The AirTAC GC300C15LC2WK AirTAC F.R.L. Unit, PT1/2, 5 um Filter 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 GC300C15LC2WK is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator supplied as one set. This size 300 unit has a PT1/2 (1/2 in) port with PT thread, a 5 um filter element (code W, against the 40 um series standard), a differential-pressure drain on the filter bowl, and the L low-pressure regulator type. It comes with a round external pressure gauge reading in psi, a reverse/check valve fitted and a mounting bracket. The filter and lubricator bowls on this size are polycarbonate (PC). 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 series is available in sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, PT, G (BSPP) or NPT threads, 40 um or 5 um filtration, differential-pressure, automatic or manual drains, and gauge choices in MPa, psi or bar scales. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm sizing and datasheet figures 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-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 spray guns and air-assisted applicators on an automotive paint line, with the 5 um element and oil mist at the point of use.
Conditions the supply to the pneumatic cylinders and actuators that drive grippers, pushers and stopper gates on a bottling conveyor, combining all three functions at one line drop.
Serves a plant maintenance station feeding impact wrenches, grinders and other shop-air tools, keeping filtration, regulation and lubrication together at the drop.
Start with the size and port step (200 to 600, 1/8 in to 1 in) against the air your line consumes - because flow is published as curves, ask us to match the curve to your demand before you commit. This model carries the 5 um (W) element; the 40 um standard grade is available if your upstream air is already reasonably clean. Drain here is differential-pressure, with automatic (A) and manual (M) variants offered in the same series. The gauge on this unit is a round external type reading psi; embedded square gauges and MPa or bar scales are the other catalogue choices. Thread is PT as standard, with G (BSPP) and NPT as order options, and a bracket is included. This is the L low-pressure regulator type - confirm its adjustment range with us 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 GC300 series as curves, not as a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the flow and datasheet figures for this exact model on request.
This model carries the W option, a 5 um element, which is the finer of the two published grades; 40 um is the series standard. Choose 5 um where downstream equipment needs finer filtration, and 40 um where coarser protection is enough. Both grades are catalogue options on this series.
