The AirTAC GC300C08LC2 AirTAC F.R.L. Combo, Low-Pressure, 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 GC300C08LC2 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 PT1/4 (1/4 in) port. The filter element is the standard 40 um grade and the bowl uses a differential-pressure drain, which bleeds accumulated water automatically whenever the pressure differential across the element is high enough, so no daily manual draining is needed. The regulator is the low-pressure type and carries a fitted round gauge scaled in psi, and the lubricator mists oil into the downstream air for tool and cylinder life. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). A mounting bracket is included.
This is a genuine AirTAC part. The GC family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and with choices of drain type, 40 um or 5 um (W) filtration, gauge style and scale, PT, G or NPT thread, and standard or low-pressure regulation. Flow is published as curves rather than a single rated figure, so ask us and we will confirm the datasheet figures for this exact model 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. 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.

Feeds filtered, regulated and lubricated air to the stopper, pusher and clamp cylinders along a packaging conveyor line, with the low-pressure regulator holding a gentle setting for light-duty actuation and the psi gauge giving operators a local reading.
Serves a bench of pneumatic screwdrivers and riveters in an assembly cell: the 40 um filter strips water and pipe scale, the lubricator carries oil mist to the tools, and the differential-pressure drain keeps condensate moving out without a daily bowl check.
Supplies a laboratory or QC test bench where instruments and small pneumatic fixtures need clean, lubricated air at a low, stable pressure, with the round psi gauge letting technicians verify the setting at the point of use.
Start with the port step: the 300 size takes a 1/4 in port, and the larger the size (200/300/400/600), the larger the port and the more flow the unit passes - match the step to your line's air demand rather than oversizing blindly. Drain choice matters: differential-pressure (this model) drains itself under load, automatic (code A) drains on a cycle, and manual (code M) needs someone to open the bowl. Filtration is 40 um standard; specify 5 um (code W) only where downstream valves or tools need finer air. This unit is the low-pressure regulator type - if your circuit runs at conventional shop pressures, the standard type may suit better, and we can confirm the low-pressure adjustment range from the datasheet on request. Gauge scale is psi here (MPa and bar scales are also available), and the thread is PT as standard with G (BSPP) and NPT as orderable options. Because flow is published as curves, not a single rating, send us your application details 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-C0 regulator with a GF300-C0 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 inlet pressure and the air demand of your equipment, and we will confirm the flow figures from the datasheet for this exact model on request.
The L in the code marks the low-pressure regulator type, intended for circuits that run below conventional shop pressures. Its exact adjustment range is not published in the material we hold, so ask us to confirm it from the datasheet. If your line runs at standard pressures, the standard-type GC300 may be the better match.
