The AirTAC GC30015ALF2W 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 PT1/2" ports, a 5 µm element, a automatic drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The AirTAC GC series is a three-piece F.R.L. combination: a separate air filter, a pressure regulator and an oil-mist lubricator assembled as one air-preparation set. This GC30015ALF2W is the size 300 unit with a 1/2 in PT port. The filter carries the fine 5 um element (code W) and an automatic drain, so collected water is expelled without manual attention. The regulator is the low-pressure type (code L) and is fitted with an embedded square gauge reading in psi; an external round gauge is available as an option. The filter and lubricator bowls are polycarbonate at this size, a mounting bracket is included, and no reverse/check valve is fitted. 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 family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and options including manual or differential-pressure drains, a 40 um standard or 5 um fine filter element, gauge scale in MPa, psi or bar, and G (BSPP) or NPT threads in place of the PT standard. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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. 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 tool-clamp and coolant-mist circuits on a machining centre, where the 5 um element protects fine valves from water and particulate and the lubricator mists oil to the air tools downstream.
Conditioning air for pick-and-place and carton-sealing cylinders on a packaging conveyor, with the automatic drain keeping condensate out of the valves during continuous shifts.
Serving spray-gun drops in a paint booth, where fine 5 um filtration, regulated low-pressure supply and controlled oil misting support consistent finish work.
Start with the size and port: this unit is size 300 with a 1/2 in PT port; step up to size 400 or 600, or down to 200, if your line's flow demand points elsewhere - and ask us to check the flow curves against your consumption before ordering, since AirTAC publishes flow as curves, not a single rating. The 5 um element (code W) suits finer air-quality needs; the 40 um standard element is the default choice where only coarse water and particulate removal is needed. The automatic drain is the low-maintenance option; manual and differential-pressure drains are also available in the family. The low-pressure regulator type (code L) is chosen where the circuit works below the standard regulator's range - the exact adjustment range is not published, so confirm it with us. The embedded square gauge here reads in psi; MPa or bar scales and an external round gauge can be specified. PT is the standard thread; G (BSPP) and NPT are catalogue options to order, and a mounting bracket is included.
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 the GC series as curves, not as a single rated figure, so we do not quote a number. Send us your application details and we will confirm the flow and sizing against the datasheet on request before you order.
The A in the code GC30015ALF2W specifies an automatic drain on the filter bowl, which expels collected condensate without manual intervention; M would be manual and blank would be differential-pressure. The L specifies the low-pressure regulator type, used where the circuit operates below the standard regulator's range - the exact adjustment range is not published, so confirm it with us on request.
