The AirTAC GC30015LF2 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 differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The AirTAC GC30015LF2 is a three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator, each doing its own job on one compressed-air line. The filter element removes water and particulate down to 40 um, the differential-pressure drain bleeds collected condensate as flow creates a pressure drop across the element, the low-pressure regulator sets a reduced working pressure downstream, and the lubricator meters oil mist into the air for downstream pneumatic tools and cylinders. This configuration is the 300 size with PT1/2 ports, a square gauge reading in psi, PC (polycarbonate) bowls, a mounting bracket, and no reverse/check valve.
This is a genuine AirTAC part. The GC series is offered in sizes 200, 300, 400 and 600 with a choice of ports, drain types (differential-pressure, automatic or manual), a 5 um element option (code W), gauge scale and thread options including G and NPT alongside 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.

Feeds spray-gun drops on a paint line where the filter strips water and pipe scale, the regulator holds a steady low working pressure at the gun, and the lubricator is set to zero or a light mist depending on the gun type.
Conditions the shop-air feed to a machining centre's clamps, tool-changer cylinders and air-blast circuits, giving the maintenance team one point to drain, set pressure and top up oil.
Supplies filtered, regulated and lubricated air to the diverters, pushers and gripper cylinders along a packaging conveyor, protecting the actuators from moisture and dirt in a shared mill air ring main.
Start with the port and size step: 200, 300, 400 and 600 step up in port and flow capacity, so match the size to the air demand of the line rather than only the existing pipe thread - here the 300 size gives PT1/2. Then choose the drain: differential-pressure (this model) drains with flow, automatic (code A) drains without intervention, and manual (code M) is emptied by hand. If finer filtration is needed, the 5 um element (code W) replaces the 40 um standard. Gauge scale is selectable (MPa, psi or bar - this unit carries the square psi gauge), and thread can be ordered as PT (standard), G (BSPP) or NPT. A bracket is included on this configuration.
One honest note before ordering: AirTAC publishes flow for this series as curves, not as a single rated number, and the exact regulation range of the low-pressure type is not stated in the published figures we hold. Send us your line pressure, required downstream pressure and air demand, and we will confirm the datasheet figures and correct sizing 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 GR300-15 regulator with a GF300-15 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. Tell us your inlet pressure, required downstream pressure and air demand, and we will confirm the datasheet curve and check the sizing for your application on request. The same applies to the exact regulation range of the low-pressure regulator type fitted to this model.
This GC30015LF2 carries the differential-pressure drain (the default): when air flows through the filter element, the pressure drop across it opens the drain and collected condensate is bled off automatically during operation. If your line runs intermittently at low flow, an automatic drain (code A) or a manual drain (code M) may suit better - both are orderable options in the same size.
