The AirTAC GC30015MLF2G AirTAC GC F.R.L. Combination G1/2 Manual Drain 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 GC30015MLF2G is an AirTAC GC three-piece F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one air-treatment set for compressed-air lines. This configuration is built for G1/2 (1/2 in) ports with G thread, carries a 40 um standard filter grade, and uses a manual drain on the filter bowl, so an operator or maintenance routine drains collected water on a schedule. The regulator is the low-pressure type and is fitted with an embedded square gauge scaled in psi, giving a direct local reading of downstream pressure while the lubricator feeds oil mist to downstream tools and actuators.
This is a genuine AirTAC part in the GC series, which spans sizes 200, 300, 400 and 600 with port options from 1/8 in to 1 in, thread options PT (standard), G and NPT, drain choices, filter grades and gauge scales. Flow is published 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.

A filtered, regulated and lubricated supply point feeding spray guns and air-assisted applicators on a paint line, where clean, moisture-drained air at a stable low pressure and a light oil mist keep finish quality consistent.
A single F.R.L. set at the machine inlet conditioning shop air for pneumatic tool changers, clamps and air-powered spindles, with the psi gauge letting operators verify set pressure at a glance and the manual drain emptied during shift checks.
Conditioning air for carton sealers, case packers and conveyor diverters on a packaging line, where the three separate filter, regulator and lubricator stages protect cylinders and valves and keep downstream motion smooth.
Size and port are the first decodable choice: this unit is size 300 with a 1/2 in port, so step up to size 400 or 600 for larger lines and higher flow demand, or down to size 200 for compact circuits. Because flow is published as curves and not a single rating, ask us to confirm sizing against your application before ordering. Other real choices on this family: drain type (this unit is manual; automatic and differential-pressure drains exist on other codes), filter grade (40 um standard here, 5 um with code W), gauge scale (this unit is a square gauge in psi; MPa and bar scales and an external round gauge are options), and thread (G here; PT is the standard thread and NPT is also a catalogue option). The low-pressure regulator type is the right pick where the circuit works below the standard regulator range; the exact range for this low-pressure type is not published, so confirm it with us.
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 this series as curves rather than a single rated figure, so there is no one rated flow number we can quote. Tell us your line pressure and the air demand of your equipment and we will confirm the sizing against the datasheet curves on request before you order.
A GFR combines filtration and regulation in one body but does not lubricate. This GC set adds a separate oil-mist lubricator, so it suits circuits with pneumatic cylinders, air tools or valves that need a continuous oil feed. If your downstream equipment is oil-free by design, a GFR or GF unit is the better decode; this manual-drain, 40 um, low-pressure GC with a psi gauge is the choice when all three functions are needed.
