The AirTAC GC300C15LC2W 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 See datasheet ports, a 40 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC300C15LC2W is an AirTAC GC three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one supply unit. This configuration is size 300 with a PT1/2 port, a differential-pressure drain on the filter bowl, and a 5 um filter element (the fine-grade option instead of the standard 40 um). The regulator is the low-pressure type and carries a round gauge reading in psi, and the lubricator feeds oil mist downstream to protect air tools and cylinders. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GC series is available in sizes 200, 300, 400 and 600 with a choice of ports, threads (PT standard, G and NPT to order), drain types, filter grades, gauge styles and scales, so a matching unit can be built for most compressed-air supply points. Flow is published as curves rather than a single rating, so ask us to confirm sizing and 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.

Feeds filtered, regulated and lubricated air to the clamps, chucks and blow-off circuits of a CNC lathe or machining centre, with the 5 um element protecting fine pilot valves from particulate carry-over.
Supplies the cylinders and diverters that push, stop and sort packs on a bottling or carton conveyor line, where the lubricator keeps seal wear down through continuous shift running.
Serves drop lines at assembly benches running impact drivers, nut runners and air ratchets, giving each station clean, pressure-controlled and oil-misted air at a 1/2 in supply connection.
Start with size and port: the 300 size with its PT1/2 port suits lines supplied at 1/2 in, and larger sizes carry larger ports and more flow - step up if your demand sits near the top of a size's curve. Choose the drain to match attendance: differential-pressure drain (fitted here) discharges automatically as flow passes, automatic (A) drains continuously, and manual (M) needs someone to open the bowl. This unit carries the 5 um element (code W); choose it where finer particulate removal matters, or the standard 40 um where coarser protection is enough. The round psi gauge is fitted here; embedded square gauges and MPa or bar scales are the other options. Thread is PT as standard - order G (BSPP) or NPT if your pipework needs it - and the mounting bracket is included.
One honest note: AirTAC publishes flow as curves, not a single rated figure, and the exact regulation range of the low-pressure type is not stated in our data. Ask us to confirm both 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-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 one number. Send us your working pressure and air demand and we will confirm the sizing from the datasheet curves before you order.
The L code in GC300C15LC2W marks the low-pressure regulator variant, intended for applications set below the standard regulator's normal range. The exact adjustment range for this variant is not published in our data, so we will confirm it on request. The unit also carries the 5 um filter element (code W) instead of the standard 40 um, and the differential-pressure drain discharges collected water automatically as air flows through.
