The AirTAC GC40015MLF2K 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 PT1/2" ports, a 40 µm element, a manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi).
The GC40015MLF2K is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one set. This size 400 unit is configured for 1/2 in PT ports, with a 40 um filter element and a manual drain on the filter bowl, a low-pressure type regulator fitted with an embedded square gauge scaled in psi, and a reverse/check valve in the regulator section. It treats compressed air in one pass: water and particulate are drained off, downstream pressure is held at the set point, and a fine oil mist is carried into the air line to lubricate downstream tools and actuators. A mounting bracket is included.
This is a genuine AirTAC part. The GC family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and with choices of drain type, filter grade (40 um standard, 5 um optional), gauge scale, thread (PT standard, G and NPT as order options) and reverse valve. Flow figures for this series are published as curves rather than a single rated number, so we confirm the datasheet and sizing for your application 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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.

Feeding filtered, regulated and lubricated air to the clamps, tool-changer cylinders and coolant-skirt actuators on a CNC machining centre, with the manual drain emptied during shift checks.
Conditioning the air that drives case-erectors, carton sealers and conveyor stop-gate cylinders on a packaging line, where the lubricator keeps cylinder seals running smoothly and the regulator holds a steady low set point.
Serving a bench drop on an assembly floor where air tools and pneumatic screwdrivers run all shift: water and dirt are caught in the 40 um filter, pressure is held at the station set point, and oil mist protects the tools.
Start with the port and size step: this unit is size 400 with 1/2 in PT ports; larger sizes carry larger ports and more flow, so match the size step to the air demand of the machine rather than the pipe alone. The regulator here is the low-pressure type, intended for circuits that run at reduced set points; if your line works near standard supply pressure, check with us which regulator type suits before ordering. Drain choice matters: this configuration has a manual drain, which needs periodic attention, while automatic and differential-pressure drains are available in the family. Filter grade is 40 um standard; the 5 um (W) element is the choice where finer particulate removal is needed. The gauge is the embedded square type scaled in psi; MPa or bar scales and an external round gauge are options. Thread is PT as standard, with G (BSPP) and NPT available to order, and a mounting bracket is included.
One honest note on sizing: AirTAC publishes flow for this series as curves, not as a single rated figure, so we do not quote a flow number here. Ask us to confirm the datasheet and check the sizing against your application before you order.
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 performance curves rather than a single rated figure, so we do not quote a flow number here. Contact us and we will confirm the datasheet and check the size 400 / 1/2 in configuration against your actual air demand before you order.
The M in the code GC40015MLF2K specifies a manual drain on the filter bowl: condensate is released by opening the drain by hand, which suits stations checked on a regular schedule. The family also offers an automatic drain (code A) and a differential-pressure drain (blank), which remove condensate without operator action - tell us your maintenance routine and we will confirm the right drain option.
