The AirTAC GC30015ALF2GK AirTAC F.R.L. 3-Unit 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 GC30015ALF2GK is a three-piece AirTAC G-series F.R.L. combination: a separate air filter, a pressure regulator and an oil-mist lubricator assembled as one supply unit. This 300-size configuration is built for 1/2 in ports with G (BSPP) thread, carries a 40 um standard filter element with an automatic drain on the filter bowl, and is fitted with the low-pressure type regulator, an embedded square gauge scaled in psi, and a reverse/check valve. The polycarbonate bowls suit the non-freezing -5 to 70 C operating window, and the maximum inlet pressure is 1.0 MPa (145 psi).
This is a genuine AirTAC part. The GC series is available in 200, 300, 400 and 600 sizes with port options from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drains, a 5 um (W) filter element option, gauge scale choices, and G or NPT thread options to order. Flow figures for this series are published as curves rather than a single rating, 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 a machining center's tool-change cylinder and spindle-clamp circuit, with the automatic drain keeping condensate out of the bowl during unattended shifts.
Conditions the air feeding pneumatic cylinders on a carton-forming and sealing conveyor, where the low-pressure regulator suits lines running at reduced set pressure and the lubricator keeps cylinder seals working.
Serves as the point-of-use F.R.L. for a multi-station assembly cell, giving each drop its own filtration, low-pressure regulation and oil-mist feed, with the psi-scaled square gauge readable at the cell.
Start with the size and port step: 300 is the mid-size frame, and the 15 position gives a 1/2 in port - step up to 400/600 or down to 200 depending on the flow your line needs. Drain choice matters in practice: the automatic drain fitted here empties the filter bowl without operator attention, while manual and differential-pressure drains are the other catalogue options. The 40 um element is the standard grade; specify the W code if your application needs the 5 um option. The square gauge is fitted here in psi scale, with MPa and bar scales available as alternatives. Thread is G (BSPP) on this code; PT is the standard and NPT is an orderable option, so match the thread to your piping. The bracket is included on this configuration.
Two honest routing notes before you order: this is the low-pressure type regulator, and its exact adjustment range is not published in the material we hold, so confirm the range against your set pressure with us first. And 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 figure, so we do not quote a number here. Tell us your line pressure, set pressure and the flow your application needs, and we will confirm the sizing from the datasheet on request.
The L in the code marks the low-pressure type regulator, intended for applications running at reduced set pressures; its exact adjustment range is not published in our material, so confirm it against your set point with us before ordering. The F2 code means the embedded square gauge is fitted and scaled in psi; MPa and bar scales are available as alternatives.
