The AirTAC GC400C15LC2G AirTAC F.R.L. Combination, G1/2, 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 GC400C15LC2G is an AirTAC GC-series three-unit F.R.L. combination: a separate filter, pressure regulator and oil-mist lubricator assembled together as one unit. This size 400 configuration is specified with G1/2 (BSPP) ports, a 40 um filter element with differential-pressure drain, the low-pressure regulator type, an external round gauge reading in psi, and a mounting bracket. The filter removes water and particulate from the compressed air, the regulator holds a steady downstream pressure, and the lubricator meters a fine oil mist to the equipment downstream. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. The filter bowl on size 400 units is polycarbonate (PC); only size 600 uses an aluminium alloy bowl.
This is a genuine AirTAC part. The GC family is available in sizes 200, 300, 400 and 600, with port sizes from 1/8 to 1 inch, and options that include a 5 um filter element (code W), automatic or manual drain, gauge scales in MPa, psi or bar, and PT, G or NPT threads. AirTAC publishes flow for these units as curves rather than a single rated figure, so we confirm flow and 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. 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 the air cylinder of a bench press in a metal fabrication shop, where filtered, regulated and lubricated air keeps the stroke consistent and carries oil mist to the cylinder seals through a full shift.
Supplying the flap-fold and case-push cylinders on a carton erector and sealer in a packaging plant, with the lubricator metering oil mist to cylinders that cycle continuously and the regulator holding one steady setting for the whole machine.
Feeding impact wrenches and air ratchets at a commercial-vehicle service bay, where the filter strips water and scale from the shop air line and the regulator gives the technicians a stable, repeatable pressure at the bench.
The real choices within the GC family are the size and port step - 200, 300, 400 or 600, with ports from 1/8 to 1 inch - matched to the air demand of your line; the drain type on the filter (differential-pressure as here, automatic, or manual); the filter grade (40 um standard, 5 um with code W); the gauge and its scale (embedded square gauge standard, external round gauge optional, in MPa, psi or bar); the thread (PT is the AirTAC standard, with G and NPT as order options - this unit is specified with G1/2); and the bracket. The regulator on this unit is the low-pressure type (code L). Flow for GC units is published as curves, not a single rating, so ask us to confirm sizing against your application before ordering.
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 number, so there is no one l/min or SCFM figure we can honestly quote for this unit. Tell us your working pressure and the air demand of the equipment you are feeding, and we will confirm the sizing from the datasheet before you order.
This unit carries the L code, so its regulator is the low-pressure type rather than the standard type. The exact adjustment range for the low-pressure version is not published in the catalogue table we work from, so we confirm it from the datasheet on request. For reference, standard-type GC units cover 0.15-0.9 MPa (20-130 psi) with differential-pressure or automatic drain.
