The AirTAC GC400C15LC2 AirTAC F.R.L. Combination, PT1/2, 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 GC400C15LC2 is an AirTAC GC three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one conditioning stack. This configuration is built for a 1/2 in PT port, carries the standard 40 um filter element, and drains condensate by differential pressure, so the bowl vents itself as flow passes through - no daily manual draining on a well-loaded line. The regulator is the low-pressure type, suited to circuits that run well below standard main-line settings; the exact adjustment window for the low-pressure version is not published, so we confirm it from the datasheet on request. An external round gauge scaled in psi is fitted, and a mounting bracket is included.
This is a genuine AirTAC part. The GC family spans sizes 200, 300, 400 and 600, with port options from 1/8 in to 1 in, PT as the standard thread and G (BSPP) or NPT as order options, a choice of 40 um or 5 um (W) filtration, manual or automatic drain variants, gauge scale choices, and an optional reverse/check valve. Flow for this size is published as curves rather than a single rated figure, so ask us to confirm sizing and any datasheet figure against 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 1/2 in branch drops that supply impact drivers and clamp cylinders on a car trim line, with filtered, regulated and lubricated air at each station and a psi gauge the line crew can read at a glance.
Conditioning the air for conveyor stopper, pusher and lift cylinders on a beverage bottling line, where the differential-pressure drain keeps condensate off the bowls during continuous shifts and the lubricator mists the actuator seals.
Supplying low-pressure actuated valves and sample-handling cylinders on a chemical pilot-plant skid, where the low-pressure regulator type matches circuits that run well below standard main-line settings and the bracket gives tidy panel mounting.
Size 400 with a 1/2 in PT port sits in the middle-to-upper range of the GC family; step up to size 600 or down to 300 depending on the flow your line needs - and because AirTAC publishes flow as curves rather than one rated number, ask us to check the curve against your demand before you commit. The 40 um element is the standard grade for general plant air; choose the W variant only where finer particulate matters. Drain is differential-pressure here; automatic (A) and manual (M) variants exist if your duty or access suits them better. The round gauge is scaled in psi; square embedded gauges and MPa or bar scales are the other catalogue choices. PT is the standard thread, with G (BSPP) and NPT available to order, and the bracket is included. The low-pressure regulator type is the right pick for circuits running well below standard settings - confirm its exact adjustment range with us from the datasheet.
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 GC400 as performance curves rather than a single rated figure, so we do not quote one number. Tell us your working pressure and air demand and we will confirm the sizing from the datasheet curves on request before you order.
In the code GC400C15LC2, the blank drain position means the standard differential-pressure drain: the filter bowl bleeds condensate automatically as air flows through, with no manual draining in normal duty. The C2 suffix means an external round gauge fitted, scaled in psi; square embedded gauges and MPa or bar scales are the alternative catalogue options.
