The AirTAC GC30015G AirTAC F.R.L. Combination, G1/2 Port, 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 differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC30015G is a genuine AirTAC GC-series three-unit F.R.L. combination: a separate air filter, a pressure regulator and an oil-mist lubricator, assembled as one set for compressed-air preparation. This 300-size unit carries a G1/2 (BSPP) port, a 5 um filter element for finer water and particulate removal than the standard 40 um grade, and a differential-pressure drain that bleeds collected condensate automatically as the pressure differential across the bowl rises. The regulator is the low-pressure type, and a square pressure gauge with a psi scale is fitted so the set downstream pressure can be read directly at the unit. The bowls are polycarbonate, which keeps the condition of the air and the oil-mist level visible at a glance.
This is a genuine AirTAC part. The GC family is offered in sizes 200, 300, 400 and 600 with a choice of PT, G or NPT thread, 40 um standard or 5 um (W) filtration, automatic, manual or differential-pressure drains, standard or low-pressure regulation, and gauge or no-gauge configurations. Flow figures are published as curves rather than a single rating, so ask us to confirm the datasheet and sizing 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.

Feeding spray guns and air-assisted applicators at a finishing-station air drop, where the 5 um element, regulated low-pressure supply and oil misting keep the tools fed with conditioned air.
Conditioning the air feeding conveyor stopper and clamp cylinders on a packaging line, with the regulator set to the circuit's working pressure and the lubricator misting the cylinder and valve seals.
Supplying filtered, regulated and lubricated air to pneumatic clamps and workholding fixtures on a machining cell, with the psi gauge giving the operator a direct read of set pressure.
Start with the port and size: this unit is size 300 with a G1/2 thread, one step up from 1/4 and 3/8 sizes in the range, so match it to your line size and required air delivery. The 5 um (W) element suits applications that need finer particulate and water removal than the standard 40 um grade; the drain here is differential-pressure, with automatic and manual drains available elsewhere in the family if your maintenance routine prefers them. The low-pressure regulator is intended for circuits that work below standard regulation ranges - confirm the exact range with us before ordering. The fitted square gauge reads in psi; MPa and bar scales, an external round gauge, a no-gauge build, and PT or NPT threads are the other decodable choices. Because flow is published as curves rather than a single rated figure, send us your application details and we will confirm the sizing against the datasheet 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 GR300-15 regulator with a GF300-15 filter on that branch.
AirTAC publishes flow for this series as curves, not as a single rated figure, so we do not quote a flow number. Send us your line size, working pressure and air demand and we will confirm the flow and sizing from the datasheet on request.
The W code in GC30015LF2WG selects the 5 um filter element instead of the standard 40 um grade, for finer water and particulate removal. The L code selects the low-pressure regulator type, intended for circuits working below standard regulation ranges; its exact range is not published, so confirm it with us before ordering.
