The AirTAC GC300C15LF2G AirTAC F.R.L. Combination G1/2 Low-Pressure 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 GC series is AirTAC's three-piece F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator built as one supply unit. This GC300C15LF2G serves 1/2 in (G1/2) pipework with the 40 um standard filter element on a differential-pressure drain, a low-pressure type regulator with an embedded square gauge reading in psi, and polycarbonate bowls at this size. It is rated for a maximum inlet pressure of 1.0 MPa (145 psi) and works from -5 to 70 C (non-freezing). A mounting bracket is included and no reverse/check valve is fitted.
This is a genuine AirTAC part, one configuration within a range spanning sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, a choice of differential-pressure, automatic or manual drains, 40 um or 5 um (W) filtration, gauge scales in MPa, psi or bar, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so ask us to confirm sizing and any datasheet figure 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.

Feeds clean, regulated and lubricated air to spray booths and air-powered applicators, where water and particulate in the supply would spoil finish quality.
Conditions the air feeding the pneumatic cylinders and air motors that index, clamp and divert bottles along a filling and packaging line.
Supplies filtered, pressure-controlled and oil-misted air to clamps, tool-changers and actuator circuits on a machining cell, keeping components protected and lubrication consistent.
Start with the size step: GC units come in 200, 300, 400 and 600, and this 300 size with its 1/2 in G-thread port should be matched against the flow your line actually needs. Because flow is published as curves, not a single rating, send us your demand and we will confirm the fit from the datasheet before you order. The regulator in this code is the low-pressure (L) type; if your process runs near standard shop pressure, the standard type may suit better, and we can confirm the adjustment range on request.
Other decodable choices: drain type (this unit uses the differential-pressure drain; automatic A or manual M are alternatives), filtration grade (40 um standard here, 5 um with code W), gauge scale (this one reads psi; MPa and bar are options), thread (PT is the standard; G and NPT are order options), and bracket inclusion.
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 curves rather than a single rated figure, so we do not quote a number here. Send us your working pressure and air demand and we will confirm the sizing against the datasheet on request.
This unit carries the differential-pressure drain, the default drainage method for the GC series. If you prefer a different approach, automatic (code A) and manual (code M) drains are orderable alternatives within the same series.
