The AirTAC GC30015MF2GK 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 GC30015MF2GK 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 your set pressure, and carries a fine oil mist to downstream equipment. This configuration is built on the GC300 size with G1/2 ports, uses the standard 40 um filter element, and has a manual drain on the filter bowl, so an operator opens the drain valve during routine checks rather than relying on an automatic mechanism. The regulator is the standard type with an adjustment range of 0.05-0.9 MPa (7-130 psi), an embedded square gauge with a psi scale is fitted so the set pressure is visible at the unit, and a reverse/check valve is included to hold downstream pressure if the supply drops. Maximum inlet pressure is 1.0 MPa (145 psi) and the operating temperature range is -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, manual or automatic or differential-pressure drains, a 5 um (W) filter grade option, gauge scale choices, and G or NPT thread variants in addition to the PT standard. Flow figures for this series are published as curves rather than a single rated number, so ask us to confirm the datasheet and sizing 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 0.05 - 0.9 MPa (7 - 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: 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 removes water and particles, the regulator holds a steady gun pressure, and the lubricator is set to zero or a light mist depending on the gun's requirements.
Supplying the pneumatic pushers, clampers and diverters on a carton-sealing conveyor, with one point where air is cleaned, pressure is set for the cylinders, and oil mist keeps seal-pack cylinders running smoothly.
Serving the air clamps and tool-holders on a CNC machining centre, where a check valve helps hold the clamped state if shop air dips, the gauge lets the setter verify clamp pressure in psi, and lubrication protects the clamping cylinders.
The main decodable choices are the size and port step, the drain type, the filter grade, the gauge and its scale, the thread, and whether a single unit or a combination suits the job. Size 300 with a 1/2 in port sits in the middle of the GC range; step up to 400 or 600 where the air demand is larger, or down to 200 for compact circuits, and match the flow requirement against the published curves before ordering. Manual drain (this unit, code M) suits installations where an operator can bleed the bowl on a routine; choose automatic or differential-pressure drain where the unit is hard to reach. The standard element is 40 um; specify the 5 um (W) grade where finer filtration is needed. The fitted square gauge here reads in psi; MPa and bar scales are available, and an external round gauge is optional. Thread: PT is the standard, while G (this unit) and NPT are catalogue options to order. A bracket is included for mounting.
Because flow for this series is published as curves and not as a single rated figure, ask us to confirm sizing against your application 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 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 honestly quote. Send us your air demand and line conditions and we will confirm the sizing and the datasheet figures for the GC300 at 1/2 in before you order.
Code M in GC30015MF2GK means the filter bowl is drained by hand, which suits stations an operator visits regularly. The GC family also offers automatic drain (code A) and differential-pressure drain (blank) for bowls that are not checked daily. All three drain types share the same 0.05-0.9 MPa (7-130 psi) regulation range on this standard-type unit.
