The AirTAC GC300C15MLF2G AirTAC F.R.L. Combination, G1/2 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 GC300C15MLF2G is a three-unit F.R.L. combination: a separate air filter, pressure regulator and lubricator, each doing its own job on one compressed-air line. This size 300 set is threaded G1/2 (G/BSPP). The filter carries a metal bowl with a manual drain and the standard 40 um element, so condensate and particles are caught and emptied by hand. The regulator is the low-pressure type and is fitted with an embedded square gauge scaled in psi, so the downstream setting is made and watched at the unit. No reverse/check valve is fitted, and a mounting bracket is included.
This is a genuine AirTAC part. The GC series is offered in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and with a choice of drain type, 40 um or 5 um filtration, gauge scale, thread (PT standard; G and NPT to order) and standard or low-pressure regulation. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Flow for this series is published as curves rather than a single rating, so ask us to confirm the datasheet and sizing figures for your application.

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 treatment at assembly-line air drops: filtered, regulated and lubricated air feeds impact wrenches, nutrunners and air ratchets, with the square psi gauge letting line technicians check the setting at a glance.
Supplying a production cell where pneumatic clamps and small press fixtures run at modest settings: the low-pressure regulator holds the line where the tooling needs it, and the lubricator keeps cylinder seals and valves working smoothly.
Feeding treated air to packaging machines and conveyor actuation - diverters, pushers and baggers - where the manual-drain filter is emptied during scheduled changeovers and the 40 um element protects the downstream valves.
Start with size and port: 200, 300, 400 and 600 step up in port and flow capacity, and this unit is size 300 with G1/2 ports - match the step to the air demand of the line rather than to the pipe alone. Then set the choices this code fixes: manual drain on the filter bowl (simple hand draining, suited to attended installations), the standard 40 um element (the W code gives 5 um where downstream valves need finer air), an embedded square gauge scaled in psi (MPa and bar scales, and an external round gauge, are alternatives), and G thread - PT is the standard thread, with G and NPT available as order options. The regulator here is the low-pressure type; its exact setting range is not published in our material, so confirm it with us. Because flow is published as curves and not as a single rated figure, send us your application details and we will confirm sizing against the datasheet before you order.
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 rather than as a single rated figure, so no single flow number is quoted here. Send us your application details and we will confirm the datasheet figures and check this size 300, G1/2 unit against your air demand before you order.
The code makes this a low-pressure type regulator rather than the standard version, and it is fitted with an embedded square gauge scaled in psi. The exact setting range for the low-pressure type is not published in the material we hold, so confirm it with us; if your line runs at conventional shop pressures, ask us about the standard-type GC code instead.
