The AirTAC GC30015ALF2G AirTAC F.R.L. Combination G1/2 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 GC30015ALF2G is a three-piece AirTAC GC F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one air-preparation set. This configuration is size 300 with 1/2 in ports threaded G (BSPP). The filter element is the standard 40 um grade and carries an automatic drain, so collected condensate is expelled without manual attention. The regulator is the low-pressure type, and an embedded square gauge reading in psi is fitted so the set pressure can be read at a glance. The filter and lubricator bowls are polycarbonate (PC), and a mounting bracket is included.
This is a genuine AirTAC part. The GC family is available in sizes 200, 300, 400 and 600 with a choice of ports, thread options (PT standard; G and NPT to order), drain types, 40 um or 5 um (W) filtration, gauge style and scale, and standard or low-pressure regulation. 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 filtered, regulated and lubricated air to workpiece clamps and tool-change cylinders on a machining cell, with the psi gauge letting the setter hold the clamp pressure the fixture was designed for.
Supplies the pushers, diverters and sealing cylinders along a carton packaging conveyor, where the automatic drain keeps condensate out of the valves during long unattended shifts and the lubricator mists the cylinders.
Prepares the air feeding spray guns and coating applicators on a finishing line, with the low-pressure regulator type suiting processes that run at reduced set pressures and the 40 um element protecting the gun from water and debris.
Start with the size and port: this unit is size 300 with a 1/2 in G-threaded port, one step up from the 300-size 3/8 in option, so match the port against your supply line and let the required flow decide the size step. The automatic drain on this unit suits unattended installations; a manual-drain version is available where you prefer controlled blowdown. Filtration is the standard 40 um grade - choose the 5 um (W) element only if downstream equipment needs finer protection. The fitted square gauge reads in psi; MPa or bar scales and an external round gauge are alternatives. Thread is G here, with PT standard and NPT available to order, and a bracket is included for panel or wall fixing. Note that this is the low-pressure regulator type, intended for circuits set well below standard operating pressures. Flow for this family is published as curves, not a single rating, 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 the GC series as curves, not as a single rated figure, so we do not quote a rated flow number. Tell us your application and line conditions and we will confirm the flow and sizing from the datasheet on request before you order.
The L in the code marks the low-pressure regulator variant, intended for circuits set below the standard regulator range. The exact adjustment range for this variant is not published in the standard table, so ask us to confirm it on request. The rest of the decode is standard: 1/2 in G-threaded ports, automatic drain, 40 um filtration, square psi gauge, and bracket included.
