The AirTAC GC400C15MLC2GK AirTAC F.R.L. Combination Unit, G1/2 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 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, a pressure regulator and an oil-mist lubricator supplied together as one set. This configuration, GC400C15MLC2GK, is the 400 size with a G1/2 (BSPP) port. The filter carries the standard 40 um element with a manual drain, the regulator is the low-pressure type, a round gauge graduated in psi is fitted, and the set includes a reverse (check) valve and a mounting bracket.
This is a genuine AirTAC part. The GC line is published in 200, 300, 400 and 600 sizes covering ports from 1/8 in up to 1 in, with choices of thread (PT standard; G and NPT to order), drain type, filter grade (40 um standard, 5 um optional) and gauge scale. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Rated flow is published as curves rather than a single figure, so ask us to confirm sizing and datasheet values for your application.

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.

Conditions the supply to spray booths and air-assisted guns on a paint line, where the low-pressure regulator holds a gentle setting and the lubricator mists the air feeding downstream valves and actuators.
A combined filter, regulator and lubricator ahead of the cylinders and grippers on a carton-forming and sealing line, with the fitted check valve helping hold the circuit if the supply dips.
Prepares the air feeding clamps, tool-changers and coolant-mist valves in a machining cell; the 40 um element removes water and particulate before regulation and oil misting.
Choose the size by the port and flow step: 200, 300, 400 and 600 map to increasing ports from 1/8 in up to 1 in, so pick the size whose flow curve covers your demand rather than upsizing blindly. This unit is already fixed at 400 size, G1/2 port, G thread. The drain is manual here, so the bowl is emptied by hand on a schedule; automatic and differential-pressure drains are available elsewhere in the range. The filter grade is the standard 40 um; the W code gives 5 um where finer filtration is needed. The fitted round gauge reads in psi, with MPa and bar scales as alternatives, and the K code adds a reverse/check valve. Flow is published as curves, not a single rating, so send us your flow and pressure requirements and we will confirm this model against the datasheet 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-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 one number. Send us your line pressure and air demand and we will confirm the flow from the datasheet for this 400-size, G1/2 unit before you order.
The M code in GC400C15MLC2GK selects a manual drain on the filter bowl: collected water is released by hand, so plan a routine drain check as part of maintenance. Automatic and differential-pressure drain options are available in the GC range if you would rather not drain manually.
