The AirTAC GC400C15LF2K 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).
GC400C15LF2K is an AirTAC GC-series three-unit F.R.L. combination: a separate filter, regulator and lubricator assembled into one air-preparation set. This size GC400 unit is ported PT1/2 (G and NPT threads are order options), carries the standard 40 um filter element with a differential-pressure drain, and is built on the low-pressure type regulator with an embedded square gauge scaled in psi. A reverse/check valve is fitted and a mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi), the working temperature range is -5 to 70 C non-freezing, and the bowls on this 400 size are polycarbonate.
This is a genuine AirTAC part. The GC combination is offered in sizes 200, 300, 400 and 600, with a choice of drain type, 40 um or 5 um (W) filtration, gauge scale, thread and reverse valve, so a set can be matched to the line it feeds. Flow is published as curves rather than a single rating, so ask us to confirm sizing and datasheet figures 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.

Installed at a plant-air drop feeding an assembly line, this set filters water and particulate from the compressed air, holds the line pressure the station needs and adds oil mist for the cylinders, grippers and air tools downstream - one preparation point for a whole work cell.
On a machining cell where fixtures and clamps are actuated by air cylinders, this combination cleans the supply, regulates it to the clamp circuit's set pressure and lubricates the sealing surfaces, with the check valve holding the circuit if the upstream supply dips.
Packaging machines and conveyor diverters running air cylinders benefit from a single set that removes condensate and debris, keeps the operating pressure steady for repeatable strokes and mists the cylinders - the lubricator being the reason to choose a three-unit set over a filter-regulator alone.
The real choices in this series are decodable from the code. Step the size (200/300/400/600) and the port that follows it against the flow your line needs; choose the drain type - differential-pressure (this unit), automatic (A) or manual (M); pick the filtration grade, 40 um standard or 5 um with W; set the gauge scale (MPa, psi or bar); select the thread, PT as standard here with G and NPT as order options; and add K if a reverse/check valve is wanted. This unit is the low-pressure type (L), so its regulator adjustment range differs from the standard type and is not published in the material we hold - we confirm it on request. Because flow is published as curves rather than a single rated figure, ask us to check the curve data 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 this series as curves, not as a single rated figure, so we do not quote a number here. Send us your line pressure, the port size you plan to use and the air consumption of the equipment you are feeding, and we will confirm the flow against the datasheet curves before you order.
The L code sets the regulator to the low-pressure type instead of the standard type. Its exact adjustment range is not published in the material we hold, so we confirm it against your required set pressure on request. Everything else in the code decodes normally: PT1/2 ports, 40 um filter element with differential-pressure drain, square gauge scaled in psi, reverse/check valve fitted and mounting bracket included.
