The AirTAC GC40015AF2K AirTAC F.R.L. Combination, PT1/2, Auto Drain 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 automatic drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC40015AF2K is a three-unit F.R.L. combination from AirTAC: a separate air filter, pressure regulator and oil-mist lubricator assembled as one filter-regulate-lubricate station. This size 400 unit is built around 1/2 in PT ports (PT is the standard thread; G and NPT are order options). The filter section carries the standard 40 um element and an automatic drain that expels collected condensate without manual attention, and both bowls are polycarbonate. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), an embedded square gauge scaled in psi, and a reverse/check valve fitted to hold downstream settings. 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 family is published in sizes 200, 300, 400 and 600, with port options from 1/8 to 1 in, a choice of differential-pressure, automatic or manual drain, a 5 um filter element option (code W), gauge scales in MPa, psi or bar, and G or NPT threads. Flow for this series is published as curves rather than a single rated figure, so we confirm flow and datasheet figures on request before you order.

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 filtered, regulated and lubricated air to impact wrenches and nutrunners at assembly stations, with the automatic drain handling condensate on lines that run across shifts.
Prepares shop air for pneumatic clamps, tool-change cylinders and chip-conveyors on a machining centre, with the check valve holding the set pressure if the main supply dips.
Conditions air for case-erectors, sealing jaws and conveyor diverters on a carton-packing line, where the lubricator keeps cylinder seals working through continuous duty.
Size 400 with 1/2 in PT ports sits in the upper-middle of the GC range; step up to size 600 or down to 300 depending on the flow your line needs, and match the port to your piping thread (PT standard, G or NPT to order). Choose the drain to suit access: automatic here suits installations that are not checked daily, manual suits attended stations, and differential-pressure drain is the default where a pressure drop signal is acceptable. The 40 um element is the standard grade; specify the 5 um W option if downstream valves or instruments need finer filtration. The fitted square gauge is scaled in psi; MPa and bar scales and an external round gauge are alternatives. A reverse/check valve (fitted on this unit) holds the regulated setting if upstream supply is lost. A mounting 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 working pressure and the air demand of the equipment you are feeding, and we will confirm the correct size from the datasheet on request before you order.
This unit carries code A, the automatic drain, which expels collected condensate from the filter bowl on its own - useful for installations that are not checked every day. The manual drain (code M) discharges only when operated by hand, and the differential-pressure drain (blank) is the catalogue default. All three are order choices across the GC family.
