The AirTAC GC30008ALC2 AirTAC F.R.L. Unit, PT1/4, 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 PT1/4" ports, a 40 µm element, a automatic drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC30008ALC2 is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one complete air-treatment set. This configuration is the 300 size with a 1/4 in PT port. The filter bowl carries an automatic drain, so collected condensate is expelled without manual intervention, and uses the standard 40 um filtration element for general-purpose water and particulate removal. The regulator is the low-pressure type, and a round gauge with a psi scale is fitted so the set outlet pressure can be read directly. The polycarbonate bowls suit this 300 size, and the mounting bracket is included.
This is a genuine AirTAC part. The GC series spans the 200, 300, 400 and 600 sizes with port sizes from 1/8 in up to 1 in, and options such as a 5 um filter element (code W), manual or differential-pressure drains, G or NPT threads, and alternative gauge scales. We confirm flow figures and full datasheet details for this model on request, since flow is published as curves rather than a single rating.

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: GF300-08 filter, GR300-08 regulator and GL300-08 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.

A three-unit F.R.L. set feeding clamping and holding fixtures that operate at reduced line pressures: the filter removes water and chips from the shop air, the low-pressure regulator holds the fixture setpoint, and the lubricator mists oil to the valve and cylinder seals.
Supplying the air cylinders that push, divert and stop product on packaging conveyors. The automatic-drain filter keeps condensate out of the directional valves during continuous shifts, while the lubricator maintains film on the cylinder walls.
A complete treatment point at a maintenance or fabrication bench where impact wrenches, grinders and riveters run off a 1/4 in drop: clean, regulated, lubricated air in one assembly, with the psi gauge giving the operator a direct pressure readout.
Start with the size and port step: 200, 300, 400 and 600 correspond to progressively larger ports and higher air delivery, so match the 1/4 in PT port of this 300 unit to your supply line and the demand of the downstream cylinders or tools. For the drain, choose automatic (as fitted here) where condensate should be expelled without attention, manual where you prefer operator-controlled draining, or the differential-pressure default. The filter element is 40 um as standard; specify the W code if your application needs the finer 5 um grade. Gauge scale can be MPa, psi or bar - this unit carries a round psi gauge - and thread can be ordered as PT (standard), G (BSPP) or NPT.
Note that this is the low-pressure regulator type, so if your line runs at reduced pressures, confirm the adjustment range against your setpoint before ordering. Flow is published as curves rather than a single rated figure, so ask us to confirm sizing from the datasheet against your application 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 GR300-08 regulator with a GF300-08 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 line pressure and the air demand of your cylinders or tools, and we will confirm the flow from the datasheet curves against your application before you order.
The A in the model code specifies an automatic drain on the filter bowl, which expels collected condensate on its own instead of waiting for an operator. If you would rather drain by hand or use the differential-pressure default, the GC series is also available with manual (M) and differential-pressure (blank) drain codes in the same sizes.
