The AirTAC GC40015F2K AirTAC F.R.L. Unit, PT1/2, 3-Piece 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 PT1/2" ports, a 40 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The AirTAC GC40015F2K is a three-piece F.R.L. combination: a separate filter, regulator and lubricator assembled as one air-preparation set. This size 400 unit is fitted with a 1/2 in PT port, a 40 um filter element with a differential-pressure drain bowl in polycarbonate, a standard regulator adjustable from 0.15 to 0.9 MPa (20-130 psi), and an embedded square gauge scaled in psi. A reverse/check valve is fitted, and the set includes a mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GC series is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and with options including automatic or manual drains, a 5 um filter element (code W), alternative gauge scales, G or NPT threads, and low-pressure regulation. Flow is published as curves rather than a single rated figure, so we confirm flow and datasheet details 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: GF400-15 filter, GR400-15 regulator and GL400-15 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 clean, regulated, lubricated air to a carton-forming and sealing line, where the filter removes water and particulate, the regulator holds a steady working pressure and the lubricator mists oil to the line's actuators.
Supplies the pneumatic cylinders that index and stop a conveyor system, keeping moisture and debris out of the valves while the check valve holds downstream pressure if the supply dips.
Prepares supply air for clamps, tool-changers and work-holding fixtures on a machining cell, with the psi-scaled gauge giving operators a direct read of set pressure at the machine.
Size 400 with a 1/2 in PT port sits in the middle of the GC range; step up to size 600 or down to 300/200 according to the flow your line needs, since larger sizes carry larger ports and more flow. The 40 um element is the standard grade; choose the 5 um W option where downstream equipment needs finer filtration. Drain choice matters: this unit uses the differential-pressure drain (default), but automatic or manual drains can be ordered. The fitted square gauge is scaled in psi; MPa or bar scales and an external round gauge are alternatives. PT is the standard thread, with G (BSPP) and NPT available as order options, and a bracket is included. Because flow is published as curves rather than a single rating, 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 GR400-15 regulator with a GF400-15 filter on that branch.
AirTAC publishes flow for the GC series as curves, not as a single rated figure, so we do not quote a number here. Tell us your application and we will confirm the flow and datasheet figures for this unit on request before you order.
The blank drain position in the code means the differential-pressure drain, the default for the GC series, which bleeds condensate as flow pressure differences build. If you prefer hands-off operation or manual control, the same size 400 set can be ordered with an automatic (code A) or manual (code M) drain.
