The AirTAC GC300C15MC2G AirTAC F.R.L. Combination Unit, 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 GC300C15MC2G is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one prepared air-treatment set. This configuration is built for a G1/2 (1/2 in) port with G thread, carries the standard 40 um filter element, and uses a manual drain on the filter bowl, so an operator opens the drain as part of routine checks rather than relying on an automatic or differential-pressure drain. The regulator is the standard type with a fitted round gauge scaled in psi, and a mounting bracket is included for securing the set to the machine frame or backplate. 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 available in sizes 200, 300, 400 and 600, with port sizes stepping up from 1/8 in to 1 in, and with decodable options including thread (PT standard, G and NPT to order), drain type (differential-pressure, automatic or manual), filter grade (40 um standard, 5 um with code W), gauge style and scale, and a reverse/check valve. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing figures for your application on request.

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.

Filter, regulate and lubricate the shop-air feed to CNC machine tooling and clamping circuits, with the round psi gauge giving operators a direct reading at the machine and the bracket holding the set on the cell backplate.
Condition the air feeding pneumatic cylinders and actuators on a packaging conveyor line: 40 um filtration removes water and particulate, the regulator holds a steady setting, and the lubricator carries oil mist to the cylinders.
Prepare supply air at a finishing or coating station where regulated, lubricated air is wanted downstream, using the manual drain as part of a scheduled daily check of the filter bowl.
Choose the size and port step against the air demand of the line: this unit is size 300 with a G1/2 (1/2 in) port and G thread; smaller or larger sizes in the GC range move down or up through 1/8 in to 1 in ports. Drain type is a real choice: manual (as coded here) suits attended installations with routine maintenance, while automatic and differential-pressure drains suit unattended duty. Filter grade is 40 um as standard on this code; specify 5 um (code W) where finer particulate removal is needed. The gauge on this unit is the external round type scaled in psi; embedded square gauges and MPa, psi or bar scales are the other catalogue options. Thread is G here, with PT as the standard and NPT available to order; a mounting bracket is included.
Flow for this family is published as curves, not as a single rated number, so we do not quote a flow figure here. Send us your air demand and line conditions and we will confirm the 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 the GC series as curves, not as a single rated figure, so we do not state a flow number on the page. Tell us your air demand and line pressure and we will confirm the sizing from the datasheet on request before you order.
The M in the code GC300C15MC2G selects the manual drain on the filter bowl: an operator opens it during routine checks. The catalogue alternatives are the differential-pressure drain (the default, blank code) and the automatic drain (code A), which suit installations that are not checked daily. Regulation range on this manual-drain set is 0.05-0.9 MPa (7-130 psi); with an automatic or differential-pressure drain it is 0.15-0.9 MPa (20-130 psi).
