The AirTAC GC300C15MLC2GK AirTAC G1/2 F.R.L. Combination Unit 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).
GC300C15MLC2GK is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and lubricator built up as one supply unit on a G1/2 (BSPP) port. In this configuration the metal filter bowl is manually drained and carries the standard 40 um element, the regulator is the low-pressure type fitted with an external round gauge reading in psi, and a reverse (check) valve is fitted. Maximum inlet pressure is 1.0 MPa (145 psi), the working temperature range is -5 to 70 C (non-freezing), and a mounting bracket is included.
This is a genuine AirTAC part. The GC family is published in sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 in, in PT (standard), G or NPT threads, with differential-pressure, automatic or manual drains, a 40 um standard or 5 um (W) filter element, and gauge scales in MPa, psi or bar. Flow for the GC300 is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures against 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 pneumatic clamps and swing cylinders on a welding or assembly fixture where the clamp circuit runs at a set low pressure; the regulator holds the setting and the round gauge reads it in psi.
Acts as the supply point for impact wrenches, grinders and air ratchets in a maintenance bay: the filter removes water and particulate, the lubricator carries oil mist to the tools, and the reverse (check) valve is fitted in the circuit.
Supplies filtered, regulated and lubricated air to the pick-and-place cylinders and actuators on a carton-forming or case-packing conveyor, with manual drains for a scheduled end-of-shift bowl drain.
Size up by the port and body size: GC300 with a G1/2 port sits in the middle of the GC range (200, 300, 400, 600), and the larger the size, the larger the port and the more flow the unit passes - match the step to your line's air demand. The real, decodable choices on this family are drain type (manual here; automatic or differential-pressure available), filter grade (40 um standard, 5 um with code W), gauge style and scale (this unit: external round, psi), thread (PT is the standard; G and NPT are order options) and bracket. The regulator on this unit is the low-pressure type; its exact adjustment range is not published in the material we hold, so we confirm it on request. Flow is published as curves, not a single rating - send us your application and we will confirm sizing 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 the GC300 as curves rather than a single rated figure, so we do not quote a number. Send us your line's air demand and working pressure and we will confirm the sizing from the datasheet on request.
The filter bowl is drained by hand, which suits lines with a scheduled maintenance routine. If you prefer unattended draining, the GC family is also available with automatic (A) or differential-pressure (blank) drains; drainage capacity figures are not published, so ask us to confirm details on request.
