The AirTAC GC300C15ALC2K AirTAC F.R.L. Combination, PT1/2 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 GC300C15ALC2K 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 size 300 unit is configured for a PT1/2 (1/2 in) port with standard PT thread, a 40 um filter element with automatic drain, and a metal bowl on the filter stage. The regulator is the low-pressure type and is fitted with a round pressure gauge reading in psi; a reverse/check valve is also fitted, and the mounting bracket is included. Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GC line covers sizes 200, 300, 400 and 600 with port sizes from 1/8 in up to 1 in, and options including manual or differential-pressure drains, a 5 um filter element (code W), square or round gauges with MPa, psi or bar scales, G (BSPP) or NPT threads, and bracket variations. Flow is published as curves rather than a single rated figure, so we confirm flow and 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. 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-C1 filter, GR300-C1 regulator and GL300-C1 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 pneumatic grippers and clamps that position panels on an automotive robotic weld line, with the check valve holding the circuit against backflow.
Supplies the cylinder-driven fillers, cappers and case packers on a bottling conveyor with water- and particulate-free air at a stable, lubricated pressure for consistent machine cycling.
Conditions the shop-air drop that runs pneumatic nailers, staplers and sanders in a furniture workshop, keeping moisture and swarf out of the tools while the lubricator mists oil to the air motors.
Size 300 with a 1/2 in PT port suits lines running moderate-to-high air demand; step up to 400 or 600, or down to 200, as your flow requirement and piping dictate. Drain choice is real: automatic (as coded here) empties the bowl without attention, manual needs an operator, and the differential-pressure default bleeds only when the pressure drop warrants it. The filter grade is 40 um as coded; specify W for 5 um where finer particulate removal matters. The gauge is a round type on a psi scale; square gauges and MPa or bar scales are alternatives. Thread is PT as standard, with G (BSPP) and NPT available to order, and the bracket is included.
Because flow is published as curves and not a single rating, ask us to confirm sizing against your application before ordering.
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-C1 regulator with a GF300-C1 filter on that branch.
AirTAC publishes flow for this series as curves, not as a single rated figure, so we do not quote one number. Send us your operating pressure and air demand and we will confirm the flow figures from the datasheet for this exact configuration before you order.
A means an automatic drain: the filter bowl discharges collected condensate on its own, with no operator action. The alternatives in this series are a manual drain (you drain it yourself) and the differential-pressure drain (the default when no letter is coded), which bleeds when the element pressure drop calls for it. This unit is supplied with the automatic drain and a metal bowl.
