The AirTAC GC30015ALF2 AirTAC F.R.L. Combination PT1/2 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 PT1/2" ports, a 40 µm element, a automatic drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The AirTAC GC30015ALF2 is a three-piece F.R.L. combination that conditions compressed air in one assembly: a filter that removes water and particulate, a regulator that sets working pressure, and a lubricator that feeds an oil mist downstream to pneumatic tools and cylinders. This 300-size unit is built for 1/2 in PT ports. The filter element is the 40 um standard grade, the bowl drains automatically, and the regulator is the low-pressure type for lines that run below standard working pressures. A square pressure gauge scaled in psi is fitted, and a mounting bracket is included.
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, plus choices of drain type, 5 um filtration (code W), gauge scale, thread form (PT standard, G and NPT to order) and reverse/check valve. Flow is published as curves rather than a single rating, so ask us to confirm sizing and any datasheet figure against 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.

At a 1/2 in PT drop feeding spray guns and air-assisted applicators, the filter removes water and 40 um particulate, the low-pressure regulator holds a gentle set pressure, and the lubricator mists oil to keep gun triggers and air motors running smoothly.
On a carton-forming and sealing conveyor fed at 1/2 in, the combination keeps the air clean and dry for valve and cylinder internals, regulates pressure for consistent stroke force, and lubricates the actuation circuit to extend seal life.
For a CNC workholding circuit on a 1/2 in supply, the filter protects clamping valves from condensate and chips-laden air, the low-pressure regulator limits clamp force to protect delicate parts, and the lubricator conditions the cylinder over long production runs.
Start with the port step: this unit is 1/2 in PT, one of six sizes from 1/8 in to 1 in across the GC range, so match the size to the air demand of the line and step up a size where flow demand is high. Choose the drain to suit access: automatic drain (as fitted here) suits enclosed or unattended installations, manual drain suits supervised points, and the differential-pressure default drains on load change. The standard filter grade is 40 um; specify the W option for 5 um where finer protection is needed. Gauge scale is selectable (MPa, psi or bar) and this unit carries the square gauge in psi; the regulator here is the low-pressure type, so confirm its exact adjustment range with us against your line pressure. Thread is PT as standard, with G (BSPP) and NPT available as order options, and a mounting bracket is included.
Because flow is published as curves rather than a single rated figure, ask us to confirm sizing against your application before ordering.
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 number, so we do not quote a figure that could mislead your sizing. Tell us your line pressure and air demand and we will confirm the flow from the datasheet curves on request before you order.
The A in the code GC30015ALF2 selects the automatic drain, so the filter bowl ejects condensate without manual attention - useful where the unit sits in an enclosed position. The L selects the low-pressure regulator type, intended for lines that run below standard working pressures; its exact adjustment range is not published on our sheet, so confirm it with us against your set pressure. The F2 selects the square gauge scaled in psi.
