The AirTAC GC300C08MLC2K AirTAC F.R.L. Combination, PT1/4 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 GC300C08MLC2K is an AirTAC GC-series three-unit F.R.L. combination: a separate filter, regulator and lubricator built as one air-preparation unit. This configuration is size GC300 with a PT1/4 (1/4 in) PT thread port, a metal bowl on the filter section, a 40 um standard filter element and a manual drain. The regulator is the low-pressure type, a round external gauge scaled in psi is fitted, and a reverse (check) valve is included. A mounting bracket is supplied. Maximum inlet pressure is 1.0 MPa (145 psi) and the working 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 from 1/8 in to 1 in, and with catalogue choices of drain type, filter grade (40 um standard, 5 um optional), gauge style and scale, thread (PT standard; G and NPT to order) and bracket. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet 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-C0 filter, GR300-C0 regulator and GL300-C0 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.

Feeding impact wrenches, nutrunners and air ratchets on an automotive assembly bench: the filter removes water and particulate, the low-pressure regulator holds the setting the tools were set up with, and the lubricator delivers oil mist to the air motors.
Supplying pick-and-place and carton-sealing cylinders along a packaging conveyor, where filtered, regulated and lubricated air supports repetitive stroking through a full shift, with the psi gauge readable at the machine.
Feeding air chucks, clamps and clean-down guns around a CNC machining cell, with the fitted check valve in the circuit, the 40 um element guarding the downstream valves, and the bracket mounting the set beside the machine.
Start with the size and port step: GC comes in 200, 300, 400 and 600 with ports from 1/8 in to 1 in, so match the port to the supply line your circuit already runs. Drain type is a real choice: this unit has a manual drain, meaning the bowl is drained by hand on a routine basis, while the family also offers automatic (A) and differential-pressure (blank) drains. Filter grade is 40 um standard on this code; order the W variant where a 5 um element is needed. The gauge here is a round external gauge scaled in psi; embedded square gauges and MPa or bar scales are the other catalogue options. Thread is PT on this code as standard, with G (BSPP) and NPT available to order, and the mounting bracket is included (J-code units omit it). Flow is published as curves, not a single rating, so send us your demand figures 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-C0 regulator with a GF300-C0 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 port size and the air demand of the circuit, and we will confirm the sizing from the datasheet on request.
The M in the code is the manual drain: the filter bowl is drained by hand as part of routine checks. The same GC family is also catalogued with automatic drain (code A) and differential-pressure drain (blank). Tell us which suits the installation and we will confirm the matching code.
