The AirTAC GC300C08MLC2 AirTAC F.R.L. Combination Unit PT1/4 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 See datasheet ports, a 40 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC series is AirTAC's three-piece F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator working together as one set. This GC300C08MLC2 is the size 300 unit with a PT1/4 (1/4 in) port. The filter carries the standard 40 um element and its bowl is drained by hand via the manual drain, so it suits installations where the bowl is checked as part of routine maintenance rounds. The regulator is the low-pressure type, and this configuration includes the round pressure gauge with a psi scale. A mounting bracket is included, and the bowls on the size 300 filter and lubricator are polycarbonate (PC).
This is a genuine AirTAC part. The GC family is available in sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and with choices of drain type, 40 um or 5 um filtration, gauge style and scale (MPa, psi or bar), and G (BSPP) or NPT threads alongside the PT standard. Maximum inlet pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing). Flow for this combination is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing for your application before ordering.

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. Standard type, regulating 0.15 - 0.9 MPa (20 - 130 psi). 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-C0 filter, GR300-C0 regulator and GL300-C0 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.

Air preparation at each spray-booth drop: the 40 um element removes water and particulate before the regulator sets the line pressure the spray guns need, and the lubricator delivers an oil mist to the air tools downstream.
Feeding tool-changer clamps and pneumatic actuators on a machining centre: the filter protects the valves from water and particles in the shop air, the low-pressure regulator holds the circuit setting, and the lubricator conditions the cylinders.
Air preparation for the stopper and pusher cylinders along a bottling conveyor: the manual-drain filter bowl suits a shift-end check routine, and the oil-mist lubricator keeps the cylinder seals conditioned over long production runs.
The main choice is size: 200, 300, 400 and 600 step up in port and flow capacity, so match the size to the air consumption of the downstream equipment - we can check the published flow curves against your demand before you order. Within a size you choose the drain (differential-pressure as standard, automatic, or manual as on this unit), the filter grade (40 um standard, 5 um with code W), the gauge (embedded square as standard, or external round, with MPa, psi or bar scales - this model carries the round psi gauge), and the thread: PT is the standard, with G (BSPP) and NPT as catalogue options to order. A mounting bracket is included with this unit. The low-pressure regulator type is selected where the required working setting sits below what a standard regulator covers; its exact adjustment range is not published, so confirm it with us for your setting.
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-C0 regulator with a GF300-C0 filter on that branch.
AirTAC publishes flow for the GC series as curves rather than a single rated figure, so we do not quote a number here. Tell us your port size and the air consumption of your equipment, and we will confirm the sizing from the datasheet on request.
The filter bowl is drained by hand rather than automatically, so someone opens the drain as part of routine maintenance checks. If you prefer unattended draining, the differential-pressure (standard) and automatic drain options are available in the same size.
