the low-pressure type is not published in the catalogue sheet we work from, so please confirm the range with us on request. The rest of the code decodes as: 400 size, 3/8 in port, G thread, square gauge with psi scale, differential-pressure drain and 40 um filtration.
