The AirTAC GC400C15F2K AirTAC F.R.L. Combination, PT1/2 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 GC400C15F2K is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one supply package. This 400-size unit is ported PT1/2 and carries the standard 40 um filter element with a differential-pressure drain on the filter bowl, so collected water is expelled automatically as the pressure differential across the drain rises - no daily manual draining on a busy line. The regulator is the standard type with a 0.15-0.9 MPa (20-130 psi) adjustment range, read on the fitted embedded square gauge scaled in psi, and a reverse/check valve is fitted so downstream pressure is held if the upstream supply is lost. For size 400 the filter bowl is PC (polycarbonate); the bowl is aluminium alloy only at size 600.
This is a genuine AirTAC part. The GC family is available in sizes 200, 300, 400 and 600, with port options from 1/8 to 1 inch, G or NPT thread variants, automatic, manual or differential-pressure drains, a 5 um (code W) filter element, gauge scales in MPa, psi or bar, and round-gauge or no-gauge options. Rated flow for this combination is published as curves rather than a single figure - ask us and we will confirm the datasheet figures against your application.

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.

On a bottling or canning line, pusher and stopper cylinders along the conveyor run continuously off a 1/2 inch ring main. This unit filters water and scale from the supply, holds a set working pressure at the actuators, and meters oil mist so cylinder seals and valves last through long production shifts.
At an automotive assembly plant, impact wrenches and nutrunners at a workstation take their air from a 1/2 inch drop. Clean, regulated, lubricated air keeps tools running at a consistent torque and protects the vane motors, while the check valve holds downstream pressure if the main is isolated.
On a CNC machining cell with pneumatic workholding clamps, a stable supply pressure is critical to clamp force repeatability. This three-unit package on the cell's 1/2 inch supply removes condensate and chips-carrying particulate, regulates the clamp circuit pressure read in psi, and lubricates the clamp cylinders.
Size and port are the first choice: step up from 200 through 600 as your port size and air demand grow - this unit is the 400 size with a 1/2 inch PT port. Drain type is a real decision on the filter: differential-pressure (this unit) drains automatically as the element loads, automatic (code A) drains on a level or timer principle, and manual (code M) needs someone to open the drain. Filter grade is 40 um standard or 5 um with code W if downstream equipment needs finer particulate removal. The gauge here is the embedded square type scaled in psi; MPa and bar scales and an external round gauge are order options. Thread is PT as standard, with G (BSPP) and NPT as catalogue options to order, and a reverse/check valve (code K) is fitted on this unit. Flow 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 performance curves rather than a single rated figure, so we do not quote one number. Tell us your line pressure and the air demand of your equipment and we will confirm the datasheet flow curves for this 400-size, PT1/2 unit against your application before you order.
K is the reverse (check) valve option: a valve is fitted that holds downstream pressure if the upstream supply is lost or the unit is isolated. On circuits such as pneumatic clamping this keeps the set pressure at the actuators instead of letting it bleed back. Units without the K code have no check valve fitted.
