The AirTAC GC30015ALF2WK AirTAC F.R.L. Combination 1/2 in PT 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 5 µm element, a automatic drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC30015ALF2WK 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 300 size with a PT1/2 port, fitted with a 5 um filter element (the finer of the two published grades), an automatic drain that expels collected condensate without manual attention, a low-pressure-type regulator, an embedded square gauge scaled in psi, a reverse/check valve, and a mounting bracket.
This is a genuine AirTAC part. The GC family is published in 200 / 300 / 400 / 600 sizes with a choice of PT, G or NPT thread, differential-pressure, automatic or manual drains, 40 um or 5 um filtration, standard or low-pressure regulation, and gauge scale options. Rated flow is published only as curves rather than a single figure, so ask us to confirm the datasheet figures 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 a workshop pneumatic press with filtered, regulated and lubricated air at 1/2 in line size, with the automatic drain keeping condensate out of the valve stack during long production runs.
Conditions the air feeding the cylinders and air tools in a robotic assembly cell, where the 5 um element protects close-tolerance components and the lubricator mists the actuator seals.
Supplies the diverters, stoppers and clamp cylinders on a packaging conveyor line, with the psi-scaled gauge letting operators set the low working pressure the station needs.
Choose the size and port step (200 / 300 / 400 / 600, with ports from 1/8 in to 1 in) against the air demand of the circuit; the 300 size with a PT1/2 port suits lines running 1/2 in supply piping. Where a bowl is fitted, pick the drain: automatic (as here) for unattended condensate removal, manual for periodic draining, or the differential-pressure default. Select 40 um standard filtration or the 5 um W grade when downstream components need finer air, and match the gauge scale to your shop standard (MPa, psi or bar).
This unit is the low-pressure (L) regulator type, so use it where the working pressure sits below the standard regulator's range; the exact adjustment span for the low-pressure type is not published and we will confirm it on request. Thread is PT as standard, with G and NPT available as order options, and a bracket is included. Because flow is published as curves rather than a single rating, 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 only as capacity curves, not as a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the flow and datasheet figures for the GC300 at PT1/2 on request before you order.
The filter bowl carries an automatic drain, so collected condensate is expelled without anyone opening a manual valve, which suits unattended or enclosed installations. The element is the 5 um W grade rather than the 40 um standard, giving finer particulate removal upstream of the regulator and lubricator. The regulator on this unit is the low-pressure (L) type; its exact adjustment range is not published, and we will confirm it on request.
