The AirTAC GC30015MLF2 AirTAC F.R.L. Combination PT1/2 Manual Drain 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 manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi).
The GC30015MLF2 is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one supply package. This configuration is the size 300 body with 1/2 inch PT ports, a manual-drain filter bowl, the standard 40 um filtration grade, a low-pressure regulator type, an embedded square gauge reading in psi, and a mounting bracket included. In use it filters water and particulate from the compressed air, holds the downstream pressure the circuit needs, and adds a controlled oil mist for pneumatic tools and cylinders.
This is a genuine AirTAC part. The GC family is offered in sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, with a choice of drain type, 40 um or 5 um filtration, gauge scale, thread form (PT standard, G and NPT to order) and bracket options. Max inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so ask us to confirm the sizing figures from the datasheet for your application.

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 filtered, regulated and lubricated air to spray guns and air-assisted equipment in a paint booth line, where water and particle carry-over would spoil finish quality and the low-pressure regulator type suits circuits run below standard mains pressure.
Supplies the pneumatic cylinders and flap-folders on a carton sealer with clean air, a steady set pressure and oil mist, keeping the sealing head cycling consistently through a shift.
Conditions the air feeding pneumatic workholding clamps and tool-change actuators on a CNC cell, protecting the valves from water and grit while holding the clamp pressure the setup calls for.
Start with the port step: this unit is size 300 with 1/2 inch PT ports, one of five sizes (200/300/400/600) that step up in both port size and flow capacity, so match the size to the air demand of the circuit rather than only to the pipe thread. Next choose the drain: this code has a manual drain, where the bowl is emptied by hand at intervals; automatic and differential-pressure drains are available on the same size if you prefer draining without operator attention. Filtration is the standard 40 um grade here, with a 5 um element (code W) available where finer particle capture is needed. The gauge on this unit is the embedded square type with a psi scale; MPa and bar scales and an external round gauge are alternatives. Thread is PT as standard, with G (BSPP) and NPT as orderable options, and the mounting bracket is included. Because flow is published as curves and not a single rated figure, send us your application details and we will confirm the correct size 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 the GC series as curves, not as a single rated number, so there is no honest one-line flow figure we can quote. Tell us your application and air demand and we will confirm the sizing from the datasheet on request before you order.
The M in GC30015MLF2 means the filter bowl drains manually: someone opens the drain at service intervals and empties collected water. It suits stations that are checked regularly. If the unit will sit unattended, the same size is available with an automatic or differential-pressure drain so condensate is removed without operator attention.
