The AirTAC GC400C15MLF2WG AirTAC F.R.L. Combination G1/2 5 um 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 GC series is AirTAC's three-piece F.R.L. combination: a separate air filter, pressure regulator and lubricator assembled as one air-treatment station. This GC400C15MLF2WG is built in size 400 with G1/2 (BSPP) ports, a 5 um filter element, a manual drain on the filter bowl, a low-pressure type regulator and an embedded square gauge reading in psi. The metal bowl on the filter section collects the water and particulate separated from the compressed air, and a mounting bracket is included so the set can be fixed to a machine frame or wall.
This is a genuine AirTAC part. The GC family is available in sizes 200, 300, 400 and 600, with port sizes from 1/8 to 1 inch, a choice of 40 um standard or 5 um (W) filtration, manual, automatic or differential-pressure drains, gauge scales in MPa, psi or bar, and PT, G or NPT threads. Rated flow is published as curves rather than a single figure, so ask us to confirm sizing and datasheet details for your application before ordering.

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.

A treatment point at a paint booth drop, where the 5 um element helps keep water and fine particulate out of the spray air, the regulator holds the booth's working pressure and the lubricator feeds a light oil mist to downstream equipment.
Feeding pneumatic cylinders and actuators on a carton-forming conveyor, with the regulator set to the line's working pressure, the square psi gauge giving operators a visible setpoint and the manual drain emptied during scheduled checks.
Supplying impact wrenches, grinders and other shop air tools from a header: the lubricator keeps tool motors oiled, the filter section removes water and chips of contamination, and the bracket mounts the set beside the manifold.
Size 400 with G1/2 ports sits in the upper-middle of the GC line; step up to size 600 or down to size 300 depending on the air your line needs - we will check the published flow curves with you rather than quote a single rated figure. The 5 um element (code W) suits applications needing finer particulate removal than the 40 um standard element. The M in the code is a manual drain: water in the filter bowl is released by opening the drain valve during routine checks, while automatic (A) and differential-pressure (blank) drain versions of the same size are available. The regulator here is the low-pressure type (code L); its exact adjustment range is not published, so confirm the setting you need with us. The embedded square gauge reads in psi, with MPa and bar scales as alternatives and an external round gauge optional. No reverse (check) valve is fitted on this code. Thread is G (BSPP); PT is the standard thread and NPT is an order option. A mounting bracket is included.
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 curves rather than a single rated figure, so we do not quote a number here. Tell us your line pressure and the air consumption of the equipment downstream, and we will confirm the correct size and the flow figures from the datasheet on request.
The M in the code specifies a manual drain: water collected in the filter bowl is released by opening the drain valve during routine checks. Automatic (A) and differential-pressure (blank) drain versions of the same size are available, and the 40 um standard element can be specified instead of this 5 um (W) grade at order time.
