The AirTAC GC30015LF2K AirTAC F.R.L. 3-Unit, PT1/2, Square psi Gauge 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 GC30015LF2K is a three-piece F.R.L. combination: a separate air filter, a pressure regulator and an oil-mist lubricator assembled as one GC300 set. It cleans compressed air (removing water and particulate down to the standard 40 um grade), regulates downstream pressure with the low-pressure type regulator, and adds oil mist for downstream air tools and cylinders. This configuration has 1/2 inch PT ports, a differential-pressure drain on the filter bowl, an embedded square gauge with a psi scale, a reverse/check valve fitted, and a mounting bracket included. The filter and lubricator bowls are polycarbonate (PC) on this 300 size. 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 port sizes from 1/8 to 1 inch, G (BSPP) or NPT thread options, automatic, manual or differential-pressure drains, a 5 um filter element (code W), gauge scale choices of MPa, psi or bar, and an optional external round gauge. Because flow is published as curves rather than a single rated figure, we confirm the datasheet and sizing figures on request before you order.

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.

Mounted at the drop of a packaging machine's air main, the set removes water and debris, holds a steady low working pressure for the machine's valves, and mists oil to the pneumatic actuators running the carton-forming and sealing stations.
Feeding the air cylinders that index and divert product on a conveyor line, the unit keeps moisture and particles out of the valves, regulates line pressure with the low-pressure regulator, and lubricates the cylinder seals for smoother stroke action.
Installed at a bench drop feeding air tools and clamping fixtures in an assembly cell, the combination delivers cleaned, regulated and lubricated air, with the psi gauge giving the operator a direct pressure readout at the point of use.
Start with size and port: the 300 size with PT1/2 ports suits lines running half-inch air mains, while smaller or larger duties step to the 200, 400 or 600 sizes. Choose the drain to match maintenance access: differential-pressure (as fitted here) drains automatically across a pressure band, automatic (code A) drains continuously, and manual (code M) needs a periodic drain. The standard element is 40 um; specify W for the 5 um grade where finer filtration is needed. This unit is the low-pressure type regulator, so tell us your working pressure band and we will confirm the exact adjustment range from the datasheet. The embedded square gauge here reads in psi; MPa or bar scales and an external round gauge are alternatives. Thread is PT as standard, with G (BSPP) or NPT available as order options, and a bracket is included.
Flow data for the GC300 is published as curves, not a single rated number, so please 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 this series as performance curves rather than a single rated figure, so we do not quote one number. Tell us your application and we will confirm the flow and sizing data from the datasheet on request before you order.
The L in the code marks the low-pressure type regulator, intended for lower working-pressure duties; the exact adjustment range for this variant is not published in the standard tables, so we confirm it from the datasheet on request. The filter uses the differential-pressure drain, which discharges collected condensate automatically across a pressure band without manual intervention.
