The AirTAC GC30015MLC2W AirTAC F.R.L. Combination, PT1/2, 5 um 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 5 µm element, a manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi).
The AirTAC GC30015MLC2W is a three-piece F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator, giving one half-inch supply point that removes water and particulate down to 5 um, holds a set downstream pressure and carries oil mist to downstream air tools and cylinders. This 300-size unit is threaded PT1/2 (1/2 in), uses the fine 5 um filter element (code W), drains the filter bowl by hand with the manual drain, and is the low-pressure regulator type. It comes with a round pressure gauge reading in psi, and the mounting bracket is included. The filter and lubricator bowls are polycarbonate (PC). Maximum working (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 combination is offered in sizes 200, 300, 400 and 600 with a choice of ports, drain types, filter grades (40 um standard, 5 um optional), gauge styles and scales, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing figures for your application before ordering.

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.

Feeds filtered, regulated and lubricated air to the clamps, fixtures and tool-changer cylinders on a machining centre supplied from a half-inch drop, with the 5 um element protecting fine pilot valves.
Sits at the head of a half-inch assembly-station supply, conditioning air before it reaches impact wrenches, air ratchets and seating cylinders so each station gets clean, regulated, oil-misted air.
Conditions the air feeding the cylinders and vacuum generators on carton-erecting and case-sealing conveyors, where the regulator holds a steady set pressure and the lubricator keeps actuation cylinders running smoothly.
Size and port set the flow path: this unit is 300 size with a PT1/2 (1/2 in) port, so match it to a half-inch air line and check the flow curve against your demand rather than assuming a rating - we will confirm the curve for your flow on request. The regulator here is the low-pressure type, so if your set point is low, confirm the adjustment range with us before ordering. Drain choice matters: manual drain (this unit) means an operator drains the bowl by hand, while automatic and differential-pressure drains are available on other codes if you cannot schedule drain rounds. The filter grade is 5 um (code W); the standard element is 40 um if finer filtration is not needed. The gauge fitted is the external round type reading in psi; embedded square gauges and MPa or bar scales are the other catalogue choices. Thread is PT as standard - G (BSPP) and NPT are orderable options, not a delivery matter. Bracket included on this code.
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 l/min, m3/h or SCFM figure. Tell us your line pressure and the flow your application needs, and we will confirm against the datasheet curve whether this 300-size, PT1/2 unit is correctly sized before you order.
The M in the code selects the manual drain: collected water is released by opening the drain by hand, so someone needs to check the bowl as part of routine rounds. If that does not suit the installation, GC codes with automatic or differential-pressure drains are available - the drain choice is a real ordering decision, not an accessory you can swap later.
