The AirTAC GC30008LC2G AirTAC F.R.L. Combination G1/4 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 differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The AirTAC GC30008LC2G is a three-piece F.R.L. combination: a separate air filter, a pressure regulator and an oil-mist lubricator assembled into one air-treatment set. This size 300 configuration is built with G1/4 ports, a differential-pressure drain on the filter bowl, a 40 um standard filter element and a low-pressure type regulator, with a round gauge reading in psi. The polycarbonate bowls let you see condensate and oil levels at a glance, and the mounting bracket is included.
This is a genuine AirTAC part. The GC series is available in sizes 200, 300, 400 and 600 with a choice of ports, drain types, filter grades (40 um standard, 5 um optional), gauge scales (MPa, psi or bar) and PT, G or NPT threads. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures 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: GF300-08 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.

Installed at the drop of a pneumatic press circuit, the set filters water and scale from plant air, holds the press cylinder supply at the set low-pressure point and mists oil for cylinder and valve seal life.
Feeding spray guns in a finishing booth, the 40 um element strips water and pipe scale that ruin finish quality, the regulator holds a steady gun supply pressure and the lubricator is set dry or lightly oiled as the gun requires.
On cartoning and wrapping machinery with many small cylinders and air jets, the combination protects downstream valves from condensate, keeps actuator pressure stable and lubricates the cylinders that cycle all shift.
Start with the port size: this unit steps up to G1/4 in the size 300 body, so check it against your line's flow demand before ordering - larger sizes carry larger ports. The differential-pressure drain flushes the filter bowl automatically as the pressure differential builds, with no timer or operator input. The 40 um element is the standard grade for general plant air; if you need finer filtration, the 5 um (W) option is available in the same family. The round gauge in this code reads psi; MPa and bar scales are alternatives. Thread is G here, with PT as the standard and G/NPT as order options, and the bracket is included.
One honest note on sizing: flow for this series is published as curves, not a single rated figure, so send us your application details and we will confirm the right size from 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 GR300-08 regulator with a GF300-08 filter on that branch.
AirTAC publishes flow for the GC series as curves, not as a single rated number, so there is no one figure we can quote. Send us your application details and we will confirm the sizing against the datasheet curves before you order.
The L in the model code marks the low-pressure type regulator. Its exact adjustment range is not published on the sheet we work from, so confirm the range with us against your set pressure before ordering. The round gauge fitted to this unit reads in psi.
