The AirTAC GC30008MLC2G 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 manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi).
The AirTAC GC series is a three-piece F.R.L. combination: a separate air filter, pressure regulator and lubricator assembled as one air-preparation set. This GC30008MLC2G is built on the 300 size with a G1/4 (BSPP) port. The filter section carries the standard 40 um element with a manual drain, the regulator is the low-pressure type, and a round gauge scaled in psi is fitted. The bowls are polycarbonate (PC), maximum inlet pressure is 1.0 MPa (145 psi), operating temperature is -5 to 70 C (non-freezing), and a mounting bracket is included.
This is a genuine AirTAC part. The GC family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, and options for automatic or differential-pressure drains, a 5 um filter element (code W), gauge scales in MPa, psi or bar, and PT, G or NPT threads. Because flow is published as curves rather than a single rating, we 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: GF300-08 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.

Feeds filtered, regulated and lubricated air to paint-line circuits where the low-pressure regulator suits booths and guns that run below standard line pressure, while the 40 um element keeps water and particulate out of the finishing air.
Placed at the drop feeding a packaging conveyor, the set conditions air for the line's cylinders and actuators: the filter's manual drain clears collected water, the regulator holds the set pressure, and the lubricator mists oil into the supply.
Serves a machine-shop tool circuit off a 1/4 in drop: water and particulate are removed before regulation, the low-pressure regulator matches the tools' operating band, and the oil-mist lubricator conditions impact wrenches and grinders through the shift.
Step up or down through the 200/300/400/600 sizes to match the port and the flow your line needs; this unit sits at 300 with a 1/4 in G-thread port. Decodable choices on the GC family include drain type (manual here; automatic and differential-pressure are the alternatives), filter grade (40 um standard, 5 um with code W), gauge scale (this unit reads psi; MPa and bar are available), thread (PT is the standard; G and NPT are catalogue options) and bracket. The regulator is the low-pressure type; its exact adjustment range is not published, so ask us to confirm it. Flow for the series is published as curves, not a single rated figure, so send us your application and we will confirm sizing 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 rather than a single rated figure, so no rated flow number applies. Send us your application and we will confirm the datasheet flow curve and sizing for this 300-size, G1/4 unit on request.
This unit is specified with a G (BSPP) parallel thread on its 1/4 in ports. PT is the standard thread for the GC series, and G or NPT are catalogue options you select in the model code when ordering, so match the thread code to your existing fittings.
