The AirTAC GC300C15AC2 AirTAC F.R.L. Combination, PT1/2, Auto Drain 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 GC300C15AC2 is a genuine AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one set. This size 300 configuration carries PT1/2 (1/2 in) ports on the standard PT thread, filters to 40 um, drains the filter bowl automatically, and regulates downstream pressure across the 0.15-0.9 MPa (20-130 psi) range. A round psi gauge is fitted so the regulated line pressure can be read at a glance, and the lubricator meters oil mist into the air stream for downstream pneumatic components. 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 family is available in sizes 200, 300, 400 and 600, with port sizes from 1/8 in to 1 in, PT, G (BSPP) or NPT threads, manual or differential-pressure drain options, a 5 um filter grade (code W), gauge scale choices of MPa, psi or bar, and an optional reverse/check valve. Flow is published in the catalogue as curves rather than a single rated figure, so we confirm flow and other datasheet values 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.

Installed at the 1/2 in air drop feeding a CNC machining cell, the set filters water and particulate from the compressed air, holds the supply pressure steady at the level the cell was set up for, and carries oil mist to the cell's air cylinders and valves.
Mounted on the supply line of a packaging conveyor's pneumatic cylinders, the combination removes condensate and pipe scale with the 40 um element, keeps line pressure constant through machine-cycle fluctuations, and lubricates the cylinders for daily shift operation.
Used to prepare the air feed for laboratory automation equipment, where the automatic drain keeps the bowl clear unattended, the psi gauge lets technicians verify set pressure, and the lubricator conditions the air reaching the machine's pneumatic actuators.
Start with the size and port step: GC200, GC300, GC400 and GC600 correspond to increasing port sizes (here PT1/2, 1/2 in) and increasing flow capacity, so pick the size whose published flow curve covers your application's air demand. Choose the drain type: automatic drain (this unit) empties the filter bowl without attention, manual drain relies on operator action, and differential-pressure drain is the catalogue default. Choose the filter grade: 40 um is standard, 5 um (code W) where finer particulate removal is needed. Gauge scale is selectable as MPa, psi or bar, and thread can be PT (standard), G (BSPP) or NPT to order. A mounting bracket is included with this configuration.
One honest note on sizing: AirTAC publishes flow for this family as curves, not as a single rated number, so please ask us to confirm the flow figure from the datasheet 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 the GC series as curves in the catalogue rather than as a single rated figure, so we do not quote one number. Tell us your application and we will confirm the flow from the datasheet for this exact configuration before you order.
This configuration carries code A, the automatic drain, which discharges collected condensate from the filter bowl without operator attention. The GC family is also available with manual drain (code M) or the catalogue-default differential-pressure drain, so you can match the drain to how the installation is attended.
