The AirTAC GC300C15MC2 AirTAC F.R.L. Combination, 1/2 in PT 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 See datasheet ports, a 40 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC300C15MC2 is a three-piece AirTAC G-series F.R.L. combination: a filter, a regulator and a lubricator assembled as one complete air-preparation set for compressed air. This size 300 unit is threaded PT1/2 (1/2 in, PT as the standard; G and NPT are order options), carries the standard 40 um filter element with a manual drain, and is fitted with an external round gauge scaled in psi. The regulator is the standard type with a setting range of 0.05-0.9 MPa (7-130 psi), the maximum inlet pressure is 1.0 MPa (145 psi), the working temperature range is -5 to 70 C (non-freezing), and a mounting bracket is included.
This is a genuine AirTAC part. The GC combination family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 in, and with real configuration choices: drain type (manual, automatic or differential-pressure), 40 um standard or 5 um (W) filtration, gauge style and scale (MPa, psi or bar), thread option and bracket. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet 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. Standard type, regulating 0.15 - 0.9 MPa (20 - 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-C1 filter, GR300-C1 regulator and GL300-C1 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 filtered, regulated and lubricated air to a CNC machining cell where the same supply serves pneumatic clamps, tool-change actuators and air-powered tool circuits on a 1/2 in main.
Conditioning the air feeding cylinder- and valve-driven stations on a packaging or bottling conveyor line, where water and particles are removed, pressure is held steady and actuators receive oil mist.
A wall-mounted supply point in a plant maintenance workshop, giving air tools and test rigs a single unit that cleans the air, sets working pressure on the psi gauge and lubricates downstream tools.
Start with the port step: this unit is size 300 with a 1/2 in PT port, so size up or down (200/400/600) if your line port or air demand calls for a different step - larger sizes carry larger ports and more flow capacity. Choose the drain to match maintenance practice: this configuration has a manual drain, which means someone drains the bowl on a routine; automatic or differential-pressure drain codes remove that task. The 40 um element is the standard grade; specify the W code for 5 um filtration where finer particle removal matters. The fitted gauge here is the external round type scaled in psi; embedded square gauges and MPa or bar scales are the other catalogue choices. PT is the standard thread, with G (BSPP) and NPT available to order, and the bracket is included.
One honest note on sizing: AirTAC publishes flow for this family as curves, not as a single rated number, so we do not quote a flow figure here. Send us your application details and we will confirm the sizing against the datasheet curves 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-C1 regulator with a GF300-C1 filter on that branch.
AirTAC publishes flow for the GC series as performance curves rather than a single rated figure, so we do not quote a flow number for this unit. Tell us your application - port size, line pressure and the equipment it supplies - and we will confirm the sizing from the datasheet curves on request before you order.
The M code in GC300C15MC2 specifies a manual drain on the filter bowl: accumulated water is released by operating the drain by hand as part of a routine check. If you would rather not rely on manual draining, the same size 300, 1/2 in unit is available with an automatic (A) or differential-pressure (blank) drain code instead.
