The AirTAC GC300C15MLC2WGK AirTAC F.R.L. Combination G1/2 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 See datasheet ports, a 40 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The AirTAC GC300C15MLC2WGK is a three-piece F.R.L. combination: a separate air filter, a pressure regulator and an oil-mist lubricator, assembled as one set for a G1/2 (1/2 in) line. This configuration carries a 5 um filter element (code W) with a manual drain on the filter bowl, a low-pressure type regulator, a round pressure gauge reading in psi, a reverse/check valve (code K), an included mounting bracket, and a metal bowl on the filter section. Together the three stages remove water and particulate from the compressed air, hold a stable downstream pressure, and add a controlled oil mist for downstream air tools and cylinders.
This is a genuine AirTAC part from the GC series, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in up to 1 in, a choice of drain types, 40 um standard or 5 um fine filtration, gauge style and scale options, PT standard thread with G and NPT as order options, and reverse/check valve variants. Flow is published in the AirTAC catalogue 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. 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 clean, regulated and lubricated air to the clamping fixtures, tool-change cylinders and air-driven actuators on a CNC machining centre, where the 5 um element protects fine valve spools and the lubricator keeps cylinders running smoothly.
Supplying the pneumatic cylinders that drive carton forming, sealing and pusher stations on a packaging conveyor line, with the regulator holding a steady working pressure and the reverse/check valve helping hold downstream conditions.
Serving as the point-of-use treatment set on a compressed-air drop in an assembly plant, conditioning air before it reaches air wrenches, impact drivers and other shop-air tools that rely on an oil mist for daily service life.
Start with the size and port: the 300 size with a 1/2 in port sits mid-range in the GC series, and the right step depends on the air demand of the line it feeds - ask us to check the published flow curves against your consumption before ordering, since AirTAC publishes flow as curves, not a single rating. This unit is already configured with the 5 um element rather than the 40 um standard, a manual drain, a low-pressure regulator, a round psi gauge and a reverse/check valve, so if your application needs automatic or differential-pressure draining, a different gauge scale (MPa, psi or bar), or a coarser element, those are decodable alternatives within the series. Thread is G (BSPP) here; PT is the catalogue standard and NPT is an order option. A mounting bracket is included. If you only need filtration plus regulation without lubrication, the GFR two-function family covers that instead of the full three-unit set.
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 rated flow number. Send us your line pressure and air consumption and we will confirm the flow figures from the datasheet for this exact 300-size, 1/2 in configuration on request.
The M in the code gives the filter section a manual drain: accumulated condensate must be drained by hand rather than automatically. The GC series also offers automatic and differential-pressure drain variants, so if nobody is on site to drain the bowl regularly, ask us about the A-coded alternative for this size.
