The AirTAC GC40015MLC2GK AirTAC F.R.L. Combination G1/2 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 PT1/2" ports, a 40 µm element, a manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi).
The GC40015MLC2GK is an AirTAC GC-series three-unit F.R.L. combination: a separate filter, regulator and lubricator assembled as one set, so compressed air is cleaned of water and particulate, held at a set working pressure, and carry oil mist to downstream pneumatic components. This configuration is built for 1/2 in ports with G (BSPP) thread, carries the standard 40 um filter element, and uses a manual drain on the filter bowl, so an operator opens the drain as part of routine checks rather than relying on an automatic or differential-pressure drain. It is a low-pressure type regulator fitted with a round gauge scaled in psi, a reverse (check) valve to hold downstream pressure when supply is lost, and a mounting bracket is included.
This is a genuine AirTAC part. The GC family is published in 200, 300, 400 and 600 sizes with a choice of ports and threads (PT standard; G and NPT as catalogue options), drain types, 40 um or 5 um (W) filter grades, gauge styles and scales, and reverse-valve or low-pressure variants. Flow for this size is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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. 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.

|---|---|
| 15 | Port size PT1/2". This body offers 10 = PT3/8", 15 = PT1/2". |
| M | Drain: Manual drain — this also sets the regulating band (0.05 - 0.9 MPa (7 - 130 psi)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| G | G (BSPP) thread. PT is the default; G is BSPP and T is NPT. |
| K | Reverse-flow (reflux) valve fitted. |
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 impact drivers, nut runners and clamping fixtures at assembly stations, where one 1/2 in drop needs filtered, regulated and lubricated air for a bank of air tools.
Supplying the extend-and-retract cylinders, grippers and stopper gates along a packaging conveyor, where the check valve holds the set pressure if the plant supply dips.
A workshop bench rig where technicians set a stable low working pressure by the psi gauge for leak testing and actuator function checks, with manual draining built into the shift routine.
Start with the size and port: the 400 size with a 1/2 in connection suits lines whose flow demand sits in that band, and stepping up or down a size changes both the port and the flow capacity, which we can confirm against the published curves before you order. Real decodable choices for this unit are: drain type (manual here, with automatic and differential-pressure available in the family), filter grade (40 um standard, 5 um with the W code), gauge style and scale (this build has a round gauge in psi; an embedded square gauge in MPa, psi or bar is the standard route), thread (PT is the standard; G and NPT are order options), and the low-pressure regulator type with the reverse/check valve fitted.
Be aware that the low-pressure type's exact regulation range is not published in the material we hold, and flow is published as curves, not a single rating. Send us your line pressure and demand and we will confirm the datasheet figures and sizing 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 curves, not as a single rated figure, so we do not quote a number. Tell us your line pressure and air demand and we will confirm the relevant datasheet curve and check the 400 size against your application before you order.
The M in the code sets a manual drain: an operator opens the filter bowl drain during routine checks, instead of the automatic or differential-pressure drain options available in the family. The L code sets the low-pressure regulator type; its exact regulation range is not published in our material, so we confirm it from the datasheet on request.
