The AirTAC GC400C15MLF2 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).
The AirTAC GC400C15MLF2 is a three-piece F.R.L. combination: a separate air filter, a pressure regulator and an oil-mist lubricator, assembled as one coordinated set for compressed-air preparation. This size 400 unit is built for 1/2 in PT ports (PT is the standard thread; G and NPT are order options). The filter element is the standard 40 um grade for water and particulate removal, the bowl is drained manually, and the regulator is the low-pressure type with an embedded square gauge reading in psi. A mounting bracket is included, and the polycarbonate bowl on this size keeps the condensate visible (only size 600 uses an aluminium alloy bowl).
This is a genuine AirTAC part. The GC family spans sizes 200, 300, 400 and 600, with port options from 1/8 in to 1 in, manual, automatic or differential-pressure drains, a 5 um filter element option, gauge scale choices and G/NPT thread variants. Rated flow is published as curves rather than a single figure, so ask us and we will confirm the datasheet figures 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. 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.

Feeds clean, regulated and lubricated air to the tool-clamp and pallet-change circuits of a CNC machining centre, with the 40 um element catching pipe scale and the lubricator misting the way for air cylinders on the tool changer.
Sits at the drop of a carton-sealing machine on a packaging conveyor, conditioning the air that drives the flap-fold and taping cylinders so seals stay consistent through a full shift.
Installed at the air drop serving a paint-shop workstation, where the filter strips water and debris ahead of the regulator setting the line pressure for spray equipment and the lubricator feeding air tools.
Start with the port step: this unit is the size 400 body on 1/2 in PT ports; step up or down through sizes 200/300/400/600 to match the line size and the flow your circuit needs. Choose the drain next: manual (as coded here) means an operator drains the bowl, while automatic and differential-pressure drains are available on the same family. The filter grade is the standard 40 um; specify W for the 5 um element where finer particulate removal is required. The gauge here is the embedded square type on a psi scale, with MPa or bar scales and an external round gauge available as options. Thread is PT as standard, with G (BSPP) and NPT as order options, and the bracket is included.
One honest note before you order: AirTAC publishes filter flow as curves, not as a single rated number, and the exact set-pressure range of the low-pressure regulator type is not listed as a single figure either. Send us your line size, upstream pressure and target setting, and we will confirm the sizing and the datasheet figures against your application before you commit.
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 filter and regulator flow as performance curves rather than a single rated figure, so we do not quote one number here. Tell us your line size, upstream pressure and the flow your circuit needs, and we will confirm the datasheet curve figures for this exact configuration on request before you order.
The L in the code marks the low-pressure regulator type, intended for circuits where the working setting sits below the standard range; the exact setting range is not published as a single figure, so we confirm it from the datasheet on request. The M marks a manual drain: an operator opens the drain at the filter bowl to remove collected condensate, instead of the automatic or differential-pressure drain options available in the same family.
