The AirTAC GC300C15AC2K AirTAC F.R.L. Combination Unit, 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 GC300C15AC2K 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 built around 1/2 in PT ports. The filter element is the standard 40 um grade, and the bowl carries an automatic drain, so collected condensate is expelled without anyone having to open the drain by hand - useful on lines that run unattended. The standard regulator adjusts over 0.15-0.9 MPa (20-130 psi), an external round gauge with a psi scale is fitted so downstream pressure can be read directly, and a reverse/check valve (code K) is installed to hold the circuit against backflow. A 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 family is offered in sizes 200, 300, 400 and 600, with a choice of ports, thread forms (PT standard, with G and NPT available as order options), drain types, filter grades and gauge scales. On the 300 size the filter bowl is PC (polycarbonate); only the 600 size uses an aluminium alloy bowl. Rated flow for this family is published as curves rather than a single figure, so contact us and we will confirm the datasheet figures for your application before you order.

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 a carton-forming and sealing section of a packaging line: the filter strips water and debris from the shop-air drop, the regulator holds a steady setting for the actuated cylinders, and the lubricator mists oil to the valve and cylinder seals, while the automatic drain keeps the bowl clear between shifts.
Supplies a clamp-and-hold circuit on a CNC workholding fixture. The regulator pins the clamping pressure on the psi gauge, the 40 um element protects the directional valve seats, and the check valve helps hold the set circuit if upstream supply dips.
Conditions the air feeding conveyor-mounted blow-off nozzles and diverter cylinders: filtered and regulated air keeps nozzle behaviour consistent, the lubricator serves the diverter actuator, and the automatic drain handles the condensate that collects along a long 1/2 in distribution run.
Start with the port and size step: this unit is the 300 size with 1/2 in PT ports; if your compressed-air demand sits above what a 300 body carries, step up to the 400 or 600 frame - we will check the published flow curves against your consumption before you commit. Choose the drain to match how the unit is attended: automatic (as fitted here) suits unattended lines, manual suits periodically serviced points, and differential-pressure drain is the default alternative. Filter grade is 40 um as standard here; specify the W option if the application needs 5 um filtration. The gauge fitted is an external round gauge with a psi scale; embedded square gauges and MPa or bar scales are the other catalogue choices. Thread is PT as standard, with G (BSPP) and NPT available to order, and a mounting bracket is included. Because flow is published as curves rather than 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 the GC series as curves, not as a single rated figure, so we do not quote a number here. Send us your line pressure and air consumption and we will confirm the datasheet flow figures for this 300-size, 1/2 in unit before you order.
This unit carries code A, the automatic drain, which expels collected condensate on its own - the right pick for unattended or hard-to-reach positions. The catalogue alternatives are a manual drain, where an operator opens the drain during service rounds, and the differential-pressure drain, which is the default code when no drain letter is specified. All three fit the same GC300 body.
