The AirTAC GC30015MLC2GK AirTAC F.R.L. Combination, 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 PT1/2" ports, a 40 µm element, a manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi).
The GC30015MLC2GK 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 for compressed-air lines. This configuration is built for a G1/2 (BSPP) port on the 300 size, with a 40 um standard filter element, a manual drain on the filter bowl, a low-pressure type regulator, a round external gauge reading in psi, a reverse/check valve fitted, and a mounting bracket included. The bowls are polycarbonate (PC), and the unit handles a maximum inlet pressure of 1.0 MPa (145 psi) at temperatures from -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GC family is available in sizes 200, 300, 400 and 600, with port options, drain types, filter grades, gauge styles and scales to suit the line. Because flow is published as curves rather than a single rating, we 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 08 = PT1/4", 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) | 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. |

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: GF300-15 filter, GR300-15 regulator and GL300-15 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.

Feeds filtered, regulated and lubricated air to the pneumatic clamps and tool-change cylinders on a CNC machining cell, with the psi gauge letting operators set and monitor clamp pressure at the machine.
Conditions the air feeding spray guns and air-assisted applicators in an automotive paint booth, removing water and particulate, holding a steady low-pressure setting, and carrying oil mist to keep gun air motors running smoothly.
Supplies treated air to the cylinders and air motors on a carton-sealing and case-packing conveyor line, with the check valve holding the set circuit against backflow and the manual drain supporting a supervised daily maintenance routine.
Start with the port step: the 300 size carries the 1/2 in port here, and moving up or down a size changes both the port and the flow capacity, so match the size to the air demand of the circuit. For the filter, 40 um is the standard element and 5 um (code W) is the finer option where downstream equipment needs cleaner air. The drain on this unit is manual, meaning someone bleeds the bowl periodically; automatic and differential-pressure drains are available on other configurations if unattended drainage matters. The gauge here is the external round type reading in psi, with MPa and bar scales offered as alternatives, and the thread is G (BSPP) while PT is the standard and NPT can be ordered. A reverse/check valve is fitted on this unit and the mounting bracket is included.
Flow for this family is published as curves, not a single rated figure, so ask us to confirm sizing against your application before ordering.
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 GR300-15 regulator with a GF300-15 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. Tell us your line pressure and the air demand of the equipment, and we will confirm the sizing from the datasheet on request before you order.
The M in the code GC30015MLC2GK specifies a manual drain on the filter bowl, so accumulated water is bled off by hand at intervals you set. If you prefer unattended drainage, the same GC configurations are available with an automatic drain (code A) or the default differential-pressure drain.
