The AirTAC GC300C15MLF2W 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 GC series is AirTAC's three-piece F.R.L. combination: a separate air filter, pressure regulator and lubricator built as one working set, so incoming compressed air is cleaned of water and particulate, regulated to the pressure the circuit needs, and carried with an oil mist to downstream components. This GC300C15MLF2W is the 300 size with a 1/2 in PT port, rated for a maximum inlet pressure of 1.0 MPa (145 psi) and -5 to 70 C, non-freezing. It carries the 5 um filter element (the finer of the two published grades) with a manual drain on its PC (polycarbonate) bowl, a low-pressure type regulator with an embedded square gauge reading in psi, and no reverse/check valve. A mounting bracket is included.
This is a genuine AirTAC part. The GC combination is published in 200, 300, 400 and 600 sizes with ports from 1/8 in to 1 in, and with choices of drain type, filter grade, gauge style and scale, thread (PT standard, with G and NPT as order options) and bracket. Flow figures for this series are published as curves rather than a single rating, so ask us to confirm the datasheet and sizing 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.

Point-of-use supply for impact wrenches, air ratchets and clamping fixtures at assembly stations, where the set cleans, regulates and oil-mist-lubricates the air feeding each drop.
Feeds carton sealers, labelers and wrapping heads on a packaging line, keeping water and debris out of valves and cylinders while carrying lubricant to the moving seals.
Supplies the pneumatic diverters, stoppers and lifters on a warehouse conveyor line, with regulated pressure to the circuit and oil mist carried to the actuators.
The real choices within the GC series are the size and port step (200 through 600, 1/8 in to 1 in), which should be stepped against the flow your line needs; the drain type on the filter (manual, as fitted here, versus automatic or differential-pressure); the filter element grade (40 um standard or 5 um, fitted here); the gauge (embedded square as standard, external round optional, in MPa, psi or bar scales); the thread (PT is standard, G and NPT are order options); and the bracket. The regulator in this unit is the low-pressure type; its exact adjustment range is not published, so confirm it with us. Flow is published as curves, 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 the GC series as curves rather than a single rated figure, so we do not quote a number here. Tell us your line pressure and the air demand of the equipment you are feeding, and we will confirm the sizing against the datasheet on request.
The L in GC300C15MLF2W marks the low-pressure type of regulator rather than the standard one. The exact adjustment range for the low-pressure version is not published in the catalogue, so confirm the range you need with us before ordering. The unit otherwise follows the standard GC decode: 5 um filtration, manual drain and an embedded square gauge reading in psi.
