The AirTAC GC30015MLC2G 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 GC30015MLC2G is a genuine AirTAC three-piece F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one GC300 unit. It cleans compressed air of water and particulate down to the standard 40 um grade, regulates downstream pressure, and adds lubricating oil mist for air-powered tools and actuators. This configuration is built around a G1/2 (BSPP) port on the size-300 body, uses a manual drain on the filter bowl, and is the low-pressure regulator type. A round gauge with a psi scale is fitted so operators can read and set the regulated pressure directly, and the mounting bracket is included for solid panel or frame installation.
This is a genuine AirTAC part. The GC family is offered in sizes 200, 300, 400 and 600 with port sizes stepping from 1/8 in up to 1 in, and with choices of drain type, filter grade (40 um standard, 5 um optional), gauge style and scale, thread form (PT standard; G and NPT as order options) and reverse/check valve. Flow is published by AirTAC as curves rather than a single rated figure, so we confirm the datasheet and flow 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.

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.

Feeding spray guns and air-assisted applicators on a paint line, where the filter strips water and pipe scale, the lubricator mists oil to the gun's air motor, and the low-pressure regulator holds a gentle, repeatable supply pressure at the booth.
Conditioning the shop-air feed into a CNC cell: clean, dry-ish air to the tool changer and clamps, regulated pressure read locally on the psi gauge, and oil mist carried to air cylinders and pneumatic fixtures downstream.
Mounted on the bracket at the air inlet of a cartoning or wrapping machine, giving the machine's valve manifold filtered, lubricated air at a set pressure, with the manual drain emptied during scheduled changeover and maintenance rounds.
Start with the port step: this unit is size 300 with a G1/2 port, one of the mid sizes in the 200/300/400/600 range - step up or down a size if your line's port standard or demanded air volume differs, and ask us to confirm sizing against the published flow curves before ordering. The manual drain here means an operator or maintenance round opens the drain to expel collected water, which suits stations that are already visited regularly; an automatic or differential-pressure drain variant removes that task if the unit will sit unattended. The 40 um grade is the standard element for general plant air; specify the W code if you need the 5 um element. The fitted round gauge reads in psi; square embedded gauges and MPa or bar scales are the alternative. Thread is G (BSPP) on this unit - PT is the catalogue standard and NPT is orderable, so match your piping. The bracket is included. The regulator is the low-pressure type; its exact adjustment range is not published in our sheet, so confirm it with us if your setpoint is near the bottom or top of a standard range.
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, not as a single rated number, so we do not quote a rated flow, Cv or l/min figure for this unit. Tell us your line pressure and the air demand of the equipment it will feed, and we will confirm the sizing against the datasheet curves on request before you order.
The M in the code selects a manual drain on the filter bowl: collected water is expelled by opening the drain during maintenance rounds, unlike the automatic or differential-pressure drain options that discharge on their own. The L code makes this the low-pressure regulator variant, intended for lower setpoints than the standard type; its exact adjustment range is not published in our sheet, so confirm it with us if your setpoint is critical.
